List of Regular Show characters

These characters appear in the American animated television series Regular Show, created by J. G. Quintel for Cartoon Network.

The series revolves around the daily lives of two friends, Mordecai (a blue jay), and Rigby (a raccoon). They work as groundskeepers at a park, and spend their days trying to avoid work and entertain themselves by any means. This is much to the chagrin of their boss Benson (a gumball machine) and their coworker Skips (a yeti), but to the delight of Pops (a lollipop). Their other coworkers include a pig-nosed green humanoid nicknamed Muscle Man (real name Mitch Sorrenstein), and a ghost nicknamed Hi-Five Ghost (real name not mentioned in the show).

Mordecai (voiced by J. G. Quintel) is a 6'0" 23-year-old anthropomorphic blue jay who works as a groundskeeper at The Park. He has been best friends with Rigby ever since childhood. Mordecai is more conscientious, intelligent, responsible, and mature about his actions than Rigby is, which sometimes leads to him opposing Rigby when he is the cause of some kind of chaotic problem, albeit unintentionally. Even though Mordecai dislikes his job, he is often willing to put up with it begrudgingly as opposed to Rigby, who is more open about his hatred towards his job and prone to avoid work as much as possible. However, Mordecai usually sides with his friend, occasionally going along with Rigby's attempts to get out of work and the two generally stick together through their adventures.

Mordecai loves to play video games and is a better player than Rigby, he also demonstrates decent strength, such as carrying large boulders, fighting the death bear, never getting hurt by Rigby's punches, and being able to punch Rigby across an entire room with ease. He can sometimes become caught up in his emotions, often letting them get the better of him. However, he is usually quick to apologize to others if he has hurt them and most of the time takes the lead in fixing a situation.

Mordecai's romantic life is the subject of several episodes, particularly his crush on Margaret Smith, a red-breasted robin who worked as a waitress at a local coffee shop. Mordecai would often hang out with her, along with Rigby and Eileen Roberts. Mordecai had many failed attempts at starting a relationship with her due to either his own nerves or Margaret having a boyfriend at the time. He attempts to date other people in "Yes Dude Yes" and meets CJ. Though the two have a lot in common they part ways at the end of the episode. Mordecai and Margaret finally begin to date in the fourth season until Margaret decides to leave for college, thus ending their relationship and causing Mordecai to go into a depression.

Mordecai later bumps into CJ at a New Year's Eve party and they start dating soon after. CJ and Mordecai's relationship is strained due to CJ seeing Mordecai and Margaret having fun together on several occasions. He eventually decides to take a break from dating in "Dumped at the Altar", after his relationship with CJ didn't work out.

In the episode "Camping Can Be Cool", it is revealed that he attended art school before being employed at The Park; however, he did not finish school due to his bad portrait skills, which were revealed in the episode "Bad Portrait". He is shown to have an outgoing mom, who embarrasses him around his girlfriends and also made a highlight reel of Mordecai's most embarrassing moments, as seen in "Maxin' and Relaxin'".

In the epilogue to "A Regular Epic Final Battle", Mordecai quits The Park, parts ways with Rigby, moves to New York City, and returns to making art. He opens a successful exhibition and meets a bat woman whom he eventually marries and starts a family.^[1] Mordecai's wife was not given a name in the show. Head writer Matt Price, on Reddit, gave her the name Stef when asked about it,^[2] and writer Owen Dennis stated on Tumblr that there had not been previous plans to give a name to the character.^[3]

Rigby

Rigby
First appearance	"The Pilot" (2009)
Last appearance	"A Regular Epic Final Battle: The Power" (2017)
Created by	J. G. Quintel
Voiced by	William Salyers
In-universe information
Species	Raccoon
Gender	Male
Occupation	Park Groundskeeper (formerly)
Affiliation	Park Workers Mordecai and the Rigbys Dome Subjects
Family	Sherm (father) Barbara (mother) Don (younger brother)
Spouse	Eileen Roberts (wife)
Children	Two unnamed daughters

Rigby (voiced by William Salyers) is a 3'5" 23-year-old anthropomorphic brown raccoon who works as a groundskeeper at The Park. He has been best friends with Mordecai since childhood and is more prone to slacking off than Mordecai is. Rigby is hyperactive and extremely mischievous, which sometimes puts him at odds with Mordecai. He mostly lives for simply having a good time and relaxing, which he achieves occasionally through selfish acts like lying or cheating. His immaturity often gets the better of him and puts others into trouble, often causing many of the chaotic and surreal problems that arise in The Park. Mordecai punches him on the arm for this as a running gag. Nevertheless, he is very kind-hearted at least deep down, so he sticks closely to his friends and feels terrible remorse for his choices which clearly reflect a lack of foresight rather than cold-blooded sociopathy.

Like Mordecai, Rigby loves to play video games, but he is the worse of the two. He is also shown to be the weakest of The Park workers, although he has surprised them on a few occasions. Rigby's lack of strength was a major plot point in the episode "One Pull Up", in which Rigby had to pass a company physical and keep his job by performing one pull up. He has a younger brother named Don, whose height and physique lead people to believe that he, not Rigby, is the elder brother.

It is hinted in the episode "'Ello Gov'nor" that Rigby's last name may be Riggerson, however, this has neither been confirmed nor denied by J. G. Quintel.

Eileen Roberts, a female mole who works at a local coffee shop, previously alongside Margaret Smith, has strong feelings for Rigby and makes this very obvious. He originally did not reciprocate her feelings and harshly ignored her several times, but he quickly begins to warm up to her and implies that he likes her, as well. In "Dumped at the Altar", Rigby reveals to Mordecai that he and Eileen have been dating for 3 months.

Rigby is allergic to eggs, as evidenced in the episode "Eggscellent" when Rigby tried to eat a 12-egg omelet to win a trucker hat and went into a coma due to a severe allergic reaction. Rigby also faced death several times and actually died four of those times, but was swiftly resurrected. As of Rigby's Graduation Day Special, Rigby has finally graduated from high school.

In the epilogue to "A Regular Epic Final Battle", Rigby quits The Park and moves in with Eileen. They eventually get married and start a family, and it is likely that Rigby is a househusband, because he is seen teaching his two daughters how to play video games, and he does not have enough skills to be employable for a decent-paying job, so Eileen would earn more money than him as an educated college graduate.^[1]

Benson Dunwoody

Benson
First appearance	"2 in The AM PM" (2006)
Last appearance	"A Regular Epic Final Battle: The Power" (2017)

In-universe information
Full name	Benson Dunwoody
Species	Anthropomorphic gumball machine
Gender	Male
Occupation	Drummer (for Hair to the Throne) (formerly) Construction Worker (in "Exit 9B") Park Manager (formerly) Park Owner (currently)

Spouse	Pam Dunwoody
Significant others	Ashley (ex-girlfriend) Monica (ex-girlfriend) Patricia (ex-girlfriend) Audrey (ex-girlfriend)

Benson Dunwoody (voiced by Sam Marin) is a temperamental, middle-aged 5'4" gumball machine who works as the manager of The Park. Thought he is at constant odds with Mordecai and Rigby; he is only occasionally depicted as being at odds with Muscle Man and Hi Five Ghost. He tends to yell at his employees when they are slacking off and not working, and frequently tries to get them fired. His full name is revealed in the episode "The Dome Experiment".

Despite being at constant odds with them, Benson becomes more friendly toward Mordecai and Rigby after calming down in the episode "Benson Be Gone" and the three subsequently bond as the series progresses (he especially softens up to Mordecai in particular due to his maturity, unlike Rigby with whom he remains at odds with). He is skilled at stick hockey and formerly played the game competitively. Benson has a strong love for music, and is revealed to be a former drummer for the band "Hair to the Throne" in the episode "150 Piece Kit": having performed a seemingly impossible drum solo for the band during his youth.

Benson used to date Audrey, a human woman who lives across from him in his apartment complex. It is revealed that they broke up in "The Real Thomas", in which Benson starts to date an undercover Russian spy named Natalia, although she is later eaten by a whale.

In the episode "Pam I Am", Benson develops feelings for one of the dome scientists named Pam and they go on a 'date'. However, Dr. Langer witnesses the 'date' and makes a new rule that forbids the dome staff from dating anyone who works at the park. At the end of the episode, it is implied that Benson and Pam will date once the dome is gone. During the beginning of the episode "Fries Night", Benson contacts Pam back on earth, to which she revealed that having a "long distance" relationship with Benson because he is now in space is too difficult for her. She states that the reason for the break up is that she doesn't know when or if he will ever return to earth again. They both agree to become friends even though Benson later gets depressed from yet another break up with a woman he really cared for.

In the epilogue to "A Regular Epic Final Battle", Benson becomes Mr. Maellard's caretaker, who eventually leaves behind his possessions as well as the ownership of The Park to Benson: the only person as close to him as Pops, possibly due to his gratitude toward Benson for all his hard work as a steadfast park manager. Despite this, a running gag throughout the series features Mr. Maellard forgetting Benson's name.

He gets back together with Pam, and they apparently adopt Applesauce as well as a variety of cats.

Pops Maellard/Mega Kranus

Pops
First appearance	"The Naive Man from Lolliland" (2005)
Last appearance	"A Regular Epic Final Battle: The Power" (2017)
Created by	J. G. Quintel
Voiced by	J. G. Quintel (2006) Sam Marin (2005, 2010–2017)
In-universe information
Full name	Mega Kranus
Nickname	Pops Maellard/Pops
Species	Lollipop
Gender	Male
Occupation	Entomologist (in "Exit 9B") Park Manager
Affiliation	Park Workers Mordecai and the Rigbys Dome Subjects
Family	Mr. Maellard (adoptive father; deceased) "Anti-Pops" (brother; deceased)

Pops Maellard (later revealed to be Mega Kranus; voiced by Sam Marin) is a cheerful and somewhat naive 6'2" lollipop man who resides at the house in The Park and always talks in a whiny-like tone. His adoptive father, Mr. Maellard, is the owner of The Park. Pops tends to be very ecstatic about everything, often exclaiming "Good show!" or "Jolly good show!" when he is happy about something. When something bad happens, he will instead say "Bad show."

Pops tends to dress and act like he is in the late 1800's to early 1900's and utilizes technology and slang from that time period. He carries small butterscotch lollipops in his wallet, sincerely believing that they are real money, much to everyone's confusion. He is an upright gentleman who is very kind and well-mannered to everyone. He is also very sensitive, often becoming upset or crying if his feelings are hurt. He has strong interests in poetry, wrestling, music, nature, animals, and games. Despite being an elderly man, he is very childish and is often oblivious to serious things around him. Because of this, the group frequently looks after him, especially Benson.

Pops has also been shown to have immense strength on several occasions, despite his slim build. In the episode "Prank Callers", it is shown that Pops was once a more serious and mature man back in the 1980s. However, when Mordecai and Rigby had been sent back to that time and accidentally hit him with a golf cart, he is shown to have turned into his zany self. Pops once owned a British doll named Percival, or Percy, who turned his back on him and tried to kill Pops in "Terror Tales of the Park". Pops is also one with nature, but lost it until he tries to find the answer to get it back, as shown in "Catching the Wave".

In Season 8, Pops is revealed to be the universe's Chosen One due to being born with telekinetic abilities and ever since he is one with nature back in some previous season's episode, as well as having an evil version of himself with the ability to erase a person from existence. Pops' destiny is to kill Malum Kranus, his brother, to prevent the destruction of the universe. In "A Regular Epic Final Battle", it is revealed that his real name is Mega Kranus. Pops also realizes that the best way to defeat Malum Kranus is with kindness. Pops gives Malum Kranus a hug and the two fly into the sun, killing them both in the process, and the universe is saved. In Heaven, Pops' voice is heard saying his catchphrase 'Jolly Good Show' as a VHS of the show ejects itself from a Hanatronic TV which was seen in "Eileen Flat Screen", and the series itself concludes.

Skips/Walks

Skips
First appearance	"The Pilot" (2009)
Last appearance	"A Regular Epic Final Battle: The Power" (2017)
Created by	J. G. Quintel
Voiced by	Mark Hamill
In-universe information
Full name	Skips
Species	Yeti
Gender	Male
Occupation	Park Groundskeeper Mechanic
Affiliation	Park Workers Mordecai and the Rigbys Dome Subjects Guardians of Eternal Youth
Significant others	Mona (girlfriend, deceased) Sheena (ex-girlfriend)
Relatives	Quips Quippenger (cousin)

Skips (born Walks; voiced by Mark Hamill impersonating Harvey Fierstein) is an 6'5" anthropomorphic white yeti who works as a groundskeeper at The Park. He is the strongest and smartest of The Park workers and they almost always turn to him for help, as he usually knows how to solve the chaotic problems that arise; however, he isn't always right. Whenever he is asked for help, he generally says, "I've seen this before", and then presents a solution. He sometimes serves as a peacemaker during times of conflict, using his imposing stature and demeanor as a way of discouraging others from getting out of control in heated situations (though he is also prone to outbursts of his own on rare occasions).

As his name suggests, he is always skipping rather than walking or running. The reason why he always skips is discovered in the episode "Skips' Story," where it is learned that he had a girlfriend many years ago, prior to him becoming immortal. The two of them constantly skipped. When she died, he vowed to only skip to honor Mona, his dead girlfriend and the only person he ever loved.

He is a diligent worker and is very skilled at his job; however, he suffers from a lack of knowledge of computers and other kinds of newer technology, which was seen in the episode "Skips vs. Technology" where Mordecai and Rigby jam a printer and crash the computer whilst printing a card for Skips thanking him for his efforts to save them from being fired by Benson for their antics. Aside from this, he is very experienced and knowledgeable, as he is immortal and has been alive for hundreds of years.

In the episode "Free Cake", it is revealed that he must perform a ceremonial dance every year on his birthday to renew his immortality. The episode "Skips' Story" reveals that he was given immortality by the Guardians of Eternal Youth to fight Klorgbane, a bully who inadvertently killed his girlfriend, Mona, during a fistfight.

In the epilogue to "A Regular Epic Final Battle", Skips remains working at The Park while having a new part-time job as a mechanic, satisfied with his life.

Mitchell "Muscle Man" Sorrenstein (voiced by Sam Marin) is a 4'11" 25-year-old obese, green-skinned man who works as a groundskeeper at the Park. He is very erratic and immature, often pulling pranks and joking around. He enjoys telling "My mom!" jokes, botched attempts at "Yo mama" jokes, much to the annoyance of everyone except Hi Five Ghost, his best friend. Although he can be rude due to his ego, he is ultimately shown to be polite and caring toward his friends. At times, he can burst out on a rampage if he is greatly angered. A running gag throughout the show is Muscle Man always 'knowing a guy', often getting the main cast out of difficult situations.^[4]

His father, Muscle Dad, enjoyed the same attitude for pranks and jokes, but died in the episode "Trucker Hall of Fame". His elder brother John, who goes by Muscle Bro, is also seen throughout the series. Muscle Man originally shared a rivalry with Mordecai and Rigby throughout the first two seasons. He began to get along with them and treat each other as friends when the third season began. His girlfriend, Starla, shares a similar appearance to him and the couple constantly disgust other people when they publicly kiss and show affection to each other. His real name was revealed to be Mitch Sorrenstein in the episode "Muscle Woman" (in an early episode, it was originally listed as 'Steve Musselman', this was changed for unknown reasons). He is revealed to be Jewish in "The Christmas Special" in which he reveals he celebrates Hanukkah.

In "Power Tower", it is revealed that he gained the nickname "Muscle Man" from his early years of bodybuilding and actually being in excellent physical condition, but he found that life very boring and gave it up. In "The End of Muscle Man", he proposes to Starla and the two become engaged and they later marry in "Dumped at the Altar".

In the epilogue to "A Regular Epic Final Battle", upon returning home Muscle Man discovers he has a three-year-old daughter. He and Starla live out their days in their trailer park home and have numerous children. It was revealed in "Trailer Trashed" that the trailer was his prize for winning a hot dog eating contest.

Hi-Five Ghost (voiced by Jeff Bennett in season one, then by J. G. Quintel for the remainder of the series) is a 2'6" ghost with a hand extending from the top of his head who works as a groundskeeper at The Park. Hi-Five Ghost is best friends with Muscle Man and frequently gives him high fives to accompany his jokes, as he genuinely finds most of Muscle Man's jokes amusing. Because of his name and appearance, he is frequently called by his nickname, "Hi-Fives", and sometimes simply as "Fives". Hi-Five Ghost rarely speaks throughout the first three seasons of the series, but he is given more dialogue from seasons four to eight. His father was introduced in the episode "See You There", as well as his older brother Low Five Ghost, who works as a police officer.

In the episode "The Postcard", Hi-Five Ghost reunited with a human girl named Celia whom he had befriended at a cafe after waiting four years to receive a postcard from her in Prague.

In the epilogue to "A Regular Epic Final Battle", Hi-Five Ghost and Celia become a married DJ duo and tour the world together. They have a son together.

Significant others	Slasher (ex-boyfriend) Angel (ex-boyfriend) Various ex-boyfriends Mordecai (former romantic interest and ex-boyfriend)
Relatives	John (cousin) Darryl (cousin) Various extended family members

Margaret Smith (voiced by Janie Haddad-Tompkins) is a 5'10" anthropomorphic robin who works as a waitress at a local coffee shop. She was good friends with her co-worker, Eileen. Mordecai had a huge crush on Margaret and frequently found excuses to go to the coffee shop to see her. She has a cousin named John who has an artificial wooden leg. The rest of her family are all birds like her and Mordecai, except for her father Frank, a strong and stern human. Margaret returns Mordecai's feelings for her and the two begin to finally date in the fourth season. They broke up in the season finale when Margaret leaves for college. In the episode "Eileen Flat Screen", Margaret returns now as a news reporter, which no one notices. In "Merry Christmas Mordecai", Mordecai becomes nervous when he hears that Margaret will be there. After several awkward encounters (thanks to Mordecai), they finally manage to have a normal conversation with both acknowledging that they had some good times. This leads to a montage of memories, ending with a memory of a kiss on a roller coaster. Unfortunately, when the scene flashes to the present, they accidentally kiss on the lips and are shocked when they notice CJ watching them. CJ runs out of the house and leaves while Mordecai runs upstairs to find his phone; he notices that all of Margaret's stuff is there and Eileen tells him she is staying as an intern. Mordecai is stunned when he hears the news and didn't know what to say about Margaret staying with Eileen from now on.

As of "Sad Sax", Mordecai and Margaret are still just friends, and Mordecai makes it up to CJ by telling her the truth.

In "1000th Chopper Flight Party", Mordecai is still awkward with her presence and afraid to screw up, even to the point of letting Rigby constantly mess up the Party as a diversion just to keep her away from him. When he finally is declared as the lucky guest to ride Chopper 6 for its 1000th flight, he finds it hard to say no and joins. Margaret tries to talk to him, but Mordecai awkwardly resists until she scolds him for his attitude in desire for their friendship. Mordecai then lifts the tension with a joke and they finally start to have a fun chat. This however angers CJ, who misinterprets it as them rekindling their love, and she causes havoc with her storm cloud ability. Mordecai tries to save Margaret, but she calms CJ when she reveals that she is in a relationship with news anchor, Del Hanlon, which stuns Mordecai and surprises her parents.

In "Not Great Double Date", Mordecai seemed upset that Margaret had a boyfriend, but still said that she seemed happy with Del and that he liked him. When she confessed that Del was not her boyfriend and that she was tired of feeling like a tourist around her friends because of the tension with CJ, he felt sad about her feeling this way about herself and was pretty interested to know that she still had feelings for him when she was asked by CJ.

In "Just Friends", Rigby and Eileen go to the presentation of martial arts Don, leading to Mordecai and Margaret spending a night that has romantic moments. A chef named Daisuke shows them their future using magical sauce. It is revealed that if, and when, Mordecai and Margaret get together, they will get married, have children, buy their own houseboat, and die peacefully after 50 happy years. Mordecai and Margaret agree that their future looks like it will be really great, but that they are still young and should take it easy on relationships for the time being. At the end of the episode, the two agree to remain just friends, with future Margaret looking down on them and inquiring how long they can be just friends, and future Mordecai stating that "only time will tell."

In "Rigby's Graduation Special", she was very worried as she watched Mordecai and cried as the other park workers being shot into space, even saying his name in concern. However, in the epilogue to "A Regular Epic Final Battle", she is only seen running toward Eileen and hugging her upon her return. She surprisingly does not end up with Mordecai and is not seen with the group 25 years later, though she becomes a muse for Mordecai's art after Mordedai quit his job at the park to pursue art.

Head writer Matt Price stated on Reddit that the idea was that Mordecai and Margaret would find their own paths in life.^{[5][unreliable source?]} On Tumblr writer Owen Dennis stated that reality shows that many people who initially date one another early on end up with other people, contradicting narrative arcs of many Western entertainment media.^[3]

Gender	Female
Occupation	Waitress (formerly)
Affiliation	Dome Subjects
Family	Unnamed father
Spouse	Rigby (husband)
Children	Two unknown daughters

Eileen Roberts (voiced by Minty Lewis, a writer/storyboard artist for the series) is a 3'8" anthropomorphic mole who works as a waitress at a local coffee shop, previously alongside Margaret. She has a crush on Rigby, but he initially found her annoying. She is notable for her intelligence and displays many skills and hobbies throughout the series including dancing, sewing, and astronomy. One of Eileen's odd personality quirks is her affinity for sea turtles, which is referenced in a few episodes. She's a recurring character in seasons 2–7, and becomes a main character in season 8.

Eileen first appeared and met Mordecai and Rigby in the episode "Brain Eraser", in which she was puzzled by the former's awkward behavior toward Margaret. She also appears in the episode "Do Me a Solid", in which Rigby learns of Eileen's crush on him. Although he does not reciprocate, he still goes along with it for a while. Since the episode "Camping Can Be Cool", Rigby has warmed up to, and fully reciprocated towards Eileen. He thought very highly of her and praised her actions throughout the episode. In the episode "Diary", Rigby admits that he finds Eileen to be attractive when she is not wearing her glasses, but it is also revealed that she cannot see without them, suggesting she has at least moderate myopia. In the episode "One Pull Up", Eileen helps Rigby train for the Park employees' physical test and he shows his gratitude by hugging her (and crushing her due to his enlarged physique). In the episode "Eileen Flat Screen", it is revealed that Eileen and Rigby have been spending more time together. In "Dumped at the Altar", Rigby tells Mordecai that he and Eileen have been dating for three months. In "Rigby's Graduation Day Special", Eileen finally graduates from college at the same time Rigby finally gets his high school diploma. As she is cooking for a graduation party for her and Rigby, when the guys press the button that sends them and the park into space, Eileen gets stuck with the guys. In the epilogue to "A Regular Epic Final Battle", she and Rigby move in together and start a family. It is unknown if she has a job or not; but based on her husband's unemployability for a decent-paying job and the need for one spouse to stay at home to care for the daughters, it is implied that she is the spouse who goes to work, and for pretty high salary as an educated college graduate.

She first appeared in the episode "Yes Dude Yes", in which Mordecai started dating her after thinking Margaret was engaged. After learning that Margaret was not getting married, he almost immediately forgets about CJ, leading to an ugly break up at the coffee shop in which she revealed that she can transform into a deadly storm when really angry and assumed this form in three episodes. After Margaret leaves town for college, CJ and Mordecai meet each other at the New Year's Eve dance in the episode "New Year's Kiss", unwittingly kissing each other at midnight. The following episode, "Dodge This", continues this story days after the kiss with CJ and Mordecai competing against each other in a dodgeball tournament. This leads to awkwardness between the two in the final round of the dodgeball tournament and they are forced to address their issues before the Intergalactic Dodgeball Council. They later agreed just to be friends. At the end of the episode "I Like You Hi", Mordecai asks CJ out and she agrees to go out with Mordecai. In the following episode, "Play Date", CJ and Mordecai plan to go out, but are interrupted by Death's 300-year-old son, Thomas. In the Season 5 finale "Real Date", Mordecai saves her life when the founder of Couple Corral McIntyre tries to get them to break up and they officially become a couple. In "Merry Christmas Mordecai", she sees Mordecai and Margaret accidentally kiss, and drives off very upset. In "Sad Sax", Mordecai tries to reconcile with her after receiving advice from "Sad Sax Guy", and they finally get back together.

Relatives	Unknown

Nikolai (seasons 4–7) (voiced by Roger Craig Smith) is a young anthropomorphic goat who is of Ukrainian origin and was trained by the KGB as a ruthless spy, and who later sent him to work for the Russian organization M.O.M.M. (Ministry of Meadow Management), a KGB agency that struggled to find out what made American parks up to date and wealthy. To fix Russia's outdated parks, M.O.M.M. sent out Nikolai on a covert operation to obtain the park and bring it back to Russia. During his undercover mission, he changed his identity to "Thomas" and presented himself as an intern for credits in college in "Exit 9B" (in which he made his debut), working as an unpaid intern who calls his "mom" on a regular basis and is often reproved by his coworkers, most notably by Muscle Man. He is usually reluctant to be involved in the surreal and chaotic adventures that arise in The Park, often asking if he has to be part of the situation, to which they insist that he must. There are times when Nikolai becomes personally invested in maintaining his cover, such as using a robot to pose as his "mom" in "The Thanksgiving Special", and wearing spy attire disguised as a Halloween costume (a slice of pizza, which he had to wear until Thanksgiving Day upon losing a bet in "Terror Tales of the Park III"). When the other Russian spies that were deployed with him carry out the final phase of the plan to bring The Park to Russia in "The Real Thomas", he finally reveals his true identity to the park crew and explains why he is really there. When Nikolai learns the plan is really to destroy the Park through a loophole in Russian/American relations, he turns on his fellow spies for being lied to (along with some persuasion by the park crew to remind him of the good times they had as friends, despite the constant poor treatment he received from them for being an intern), and returns the Park to American soil before going on the run from both sides. He makes several cameos after this, usually in some sort of disguise. Eventually, he returns in "Guys Night 2," revealing himself to be tired of his old life as a spy and wanting to move on to a new life. He feels his only option is to go into hiding forever, but first he enjoys one final hang with the park crew. He made non-speaking cameos in later episodes. In “Rigby's Graduation Special”, he makes a brief cameo by proposing a toast to the park dome taking off into space while in his submarine, hinting that he is aware of their mission and Pops's destiny.

Mr. Maellard

Mr. Maellard
First appearance	"Dizzy" (2011)
Last appearance	"A Regular Epic Final Battle: The Power" (2017) (non-speaking)
Created by	Sean Szeles Shion Takeuchi
Voiced by	David Ogden Stiers
In-universe information
Full name	Mr. Maellard
Gender	Male
Occupation	Park Owner
Significant other	Pops (adoptive son)

Mr. Maellard (voiced by David Ogden Stiers) is an elderly lollipop who owns The Park and is also Pops' adoptive father. He first appeared in the episode "Dizzy". Mr. Maellard is very impatient towards Benson (similar to Benson's impatience towards Mordecai and Rigby) and Mr. Maellard blames their shenanigans on Benson (as he expects Benson to take responsibility for them as the park manager). He purposely mistakes Benson's name a lot in some of the episodes in which he appears (using "Ballbucket", "Beanbag", etc.). Mr. Maellard finally got Benson's name right and started to respect him better in the episode "Benson Be Gone" due to Benson coming to his rescue when he was captured by Susan, a demon disguised as a woman whom he had hired as the park manager after demoting Benson, and also gave Benson his old job back. As the series progresses, he turns from a ruthless and shallow businessman into quite an eccentric character with a deeper personality. He sends the gang to space in the final season and in the episode "The Ice Tape", Pops and the gang find out that Mr. Maellard is not his real father and he found him as a baby, adopted him during an expedition, and kept him safe until the time was right for Pops to fulfill his destiny, but Mr. Maellard tells Pops that no matter what, he always thought of him and loved him unconditionally as his real son. In the series finale, when the park gang returns from space after a three-year absence, Mordecai notices Mr. Maellard staring up at the sky in grief, shedding a tear for his late son. It is presumed that he is caretaken by Benson for the remaining days of his life until he dies immediately before the 25th reunion of the Park, when the gang erect a statue of him next to the statue of Pops. Ogden Stiers was a voice acting veteran; this marked his final recurring voice role before his death in March 2018.^[6]

Baby Ducks/Hyperduck

The Baby Ducks (voiced by J. G. Quintel, William Salyers, Sam Marin, Mark Hamill, and Roger Craig Smith) are a group of four baby ducks whom Mordecai and Rigby found in a fountain in the park in the episode "A Bunch of Baby Ducks". They have shown their ability to fuse together to form a giant duck-headed man called Hyperduck when they fist-pump simultaneously. They return in the episode "A Bunch of Full-Grown Geese" to help Mordecai and Rigby get rid of the park by the evil, titular geese who soon turn into a similar giant monster. The duo helped the baby ducks upgrade their giant form and succeeded in defeating the geese. They also appeared in "Exit 9B" where they helped fight the park worker's past villains in their giant form. Before their official debut, an unrelated group of baby ducks are some of the things sent to the moon by Rigby in the episode "The Power". In "Brilliant Century Duck Special", they again help the park gang fight the geese, who are now helping businessmen that are attempting to destroy the park. In the series finale, they help the Park gang fight Anti-Pops and Streaming.

Guardians of Eternal Youth

The Guardians of Eternal Youth (voiced by David Kaye, Robin Atkin Downes, Roger L. Jackson, J. G. Quintel, and Troy Baker) are a group of five infant-like beings for whom Skips must perform a ceremonial dance to maintain his immortality otherwise, he will be stripped of his eternal life. Skips also attended school with them before they granted him his immortality. They also designed and built Skips' Fists of Justice, which allowed him to defeat Klorgbane the Destroyer. Mordecai and Rigby found out about this and because they accidentally injured Skips, they took over and defeated Klorgbane (but not before he killed Archibald, one of the guardians), who vowed to return before he was sent flying away. They also appeared in "Exit 9B", where they help the park workers fight off their past villains. In the episode "Quips", the leader's name is revealed to be Reginald, and in "Skips' Story", the names of the other three guardians are revealed to be Oswald, Boswald, and Griswald. In Regular Show: The Movie, they participate in the fight against Mr. Ross and his timenado. In the final season finale, they help the park gang fight Anti-Pops and Streaming.

He works as a valet for the Guardians and also made an appearance in the episode "Cool Bikes" where he served as Mordecai and Rigby's lawyer. In "Gary's Synthesizer" it is revealed that he has an old synthesizer that keeps him alive, but if any of its cables come unplugged or are tampered with, he will disappear. Although king of his home planet Synthos, he left to travel the galaxy and his half-brother David took over. When Gary found out how strict David was as king of Synthos, he battled him in a music battle and won. David was destroyed in the sun and his disk was smashed by two Synthos people, Robert and Keith, who were nearly executed by David. Then Gary declared that from then on Synthos would have no ruler. In the final season finale, he helps the park gang fight Anti-Pops and Streaming.

Death

Death (voiced by Julian Holloway in a cockney accent) is the grim reaper who, in several of his appearances, makes bets with park workers and declares that he would take their souls if they lose. For example, he tried to take the immortal life of Skips during his first appearance in the episode "Over The Top". He also tried to take Muscle Man's soul twice in the episodes "Dead at Eight" and "Last Meal" and even attempted to take everyone's souls in "Skips Strikes". Despite these evil intentions, he also helped the groundskeepers defeat the villains resurrected by GBF Jr. in the episode "Exit 9B". Death also has a son named Thomas, a 300-year-old demon (voiced by Michael Dorn) who can speak, although Death does not know this. He later helped them retrieve Mr. Maellard's guitar in "Guitar of Rock", and in "The End of Muscle Man" where the others think he's trying to take Muscle Man's soul, but was only there to deliver him a ring. He also makes an appearance in the episode "Cheer Up Pops" after the gang invites him to a party to help them cheer Pops up. In this episode, he said that they could count on him to help in the final battle. In the series finale, he helps the park gang fight Anti-Pops and Streaming.

The God of Basketball (voiced by Carl Weathers) is a basketball/human hybrid who is also known as the Basketball Coach King. He apparently lives within the moon and rides in a custom designed white flying Cadillac Escalade. The God of Basketball then quickly befriends Mordecai and Rigby in "Slam Dunk" which leads him into offering them to learn how to play basketball well. When that does not go according to plan, he uses his powers to instantly grant both of them great basketball powers. The God of Basketball momentarily changes sides when he is forced to play with Muscle Man against the duo for computer rights for life. The God of Basketball also appeared when he helped Rigby to get back his hat, in the match of Rigby vs. a basketball net face-like weirdo in 'Bank Shot'.

The Phone Guardians

The Phone Guardians (voiced by Rich Fulcher and William Salyers) are five living objects (a fire in a wigwam, two tin cans connected by a string, an answering machine, a message in a bottle, and a chalkboard) who serve as protectors of phones and live in an empty universe. All members appear to lack the ability to understand emotion. They first appeared in "Butt Dial" where they threaten to erase Mordecai and Rigby from existence for hacking into Margaret's phone to erase an embarrassing message that Mordecai accidentally recorded, in which they chose to play it for Margaret at her request instead of erasing it for Mordecai. After listening to it, Margaret convinces them to release Mordecai and Rigby while saying that they've "learned their lesson."

After Mordecai and Rigby stole his moves in "Death Punchies", he was forced to shut his dojo down. He re-appears in "Sandwich of Death" as the owner of Death-Kwon-Do Dojo Pizza and Subs and helps them retrieve the cure for Benson, who ate the Death Sandwich incorrectly. It is revealed that he had a falling out with his master, who tried to kill him when they tried to retrieve the cure. He returns in "Death Kwon Do-Livery," where Mordecai, Rigby, and his apprentice attempt to help him go through a surgery operation for his new stomach. The reason is that his stomach exploded due to his Death Kwon Do Sandwich of Health, which is incredibly unhealthy. His apprentice later turns on them due to how his master had treated him, and that he had snuck in after working hours to eat it and thus he needs a replacement stomach. Despite his attempts to steal the stomach, the duo stop him and manage to save the sensei.

Dr. Reuben Langer

Dr. Reuben Langer (voiced by Troy Baker) was the new leader of the Dome project who first appeared in "The Button." After Mordecai, Rigby, and the gang froze the original leader, Dr. Dome, Langer was sent in his place to continue the Dome project. He told the gang not to push the button yet, as it was hinted that Langer and his crew were working on the rockets for The Park. In the episode "Rigby's Graduation Day," he sent a fax to the gang to push the button to launch them into space for their mission: protect and train Pops against his long-lost evil brother, Anti-Pops.

Chance Sureshot

Chance Sureshot (voiced by Matthew Mercer) was one of Rawls' men working at the space station. Alongside Toothpick Sally and Recap Robot, he helps save the park from the Reaper Bots. His first appearance was in "Cool Bro Bots." He was killed when he tried to stop Anti-Pops from killing Pops and the gang with a laser in "Space Escape."

In the episode "Space Escape", Mordecai and Rigby told Rawls that Anti-Pops erased an employee from Comet Stop. Rawls ordered everyone to get out of the Space Tree and he managed to get Mordecai, Rigby, and the gang out of the hangar but he decided to stay at the Space Tree.

Earl

Earl (voiced by Feodor Chin) is the master of Pops who first appeared in "The Ice Tape". After Maellard revealed to Pops the truth about his origin, he tells him to find Earl since he's the one who can help Pops to fight his evil brother. After the tape melted, Earl revealed himself to the Gang. Later, in the episode "The Key to the Universe", Earl tests Pops by making him do his chores, which lead to Pops unleashing his frustration on him. Earl understands Pops and in a last effort of persuasion to continue training, he shows him a fragment from a previous Universe and also showed him the decision of Pops not fighting his Brother. Upon this revelation, Pops later ran away and hid from everyone but Mordecai and Rigby calmed him down. After Pops was fully relaxed, Earl threw a lemon towards him which activates his powers and soon declares that his real training will begin. During the episode "No Train No Gain", Earl senses the growing threat of Anti-Pops' powers, so he used a training montage with some of his favorite music to train Pops quickly. This however made Mordecai and Rigby bored with his music, and they used their own music to speed up Pops's own training. Earl was shocked and told them that Pops goes too fast and out of control. The gang and Earl was able to stop Pops speeding, but ended up benefiting Pops' strength and Earl realizes he's ready. In "Kill'Em with Kindness", he is erased by Anti-Pops. In the final season finale, when both Pops and Anti-Pops died together and restoring everything in the universe that has been destroyed by their cause in balance, meaning that Earl is revived.

The Seer

The Seer (voiced by Yvette Nicole Brown) is the all-knowing person who first appeared in "Meet the Seer". She was mentioned by Earl in "Kill'em with Kindness", that she was the only one that will reveal the location of the final battle.

After Reel to Reel and Black and White were killed by Streaming, she would later reveal the location of the final battle to Pops and the gang. She was killed when Planet Nielsen exploded, but when Pops and Anti-Pops died, she was revived

Father Time

Father Time (voiced by Alan Sklar in "It's Time" and Fred Tatasciore in Regular Show: The Movie) is a large being made of clocks who wears a purple bowler's hat. He lives within an invisible house in the space-time continuum. In the episode "It's Time" Mordecai accidentally traveled to his dimension when he tried to destroy several clocks using a microwave oven out of jealousy due to Rigby's relationship with Margaret, unwittingly killing Rigby in the process. Father Time got upset with Mordecai because of his jealousy and attempting to destroy his clocks. Although Mordecai had to stay in his dimension as punishment, he instead sends him back in time on a "time pony" to restart the whole thing (as house guests annoy him since they can't see his invisible furniture) after accepting Mordecai's apology, but warns him that he'll be sorry if he ever does this again. He also appears in Regular Show: The Movie where he convinces Rigby to apologize to Mordecai for lying to him to restore their friendship. His body has also been falling apart due to Mr. Ross's time-nado, but after Mr. Ross's defeat, he is presumably returned to normal.

Archie the Archivist/Laserdisc Guardian

Archie (voiced by John Cygan) is a librarian, DVD/HD-DVD and Blu-Ray's father, and the protector of the remaining laserdisc player who can transform into the Laserdisc Guardian in the form of a golden crystal being. While in this form, he speaks in a language that only the Guardians of Obsolete Formats, DVD/HD-DVD, and Blu-Ray can understand. He first appears in "The Last Laserdisc Player". Mordecai, Rigby, Muscle Man, and Hi Five Ghost came to his library to rent a laserdisc player, but he points out that they're all out and takes them to the basement to prove it. When they show him the laserdisc record that they found, he reveals that they are the Disc Masters and uses that record to open the door to a secret room where the last laserdisc player and the Guardians of Obsolete Format are in and entrusts the laserdisc player to them. During the fight against the Ancient Order of the VHS, he gets injured by the VC-Arbitrator and the Disc Masters transform him to his true form, who then defeats the VHS men and the VC-Arbitrator. He is then seen watching a movie on the laserdisc player with the Disc Masters and the Guardians. He also appears in "Format Wars II" where he again helps the Disc Masters find the universal remote, which reveals that Benson is the fifth Disc Master and joins the fight against his son, DVD and his creation: Internet. When he and DVD try to reconcile, Internet betrays DVD and kills Archie. He reappears as a ghost at the end of the episode, once again watching a movie with everyone else. He is mentioned in "Meet the Seer" while DVD (now upgraded to HD-DVD) and Blu-Ray are arguing over who's better.

DVD/HD-DVD

DVD (voiced by Joel McHale as DVD and Trevor Devall as HD-DVD) is Archie's son and Blu-Ray's older brother who first appears in "Format Wars II". Although he at first starts off as a villain, he later reforms. Like Archie, he can transform into a crystal being but unlike his father, his form's color is silver and his face is displayed, therefore allowing him to speak English in his crystal form. Like the Guardians of Obsolete Formats, he can also understand what Archie is saying while he's in his crystal form. He creates a Wi-Fi Robot named Internet to seek revenge against his father for discrediting his format. During the fight against the Guardians, the Disc Masters (Mordecai, Rigby, Muscle Man, Hi Five Ghost, and Benson), and Archie, they are able to kill Betamax, Ampex Quadruplex, and Floppy Disc, but when he and Archie try to reconcile, Internet betrays him and kills his father, to the former's horror and anger. Now seeing that he can no longer control Internet, DVD then decided to help the Disc Masters defeat Internet by providing them the universal remote's code to take out the Wi-Fi server tower that's powering him. Following the battle, he is seen watching a movie along with the Disc Masters, Reel-to-Reel, and Archie's ghost. He meets them again in "Meet the Seer" alongside his sister Blu-Ray where he is now upgraded to HD-DVD and helps them fight through Planet Nielsen against Streaming (who is Internet upgraded in a new form) and his minions to find the Seer and they escape before the planet's destruction.

Like Archie and DVD/HD-DVD, she can transform into a crystal being (which is colored blue) and like her brother, can speak English in this form as her face is displayed. She can also understand Archie's speech in his crystal form. In "Cheer up Pops" they help the park gang record the memories of their past adventures so they can always remember them. In the eighth-season finale, they participate in the battle against Anti-Pops and Streaming.

Guardians of Obsolete Formats

The Guardians of Obsolete Formats are seven giant beings with heads resembling outdated machines. Four of them first appeared in "The Last Laserdisc Player" where they are awakened by the Disc Masters (Mordecai, Rigby, Muscle Man, and Hi Five Ghost) to protect the remaining laserdisc player. During the fight against the Ancient Order of the VHS, the guardian 8-Track is killed by the VC-Arbitrator. They (along with two others) return in "Format Wars II" where they help the Disc Masters find the universal remote (which also reveals that Benson is the fifth Disc Master) after finding out that the guardian Microfiche is killed by DVD. In the fight against DVD and Internet, Betamax, Floppy Disc, Ampex Quadruplex, ENIAC, and Archie are killed. The remaining two guardians: Reel-to Reel and Black and White meet them again in "Meet the Seer" where they help the park gang fight through Planet Nielsen with the help of DVD (who is now upgraded to HD-DVD), Blu-Ray, and Microwave (who sacrifices himself to save the others) until they are both killed by Streaming (who is Internet upgraded into a new form).

When the park gang attempts to pay Muscle Man back for his past pranks, they are teleported to the White Elephant's temple. He is unhappy with the park gang for wanting to get revenge on Muscle Man and violating the rules of the White Elephant Gift Exchange; which is to give gifts you don't like, not receive gifts you like, which makes it entertaining (since Muscle Man's pranks are his way of having a fun time). Because of this, they must stay in his temple for all eternity for going overboard with their revenge prank and are not allowed to open any of the gifts here. However, he does give them two options: go back and make amends, or open the gift box that he offers them. They choose to go back, but decide to carry out their revenge prank anyway when they find out that Muscle Man had pranked Rigby with what they thought was a new flatscreen TV, but was actually a box of old Chinese food. At the end of the episode, the White Elephant watches through the snow globe in the gift box that he offered to the park gang earlier, who then winks at the audience and leaves. This implies that he may have been aware of Muscle Man's prank and orchestrated the whole thing to ensure that the park gang's payback prank succeeds.

After the park returns, they got back together and presumably got married in the years to come.

He first appeared in the episode "High Score" and at one point was the universal record holder for an arcade game called "Broken Bonez" before exploded in a fit of rage when Mordecai and Rigby beat his high score. He is basically one of Mordecai and Rigby's most formidable enemies and really hates them. He is a very good liar, as seen in "High Score", saying that he devoted his life to the game "Broken Bonez" and that he played it too much his wife left him, but when Mordecai and Rigby intentionally lose the game so GBF can win, he says, "Thank you. Ha, ha, ha. Thank you for being so dumb", revealing that he didn't devote his whole life to the game, saying that it was just a hobby and he never had a wife. Mordecai and Rigby along with a crowd of people make him lose by chanting the words "broken bones", and he gives in. The game kept going and GBF desperately tried to sabotage them by trying to get them away from the game, but fails and has his fit of rage. His head blows up, with brain goo coming out. Contrary to his statement about not having a wife, it was revealed in the episode "Exit 9B" that he had a son who attempted to bring back his father along with other deceased villains to have their revenge, yet the park workers and their allies managed to send Garrett Bobby Ferguson and the other villains back into the afterlife, taking his son with him.

However, Rich forcefully takes the suit by sacrificing his own men to kill the tailor and commit suicide themselves, but only the suit lives and manage to escape from Rich. Sometime later, they found out that the suit is now worn by Benson and wants him to give up the suit. However, Benson refused because he had no heart to care for the suit.

For doing so, Huge Head plans to steal Pops's identity as revenge. He eventually returned in the episode "Men in Uniform" where it is revealed that he has been stalking and plotting revenge against Pops for the last four years. However his "plotting" mostly consisted of him hiding in the bushes while saying "Wait! Not yet...". Eventually he would finally get his chance to attack Pops when an Ugly Hole was formed from some hideous uniforms merging. However, when he attacked Pops, he soon realized that he was being sucked into the hole as well for being so hideous, but planned to drag Pops along with him. Luckily, he was stopped by Muscle Man who was also being sucked into the hole, but instead hit Huge Head, which sent him into the Ugly Hole. However, his head was too big and ended up getting stuck between dimensions, leaving him as a large floating head floating in midair. Fortunately for Huge Head and the park, this proved to be quite beneficial for both of them as his freaky appearance drew in much attention to the park and to Huge Head as well, who was driven to joyful tears upon finally getting the fame and attention he so dearly desired. He is seen again in the episode "The Key to the Universe", but is already dead as his head is now a skeleton and is still floating in midair.

Just as he was about to win the turducken, to his dismay, Mordecai and Rigby came in with their own Thanksgiving song: "What Are You Thankful For?". Richard was so disappointed that their song was better than his own, so he decided to steal the turducken from them since Farmer Jimmy wouldn't let him buy it. When Mordecai and Rigby caught up to him, he revealed that he didn't want to win the turducken so he could eat it, he wanted the golden wishbone from inside it, due to the fact that it actually grants wishes. He hired thousands of people to help him with his business, but no-one ever thanked him in return because they spent time with their families. So he planned to use the golden wishbone to have Thanksgiving to himself, and receive the thanks that he always wanted. Mordecai and Rigby wouldn't let him get away with it, so there was a quarrel between the three (with help from their friends) on Richard's blimp until they are kicked out of the blimp by Richard, who didn't know they had swapped the wishbone with the spoons Rigby used for their performance.

Benson bought his products to keep Mordecai and Rigby from slacking off, but they manage to constantly evade him, causing Benson to accidentally summon him to the park to watch over everybody and as a result, he cannot leave until they die (due to the contract that Benson signed without even reading it). After spooking everyone with his gazes, Mordecai challenges him to a staring contest in which Peeps must leave if Mordecai wins, but if Peeps wins, he will harvest their eyes.

Rigby cheats to win, but later regrets it and feels ashamed when Mordecai (wearing a blonde wig) makes friends with blonde men and joins the group, who take Rigby hostage and force him to be turned into a blonde in the end. At that point, Rigby confesses to cheating on the bet to Mordecai, who frees him. Mordecai then reveals his wig to the blondes, which prompts them to attempt to kill the two.

He was the most sophisticated doll of his day, with 250 phrases stored inside. Yet the only real phrases we heard him say had to do with an obsessive desire to draw on peoples' faces. Percy not only spoke of his obsession, but it was discovered that he was also an autonomous, "living doll" who actually carried out his intentions and threats of drawing on peoples' faces. He drew on Pops's face after Pops tried to throw him away, and when Pops tried playing teatime with him after Mordecai and Rigby threw him away, Percy became aggressive and wanted to draw on Pops's face even more. Mordecai and Rigby tried to rescue Pops, but Percy escaped and went into the basement. When Mordecai, Rigby, and Pops went after him, Percy knocked Mordecai and Rigby unconscious with a shovel. Percy demanded Pops to bring him a marker so he could draw on Mordecai and Rigby's faces, but then Pops stood up for himself and told Percy that it's not cool for a grown man like him to play with dolls and that Percy must go away.

This led him to seek revenge on Rigby. He later lurked around Pops's House and used his dark magic to turn Rigby into a nice-looking house. Later that night when it was dark, Muscle Man was on the porch and then saw him driving his car to the front of the house and comes out invisible. Muscle Man tells him to change Rigby back and to get out of there, as well as loading his shotgun telling him not to ask twice. The Halloween Wizard then teases him and asks Muscle Man if he has any clever jokes about his mom, Muscle Man tells him not to talk about his mom so he starts firing in random directions, to no avail. Everyone else watches him shooting the gun but Muscle Man gets knocked over. The wizard then drags him across the grass, yelling and holding his gun up in the air while being dragged and fires the gun a few more times before he goes into the woods. Mordecai, shocked, asks if they saw that. Then there is a knocking on the door, which opens and reveals Muscle Man, who has had his skin ripped off, showing only muscle (inferring that the Wizard had skinned him). Muscle Man says, "I told you I was ripped", then falls over and dies after that and scares the others then the phone rings. Hi Five Ghost goes to answer it, after Skips tells him not to, and answers the phone saying, "Hello?". The wizard then says "Good-bye!" and sucks him into the phone and turns him into liquid that squirts onto Mordecai and Skips. Mordecai is then knocked unconscious when the wizard throws him against the bookshelf. Benson and Pops see this and they both scream and run into different rooms.

Since he behaved and talked oddly, the townsfolk thought that he was a wizard, and tried to murder him. Before they could, he put his soul into the house and exclaimed he would show them all and return in 200 years when everyone talked and acted like him, and he would be king of the world. When he realized everyone in his time would be long dead by then, he vowed to come back in the form of a murderous poltergeist to haunt and kill whoever is inside of the house, but before doing so, he signed his house over to Mr. Maellard. Unfortunately for Townhouse, his predicted time of return bypassed the eighties, when he would have been in style. Meaning now, instead of being far too ahead of his time, his mannerisms were considered old fashioned and out of touch. 200 years later on Halloween night, Benson told his fellow park workers the story of Jebediah as well as a scary story about him, which involved Mordecai, Rigby, Pops, Muscle Man, and Hi Five Ghost trying to escape from him after taking on a dare to survive the whole night in the house but are one by one killed, afterwards proceeding to tell them that he was indeed a real person.

When inside the restroom, he first asked Pops for some toilet paper. He then turns into a werewolf and attacked him and then bit Pops to turn him into a werewolf so he can take his place.

He was a good prankster and a great dad. He made his ultimate prank by leaving Muscle Man a note after his death, the note asked Muscle Man to spread his trucker hat ashes over the Trucker Hall of Fame and said that it was his last wish and final prank from beyond the grave.

This gets so bad that after almost everyone gets offended Reggie throws a temper tantrum and almost destroys the seven layer dip. After this, Skips suggests that Quips does his routine at a kids show and it works out great. Quips makes his appearance in a few episodes and has inspired a fan base for his famous catchphrase, "Zingo!"

Carty

Hecho En "Carty" Mexico (voiced by Toby Jones), is the golf cart Mordecai and Rigby use as their way of transportation. His most distinctive appearance was when Mordecai and Rigby accidentally bring him to life (with soda spilled over his engine) while having to replace him in "Out of Commission". After doing many activities, Carty dives into sea with fireworks firing from his trunk as a final activity to do before going to the dump. After finding out he was going to stay (due to Benson being unable to afford the new cart thanks to an accounting error), Mordecai and Rigby fished him out, repaired him, and drove him back. After these events, Carty could no longer speak or move by himself. He mistakenly believes that his name is "Hecho En Mexico" because that's what is written on him ("Hecho en Mexico" means "Made in Mexico" in Spanish and is actually meant to indicate where the cart was manufactured).

Johnny Skydiver

Johnny Skydiver (voiced by Steve Blum) is a skydiver and a friend of Muscle Man who flies the airplane and lives on an airfield and appeared in Rigby in the Sky with Burrito.

Suit

An outfit which is simply called Suit (voiced by Dean Cameron) is a suit-like cybernetic talking exo-suit that Benson wears in "Benson's Suit". He was created by his father, a tailor, to serve an evil boss like Rich Steve. His father refused to accept $10 since it was not enough, so Rich took the suit by force and killed his father along with Rich's guards. He later escaped from Rich after his father died, until Benson found him and wore it without knowing who the suit was. Thought it was an ordinary suit and quickly gets dirty when Benson stained it. The next day, the suit cleaned himself suddenly and appeared in front of Benson. He later revealed to Benson who he was and praised Benson as a worthy boss. He then claimed that he would help him to manage slackers like Mordecai and Rigby. When Rich Steve found him, the suit and Benson fought back and defeated Rich Steve. In the end, knowing so many evil bosses are still after him, he tells Benson to "wash" him in the washing machine in Inferno Mode to destroy him, but before he is "washed" for the greater good of peaceful kind, they admit that they will never forget their times together.

Desdemona "Mona" (voiced by Grey DeLisle), was Skips' girlfriend who knew him in the 19th century under his former name Walks. She appeared in "Diary", "Exit 9B", and had a major role in "Skips' Story".

They first appeared on The Thanksgiving Special. Not much is known about Rigby's parents, but they seem very proud of Rigby, even though he is lazy and rarely gets things done. When Rigby was in high school, he was expelled and his mother had to come pick him up. She was upset and tells him that "You're always making so much trouble for yourself". Whenever Sherm yells, makes fun of Rigby, or talks to Don, Barbara sometimes defends Rigby. In "Rigby Goes to the Prom" It is shown that he highly favors his younger son, Don, over Rigby, and thinks that Rigby is a loser and a screw up who messed up him and his family's lives to make up for his own short comings. Rigby manages to maneuver Sherm's prized car to the bottom of a mountain after Sherm lost control while driving and nearly went over a cliff (which he blamed on Rigby), confronting his dad about how even though he's getting his GED and bettering himself, that he still won't trust him and he cares more about his car and younger son than his first son. Afterwards, he appeared to have more respect for Rigby.

However, unknown to his parents, Rigby had more experiences involving more dangerous situations to survive in than Don, until they finally acknowledged him, particularly on their elder son's graduation speech about the situations he was in. As they were heading to the party, they saw the park going up into space and worriedly watch their elder son go up.

Benson stops the fighting, quickly has Mordecai and Rigby fired and makes them leave before offering Chad and Jeremy the job. They turn it down due to what they had been through and leave, much to Benson's dismay. This also allows Mordecai and Rigby (who didn't actually leave the park) to keep their jobs. The duo may also both suffer with anger management issues, where they become very hostile to Mordecai and Rigby, using violence as their first resort against them when they begin to interfere in their job. They later make a cameo appearance in "Every Meat Burritos". Their names are a reference to the band Chad & Jeremy.
