Kunio-kun

"NKKK" redirects here. For Nekketsu Kōha Kunio-kun, the first game in the series, see Renegade (video game). For the strategic development company, see Nan'yō Kōhatsu.

The Kunio-kun (くにおくん) series (typically localized as River City) is a video game series started by Technōs Japan. The series is now handled by Arc System Works who purchased all of the intellectual property rights from Technōs' successor, Million Corp. The first game in the series is fully titled Nekketsu Kōha Kunio-kun (熱血硬派くにおくん), which roughly translates to "Hot Blood Tough Guy Kunio", with Nekketsu being the name of the series' title character Kunio's high school. The kun suffix after his name is an informal Japanese honorific usually applied to young males. The series originated in arcades, before appearing on the Famicom console. Kunio later became Technōs Japan's main mascot, appearing on the company's logo in several games and television commercials.

A few of the early Kunio games for the NES were localized for the North American market. These include Renegade, River City Ransom, Super Dodge Ball, Crash 'n' the Boys: Street Challenge and Nintendo World Cup, which are heavily "Americanized" versions of the Kunio-kun games. Technōs Japan has released over twenty Kunio-kun titles for the Famicom, Game Boy, and Super Famicom in Japan. In addition, licensed ports of the games were made for other platforms such as the PC-Engine (through Naxat Soft), Mega Drive (through Pal Soft) and the X68000 (through Sharp).

Development

The original game Nekketsu Kōha Kunio-kun was created by Yoshihisa Kishimoto. He pitched a semi-autobiographical game based on his teenage high school years, with the protagonist Kunio-kun loosely based on himself. Kishimoto recalled his experiences as a high school student regularly getting into fights on a daily basis, which was partly triggered by a break-up with a girl who dumped him. Kishimito was also a fan of Bruce Lee's Hong Kong martial arts films, particularly Enter the Dragon (1973). He combined elements from Lee's Enter the Dragon with that of his own life to create the concept for Nekketsu Kōha Kunio-kun. He went on to design Double Dragon (1987), which was originally envisioned as a direct sequel to the original Kunio-Kun game, before becoming a new game with a different cast and setting.^[1]

The game's title and its protagonist, Kunio (variously renamed "Alex" and "Crash Cooney" in the United States), were named after Technōs Japan's former president, Kunio Taki. Many of the later games in the Kunio-kun series, particularly those under the Downtown Nekketsu moniker, were the handiwork of two men: Mitsuhiro "Yoshimitsu" Yoshida and Hiroyuki "Mokeke" Sekimoto.

Renegade, the Western localization of Nekketsu Kōha Kunio-kun, spawned its own separate spin-off series developed by British company Ocean Software for home computers. There were two Renegade sequels: Target: Renegade (1988) and Renegade III: The Final Chapter (1989).

Characters

The following is a list of characters appearing in most of the games, ordered by the games where they first appear.

Main characters

Kunio as he appears in Downtown Nekketsu Monogatari EX. In the North American version (River City Ransom EX), he is known as Alex.

• Kunio (くにお) (full name Kunio Fu'unji (風雲児 くにお, Fu'unji Kunio) in live-action series) – the protagonist of the series, Kunio serves as the guardian of Nekketsu High School against rival schools and is the captain of his school's Dodgeball team, although he excels at other sports (such as soccer and ice hockey). Kunio first appears in the original Nekketsu Renegade Kunio-kun, where he is described as a second year student at Nekketsu High School (in the Downtown Nekketsu sub-series, he is described as a third year student, establishing a loose continuity between later games). His surname is never revealed, but the live-action television series lists his surname as Fu'unji.^[20] In some games (such as Nekketsu Hockey Club and Baseball Monogatari), he is the only student at Nekketsu to wear an all-white uniform, while at other games everyone at Nekketsu wears white. In the localized versions, he is known as a nameless vigilante in Renegade (Mr. K in the NES version), Sam in Super Dodge Ball, Alex in River City Ransom and some of its ports, and "Crash" Cooney in Crash 'n the Boys: Street Challenge. While the protagonist of the series, Kunio also later became Technōs Japan's main mascot, appearing on the company's logo in several games and television commercials.

In the original Nekketsu Renegade Kunio-kun, Riki appears as the first stage boss and serves as captain of the Hanazono dodgeball team. Downtown Nekketsu Story was the first game where Riki teams-up with Kunio (although chronologically speaking, Shodai comes first). Since then, Riki's relationship with Kunio evolved from enmity to close friendship, and he appears in the later beat-em-ups as a secondary playable character. Riki's birthdate is on May 5 and is repeating his third year in the Downtown Nekketsu sub-series. In the localized versions, he is known as Jack in Renegade and Super Dodge Ball, Ryan in River City Ransom, and Crusher in Crash 'n the Boys: Street Challenge.
