He is known for his long bangs and for always wearing a worn-out beige coat and a red flat cap. Not long after birth he found himself in many orphanages and facilities. However, he quickly grew tired of the boring life and frequently escaped, eventually finding his way to the Doya Town the story takes place in.
- Joe is rude and quick to fight, but he can also be very frivolous at times. Because of his rough upbringing he is a delinquent who likes his solitude, but he later grows to appreciate his new friends and rivals. He is not very good at understanding women, and essentially only treats them nice out of giri. As a result of Rikiishi's death, he temporarily suffers from yips and cannot hit people in the temple, but he later overcomes this. This allows him to move past the loss of Rikiishi.
- He is a bantamweight and his specialties include the cross counter and the No Guard stance. He has extraordinary punching strength, fortitude, and fighting spirit, often standing up after taking killer blows and has been known to counter cross-counters (a double-cross), possessing a raw, natural talent for the sport. He has even countered double crosses with a triple-cross, implying he has high-level technical abilities. Following his fight with Rikiishi, he begins to better develop his guarding. During his fight with José, he even unconsciously uses José's own corkscrew punch against him. Near the end of the manga, more and more hints build up implying that he is becoming punch-drunk, a condition that is confirmed right before his fight with José. On several occasions it is hinted that he is aiming for the world championship not for his own sake, but for Rikiishi's, since he died fighting Joe and was considered a future world contender.

- Harimau
- Voiced by: Takashi Taguchi (Tomorrow's Joe 2)

The match was orchestrated by Yōko to rekindle Joe's wild spirit.

Most of his techniques only avoid disqualification because there are no specific rules against them.
- José Mendoza
- Voiced by: Yoshito Miyamura (Tomorrow's Joe 2), Masami Okada (film)
- José Mendoza (ホセ・メンドーサ, Hose Mendōsa) is the perfect champion who had never lost, fought beautifully and was admired by all. He takes great care of his health and family, and is constantly calm and confident, giving an aura of being truly unbeatable. A recurring theme is his immense physical strength, to the point of leaving big bruises on Joe's body by gripping him, easily forcing him into a handshake, and even bending coins with his fingers. However, Joe eventually discovers that José has one weakness; despite his speed, strength and stamina, he can't take hits nearly as well, and relies on avoiding getting hit as much as possible. He begins to break down from this during the later stages of his fight with Joe, where he loses his cool and fears for his life against Joe's unrelenting spirit. Mendoza was knocked down for the first time in his career during the fight, and even fouled Joe violently in a moment of terror. He would win the decision, but the trauma his body suffers from the fight ages him prematurely.
