Goromaki Kondou, whose name is also sometimes rendered as Goromaki Gondo, is a character who appears in the second season of the anime. He is introduced as a henchman belonging to a yakuza group, establishing his background in the world of organized crime and street violence.

In terms of personality, Kondou is portrayed as a formidable and aggressive fighter, particularly skilled in the brutal, no-holds-barred nature of street brawling. He is confident in his abilities and does not shy away from conflict, even against other dangerous opponents. This is demonstrated when he challenges Wolf Kanagushi, a former boxer turned yakuza, and decisively breaks his jaw in a fight.

Kondou serves a critical function in the narrative of Ashita no Joe 2, primarily acting as a catalyst for the protagonist, Joe Yabuki. After the traumatic death of his rival Toru Rikiishi, Joe has become a lost and wandering soul, unable to step back into the boxing ring. During his aimless travels, he witnesses a fight between Kondou and Wolf Kanagushi. When Kondou continues to beat Wolf even after he is incapacitated, Joe is compelled to intervene, leading to a brief confrontation where Joe effortlessly defeats Kondou with just three blows. Rather than being angered, Kondou is impressed and, as he flees from the police, tells Joe he hopes to see him again in the ring. This encounter, and Kondou's words, serve to reawaken Joe's dormant fighting spirit and help set him on the path back to boxing.

Beyond this pivotal meeting, Kondou's relationship with Joe evolves from a chance street encounter to a more direct connection to the world of boxing. Recognizing the need to regain his wild and untamed former self to face a future opponent named Harimau, Joe specifically calls upon Kondou and a group of his fellow yakuza to act as his sparring partners. This demonstrates that Joe respects Kondou's unique, unorthodox fighting abilities, seeing them as a crucial tool to rekindle the primal instincts he had lost. Kondou accepts this role, directly contributing to Joe's training and preparation for the ring.

In terms of development, Kondou's character arc is not one of deep personal change but rather a shift in his role within the story. He is introduced as an antagonist figure, a yakuza thug who uses his strength for intimidation. However, his respect for Joe's power transforms him into a supporting figure, an unlikely ally whose raw, unconventional style is exactly what the protagonist needs to overcome his psychological blocks and prepare for his toughest battles.

Notable abilities of Goromaki Kondou are tied to his experience as a street fighter. He is not a technical boxer but a brawler, described as a specialist in street combat. His approach to fighting appears to be aggressive and relentless, shown when he shatters Wolf Kanagushi’s jaw and continues his assault. This raw power and unorthodox style are precisely why Joe seeks him out as a sparring partner, implying that Kondou possesses formidable physical strength and an unpredictable, dangerous fighting rhythm that can push a professional boxer to his limits. Physically, he is consistently depicted as a large, imposing man who typically wears a suit, gloves, and a hat.
