Marlinman is an aquatic Perfect Chojin who appears in the Perfect Origin Arc of Kinnikuman. He is a member of the Perfect Large Numbers, an elite faction of Perfect Chojin that arrives to challenge both the Justice Chojin and the Devil Chojin. His title is Perfect Spike, reflecting his role as a vanguard fighter. His design resembles a marlin, with a streamlined body and a prominent spike-like snout, giving him a fish-like appearance. Marlinman’s background is largely obscure; it is known that he traveled to Mount Saint Parfait, where he impressed the Perfect Chojin Mirageman and was transformed into a Perfect Chojin. His motivations align with the Perfect Chojin ideology of absolute perfection and the elimination of what they consider inferior or imperfect beings. In the story, Marlinman is tasked with fighting the Justice Chojin Atlantis. The match takes place in the River Thames in England, an environment suited to Marlinman’s aquatic nature. During the battle, both combatants inflict fatal damage on each other, and the contest ends in a simultaneous death. The result is declared a draw. This outcome eliminates both characters from the larger conflict. Marlinman’s key relationship is with Atlantis, his direct opponent, but he has no other notable interpersonal connections shown in the arc. He exhibits no character development, as his role is brief and concluded by his death. Marlinman’s notable abilities center on his aquatic physiology. He can swim at high speeds underwater and is specialized in underwater combat. He also possesses a variety of techniques that utilize water, such as spewing water from his mouth to create pressurized attacks or to manipulate the battlefield. On land, he adapts his water-based moves to maintain effectiveness, though his primary strength lies in aquatic environments. His exact moveset is not extensively detailed, but he is characterized as a capable fighter within the Perfect Large Numbers, able to hold his own against an experienced Justice Chojin like Atlantis until their mutual defeat.
