Gomamon is the partner Digimon to Joe Kido throughout the Digimon Adventure continuity, including the film *Digimon Adventure: Last Evolution Kizuna*. A marine beast-type Digimon, Gomamon has white fur for body temperature regulation, purple markings, an orange-red mane, and prominent claws capable of breaking solid ice. Red fur along its back bristles when angered, reflecting its emotional state. Gomamon's core personality blends sarcasm, perceptiveness, and a free-spirited nature. He frequently challenges Joe's seriousness, encouraging him toward spontaneity. This dynamic continues as Gomamon supports Joe through emotional conflicts, using wit and insight to counterbalance Joe's cautious personality. Gomamon's evolutionary line progresses from Pichimon (Fresh level) to Bukamon (In-Training), then Gomamon (Rookie), Ikkakumon (Champion), and Zudomon (Ultimate). In continuities like the *Digimon Adventure* PSP game and *Digimon Adventure tri.*, Gomamon can achieve Vikemon or Plesiomon as Mega-level forms. Significant evolutionary moments include digivolving to Ikkakumon to combat Unimon in *Digimon Adventure*, and later to Zudomon when Joe prioritizes Takeru Takaishi's safety, activating the Crest of Reliability. During *Digimon Adventure tri.*, Gomamon temporarily reached Vikemon to confront an infected Imperialdramon. In *Last Evolution Kizuna*, Gomamon primarily utilizes his Champion and Ultimate forms (Ikkakumon and Zudomon) during battles, with no new evolutionary stages introduced. In *Last Evolution Kizuna*, Gomamon participates in the global conflict against Eosmon, a Digimon abducting DigiDestined by trapping them in a dreamlike state. He joins other partnered Digimon in combat against Eosmon at its Mega level. The film establishes that Digimon partners separate from their human counterparts as the humans approach adulthood and their "infinite potential" diminishes. While the narrative focuses significantly on Taichi and Yamato's impending separation from Agumon and Gabumon, Gomamon and Joe face the same existential deadline. Gomamon remains present until the film's conclusion, implying his separation occurs shortly after the depicted events. The story confirms all original DigiDestined eventually part ways with their Digimon partners as they mature into adulthood.
