Gian, whose full name is Takeshi Gouda, is a central character commonly known by his nickname derived from "giant," reflecting his large physical build, potentially stemming partly from obesity. He commands with aggressive and domineering behavior, frequently bullying neighborhood children, particularly Nobita. His typical actions involve forcibly taking possessions under the pretext of "borrowing," summarized by his catchphrase: "What's yours is mine and what's mine is mine." Despite these antagonistic traits, Gian reveals occasional depth and fierce loyalty, especially toward his younger sister, Jaiko. He assists her with comic book writing, sometimes utilizing gadgets obtained from Doraemon, though this often frustrates her. His personality features overconfidence in his severely flawed singing and cooking abilities, leading him to subject others to torturous concerts or meals, oblivious to their negative impact. Gian stands as the strongest and most athletically capable among the children, serving as captain of the baseball team "The Giants." He forces Nobita to join despite his poor skills, blaming him for losses and reacting abusively to defeats. His home life is marked by fear of his mother, who runs a grocery store and physically punishes him for shirking duties or bullying. Relationships with peers remain complex. While Suneo acts as his sidekick, Gian frequently bullies him, creating a dynamic of mutual exploitation and occasional betrayal. His treatment of Nobita is predominantly cruel, yet moments reveal underlying care, such as rescuing him during peril or offering medicine when ill. Shizuka receives comparatively restrained behavior, though Gian disregards her discomfort with his aggression. Character development surfaces in introspective moments, like after reflecting on his unpopularity during a birthday event. He temporarily resolves to improve with Doraemon’s guidance but reverts to aggression after mockery from Suneo and others. In broader narratives, particularly films, he demonstrates loyalty during group crises, aiding friends despite habitual conflicts. The movie *Doraemon: Ganbare! Gian!!* focuses on his character, featuring an original plot by Hiroshi Fujimoto and Motoo Abiko. Released on March 10, 2001, as a 25-minute short, it premiered alongside *Nobita and the Winged Braves*. Audience reactions noted emotional depth, with one viewer highlighting its tear-inducing impact. Gian’s dependency on Nobita is paradoxical; he demands constant interaction, imposing tasks or punishments regardless of Nobita’s objections or plans, indicating an obsessive, albeit destructive, connection. His treatment of animals includes instances of cruelty, such as attempting to harm rabbits or tanukis, though interventions occasionally curb these actions.
