Takeshi Goda, universally known as Gian, stands as a central figure within the Doraemon franchise, marked by his imposing physical presence, aggressive nature, and status as the neighborhood bully. His appearance features a large build, tan skin, black hair, and typical attire of a shirt (varying in color across adaptations) paired with trousers and blue shoes. Gian possesses a volatile and tyrannical personality, frequently dominating peers through intimidation or force. He lives by the self-serving motto "What's yours is mine and what's mine is mine," often confiscating toys, comics, or Doraemon's gadgets from others—especially Nobita Nobi—under the pretense of "borrowing." His aggression extends to animals, manifesting in attempts to harm creatures like rabbits or tanukis, sometimes prevented by Doraemon's interventions. Despite his bullying, Gian exhibits a paradoxical dependence on Nobita, regularly assigning him tasks or demanding his company regardless of Nobita's wishes. Notable traits include his delusional self-confidence in his horrendous singing voice and poor cooking skills, which he forces upon others through unsolicited concerts or meals, remaining oblivious to their flaws. His interests encompass baseball, where he captains a team named "The Giants"; losses often trigger verbal or physical abuse towards teammates like Nobita and Suneo Honekawa. Gian's family life reveals deeper layers. He harbors extreme fear of his mother, who runs a grocery store and physically punishes him for neglecting chores or bullying. His father features less prominently. He demonstrates fierce protectiveness towards his younger sister, Jaiko, supporting her manga-writing aspirations and sometimes exploiting Doraemon's gadgets to assist her, though his overbearing nature strains their relationship. His peer relationships are complex. Suneo Honekawa serves as his primary accomplice in bullying but also endures Gian's occasional violence and exploitation; their dynamic fluctuates between camaraderie and resentment. Nobita bears the brunt of Gian's cruelty, yet Gian sporadically reveals hidden concern, such as rescuing him from danger or offering medicine during illness, hinting at latent loyalty often depicted in films or special episodes. Shizuka Minamoto receives comparatively gentler treatment, though she criticizes his behavior, and Doraemon alternates between aiding Gian and recoiling from his aggression. Gian's character experiences recurring, ultimately unsustainable efforts toward self-improvement. Realizing his unpopularity during a birthday incident might prompt a resolve to change with Doraemon's guidance, but mockery from peers like Suneo typically provokes immediate relapses into aggression, highlighting his struggle with his temper. In extended narratives and films, he consistently demonstrates courage and solidarity, defending friends during crises. His future portrayal as a devoted father and business owner further reflects inherent, though inconsistent, goodness beneath his abrasive exterior. Muku, the family dog, receives sporadic care from Gian, though Jaiko primarily tends to him; Gian's occasional kindness to Muku contrasts his usual neglect.
