Takeshi Goda, universally known as Gian, stands as a central figure. He possesses an imposing physique marked by a large build, tan skin, and dark hair, typically seen in an orange shirt with a stripe and brown trousers. Gian's personality blends aggression, overconfidence, and flashes of vulnerability, often expressed through bullying peers like Nobita Nobi and Suneo Honekawa. He "borrows" their possessions under threat of violence if refused. Leading the neighborhood baseball team, the Giants, showcases his competitive drive and win-at-all-costs attitude, though the team's frequent losses, often blamed on Nobita, trigger his rage against teammates. Gian displays unshakeable confidence in his singing and cooking, both notoriously dreadful. He forces others to endure his concerts or taste his food, dismissing criticism and viewing popular idols as rivals. His singing induces nausea in listeners, though it proved an effective weapon in *Nobita's South Sea Adventure*. Confronted with recordings of his voice, he denies it sounds like him and threatens dissenters. Family profoundly shapes Gian. He exhibits intense fear of his mother, who runs a grocery store and physically punishes him for neglecting chores or bullying; even her voice sends him fleeing. Conversely, he fiercely protects and supports his younger sister, Jaiko, championing her comic book writing and sometimes using Doraemon's gadgets to aid her, though his methods often annoy her. Any comment Nobita makes about Jaiko, positive or negative, provokes Gian's aggression. He cares for the family dog, Muku, though he rarely tends to it and masks his affection with dismissive remarks. His peer relationships are multifaceted. Gian and Suneo maintain a close but unequal alliance, with Suneo often acting as his sidekick or messenger; yet Gian sometimes turns on Suneo, beating him or consuming his food during study sessions, prompting occasional gadget-fueled retaliation. Gian treats Shizuka Minamoto differently, refraining from direct bullying, showing relative respect, and halting aggression at her intervention, though he still pressures her into attending concerts or tasting his cooking. Gian's dynamic with Nobita Nobi is core to the narrative. He frequently targets Nobita for abuse over trivial or invented reasons, stating that bullying him is essential to his daily well-being. He confiscates Nobita's belongings or Doraemon's gadgets to torment or enslave him. Despite this antagonism, moments reveal Gian's underlying care and loyalty: he has saved Nobita from fatal falls or drowning, shown concern during his illnesses, offered medicine or help, and collaborated with him against Suneo or on group adventures. In *Truthful Robot*, Gian expressed a hidden desire to be friends with Nobita, echoed by their robots. Gian occasionally engages in self-reflection, particularly about his unpopularity or actions' consequences. Following Doraemon's critiques, he has attempted self-improvement, though these efforts usually collapse due to provocations or his own temper. Future portrayals show him maturing into a responsible father. Broader adventures, especially in feature films, often highlight his bravery and willingness to defend friends during true crises, contrasting Suneo's occasional cowardice. He has participated in rescuing animals or stopping unethical acts, like harming rabbits or tanukis, sometimes only after Doraemon's intervention. His catchphrase, "What's yours is mine and what's mine is mine," captures his entitled worldview. The name "Gian" functions as a pun on "giant," reflecting his physical stature and dominant group presence.
