Takeshi Goda, commonly known as Gian, is a central character and neighborhood bully with a complex personality. He possesses a large build, black hair, and tan skin, creating an imposing presence. Gian frequently dominates other children through force, particularly targeting Nobita Nobi, often stealing toys or gadgets under the pretext of borrowing. Despite his aggression, he displays occasional loyalty, fiercely protecting his younger sister, Jaiko, sometimes to her annoyance. His mother, who runs a local grocery store, is the only figure he fears; she often punishes him for shirking responsibilities or bullying others. Gian exhibits overconfidence in his poor singing and cooking skills, subjecting others to involuntary concerts or meals, unaware of the negative reception. He founded and captains the baseball team "The Giants," though its performance suffers due to members like Nobita and Suneo. Losses frequently trigger Gian's abusive behavior toward teammates, reflecting his belief that winning is paramount. His relationship with Suneo Honekawa is ambivalent; Suneo acts as his sidekick, yet Gian sometimes bullies him, leading to occasional betrayals. Gian also demonstrates cruelty toward animals, though interventions by Doraemon or others often prevent harm. In *Stand By Me Doraemon*, Gian's role as an antagonist is prominent. He bullies Nobita alongside Suneo, contributing to the bleak future Doraemon aims to alter. His aggression culminates in a pivotal scene where Nobita confronts him in a physical fight to prove independence. Despite severely beating Nobita, Gian eventually forfeits due to Nobita's unwavering resolve, revealing Gian's reluctant respect for perseverance. Later, during an April Fools' prank, Gian tricks Nobita into believing Doraemon returned, inciting Nobita's use of a "lie reversal" potion for retribution. The potion causes Gian to be dragged away by his mother for punishment, highlighting his vulnerability to her authority. Beneath his antagonism, Gian shows sporadic care for Nobita. In mountain rescue sequences, he assists Nobita during perilous situations, and offers aid during illness or distress. These actions, inconsistent with his typical behavior, reveal an underlying loyalty. His character development includes attempts at self-improvement, such as reflecting on his unpopularity after friends avoid his birthday. After Doraemon lectures him on his behavior, Gian resolves to change, though mockery from Suneo often triggers relapses into aggression, illustrating his struggle between innate temper and a desire for acceptance. Gian's future portrayal suggests growth; he matures into a responsible father, indicating eventual overcoming of childhood flaws. His relationships remain integral to the narrative, balancing comedic antagonism with deeper themes of friendship and redemption.
