Takeshi Goda, known as Gian, appears in "Doraemon: Nobita's the Night Before a Wedding" during Nobita's bachelor party, which he hosts at his home. His characteristic enthusiasm for gatherings centered on his interests shines through. At the party, Gian insists on performing his original song "Gian Samba Part 2" for the attendees, reflecting his notorious overconfidence in musical abilities despite causing others discomfort. His forceful personality emerges as he pressures the visibly reluctant Nobita, Suneo, and Dekisugi to join the festivities, aligning with his established pattern of dominating social situations through an imposing physical presence and loud demeanor. Gian's personality blends aggression with underlying loyalty. He frequently bullies Nobita and others, seizing their possessions under the pretext of "borrowing" and reacting with short-tempered anger to criticism. His singing voice and cooking skills remain objectively poor, yet he retains absolute conviction in his talents, often subjecting friends to involuntary concerts or meals. Despite these antagonistic traits, Gian displays genuine care during significant moments. He offers sincere congratulations to Nobita about the wedding and participates in collective celebrations, indicating his capacity for camaraderie. This duality appears throughout the broader series, where he often supports friends in genuine crises despite routine bullying. His relationships reflect his broader characterization. Gian interacts with Nobita in a domineering yet paradoxically dependent manner, coercing him into activities while simultaneously valuing their connection. With Suneo, Gian alternates between camaraderie and intimidation, reflecting a power imbalance where Suneo acts as an unwilling sidekick. Gian shows consistent respect toward Shizuka, refraining from directly bullying her due to her gender, though he remains oblivious to her discomfort with his behavior. His familial bonds are significant; he exhibits deep protectiveness toward his younger sister Jaiko and profound fear of his mother, who disciplines his aggressive tendencies. Gian's background across the franchise establishes his role as a neighborhood bully with a fixed routine. He captains the local baseball team "The Giants," forcing Nobita to participate despite blaming him for losses. His household runs a grocery store, and his mother frequently punishes him for neglecting chores or mistreating others. Character development occurs sporadically; realizing his unpopularity during a poorly attended birthday party leads to temporary attempts at self-improvement before reverting to established patterns. Films and specials occasionally emphasize redeeming qualities, such as bravery during group adventures or emotional vulnerability regarding Jaiko's wellbeing. These elements collectively form a multifaceted character whose aggression coexists with loyalty and occasional introspection.
