Gian, known fully as Takeshi Gouda, is a central figure in the Doraemon franchise. Around 10-11 years old, he attends the same school as Nobita Nobi. Physically imposing and remarkably strong, Gian possesses capabilities classified as Wall Level; he can harm characters who endure significant impacts and lift heavy objects like a full cart of rocks or a large pot of oil, though it requires effort. His appearance features black hair, tan skin, and outfits varying by adaptation, such as an orange shirt with a light red stripe and brown pants in the 2005 anime. Gian's personality is aggressively domineering. He frequently bullies other children, especially Nobita, often confiscating toys, manga, or Doraemon's gadgets under the guise of "borrowing," epitomized by his catchphrase: "What's yours is mine, and what's mine is mine." Despite this entitlement, he shows fierce loyalty and protectiveness towards his younger sister, Jaiko, aiding her comic writing efforts even when his methods annoy her. He harbors an intense fear of his physically punishing mother, who disciplines him for misbehavior. Gian is notoriously afflicted by two oblivious flaws: an atrocious singing voice capable of causing physical damage like cracking buildings or triggering explosions, and terrible cooking skills, both frequently sparking chaos. His relationships are complex; while he bullies Nobita and Suneo, he relies on their companionship and teamwork. Suneo often acts as his sidekick, though Gian's aggression strains their bond. In critical moments, Gian reveals genuine care, such as rescuing Nobita from danger or supporting him during illness. In *Nobita's Art World Tales*, Gian's characteristic impulsiveness leads him and Suneo to re-enter a painting world unsupervised, resulting in their arrest for alleged art theft and necessitating rescue by Shizuka and Claire. During the film's climax, the antagonist Isere turns Gian to stone; he is later restored and joins the collective effort to save the kingdom. A parallel universe version of Gian exists, presenting a stark contrast: timid, possessing a beautiful singing voice, and entirely lacking aggression.
