Gian

From Doraemon Wiki

Takeshi Goda (Japanese Kanji: 剛田武), more commonly known by his nickname Gian (Japanese: ジャイアン, translation of the English term Giant), is one of the main characters in the Doraemon series.

He is recognized by his large build (might partly be contributed by obesity), as well as mean, selfish and violent manner. He "rules" the neighborhood with force, often to the physical expense of other children, especially Nobita, who often resorts to asking Doraemon for gadgets to get even on him. In addition, he has a tendency to rob things from other children, usually Suneo, who offers himself to be Gian's sidekick in most occasions.

Gian is probably the most athletically talented among the kids, and he's also the captain of the local baseball team -- The Giants. Because of the poor skills of some members like Suneo or, more significantly, Nobita, the team often found itself at the bottom of the league table. Defeats often lead to Gian's abuse of his teammates.

Another prominent hobby of Gian is singing, in which he thinks himself proficient, but actually very appalling, to the point that people often pass out upon hearing his singings. Nonetheless, he manages to "convince" the neighborhood to be his concert audience, and even force them into praising his singing.

Apart from his father and mother (whom he fears the most), Gian also has a younger sister called Jaiko. He is extremely protective of Jaiko, sometimes to her annoyance.
