Gian (Takeshi Goda)

 Takeshi (born on 15 June), usually known by the nickname "Gian" (ジャイアン Jaian) from English word "Giant", is the big, strong, and quick-tempered local bully. He also frequently steals other children's toys and books under the pretext of "borrowing" them, unless the toy is damaged. This is how most fans considered Gian to be the antagonist of this show. However, he does not hesitate to help Nobita and his friends when they are in real trouble, which often occurs in full-length stories.

He is known for his confidence in his terrible singing voice, though he considers himself a great singer. But in some episodes when his voice is recorded and he hears it, denies it being his voice and threatens to beat up the person who sung his songs in a bad way. Several of the stories revolve around Nobita and his friends' efforts to avoid Gian's concerts. Gian is also confident in cooking, but just like his singing, his foods can "beat up" people very easily.

Although he bullies the other children (mostly Nobita), he is terrified of his mother, a fact Nobita and Doraemon sometimes use in their favor. He founded his own baseball team named after himself. Although Nobita is often blamed for the losses against the baseball team's rival, the "Tyranos", Gian still forces Nobita to play because they do not have enough players.
