Tobias is a main character in The Amazing World of Gumball. He is a student in Miss Simian's class at Elmore Junior High. His first appearance was in "The Family Battle".
Tobias believes that he is a heavily built jock, but in reality he isn't at all. Despite him not having a good, athletic build he is obsessed with sports and is always trying to hone his scrawny physique. He also seems to have a big ego. Like Gumball, Tobias has a crush on Penny.
