Gumball Watterson

Gumball (formerly Zach) Tristopher Watterson (voiced by Logan Grove on seasons 1-3, Jacob Hopkins on seasons 3-5, and Nicolas Cantu in season five onwards) is the protagonist of the series. He is a 12-year-old[4] mostly mischievous light blue cat who lives with his family in the fictional California city of Elmore. He attends Elmore Junior High in the seventh grade with his adoptive best friend Darwin, who is 10 years old.[5] Often finding himself and Darwin in various antics which end up getting them into trouble, episodes in the series' first season characterized Gumball as well-meaning in his actions, but with naive tendencies; throughout the show's progression, he has since established himself as a more serious character capable of logical thinking and prone to sarcasm. In "The Name", it was discovered that his real name was "Zach", however, this caused him to develop a split personality, though he was seemingly cured at the end of the episode, by changing his name to Gumball.
