Gumball Watterson

Zach "Gumball" Tristopher Watterson is the main character of The Amazing World of Gumball. He is a twelve-year-old, light blue male cat that goes to Elmore Junior High with his ten-year-old adopted brother/best friend Darwin and his four-year-old sister Anais. Gumball is in Miss Simian's class. Gumball also has a crush on Penny, and though their feelings are mutual, they struggle to express their emotions to each other.

Early Concept
Originally, Gumball was to be a blue dog. Not much thought was put into this choice - it was more of a placeholder than a final design. As the creators developed the character further, they decided to make him a black cat as it fit the personality they had in mind for him: unlucky, but optimistic (black cats symbolize bad luck). The creators found this trait to be too restricting in terms of possible plots and stories. In addition, a silhouette cat would be "hard to read" on the backgrounds planned for the show. Finally, the decision was to make him blue, a decision that Bocquelet liked because blue isn't a color usually found on cats, and it had a "70's-80's Japanese mascot" sort of feel.
