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.
How does he look like?EditGumball is a light blue cat. On his oversized head, he has six whiskers but most of the time only five are visible because his head is always shown at an angle. He usually wears grey trousers coupled with a tan sweater which with brown cuffs and a brown collar. Like his mother and father, Gumball doesn't wear shoes, and is the only member of the Wattersons without visible eyelashes, although in some episode he is seen with visible eyelashes, like in The Refund.
In season 2, his design changes slightly. His head and his whiskers are bigger, his tooth is gone, and his eyes are rounder. Also, his voice started getting deeper.
Gumball is portrayed as a fun-loving, imaginative, rather optimistic, and a very mischievous cat. When his mishaps get himself into a mess, he usually attempts to fix things with somewhat dimwitted ideas, which usually get him into even more trouble than before. No matter how his schemes resolve themselves, Gumball's naivete stops him from learning his lesson. He usually plans his mishaps with Darwin. Like Darwin, Gumball does not appear to notice deception, which may mean that he is too optimistic to notice most negative things around him.
Gumball has a big ego and it is where he is most sensitive. Otherwise he is usually positive on all matters concerning him. Gumball is smart, but that doesn't mean he's wise. At times he acts really stupid and goes to great illogical lengths to find something, but he has shown some degree of cleverness in other circumstances. He happens to have a superior vocabulary than that of most of his classmates, using more mature words. Gumball has also displayed extents of observancy and operational ingenuity-able to identify small things like the burn markings on Rocky's palms, intellectually arrange escape routes based on his surroundings, and even counter his own mother Nicole's hand-based offences for a great deal of time, shown in both episodes The Date and The Remote; in which case even secretly confiscating her car keys from her pocket in the process. His antics have gotten him in dangerous and often life-threatening situations, usually saved by luck someone more sensible at the time. He has shown skill in building, when he made a system of chain reactions to launch a bowling ball onto the moon, as seen on The Car, though he failed miserably in the last element.
