Simon "Fireball" Brad Watterson (usually referred to as simply Fireball) is the eldest son of Richard(?) and Nicole Watterson. Fireball is a blue cat, with a look similar to Gumball. However, unlike Gumball, all of his whiskers are visible.

Original concept

In Fireball's early design, his pants were brown and his skin tone was supposed to be a more darker shade blue. His original name was supposed to be Tony.


He wears a red and black striped sweater, green pants, and, like Gumball, Nicole, and Richard, he doesn't wear shoes.


Fireball is the most intellegent person in the house. He is very mature and gentle most of the time, but in reality he is a very stressed person because he always sits up late to make Gumball's homework because Gumball is too lazy to do it.

Fireball is also a kind of a hero. He has helped Anais down from one of the upside tables in The Fireball Adventure. He also saved Gumball from drowning by removing the plate he layed under underwater. Later when they all got up Aguilera reminded him that he had saved six people's lives. He also saved Anais from a eagle in Underneath my skin theres an Eagle.

Fireball has also shown a softer side, like bursting into tears when Gumball was took away from him in Selling Out

It also shown that Fireball can be a very caring and comforting person. In We came for you, when Darwin was taken away by his "parents", he comforted Gumball by reminding him that he still got Fireball as a friend.

It's also shown that Fireball is a good journalist. In The End of the world, he was shocked by the end.
