| Gumball's Brain
| Character Information
Gumball's Brain looks like a typical animated brain with big dark blue eyes, eyebrows, two thin arms and legs, and a mouth.
- Although it is Gumball's brain, Gumball was able to think without it. It also seems that Gumball is more intelligent than his own brain as he was "teaching" it how to be smart.
- Anais thought that his brain would be smaller due to Gumball being very dumb.
- He appeared to be much bigger in "The Bumpkin".
