Principal Nigel Brown is a supporting character in The Amazing World of Gumball. He is the principal of Elmore Junior High. Because he is madly in love with Miss Simian, he's not very responsible when it comes to running the school, and doesn't seem to care about the well being of the students that much.
Principal Brown is a slug with a thick coat of brown fur that covers his entire body, except for his eyes. In "The Mystery", some of Principal Brown's fur was burnt off, revealing his tan-tinted skin. At the end of "The Mystery", he has sharp fang-like teeth, but while in the nurse's office, he has regular teeth. Principal Brown speaks in a soft-spoken tone of voice with a slight British accent.
Despite being the principal of Elmore Junior High, he is shown to have a massive crush on Gumball's teacher, Miss Simian, and they are constantly flirting, much to everyone else's dismay. Because he spends most of his time thinking about and trying to please Miss Simian, he doesn't pay much attention to the students. In addition to this, Principal Brown has also been shown to get into The Wattersons' personal business, like in "The Painting". Although in "The Genius," he didn't care at all that The Wattersons would never see their son, Darwin, again.
