Colin and Felix

Colin and Felix are supporting characters in The Amazing World of Gumball, and are a duo of beige-colored eggs that made their first appearance in "The End" at Food N' Stuff.

Appearance
Colin and Felix are a pair of beige eggs. Colin has glasses and braces, while Felix is relatively bare with acne on his forehead; both have buck teeth, similar eyebrows, and a generally nerdy appearance overall. They both wear pairs of white arm gloves and black footie trousers.

Personality
Colin and Felix are the biggest geeks in Elmore Junior High. They speak with British accents, and have an obsession with academics. The two of them are relatively friendly, being sociable enough to attempt to chat with Gumball in "The Genius," and later asking him to be their club president in "The Club." However, Colin and Felix are known for harassing other people on Internet forums, as shown in "The Promise." Due to their nerdy way of talking, tendency to use sophisticated words, and their habit of harassing people on the Internet, it is likely that most people do not understand what they are saying, or refrain from talking to them, causing Colin and Felix to be social rejects.
