Fez

"Who are you, anyways?"

"Wait a minute... I'm Friday's imaginary monkey, not yours. That means Friday's with Ralph right now. Oh... RALPH, IT HAPPENED AGAIN!"

- Homer meets Fez

Fez is an imaginary ahool (a winged monkey-like creature) that is arguably Friday's conscience turning itself into a new form to get him to do more good things. Fez first appeared in the episode "Into Imagination Land" and has, since then, been a major character in the series.

Personality
Fez is a nice, happy creature. He is constantly seen trying to convince Friday to do good. Sometimes if Fez is really angry or frustrated he will insult or yell at people.

Non-Canon
Fez has appeared in countless Curse of the Skull specials. In an episode taking place in the future, it is shown that Fez becomes angrier, and more like a gorilla then a monkey.
