The Fly is a villain from The Simpsons: Treehouse of Horror VIII.
Homer buys a teleporter from Professor Frink's yard sale and forbids Bart from using it. At night, Santa's Little Helper and Snowball II get fuses together before Bart joins with a fly, believing it will give him superpowers. Instead, this resulted in their heads getting swapped and the family assume the fly is Bart. The next night, the fly tries to murder Lisa when Bart reveals what happened before Lisa knocks them into the teleporter. Bart then appears in the living room normal. An enraged Homer grabs an axe and starts chasing Bart around for using the teleporter.
