Fawful

"I HAVE FURY!"

- Fawful Fawful is a recurring villian in the Mario & Luigi games. He appears in the first three installments and is known for his maniacal tendencies and his odd speech pattern. He is a sworn enemy of the Mario Bros. and would do anything to get his revenge.

Despite being a bit of a lunatic, Fawful is a mechanical genius, a trait which he often uses to his advantage. Notable creations of his include the Vacuum Helmet and  the Fawfulcopters, and he almost always relies on his gadgets to aid him in his battles against his foes.
