Fawful

and is an eccentric Beanish genius who is a recurring character in the Mario & Luigi series. He is notable for speaking in grammatically incorrect English and making obscure food metaphors (e.g. "And this battle shall be the delicious mustard on that bread!...The mustard of your doom!"). Fawful is a mechanical genius, but his common sense suffers due to his extreme rage which often causes him to act in a delusional manner. He is the secondary antagonist of Mario & Luigi: Superstar Saga and the main antagonist of Mario & Luigi: Bowser's Inside Story. He is an anti-hero in Mario & Luigi: Partners in Time. He's a shopkeeper and plays no role in the story aside from foreshadowing Bowser's Inside Story.
