Mario's younger brother, Luigi, is a cowardly guy who is afraid of basically everything. But that doesn't stop him from being a hero when he needs to be. His biggest goal in life is to be just like Mario.

Same deal with Mario, if you don't know the voice, this role isn't for you.

DUE WARNING, Luigi doesn't have any proper speaking roles so pretty much every line you get will be improvised based on what is happening in the scene.
