Mario's brother who's also a scary cat! his greatest fear is ghosts! but he has the poltergeist (a vacuum to suck up ghosts) which can suck up any ghost and it comes with a flashlight to blind opponents or stun ghosts! Luigi can also summon gooigi who is made of a Green Jello so he can fit through vents or bars!
