The younger brother to Mario. He is taller and less rounded. he is shown to be scared of ghosts. He is sick and pale with grief from standing in his brothers shadow for so long, Playing the second fiddle, and easily being the second banana, He plays it well however. He has had two games were he has taken the limelight, the first in Mario is missing (somewhere along the line luigi's evil doppelganger Weegee was leaked and born into the world through the NES version of this game with the creepy version of Luigi) and Luigi's mansion, where he had to vacate a mansion he won that was haphazardly filled with ghosts, He will get a sequel to this game, named Luigi's mansion 2, which was showcased in E3 2011.
“Hey, Bro! Everyone left me behind! I had to hustle to get up here!”-Luigi, always getting left behind.
