Luigi (Japanese: ルイージ, Ruīji) is Mario's younger, taller twin brother and is a major protagonist in the Mario Franchise. Throughout his life, he has lived in Mario's shadow, developing both cowardly and heroic tendencies. He was originally a palette swap of Mario, just for a 2-Player option. Since the multiplayer option was dropped from most main Super Mario games, beginning with Super Mario Land, Luigi has gained his own identity and personality. This is noticeable in the Luigi's Mansion series and the Mario and Luigi series.
