Luigi (Japanese ルイージ, Ruīji) is the younger and taller brother of Mario from the Super Mario Bros. Series. Making an appearance in almost every Mario game and starring in two games, he has become a well known and lovable character. His role in games appears to be that of a sidekick to his older brother, Mario. He never seems to like going on adventures without Mario. In some games, usually in the Mario and Luigi RPG series, Luigi is simply referred to by enemies as "Mr. Green Hat" and other generic names, making him out to be somewhat unoticed by Bowser and his minions. Other than his color being green, he was planned to be exactly like Mario, but as his popularity grew, he developed a personality and style of his own. His jumping ability surpasses Mario's by far and he is normally depicted as cowardly and scrawny, but when he does get the courage to step up, he can be tough and overcome his fears.
