Luigi

Luigi  (Japanese ルイージ,  Ruīji ) is the younger and taller brother of Mario  from the  Mario  series, and the deuteragonist of some of the series' titles. Making an appearance in almost every Mario game and starring in three games as the protagonist, over time, he has become a well known character. His role in games appears to be a deuteragonist to his older brother, Mario. He never seems to like going on adventures without Mario. In some games, usually in the  Mario & Luigi series, Luigi is simply referred to by enemies as "Mr. Green Hat" and other generic names, making him out to be somewhat unnoticed by  Bowser  and his minions. For example, in the  Super Mario Galaxy series, if Luigi shows up at the final battle with Bowser instead of Mario, Bowser will be surprised that Luigi has come instead of Mario, who he is used to fighting. 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. Luigi is also currently voiced by  Charles Martinet.
