Luigi (ルイージ, Ruīji) is a video game character created by Nintendo's game designer Shigeru Miyamoto. He is portrayed as the younger brother of Nintendo's official mascot, Mario. Luigi first appeared in the arcade game Mario Bros., where he was featured as the main character alongside Mario. Since his debut, Luigi has appeared in many games throughout the Mario series, often accompanying Mario as the central protagonist, but at times starring as the main character of his own game, Luigi's Mansion. At times, Luigi is usually in his brother's shadow due to his some-what cowardly personality. While Luigi was originally created as a character identical to Mario except for being colored lime green instead of red, his rise in prominence throughout the Mario series lead to the adoption of a personality and style of his own. He is normally cowardly, but when he can get the courage to step up, he can be a tough guy. His voice is performed by Charles Martinet, the same actor who provides the voice for Mario, Wario, and Waluigi as well as other characters throughout the Mario franchise.
