Canon Biography
Luigi is Mario's younger brother. During the years in the Super Mario Bros series, he has become popular, even if he was always in the shadow of his brother. Luigi is very timid and cowardly, therefore he ends up becoming frightened and discouraged from fighting, much to his teammate's dismay. He is seen usually teaming up with Sonic whenever he gets his momentary bursts of courage. Shadow's angry attitude often scares him. He randomly fights the Axem Rangers X and the Koopa Bros, but when Mecha Sonic appears he becomes too scared and tries to hide while Mario drags him to the fight. He shows his brave side in Episode 7 when going to help Mario and the rest of the team who were trapped in the Minus World, only to end up surrounded by Bloopers. He could be often seen as comic relief in the series.
