Luigi is Mario's younger but taller twin brother, the secondary protagonist of the Super Mario franchise, and the main protagonist of the Luigi's Mansion series.
Luigi first appeared in Mario Bros., a 1983 platform game, in which he was originally designed as a palette swap of Mario with a green color scheme; Luigi has since appeared in multiple games and other media throughout the Mario franchise, in which he developed a personality and style of his own.
Throughout his life, he has lived in Mario's shadow, developing both cowardly and heroic tendencies. Despite this, Luigi has helped and fought alongside his brother on many occasions. Mario Bros. for the Game & Watch marks his first appearance, in which he is an exact copy of Mario.
Luigi is kind but can be a bit nervous, especially around ghosts. However, his abilities are on par with Mario's, so when these brothers team up, there's nothing they can't achieve.
As the multiplayer function of both Mario Bros and Super Mario Bros required the inclusion of a second playable character, Luigi entered the Super Mario franchise earlier than many remember. Although both characters initially lacked substance, later entries expanded Luigi’s role and characterization to distinguish him from his brother.
