Luigi

Actual Background
Luigi is Mario's younger, taller, thinner twin brother. He is a major protagonist of the Mario series. Luigi has helped and fought alongside his brother on many occasions. Throughout his life, he has lived in Mario's shadow, developing both cowardly and heroic tendencies. Mario Bros. marks his first appearance in the Mario series and his debut in general. Originally a palette swap of Mario, Luigi was created to facilitate a second player option. Since the two-player mode was dropped from most main Super Mario games beginning with Super Mario Land, Luigi has gained his own identity and personality. This is especially noticeable in installments for the Luigi's Mansion series of games, as well as the Mario & Luigi series. Since his debut in 1983, Luigi has been constantly developing. Gameplay differences between him and Mario were first seen in Super Mario Bros.: The Lost Levels, which have been carried over into future games and have become standard for the character. After spending years as a palette swap of his brother, Luigi has consistently been given his own graphics since Super Mario Kart in 1992; the American Super Mario Bros. 2, however, is an exception to this. As aforementioned, Luigi also started earning his own personality in the post-Super Mario 64 era, starting with Paper Mario and Luigi's Mansion.

In Gamed9x's Series
Unlike the actual Luigi, this Luigi absolutely hates Mario. In fact, because of Mario, Luigi is colourblind. This is because after a game of Mario Kart when Luigi beat him, Mario jabbed in his eyes. He does like LSD, but for legitimate reasons. He uses LSD to make his cart go faster, and he doesn't actually take it, the cart does. Luigi is always the good guy, and unfortunately has to suffer by his horrible brother.
