Look at that pale skin. He's been living in his brother's shadow for too long.

Luigi is the second half of the Mario Bros., the other of course being his more famous twin brother, Mario.

Mario & Luigi in Mario Bros.
Originally depicted in Mario Bros. and Super Mario Bros. as just a palette swap of Mario, Luigi took a different shape several years later in Super Mario Bros. 2, where he gained his distinctive tall, slender figure in contrast to Mario's stout stature.
Luigi's big break came in 2001's Luigi's Mansion, his first and only solo title role in a videogame.
