Luigi (; Japanese: ルイージ, romanized: Ruīji) is a character created by Japanese video game designer Shigeru Miyamoto. Part of Nintendo's Mario franchise, he is a kind-hearted, cowardly Italian plumber, and the younger fraternal twin brother and sidekick of Mario. Like his brother, Luigi's distinctive characteristics include his large nose and mustache, overalls, green hat, and high-pitched, exaggerated Italian accent. Luigi first appeared in Mario Bros.
