Concept and creation 150px|thumb|left|This emblem appears on Luigi's hat and as a symbol for him in many game interfaces. Luigi's creation began in 1982, during the development of Donkey Kong, where Shigeru Miyamoto had created Jumpman (later known as Mario), hoping that he would be able to recast the character in a variety of roles in future games. Miyamoto was inspired by Joust to create a game with a simultaneous two-player mode, which led to his development of the game Mario Bros. where Luigi was given the role of Mario's brother as the second playable character, both Mario and Luigi were styled as Italian plumbers in Mario Bros., on the suggestion of a colleague.
