Originally, Miyamoto wanted to create a video game that used the characters Popeye, Bluto, and Olive Oyl. At the time, however, Miyamoto was unable to acquire a license to use the characters (and would not until 1982 with Popeye), so he ended up making an unnamed player character, Donkey Kong, and Lady (later known as Pauline).
Since Donkey Kong was set on a construction site, Mario was made into a carpenter. When he appeared again in Mario Bros., it was decided he should be a plumber, since a lot of the game is played in underground settings. Mario's character design, particularly his large nose, draws on western influences; once he became a plumber, Miyamoto decided to "put him in New York" and make him Italian,[10] lightheartedly attributing Mario's nationality to his mustache. Other sources have Mario's profession chosen to be carpenter in an effort to depict the character as an ordinary hard worker, and make it easier for players to identify with him. After a colleague suggested that Mario more closely resembled a plumber, Miyamoto changed Mario's profession accordingly and developed Mario Bros, featuring the character in the sewers of New York City.
Due to the graphical limitations of arcade hardware at the time, Miyamoto clothed the character in red overalls and a blue shirt to contrast against each other and the background. A red cap was added to let Miyamoto avoid drawing the character's hairstyle, forehead, and eyebrows, as well as to circumvent the issue of animating his hair as he jumped. To make him appear human onscreen despite his small size, Mario was given distinct features, prominently a large nose and a mustache, which avoided the need to draw a mouth and facial expressions on the small onscreen character.[14]
