In the spring of 1928, Disney asked Ub Iwerks to start drawing up new character ideas. Iwerks tried sketches of various animals, such as dogs and cats, but none of these appealed to Disney. A female cow and male horse were also rejected. They would later turn up as Clarabelle Cow and Horace Horsecollar. A male frog was also rejected. It would later show up in Iwerks' own Flip the Frog series. Walt Disney got the inspiration for Mickey Mouse from a tame mouse at his desk at Laugh - O - Gram Studio in Kansas City, Missouri. In 1925, Hugh Harman drew some sketches of mice around a photograph of Walt Disney. These inspired Ub Iwerks to create a new mouse character for Disney. ``Mortimer Mouse ''had been Disney's original name for the character before his wife, Lillian, convinced him to change it, and ultimately Mickey Mouse came to be. The actor Mickey Rooney claimed that, during his Mickey McGuire days, he met cartoonist Walt Disney at the Warner Brothers studio, and that Disney was inspired to name Mickey Mouse after him. This claim, however, has been debunked by Disney historian Jim Korkis, since at the time of Mickey Mouse's development, Disney Studios had been located on Hyperion Avenue for several years, and Walt Disney never kept an office or other working space at Warner Brothers, having no professional relationship with Warner Brothers, as the Alice Comedies and Oswald cartoons were distributed by Universal.

Mickey generally appears alongside his girlfriend Minnie Mouse, his pet dog Pluto, his friends Donald Duck and Goofy, and his nemesis Pete, among others (see Mickey Mouse universe). Though originally characterized as a cheeky lovable rogue, Mickey was rebranded over time as a nice guy, usually seen as an honest and bodacious hero. In 2009, Disney began to rebrand the character again by putting less emphasis on his friendly, well-meaning persona and reintroducing the more menacing and stubborn sides of his personality, beginning with the video game "Epic Mickey".
