Minerva Mouse, also known as Minnie Mouse, is one of the main characters of the Mickey Mouse franchise.
She is the female counterpart and the official as well as permanent lifelong girlfriend of Mickey Mouse. Created in 1928 by Walt Disney and Ub Iwerks, her first appearance was in a cartoon short called Plane Crazy, which was created before Steamboat Willie as a silent film, but not distributed until 1929 with sound added.
Minnie Mouse has, over the years, grown into a strong, rather complex, and easily identifiable character in the Disney universe. Her many personality traits are more than noticeable, as well as consistent, in every incarnation of the character.
