Squirrel Girl, real name Doreen Green, is a fictional mutant superheroine that appears in the Marvel Comics Universe. Her first appearance was in Marvel Super-Heroes vol. 2, #8, a.k.a. Marvel Super-Heroes Winter Special, in a story plotted and drawn by Steve Ditko and scripted by character conceptualizer Will Murray. Her ability to communicate with squirrels is surprisingly effective and has allowed her to defeat major supervillains. She was a member of the Great Lakes Avengers for much of the duration of that group, and later began serving as nanny to Danielle Cage, the daughter of Luke Cage and Jessica Jones. Squirrel Girl's creation and inspiration came from Will Murray wanting to cut loose from the serious drama of the X-Men titles and bring back the light-hearted anything-goes joy of comic books.
