Squirrel Girl (Doreen Allene Green) is a superheroine appearing in American comic books published by Marvel Comics. Created by writer Will Murray and writer/artist Steve Ditko, she first appeared in Marvel Super-Heroes vol. 2 #8, a.k.a. Marvel Super-Heroes Winter Special (cover-dated Winter 1991). Murray created the character out of a desire to write lighthearted stories, in contrast to the heavily dramatic tales that were then norm in mainstream comics. Although distinct from Marvel's mutants, Doreen has a genetic anomaly which gives her the ability to communicate with squirrels. She has been a member of both the Avengers and the Great Lakes Avengers, and has been a supporting character in stories featuring Luke Cage and Jessica Jones. Doreen has also appeared in her own solo series, which have depicted her dividing her time between her superhero adventures and her work as a college student.

Later, she was slated to join the New Warriors, but writer Fabian Nicieza left Marvel before going through with his plan. In 1997, Fleer-Skybox released cards based on Marvel Superheroes, one of which was a more sexualized version of Squirrel Girl. She did not appear again for nearly a decade. She was mentioned only once in comics during that time: In Deadpool #7, Deadpool's friend/maid/mother-figure/prisoner Blind Al mentions accidentally putting "bleach in with [Deadpool's] Squirrel Girl Underoos." In 2005, comic writer Dan Slott wrote a four-issue miniseries for the superhero team the Great Lakes Avengers. Created in 1989, this team was made up of enthusiastic heroes with bizarre and nearly useless abilities. They had appeared only a handful of times over their 16-year history, serving as comic relief.
