Squirrel Girl

According to Marvel Rivals' website, Squirrel Girl is "more than just a computer science student at Empire State University (ESU). She also happens to have the powers of a squirrel AND the powers of a girl!"

Squirrel Girl was born in Los Angeles. Her parents are Dorian and Maureen Greene. After listening to squirrels chat outside her house as a child, she unexpectedly discovered that she could communicate with them.

Squirrel Girl joined the Great Lakes Avengers, a ragtag group of superheroes based in Milwaukee, Wisconsin and Detroit, Michigan. Deadpool discovered Squirrel Girl and her allies after he mistakenly thought the group was unregistered and attacked their headquarters. Squirrel Girl beat him in a fight, and the two later teamed up to fight A.I.M. agents. After defeating Grasshopper in the Skrull invasion, Squirrel Girl moved to New York.

Before college, Squirrel Girl nannied for fellow superheroes Luke Cage and Jessica Jones, caring for their daughter Danielle Cage. During this time, she lived in the Avengers mansion. After becoming a computer science major at ESU, she joined Sunspot's New Avengers. A year later, S.H.I.E.L.D. merged with Sunspot and Squirrel Girl became an official Marvel Avenger.

At ESU, Squirrel Girl is dating fellow student Tomas Lara-Perez, who also has a secret super-identity as "Chipmunk Hunk." Squirrel Girl, Chipmunk Hunk and Lara-Perez's close friend Ken Shiga (Koi Boi) often team up to fight crime.

During her college years, Loki also sent Squirrel Girl on a mission to fight the Frost Giants and she had a rivalry with Melissa Morbeck. Afterwards, Melissa Morbeck exposed her identity to the public and battled her with an army of villains in Central Park. Morbeck utilized Iron Man's suit technology as the 'Iron Ring' and fought with Doctor Doom against Squirrel Girl. Though things looked bleak, the Avengers and Galactus ended the fight and Squirrel Girl made peace with her public persona as a superhero she's happy fun and goofy
