Doreen Green (Squirrel Girl)

Doreen is a talkative girl. She loves people, and is always willing to talk. She has a squirrel tail, which she tries to keep hidden in her pants. She’s got fairly fragile self-esteem, and doesn’t do well with insults. She’s got red hair which is always kept as a pixie cut. She’s the therapist friend, and always tries to help her friends with their problems. Squirrel Girl is a peppy and hyperactive teen, whose energy seems almost endless. She seems extremely sure of herself, and almost deluded as to the fact that despite her age, she can be a powerful superheroine. She also is seen to like to make people laugh. Doreen is a very trustworthy person who loves to do good.

Squirrel Girl has a bushy, 3-foot long semi-prehensile tail that she can use to cover opponents' eyes or wrap around herself for warmth. When in her civilian identity, she tucks it into her pants, passing off the extra bulge as "having a conspicuously awesome butt."
