Valerie is the girl Dave starts dating after high school
She's a Caucasian female with short red hair cut down to her shoulders. She has green eyes. And dresses casually like any other normal girl. She is apparently Dave's age, seeing as how the two are dating and have a relationship. Her most noticeable feature is that she has a hearing aid in her right ear.
Not much is known about Valerie's past, but she seems to be okay with Kick-Ass, as well as she knows the identity of Kick-Ass being Dave.
