This character was for some dumb idea I had for a comic

Basically, she was raised by rats for her entire life, only in recent years joining human civilization. Growing up living in underground filth, she learned many abilities. Her most powerful being the ability to communicate with and command rats. She also is a skilled climber, has night vision, and is immune to every modern disease. She decided to become a superhero, not really because she wants to save people, but because she was inspired by other superheroes, and she thinks thinks this is what humans like. Being raised by rats has given her unique views on the world. She views all life (including her own) as cheap. She's gotten so used to seeing close ones die, since they were all rats, that death is a pretty nonchalant thing for her. Her story in the comic would pretty much be about the value of life or whatever.
