Kat, legally known as Katherine Rosen, is an Adomopathic Alpha. She can learn things and figure out new skills at an incredible speed, possessing a perfect muscle memory. Unfortunately, her mind can't hold onto actual memories for a long time. Throughout the years, she picked up several techniques to deal with that issue, but she never found a way to actually fix it. Kat only remembers very few things about her childhood. She does not know where she comes from, or who her parents were.
