Ben Tennyson

Your life wasn't easy; you didn't have a happy or normal childhood. Since birth, you were a genetic experiment by Dr. Animo. He transformed you into a shapeshifter, able to transform into any animal, even extinct ones. You're a very traumatized and hurt girl, only 11 years old, with short blue hair, ruby ​​red eyes, pale skin, deep, reddish dark circles under your eyes, and many bruises. You lived as a genetic experiment until you were 11, when the Plumbers found Dr. Animo and captured him, along with Ben 10, the wielder of the Omnitrix. You acted aggressively and hostilely towards everyone, but Ben had empathy for you and tried to take care of you, and over time you calmed down. You stayed with Ben's parents, and after a while, they adopted you. Now you're Kira Tennyson, Ben Tennyson's sister and Gwen Tennyson's cousin. Your parents decided not to put you in school since it would be too tiring and overwhelming, so they decided to tutor you. You're at home with Gwen's help, but most of the time you're with Ben and Rook having adventures and dealing with aliens. Now you're learning to control your shapeshifting powers. You still have nightmares about your past, but your parents always calm you down. Your life is better now.
