Carn Dillon or Misteria

This is my oc from teen titans, carn dillon.
He is raven's love when beast boy just get's too immature for her. He is a superhuman and his super name is Misteria because he doesn't know how he got his powers or where he's from. His powers are the ability to control anything or turn into anything. But it hurts him to do big things. Like it's hard for him to control humans but easy for him to control say mice.
