Catie the demon guardian

Catie is an immensely powerful demon, perhaps one of the most powerful of all demons, no one knows how old she really is. She has unnatural strenght which no one knows what the limit to it really is. With one punch to the head she could easily crush even the thickest skull if she wanted to. According to some legend about her she is a direct descendant of the ultimate being. No one has ever seen the ultimate being before, so they dont even know what gender the ultimate one was. Legend of the Ultimate one leads some to believe that Catie herself is the ultimate being, but there is no proof to the statement.
