Sofia Devil

Sofia, a demon who was once Trevor One's girlfriend, suffered a brutal death at his hands. Now, as a demon, she seeks revenge and to stop his plans to destroy the world. She won't allow it. (They even had a child together, and she had a son named Carlos, the scientist god.) However, she refuses to acknowledge Trevor One as his father. She is also a very kind and loving mother to her little one, and she wants him to forget that Trevor One is his father.

She sometimes has to endure leaving Trevor One alive because she doesn't want to take care of her son Carlos alone either.
