After Doctor Sivana's alliance with Black Adam fails, he heads to the Rock of Eternity where he can't get in because of a magical shield. He cries out for someone to help him save his family saying that while science has failed them, magic could save them. A voice is then heard saying it is indeed possible. The voice also says it has been watching him with the magic eating away his body but not his mind. Doctor Sivana asks for the voice's name and discovers a caterpillar-like creature trapped in a bottle. The creature claims that people call him Mister Mind and makes note that he and Doctor Sivana shall be the "best of friends." Introduced as a well-built man of average height, using his magic-seeing eye causes Doctor Sivana to slowly wither to a form resembling his stooped, traditional Fawcett appearance.
