Powers: Initially, Brainstorm may have had some degree of superhuman strength, or he may have just fought with a madman's rage. When sent into conflicts, he believed himself to be dreaming, and so had no compunctions about acting out his rage and violent emotions. His insanity allowed him to shrug off most forms of injury that did not utterly incapacitate him.
Later, he took on a more reptilian appearance, possessed superhuman strength (Class 10?) and durability. He possessed a "3rd eye" in his mind, through which he was constantly bombarded with visions of false pasts and alternate futures. In addition, he could project those images into the minds of others, or cause others to suffer hallucinations based on their own fears and paranoias.
