Dennis Dunphy was born in Lincoln, Nebraska. Dennis becomes an aspiring athlete who receives the strength augmentation treatments offered by Power Broker, Inc. Finding himself too strong now for normal sports, he becomes a professional wrestler and member of the Unlimited Class Wrestling Federation (UCWF) along with other superheroes and supervillains such as the Beyonder, the Thing, and Screaming Mimi. He refuses to throw a fight with the Thing, and is defeated. The Puppet Master later mentally compels him to attack the Thing. Dunphy refuses the Power Broker's order to help kill Ms. Marvel. He reveals his addiction to the Power Broker's drug to the Thing, and goes through a painful withdrawal when the Power Broker cuts off his drug supply.
