One of the most trusted lieutenants in the Justice Lords, Hammerlock has been a superhero for longer than most. He stopped such famous villains as Chemical Man and the Murder Master. He joined Mina's Justice Lords after they all fought beside each other in the Alien Army War.
His powers came to him by natural means; activating one hot August night while he slept. He gained the ability to flight, class 7 super strength and force blasts capable of blowing large holes in walls and easily blowing up cars.
Hammerlock took his name from the company his father tried to get off the ground before he had to file bankruptcy. He didn't become a superhero for wealth or glory. He did it because it's what his father would have wanted him to do.
