Powers: Hammer can expand his hands and forearms to "giant" size at will. While not an extremely impressive ability it makes him a powerhouse. His body while normal size increases his density in order to withstand the strain his extraordinarily large hands place on his frame. With his hands increase in size also comes an increase in his ability to lift larger objects as well as striking with super human force.
Weaknesses: While Hammer's structural integrity increases leaving him resistant to injury from falls or blows he must still breath as well as eat.
