Demolition Man

Courtesy from Wikipedia:

Augmentation of Dennis Dunphy's physical attributes by Dr. Karl Malus on behalf of the Power Broker increased his physical strength, stamina and durability to superhuman levels. Dunphy possesses superhuman strength sufficient to enable him to lift at least 15 tons. He was addicted to a drug supplied by the Power Broker based on a lie that it was needed to stabilize his augmentation, but was used to keep him dependent on Power Broker.

He has a heart condition, increasing his vulnerability to excessive exertion.

Dennis is a skilled aircraft pilot. He is also an excellent hand-to-hand combatant, especially in wrestling, and received further training from Captain America.
