Powers: The Hulk possesses an incredible level of superhuman physical ability. His capacity for physical strength is potentially limitless due to the fact that the Hulk's strength increases proportionally with his level of great emotional stress, anger in particular. The Hulk uses his super-humanly strong leg muscles to leap great distances. The Hulk has been known to cover hundreds of miles in a single bound and once leaped almost into orbit around the Earth. The Hulk has shown a high resistance to physical damage nearly regardless of the cause, and has also shown resistance to extreme temperatures, poisons, and diseases in addition to regeneration of damaged or destroyed areas of tissue at an amazing rate.
The Hulk's body also has a gland that makes an "oxygenated per fluorocarbon emulsion", which creates pressure in the Hulk's lungs and effectively lets him breathe underwater and move quickly between varying depths without concerns about decompression or nitrogen narcosis.
