The Hulk possesses the potential for near-limitless physical strength depending directly on his emotional state, particularly his anger.His strength has been described as potentially limitless and directly proportional to his anger's level. This has been reflected in the repeated comment "The madder Hulk gets, the stronger Hulk gets."His durability, healing, and endurance also increase in relation to his temper. The Hulk is also extremely resistant to most forms of injury or damage, including physical, psychic, environmental extremes, and is immune to disease and poisons. His powerful legs allow him to leap into lower Earth orbit or across continents. He also has less commonly described powers, including abilities allowing him to "home in" to his place of origin in New Mexico, and to see and interact with astral forms. He has been shown to have both regenerative and adaptive healing abilities, including growing tissues to allow him to breathe underwater, surviving unprotected in space (yet still needing to breathe), and when injured, healing from almost any wound within seconds, including regenerating lost mass.
