His durability, regeneration, and endurance also increase in proportion to his temper. Hulk is resistant to injury or damage, though the degree to which varies between interpretations, but he has withstood the equivalent of solar temperatures, nuclear explosions, and planet-shattering impacts. Despite his remarkable resiliency, continuous barrages of high-caliber gunfire can hinder his movement to some degree while he can be temporarily subdued by intense attacks with chemical weapons such as anesthetic gases, although any interruption of such dosages will allow him to quickly recover. 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 for extended periods, and when injured, healing from most wounds within seconds, including, on one occasion, the complete destruction of most of his body mass. His future self, the "Maestro", was even eventually able to recover from being blown to pieces. As an effect, he has an extremely prolonged lifespan.
