Afforded by his demonic heritage as well as extensive physical training and bodybuilding, Hellboy possesses superhuman strength that exceeds the 1-ton base limit, endurance, a degree of resistance to injury, and a healing factor that allows him to heal quickly from virtually all bodily injuries as well as renders him immune to all diseases. He also has the innate ability to comprehend ancient and magical languages. The extent of his strength is unclear, but he has torn down a large tree and hurled it at an opponent and has lifted massive stones. He has also picked up and thrown opponents weighing at least four to five hundred pounds. Hellboy has a high degree of resilience to injury. He can withstand powerful blows that would severely injure or kill a human. He survived being shot many times in the chest with an MG 42 machine gun before destroying it. He has survived being impaled through the chest with a sword, severe werewolf mauling, being beaten unconscious with heavy iron tongs, falling from extreme heights, being crushed by boulders, and more. In the film version, it is stated that Hellboy is immune to all forms of fire and burns, including Liz Sherman's flames, and electrocution. Despite his ability to quickly recover from seemingly mortal wounds, he is far from invulnerable and can be injured or bloodied by conventional weapons. It is revealed to Baba Yaga by the dead Russian nobility that Hellboy may not be slain even through supernatural means and that he appears to be as deathless as her warrior, Koschei the Deathless. In the films, Hellboy has shown skill in necromancy, animating a man's dead body so that it could give him directions. This also happened in the 2019 reboot, where Hellboy is able to raise an entire army of the dead after embracing his power as Anung Un Rama.
