Hellboy possesses superhuman strength and is able to lift up 10 tons. He posesses an accelerated healing factor, surviving injuries a normal human would find fatal. He is said to have eyesight better than that of a regular human as well. In the movies, he is depicted as being fireproof, but in the comics he can still burn; however his accelerated healing may still give off the illusion of being immune to fire.Hellboy's superhuman abilities would seem to stem from his demonic nature. While his specific powers and abilities have never been explicitly listed, Hellboy is much stronger and more physically durable than an ordinary human being.
He can be burned and damaged like any living thing, but he is possesses a "healing factor" (much like the Marvel Comics character Wolverine) that allows him to recover from wounds at an incredible rate. Hellboy has been noted to be able to see farther than the average human, and quickly heal from fatal wounds. One example of this was when he once took a sword thrust through his chest. He also has the innate ability to comprehend ancient and magical languages.
He has been savagely beaten by large monsters on several occasions and survived, often with relatively minor injuries. On one occasion, Hellboy directly charged an MG-42 machine gun and took numerous bullets to the chest before destroying the gun. The extent of Hellboy's strength is unclear, but he has, for example, torn down a large tree and hurled it at an opponent. He has also thrown opponents weighing at least four to five hundred pounds.
Hellboy also seems to age differently from normal Humans. At the time that young Hellboy tried his favorite food, “pamcakes” for the first time, he was technically two years old but appeared to be far older, around age six. In 1954 he already appeared to be a full grown adult, but was in reality about ten years old. His rapid physical maturation is in contrast to his physical rate of aging, which seems to be much slower than normal. Throughout the sixty year span of his life, Hellboy seems to have ceased to age ever since reaching physical maturity.
In addition to his natural gifts, Hellboy carries a variety of items, such as holy relics, horseshoes, and herbs in his utility belt, as well as a variety of grenades and other demolition tools; these often come in handy when fighting supernatural beasts. He also typically carries a sidearm of some sort. Originally this sidearm was a gun that was given to him by the Torch of Liberty, a World War II era superhero who also trained Hellboy in marksmanship. Unfortunately this gun was lost in the ocean during "The Third Wish."
In the Hellboy movie franchise, Hellboy also has a natural immunity to fire, though not to heated substances. It has never been firmly established if he also has this power in the comics. The film version of the character also carries an oversized pistol, known as the “Samaritan”, which Hellboy himself decribes as using “Really big bullets.” These specially-prepared bullets are hollow, and contain silver shavings, holy water, cloves, etc. to ensure the weapon's effectiveness against supernatural creatures. The gun was fashioned from melted-down church bells and fragments of the True Cross.
It should be noted though that Hellboy is, by his own admission, a lousy shot; he prefers to “mix it up” in hand-to-hand combat whenever possible.
Hellboy possesses Class 10 strength.
