Among Hellboy's more obvious powers are superhuman strength and resilience in the face of physical injury. He can withstand powerful blows that would severely injure or kill a human. In "The Lost Army", he rapidly heals from being shot many times in the chest with an MG-42 machine gun before destroying the gun. He has also withstood being impaled through the chest with a sword, healing completely within a matter of minutes. Despite his ability to rapidly recover from seemingly mortal wounds, he is far from invulnerable, and can be injured by conventional weapons.
Hellboy also ages differently from humans. In the story Pancakes he is two years old but appears to be far older. In Nature of the Beast, set in 1954, the ten-year-old Hellboy appears fully grown. His rapid apparent maturation is in contrast to his actual rate of aging, which seems to be much slower than humans. Throughout the sixty-year span of the comics, he has not aged beyond the point at which he reached physical maturity.
In addition to his natural physical abilities, Hellboy carries a variety of items in his utility belt that can be used against various supernatural forces. He has been known to carry holy relics, horseshoes, various herbs, and grenades. Though he commonly carries an oversized revolver, Hellboy freely admits to being a lousy shot and often fights hand-to-hand.
Hellboy's right hand, referred to as the "Right Hand of Doom", consists of a large forearm and hand that seems to be made from red stone. The Hand is dexterous enough to catch a fly, but its large size causes Hellboy to prefer his normal-sized left hand to operate weapons and devices. The Hand is effectively invulnerable and feels no pain, serving much like a sledgehammer when used to punch an enemy.

Iceman possesses the power to radically decrease the temperature of ambient water vapor in his immediate environment, thereby freezing it into ice. In this manner he is able to quickly form a great variety of ice structures, including projectiles, shields, ladders, baseball bats, etc. He often makes ice slides which form rapidly beneath and behind his feet, moving him along the slick surface at high speeds. Originally, Iceman's own body temperature would lower dramatically when his powers were active, reaching −105 °F (−76 °C) within a few tenths of a second (now his body usually converts to organic ice; see below). Iceman is immune to sub-zero temperatures; he is also able to perceive the thermal energy level of objects around him. Because cold is the absence of heat, Iceman does not actually 'emanate' cold; rather, he decreases thermal energy. As mentioned by writer Mike Carey, Iceman is "an Omega level mutant...[and] has powers that can influence the ecosystem of the entire world."
In his early appearances, Iceman generally covered his body in a thick layer of what appeared to be snow; hence he looked more like a traditional snowman than an ice-man. Upon further training in the use of his powers, he was able to fashion an armor of solid ice around his body when using his powers, which afforded him some degree of protection against concussive force and projectiles. Later on, he manifested the ability to convert the tissue of his body into organic ice. He sometimes augments his organic ice form with razor sharp adornments to his shoulders, elbows, knees, and fists. Iceman has also been able to move rapidly to another distant location while in his organic ice form, being able to deposit his bodily mass into a river and reconstitute his entire mass a great distance away in a matter of minutes (by temporarily merging his molecules with those of the river). On one occasion, Iceman suffered a severe chest injury while in his ice form and was able to heal himself by converting back into his normal human form.
Iceman is also able to reconstitute his organic ice form if any part of it is damaged, or even if it is completely shattered, without permanently harming himself. He can temporarily add the mass of a body of water to his own, increasing his mass, size, and strength. He can survive not only as ice, but as liquid water and water vapor. He can also transform his body from a gaseous state back to a solid, although it is physically and mentally taxing. Iceman can also freeze sea water, as seen during the "Operation Zero Tolerance" story arc.
Iceman's powers were pushed to their limit while possessed by Emma Frost, who used Iceman to discover the fate of her Hellions. During this time Iceman was able to control all forms of moisture, freeze fluids inside people's bodies, travel as a liquid, solid or gas. Not even the combined might of the X-Men Gold team was able to stop Emma Frost in Iceman's body. Following this Bobby confronted Emma about how she was able to use his powers so effectively. She then begins to spend time training with him
