Heatblast is a magma-based lifeform whose body is composed of brown and red rocks with lava inside. His head is completely fiery. His body is extremely hot, making touching him very damaging without protection. His feet have slight oval like design with only two toes and one back toe. Heatblast wears the Omnitrix/Ultimatrix symbol on his chest.
While under the influence of a cold, Heatblast's fire and lava turn blue and replaces his pyrokinetic powers with cryokinetic powers.
In Ultimate Alien, Heatblast's appearance is slightly altered. His eyes are no longer connected to the fire on his head. His rocks are darker. His rock pattern over his body is different, and seems to have slightly fewer rocks, revealing more of the lava inside Heatblast. His voice sounds like Jetray's, except it's deeper.
Gwen as Heatblast hardly looks any different, her chest was bigger and her voice was more feminine. She wore the Omnitrix symbol on her chest.
In The Forge of Creation, 10-year-old Heatblast's eyes are not connected to the fire on his head for an unknown reason.
Heatblast has the ability to generate, manipulate and project intense heat and fire from his body. He can shape that fire into fireballs, fire breath, flaming discs and fire tornadoes. He can also use fire in defensive maneuvers such as making a wall out of fire.He can use fire as a close range weapon as he can generate it around his hands and punch his enemy.
By propelling himself like a rocket or surfing on a fire board, Heatblast is able to fly.
In Protector of Earth, Heatblast can wield flaming fists, shoot a beam of fire, fire rapid sparks, throw fire crescents, create fire tornadoes, breathe fire like a dragon, ride on a fire surf board, make a large melt down and shoot fire meteors.
In Viktor: The Spoils, Heatblast blasted fire that was so hot, it melted a tank. He also blasted hot fire in Secrets, so that it melted the road and almost buried Vilgax in hot tar.
In Side Effects, Heatblast with a cold is seemingly made of icy fire instead of normal fire. And his pyrokinesis becomes cryokinesis.
According to Dwayne, Heatblast is capable of making his flames explosive, something Swampfire is not capable of doing unless his flame hits something flammable.
Weaknesses
When Heatblast is exposed to enough water or fire extinguishing substance, his fire is extinguished, and must wait until he is hot again to use his fire abilities.
