Heatblast is the Omnitrix's DNA sample of a Pyronite from the planet-like star Pyros.
Heatblast is a magma-based lifeform whose body is composed of a bright red inner magma body covered by a dark red or brown rocks. As a fire-based entity, his body radiates high amounts of heat. His feet have a slight oval-like design with only two toes and one back toe. His tongue is also made of fire. When under the effects of a cold, Heatblast's body and flames turned blue. 18-years-old Heatblast also sports two craters on his shoulders, just like his original Ben 10,000 counterpart. Just like Swampfire, Heatblast has also undergone a transformation, going from his classic bright yellow, to a bright orange with craters not lit, to his final deep red with fiery craters on the shoulders.
Powers and Abilities
Being one of Ben's most versatile alien forms, Heatblast is a pyrokinetic, meaning he has the ability to generate and manipulate intense heat and fire from his body. He can form fire into any shape that he chooses, commonly fireballs. He can also enhance the fire in his hands for flaming punches, and can breathe fire like a dragon. To top it all off, he can even absorb heat and fire at the same time. This means he can put out a fire faster than he can start one.
Heatblast's fire can become hot enough to melt a tank or a road, as he almost buried Vilgax in boiling tar when he was younger. Several years later, Heatblast was able to bury him in the ground up to his shoulders. Heatblast can make his flames explosive, explaining why his fire tended to cause explosions on a regular basis. On that note, he can even create fire uses with the snap of his fingers.
Heatblast has enhanced strength and durability, enough to hold his own with his fists against Viktor when he was 16, making the latter stumble several steps backwards. He can also survive being thrown through multiple buildings at high speed by Vilgax with no damage. Heatblast can swim and use his powers underwater, but with a very low intensity. He can even breathe underwater despite being a fire-based alien.
If exposed to enough water or fire-extinguishing substances, Heatblast's fire will be extinguished, though he can still heat up and reignite his fire in short amounts of time. Because of his fiery hands, Heatblast cannot hold anything without burning or melting it.
As mentioned above, when under the effects of a cold, Heatblast's pyrokinesis is replaced with cryokinesis (the ability to create and control cold and ice). Despite these new powers, Heatblast works completely "nonfunctional" to his fiery nature and the cold still prejudiced his health, meaning that it's still technically a "weakness", but not totally since it never exactly slowed Heatblast down (albeit taking a while to master it).
