Mad Heatblast is the Power Watch's DNA sample of a Pyronite from the planet-like star Pyros.
Mad 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, Mad Heatblast's body and flames turned blue. 18-years-old Mad Heatblast also sports two craters on his shoulders, just like the original Ben 10,000's. Mad Heatblast has undergone a transformation, going from his classic bright yellow, to a bright orange with craters not lit, to his final deep orange with fiery craters on the shoulders, surrounded by spiked armor plates. He also has spikes on his arms and he has bone-like rocks on his fingers.
Powers and Abilities
Being one of Ben's most versatile alien forms, Mad 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.
Mad Heatblast's fire can become hot enough to melt a tank or a road, as Heatblast 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.
Mad Heatblast has enhanced strength and durability, as Prime Heatblast had enough to hold his own with his fists against Viktor when he was 16, making the latter stumble several steps backwards. He could also survive being thrown through multiple buildings at high speed by Vilgax with no damage. Mad 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, Mad 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, Mad Heatblast's pyrokinesis is replaced with cryokinesis (the ability to create and control cold and ice). Despite these new powers, Mad 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).
