Heatblast

Heatblast is one of Ben's first aliens. He can control Fire and also shoot it. He was Ben's first alien as well. He is a Pyronite from the fiery sun Pyros.

Abilities
Heatblast can project fire from his body. He can also shape this fire into fire balls, discs, walls, and infernos. He can also propel himself like a rocket, and surf on a fire board in the air. He can also absorb fire and is a master manipulator of both fire and heat. Heatblast can also create a super melt down. In the game Ben 10: Protector of Earth, Heatblast can wield flaming fists, shoot a beam of fire, fire rapid sparks, throw firerangs, create a fire tornado, breathe fire like a dragon, ride on a fire surf board, make a large melt down, and he also jumps in the air and shoots fire meteors at his foes known in the combo name as "Armageddon." He also has the ability to move regular rocks with his mind using Geokinesis. When Ben transformed into him while sick with a cold, his abilities changed to the opposite side of the heat spectrum. In this state he could manipulate ice and freeze objects as well.

He is made out of fire, but you can only see a bit because the rocks are covering the fire.

Weakness
While under the influence of an illness, Heatblast's powers are reversed, giving him cryokinetic powers allowing him to control ice instead of the normal pyrokinesis. Heatblast's dependency on heat is also his weakness, as his powers can be negated by sufficient amounts of water or similar fire-extinguishing materials and large amounts of water can extinguish him permanently. He is also unable to lower his own body temperature, which prevents him from touching things without burning them, people included. His feet look like Lodestar 's and Fourarms.
