Heatblast

Heatblast is the first alien Ben ever turned into. He can control fire.

Appearance
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.

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 Ultimate Alien, Heatblast's appearance is slightly altered. His eyes weren't 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.

In Ben 10: Protector of the Omniverse, he looks like his 10-year old self in The Forge of Creation.

In Ben 10: Hero of Heroes, he looks like his OS self but his eyes are not connected to his eyes.

In Ben 10: Omnitrix Unlimited, he looks like his OV self.

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 also possesses super strength and durability as well as agility.

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. He cannot swim in water.
