Heatblast

First Transformation
Heatblast is Ben's first transformation, which was activated in "And Then There Were 10" when Ben tried to take off the Omnitrix and presses the button.

Abilities
Heatblast is basically living fire, able to project fire and absorb heat. When Ben is Heatblast, he can put out a fire just as easily as he can start one, fly by aiming his fire at the ground.

Teleport short distances in a vortex of fire, and possesses superhuman durability, able to survive being thrown through multiple buildings without being slowed. When Ben got a cold and activated Heatblast, his powers were reversed, giving him control over ice instead of fire.

==Weaknesses== Heatblast's powers can be temporarily dampened by small amounts of water and other substances that can extinguish fire, but larger amounts can kill him. He is also unable to touch flammable objects for more than a few seconds, otherwise he will risk burning them.[ citation needed ]

Origins
Heatblast is a Pyronite from Pyros. Pyros is one of the most different planet because it's a sun. Infernal plumes erupt miles into the atmosphere, and raging rivers of molten lava cut massive swaths across the fire-filled tundra. Magma based, all of its inhabitants are composed of a flame-like energy. Drawing strength and nourishment from an almost limitless power source, this world's inhabitants are in need of little else.

Future
In the episode 'Ben 10,000' it is shown that mature Pyronites grows two miniature volcanoes on their shoulders that are capable of shooting fire. Other than that, the older Heatblast is taller and stronger.
