Heatblast (voiced by Steven Blum on Ben, Michael Reisz and Charlie Schlatter on Kevin and Grey DeLisle on Gwen in the first series, David Franklin in the live-action movie and Dee Bradley Baker in the third series) is a Pyronite (pyro meaning fire and "nite" as in ignite) from the star Pyros. Heatblast is Ben's first transformation, which was activated in "And Then There Were 10" when Ben was tampering with the Omnitrix upon it first attaching to him.
Heatblast is a magma-based life-form that can control fire at will, either projecting it in a wide range of forms or absorbing it into himself. He can fire streams of flame, create fireballs, manifest tornadoes of flame, utilize said tornadoes to carry himself and others short distances, and radiate heat in all directions for a localized explosion. He can also achieve flight by firing at the ground to propel himself like a rocket. Apart from this, Heatblast is also a highly durable alien, able to endure being thrown through buildings without being slowed. While under the influence of an illness, Heatblast's powers are reversed, giving him cryokinetic powers allowing him to control ice instead of the normalpyrokinesis. 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.
