According to various profiles on Wildmutt, the porcupine-like quills on his back supplement his radar sight and can also serve as weapons, either protecting him while he's rolling, or as projectiles fired off at will. However, a loud sound or a horrific smell can overwhelm a Vulpimancer. Though without eyes, Vulpimancers use the gills on their neck for thermography echolocation and use heightened senses of sound and smell. Wildmutt is a Vulpimancer (a play on vulpine, which means fox) from the garbage planet Vulpin, an animalistic creature that fights with animalistic speed and strength yet unable to speak. Greg Cipes - Ben 10: Ultimate Alien (As Kevin in 'Inspector 13').Dee Bradley Baker - Ben 10, Ben 10: Ultimate Alien & Ben 10: Omniverse (vocal effects).He first reappears in 'A Jolt from the Past' trying to catch Corvo. In Omniverse, for both Bens, he looks the same as in Ultimate Alien, only his eyes are once again connected to the fire on his head, his shoulder plates slightly tilt up and the 16-year-old Heatblast is taller and much more muscular. Ben later regained access to Heatblast in Ben 10: Ultimate Alien, with his 11-year old self's Heatblast form making an appearance in 'The Forge of Creation'. During the original series, when Ben caught a cold, it effected Heatblast by giving him cryokinetic powers instead of the normal pyrokinesis. Heatblast is Ben's first transformation, accidentally activated in the pilot episode of the original series, 'And Then There Were 10' when Ben was trying to remove the Omnitrix immediately after it first attached to him. They only seem to be weak against sufficient amounts of water or similar fire-extinguishing materials that may nullify their attacks and, circumstantially, extinguish them permanently. Pyronites are unable to lower their own body temperature, which prevents them from touching anything not fire-proof. Heatblast is a Pyronite ( pyro- meaning fire) from the star Pyros, a humanoid magma based life-form with the ability to control heat at will in various ways, including flight by firing at the ground to propel himself like a rocket.
