Heat Jaws[1] is the combination of Heatblast and Ripjaws' DNA. He cannot be accessed unless the faceplate of the Omnitrix is broken or by using the Biomnitrix.[note 1]


Heat Jaws has Ripjaws' torso, however his arms and legs are essentially Heatblast's. Also, the fin that Ripjaws usually has on his back is replaced with a line of fire.

Powers and Abilities[]

Being part-Pyronite, Heat Jaws possesses pyrokinesis similar to Heatblast. Surprisingly, his flames actually get much stronger after Heat Jaws submerges himself in water.

Being part-Piscciss Volann, Heat Jaws' sharp teeth and jaws are as powerful as Ripjaws', being able bend steel. He can also breathe underwater and has a glowing lure.

Heat Jaws has enhanced strength and durability and is resistant to fire attacks.

Dehydration/Heat Exposure

Because his Piscciss Volann DNA needs water to live while his Pyronite half generates enormous amount of heat, Heat Jaws quickly gets dehydrated on land.

  • Heat Jaws' voice is the same as Heatblast's in the Original Series.
  • Heat Jaws was designed by Thomas Perkins,[TP 1] but he always wanted to go back and do a take that was more uniform rather than having each body part belong to only one of the aliens.[TP 2]


  1. Diamond Matter, Heat Jaws and Stink Arms are three fusions which were originally created by a broken, prototype Omnitrix. All three fusions are possible with the Biomnitrix, however, they might differ in aspects such as appearance, powers and weaknesses due to the fact that there's no evidence to support the idea that the broken prototype Omnitrix creates fusions the same way as the Biomnitrix.
