Heat Jaws looks like Ripjaws with Heatblast's arms and legs and head fire. The Omnitrix is on the left side of his chest.
- Heat Jaws can shoot fire.
- He can breathe underwater.
- He has steel-bending jaws.
- Despite his apparent disadvantages his flames get stronger underwater creating a high pressure stream of scalding fire water.
Heat Jaws has the biggest disadvantage of any alien. His Ripjaws half needs water to live but his Heatblast half needs to stay away from water and using his powers will dry him out.
- Dr. Animo and the Mutant Ray (first appearance)
