Heat Jaws

Heatjaws is one of to fusions from "Dr. Animo and the Mutant Ray".

Heatjaws was a combination of Heatblast and Ripjaws DNA. He basically had Ripjaws' torso, head, and tail flap, but had Heatblast's arms and legs. Also, his dorsal fin is replaced by a flame.

Heatjaws' combination surfaced extreme problems. His Ripjaws half needs to stay out of the heat or he'll dry out, but Heatblast's half constantly generates heat, making him dry out quickly. His Heatblast half has to be dry in order to use his flame abilities, but Ripjaws' need for water caused him to have weak generation of heat. He also couldn't stay in the water, even though it is crucial to Ripjaws, because it would extinguish Heatblast. Ben actually revealed that Heatjaws was "not the best combo".
