Pyrotitan is a volcano, one of the first volcanoes ever! But he isn't just a volcano, he is a super volcano that can transform into a humanoid volcano giant! The human race knows him as mount hananuieyluieyblah. His "hide" is as strong as time . (time cannot be brocken, so technecaly it is a simile)
Pyro titan first descovered his powers a few thousand years after he first gained conciousness 216 million years ago. He is also responsable for mans descovery of fire. After seeing how much it benafited man to have fire, he desided to use his powers for good, though he had to do it without being descovered.
His enemy, however, is Hydrotitan, One of the first hot springs to ever exsist. (A hot spring is a naturally heated body of water). Now, unfortunetrly, Pyrotitan's weekness is water. If it touches him he will cool, and seace to exist as a living being.
