Backstory: Mogral was a military experiment long before the virus. Known as Experiment X-693, he was a killing machine designed for striking fear in the hearts of foes. He performed his duties well, but when the virus struck, he destroyed his cruel masters. Their guns could barely pierce his tough hide. Upon destroying the research base, he fled into the hills. He knew what the humans were capable of, and he didn't want to be exploded or roasted alive. In a world of animals, he has found a lair in a huge chain of mountains. Using the immense strength of the Lion and the fire of the Dragon, he has hollowed out a base of operations. He is known very well in the town below as an unpredictable animal. Depending on which head is dominant at the time, he might destroy animals, let them past without a fight, give difficult riddles (similar to the Sphinx), or demand the signing of contracts to pass (with things in Mogral's favour in it too). Because of this, he has become feared in the region.
Anything Else? I know that in the Greek myths the Chimera had three heads (goat, lion, snake), but I envisioned him to be partly the mythological Chimera, and partly the Chimera from things like Dungeons and Dragons (dragon head, wings, no goat). So please don't yell at me for inaccuracies. Also, is it okay if the dragon, or maybe snake head could speak to humans?
