There were times that beasts were the biggest threat among all the things in such a world. Well, a unknown wizard created a spell on a normal male grizzly bear, and turned that grizzly bear into a powerful fire beast, which ruled the forests because of it's powerful power of fire. The bear had red eyes and had brown and red fur, it controls fire, and even breathes fire.
The wizard saw what the bear done to a peaceful village when the bear attacked it, it was burned and everything was turned to ash. The wizard tried to perish the bear, since he created it, he had to destroy it, but it failed. No water in the universes of the big universe that holds it can destroy it, the darkest or purest of hearts cannot take it down as well, it had no weakness.
One day, the bear attacked a phionex, which was immortal, but was killed. The bear was a nonstop killing machine, that will destroy everything in it's path in centuries to come.
