His hot breath and fiery teeth were truly formidable. Especially since there was no other fire in the world. He could reach into caves with his long arms and drag out people, turning them into hot snacks and toasted tidbits as he munched.
There came a time when it was all too much. Some brave warriors ambushed him from above and behind crushing his skull with large rocks.
Even in death his teeth were still blazing, and the humans realized that they could now utilize the fire for their own uses.
