Hob Anagarok is a large saber toothed monster that was found frozen in Alaska by Charlie Venkman. He was frozen to render its powers inert if the creature was thawed out of his ice prison he would grow to massive size and attack humanity once more.
The inuit people believed that the gods created the Earth before humans and placed the demon on the land. The humans came and he attacked them but was defeated by them. They imprisoned him in a block of black ice and sank into the ocean. The heat dispersed and snow came to the land.
This monster has the ability to breathe and control fire and display telekinetic abilities even if he's dormant in his black ice prison and can teleport away from danger
