This demonamic is a really rare one. He enbodies heat and fur.

Talking about "body"... He is a little fat ^^; He likes to cook and loves even more to try what he cooked so... I was once talking about "Demonamics cannot grow fat.." Oh really, there ARE ways ;)
Back to the guy, he can endure quite some time in lava, without burning his fur down. There is not that much fur anyway, yet there is something remarkable about him: his only ability is to not just endure extreme heat, but he too gains resistance to it, the more it goes up.

Side info: he was actually my first try to pixel a bear. ><
