These two are from a thing i am creating.

there is a lava tribe and a ice tribe, they hate each other because the ice ones protect "polar bears" (they're more like a tall thing with a white shell in his head xd) so the lava ones have to eat the meat of the polar bears to survive, and that is the conflict between these two tribes

They can have many variations with the ice in theirs head or the magma thing :)

The lava ones are more aggressively and they have lava so... The ice do not react very good with lava (I will submit some examples of the fights they have :D)
