winter's dark heart, personified
he is dark and a little on the evil side, though he is not a villain, one could say he is an anti hero of sorts although he takes great lengths to cover that up. he does have a soft side but he has it buried deep. he hates bright places and warmth, preferring it to be cold and dim. his strength is actually physically sapped in warm weather although he can take it, but in hot weather he is much weaker. he is much more comfortable in cold weather, the colder the better. he is fine even in below freezing weather even with ice forming on his clothes and hair, however he can freeze to death if it is too cold, perhaps -1 degrees.
he carries twin katanas and a pistol. he only uses the pistol as a last resort, he is not afraid of killing he just doesn't want to waste bullets, he is very skilled with the katanas and many other weapons. he also can control ice but not water. he can make water freeze if it isn't too hot. he cannot however freeze blood, though he seeks to learn how.
i don't have much of a history for him. he lived in the alps to the north in his world. he would travel between the mountains and frozen northern tundras. he lived along most of the time although he often would help the robbers who lived in the mountains and on the steeps to raid towns in the south, but only during the winter because summer is too warm for him, he is at his strongest in the winter at night. otherwise he wandered the mountains and tundra alone
he somehow ended up in the Multiverse, im not sure how yet.
not much is really known beyond what is written here (aka i haven't figured this character out yet)
