Niohoggr

Niohoggr is the dragon of chaos, spawned by the roots of the Yggdrasil tree itself and destined for Ragnarok, feared and hunted by the Norse gods. But despite his nature and fate, he is not the villain; he only wants to live his life, either alone or as the ruler of the Celtic dragons, isolated from everyone. He possesses incredible power, but his irascible nature works against him, as he gets angry easily.

He is irritable, quick to anger, although certain things like good treatment can calm him quickly, proud like a king and honest with a sharp tongue, polite though he is not afraid to behave like a beast. He is larger than any man in size, muscular and greatly beautiful despite always wearing a frown, with long and disheveled dark green hair, his horns are golden like gold and resemble branches or roots, and his scales are the same. He has green eyes with black sclerae that make them stand out, a small beard on his chin, and golden, worn-out wings. When in his dragon form, he is an immense golden creature similar to a winged serpent, but he can control his size to be smaller.
