Dyura, the ice demon dog, is tough against the cold. He manages to survive harsh winters and below zero temperatures...
The ice demons power is the one that allows him to survive such cold. Though this may sound cool, his power, however, can turn against him.
Dyuras blood is blue in color, and can freeze whenever the ice power becomes active. When this happens, the frozen blood can pierce through Dyuras body in the form of spikes. During this, Dyura gets severely damaged with multiple wounds. This happens randomly and it cannot be controlled easily.
Corvey, the ice demon cat who injected Dyuras power in the first place, can cause this to happen to Dyura as well. He uses this against him, keeping him under his control, as well as keeping him trapped in his ice cave using the chains of the stars given to him.
This idea is a WIP!
