His name comes three Japanese words: Sui - Acid, Doku - Poison, Kujo - Destruction. He is a Dire God of Destruction. His claws carry a deadly poison, each step he takes leaves death in his wake, leaving soil barren of life for centuries. His paint is normally dormant, though at will he can 'activate' it, causing it to become highly acidic, able to eat through anything in seconds. The fumes his paint gives off when he activates it are highly toxic, breathing it in for longer than a few seconds will cause poisoning, the longer it's breathed in the sicker a wolf will become. He was once able to fly simply by running through the air, but when he was banished from the land of the gods the ability was taken from him so he could not return. Normal sized RPWs look like pups beside him; he is quite large.
He lost one of his forelegs in an intense battle with his sister, the Dire Goddess of Creation. She challenged him after he had become consumed by the desire to destroy and could not be satisfied, leaving a great scar in the RPW world where to this day nothing grows and no life survives. It is known now as the Valley of Silence and it is where he makes his home. The loss of his leg broke the frenzy that had come over him, but he was banished from the land of the gods so he could never wreak such destruction there, should he ever become consumed by his destructive desires once more. He lives as a fallen god now, in solitude mostly. He is not inherently evil, but destruction is rarely looked upon as anything good, and so he is viewed as such by most.
He is very aristocratic; he speaks rarely, but is quite formal when he does. He is quite arrogant, seeing himself as above many things, and it becomes obvious when he speaks, for he is often derisive, finding interacting with lower beings to be distasteful. He will not harm any who do not give him reason to do so, but he becomes annoyed easily, and that is often all it takes for him to deem you unworthy of life. He is generally stoic, showing very little emotion, even when annoyed or angered.
