Destroyer

"I end this Now!"

The first time Cain tapped into his true demon form was during the last fight he had against Seth [link] Prior to that point he had always known he was never using the full extent of his power, mainly because he was afraid of what he might become.

During their fight he became enraged and his energy began rising to the point that even Seth was worried. Suddenly Cain let out a roar as he was engulfed by an enormous explosion of black energy. When the dust cleared "Cain" was no where to be seen, only a hulking beast that's very power made the earth around him crack and shake, as if trembling in fear.

One glimpse of this monstrosity and Seth fled. It appeared as though "Cain" was going to let him escape when suddenly his eyes turned to his prey (who was now hundreds of feet away in the sky). In an instant Cain had charged up an energy attack and fired it, the blast seemed to chase after Seth like a missile and on impact created an explosion akin to nuclear bomb. Cain then fell to the ground unconscious. (Seth would actually survive this, though barely, and would then head back to Ragnarok where he gets absorbed by the imperfect Abel [link])


The first time Cain accidently used this form he had absolutely no control over it, and thus it was fairly different in appearance/power to the more controlled version [link]
This version was much larger and had a physique closer to a Werewolf then Human. One could say this is Cain's version of Ichigo's "Fully Hollowfied Form" in the way that while it is incredibly powerful it behaves like a violent, mindless beast.

(NOTE: Wow i'm happy I was finally able to do this. Ever since I had come up with a form similar to this for Cain I had wanted to draw it but every time I had in the past it had turned out horrible. He looks pretty damn bulky, I did this because I always imagined him moving around like the Hulk, jumping around and smashin shit, ya know? HULK SMASH! Plus I wanted to make him look abit like the Lycans from Underworld and I've always loved their design.)
