Mega Valenark Contest Entry

This is my entry for 's Mega Competition. The challenge is to design mega revolutions for his really awesome Legendary Trio based off Norse Mythology. Valenark is based off Fenrir, a giant wolf fortold to devour Odin and as a result was chained down. And since Valenark is originally Fire/Dark, I made his inside burn bright with flames, and his chains like he chomped them off with his flaming jaws. I also pulled a Primal Groudon and gave him some glowing Norse-ish (?) markings.

If this competition looks like something you'd be interested in, here is the link to it! You still have time!

Odrasil, Yukiga, and Valenark form the Myth Trio, three legendary pokemon who's ongoing battle was said to have nearly destroyed Illusia until they were at last separated and placed in a deep slumber. They each await the day when someone will wake them up once again. The person who does so -- will they be able to control their savage rivalry or will they ruin the beautiful land of Illusia as they did before in the mists of legend?
