Valka is a Dragon Rider who, in How to Train Your Dragon 2, is Hiccup's mother and wife to Stoick the Vast. She was taken by a dragon and presumed to be dead. She chose to stay away, believing her family would be better off without her. Valka eventually meets Hiccup during his journey to stop Drago Bludvist. She is loosely based on Valhallarama from the books.
Drago Bludfist, okay, he's a little scary looking...He definitely looks like a villain. And, MAN, look at that ugly mug. A face only a mother could love, if he didn't kill her before he developed into...THIS!!! And I thought Alvin was ugly. lol XD
