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
Astrid is a strong female character even though she is not the lead. In the absence of Hiccup, the lead male character, Astrid stands up to Drago Bludvist who is the main antagonist in the story. Drago is bigger in size, and yet Astrid is fearless in this scene, protecting her friends and dragons.
