User blog comment:Whitelordwizard/new Alpha dragon??/@comment-26219548-20150508114647

Although these dragons look huge and ferocious, I doubt that these are alphas. The Bewilderbeast and Red Death, which are alphas did not appear in the concept art. I think that Rise of Berk would include these 2 dragons since they appeared in the movies. As they aren't in the concept art, I believe that these are not alphas.

But of course, they could be alphas. And that'll be so cool and amazing!!!
