Found as a hatchling during one of Drago Bludvist’s earliest conquests, this particular Bewilderbeast suffered the misfortune of being raised by a madman.
Unlike Hiccup or Valka’s warm and empathic approach with dragons, Drago routinely abused his Bewilderbeast to cull out any perceived weakness and to establish a blind loyalty to the self-proclaimed “Dragon God.” What emerged from this torturous crucible was Drago’s perfect secret weapon: A vicious Bewilderbeast that has known nothing but hatred and a single goal… to end the reign of Valka’s alpha Bewilderbeast once and for all.

Icy breath freezes blasts of water
In addition to its icy breath and alpha ability to bend other dragons to its will, the Bewilderbeast is also a formidable force underwater. As a Class 10 Leviathan (the aquatic equivalent of a Titan Wing), a full-grown Bewilderbeast swims at incredible speeds and bursts to the surface to surprising, and devastating, effect.
