Drago's Bewilderbeast

Drago's Enslaved Bewilderbeast, is a Bewilderbeast that belongs to Drago Bludvist. This dragon was presumably captured and enslaved by Drago and his forces at some point in the past (possibly by mobilizing by a mass of men and modern weapons), and might have been tortured as well.

Now, he is nothing more than a weapon of mass destruction, a tool, and a slave to the villain.The bewilderbeast also controls the mind of Toothless, causing him to kill Stoick, as well as taking over the minds of all the other dragons, except the babies.

It is the secondary antagonist of How To Train Your Dragon 2.

Characteristics


In comparison to Valka's Bewilderbeast, this individual is dark and looks very menacing, tyrannical and violent. Additionally, he seems restless and being always enraged (the dragon's damaged and rather dirty looks indicate he had been through tough moments). It is not sure if this dragon's true nature is evil, and is possible that he originally had a normal, peaceful character. Understandably, his behaviors are unfriendly and destructive, and doesn't care about damaging the crazed person's forces (crushing several of Drago's men's fleets when emerging, and stepping on one of war or capture machines). His frills are similar to a dreadlock and are quite different from the other Bewilderbeast seen in the movie. This dusty Bewilderbeast has more elongnated tusks similar to those of mammoths than the whiter individual.

It is natural that his mind is always filled with endless pain, grief, desperation, and mostly abysmal rage to everything including his miserable fate. And this anger targeting everything may go towards innocent, 'happier' beings especially for other members of his own race that may cause him envy, loathe, and sorrow even worse.

Origins
His life has been a full of agony and misfortunes. His pain had started even prior to the birth. Ever since, this Bewilderbeast was literally abused to become a war machine. To the maniac enslaver, the meaning of the existence of the miserable dragon was nothing more than a tool, and the wicked wrongdoer kept 'training' the dragon specialized for combats and war usage for life time.

How To Train Your Dragon 2
The Alpha is first seen being prepared for battle, though its breathing can only be seen. Fishlegs says that perhaps its a Class 5 leviathan. Its master, Drago Bludvist, summons it later to battle Valka's Bewilderbeast and after giving a crucial blow to the king, the Alpha stabs it in the stomach, and it immediately takes control of every dragon in the premises, even Toothless, Stormfly, Hookfang, Meatlug, Barf and Belch, Skullcrusher, Grump, and Cloudjumper are controlled. Only a few babies are not posessed and abducted by the new alpha. Drago then orders it to make Toothless kill Hiccup, only for Stoick the Vast to block it and be killed himself. Drago simpiliy smiles, mounts Toothless, and orders The Alpha and all of the other dragons to go to Berk and finish off the invasion once and for all. When the Alpha reaches, it takes all of the Dragons on Berk into its army, and ice blasts the village.

After toothless comes back to Hiccup's aid, The Alpha ice blasts both of them, only for Toothless to unleash his full power, and challenge the Alpha in the final battle. The Alpha gradually looses its control over the dragons, and they all challenge the Alpha, and Toothless deals a final blow to the Alpha, blowing off one of its tusks, humiliating it, defeating it, and realizing this, it descends back into the ocean with its awful master, never to return.
