Drago Bludvist

Drago's early life is shrouded in mystery, but Drago himself revealed that he once lived in fear of dragons, and had lost his family and an arm to them. Vowing to end the "tyrannical rule" of dragons once and for all, Drago learnt how to control dragons with brute force and gathered an army of loyal humans under the guise of a "Dragon God", one who had absolute control of dragons. He eventually found a hatchling Bewilderbeast in one of his earliest conquests, and tortured it until it became completely subservient to him. Years before the events of the first movie, Drago visited a gathering of chiefs in an attempt to sway more people to his cause. He entered the Great Hall where an assembly of chiefs were present, promising them peace and freedom from the threat of dragons, but only they chose to bow down and follow him. The chiefs took for a joke and laughed at Drago. Angered by this, Drago left the hal, calling back to the chiefs 'then see how well you do without me!' Moments later, twoarmoredd dragons descended into the hall through the roof and burned everything in sight, killing all the chiefs except Stoick.

As he is portrayed in the film Drago is a sadistic, psychopathic, megalomaniacal, and ruthless madman. Merciless and tyrannical, Drago craved nothing more than power and over the years has assembled an army of dragons to conquer the world.
He is cruel to his allies and did not take failure well; this was evidenced as he violently abused Eret for failing him and symbolically scarred him as a reminder if he disappointed him. As said by Stoick, Drago lacks compassion, conscience or any mercy in his heart, he tortured a Bewilderbeast when it was just a baby and eventually drove it into a mindless, submissive state.
As a child and adult, Drago, like everyone else had a fear of dragons however unlike Hiccup, Valka and Berk he could not see them as elegant, peaceful creatures who can be trusted, just monsters only good for conquest and death, whereas they were friends and pets on Berk they were only warmongering soldiers to Drago.

Drago is a well-built man matching his intimidating personality. He wears a prosthetic arm from when his original was cut off by a dragon attack and wears his hair and beard in thick dreadlocks. Multiple scars run over Drago's face and body, evidence of his past encounters with dragons. His attire consists of a sleeveless shirt, a thick waist belt and a huge black cape made from dragon skin. Attached to his belt, he wears a loincloth, blue trousers, and boots covered in fur. According to The Art of How to Train Your Dragon 2, Drago was designed to look as racially ambiguous as possible and from a land far from the Vikings of Berk. His appearance had several influences from different countries and cultures. His clothing was based of Slavic origin, while his actual physical appearance was based of people from the Mediterranean and northern Africa.
