Viggo Grimborn is the cunning and ruthless leader of the Dragon Hunters, a master strategist who views life as a grand game of Maces and Talons. Unlike his brother Ryker, who relies on brute force, Viggo prefers to manipulate, outthink, and control his enemies through careful planning and deception. His intelligence is unmatched, making him one of the most dangerous adversaries the Dragon Riders have ever faced.

With his sharp mind and composed demeanor, Viggo always seems to be several steps ahead of his opponents. He values knowledge, strategy, and control, believing that power comes not from strength, but from intelligence. Though he often appears cold and calculating, he respects those who can match his intellect—especially Hiccup, whom he sees as both a rival and a worthy challenge.

Despite his villainous nature, Viggo follows his own code of honor. He plays fair in the games he orchestrates, never cheating, but always ensuring the odds are in his favor. He enjoys engaging in battles of wit, psychological manipulation, and strategic planning, making him a dangerous yet fascinating individual.
