Dagur

Dagur the Deranged is depicted as a young Viking with a muscular build and red, spiky, mohawk-style hair, complemented by a short, patchy mustache and beard. He has green eyes and a prominent scar across his right cheek that cuts through his eyebrow. He also sports several tattoos: three blue lines resembling claw marks near his left eye and on his right upper arm, and a list of names ("Father, Hiccup, Night Fury, Alvin") tattooed on his left forearm. His attire typically includes a brown and metal outfit featuring a chest plate with a Skrill emblem, bracers, knee pads, leg protectors, brown pants and boots, a brown belt with a metallic buckle, and a leather skirt outlined in metal. Initially, Dagur is portrayed as the "deranged" chief of the Berserker Tribe and an enemy of Hiccup and the Dragon Riders, obsessed with dragons and harboring a strong hatred for Hiccup. His personality is characterized by impulsiveness and a preference for action, believing that "attack is the best defense." He is often excited by dangerous missions and is always ready for a fight. Later in the series, his character evolves. While still retaining his energetic and somewhat eccentric nature, he becomes a clever ally to the Dragon Riders, even demonstrating the ability to anticipate enemy moves due to his past as a villain. This suggests a complex personality that blends impulsivity with moments of surprising insight and a capacity for change.
