The Berserker Tribe was a tribe of fierce Vikings. They were one of the biggest tribes in the Barbaric Archipelago.

How to Train Your Dragon (series)

The Berserk Tribe were a tribe of insane Vikings living on Berserk, located near the Uglithug Territories. Fishlegs is a descendant of the Berserkers. The Berserkers all wear chains and padlocks, so to restrain them, just in case if they go into Berserker mode. They are led by the unnamed Chief of Berserk. The Berserks were known to perform human sacrifices, by offering victims to The Beast.

How to Break a Dragon's Heart

They tried to feed Hiccup, Fishlegs, Humongously Hotshot, and ten other fiancés of Tantrum to the Beast, yet Hiccup struck a deal with The Beast, and commanded the Berserks to free everyone from the prison, under death threat. The Berserks did so, and fled when The Beast set fire to the island. The Berserks swiftly sail away from the island, never to be seen again.

The Berserkers visit Berk when it was time for the annual signing of the peace treaty. Stoick was expecting Oswald the Agreeable, the chief of the Berserker tribe, but to their great astonishment, Oswald's son Dagur (whom Hiccup describes as a lunatic) turns out to be the new chief of the Berserkers, and is now called 'Dagur the Deranged'. Dagur explains that his father has been "retired", and he took over the responsibility of being the new chief, though Dagur doesn't have any qualities of a good chief. After a few events in the episode, Dagur and the Berserkers were forced to flee, but told Gobber to consider the treaty signed.

Berserkers were actual Norse warriors who fought in a nearly uncontrollable, trance-like fury. Most historians believe that berserkers worked themselves into a rage before battle, but some think that they might have consumed drugged foods.


Berserker crest-0
  • The Berserker tribe's crest is a Skrill.
  • After becoming allies of the Dragon Hunters, the Berserkers start to use arrowheads laced with Dragon Root.
  • A running gag in the series is that the Berserkers, particularly Captain Vorg, are thrown overboard, usually by Dagur. They would then swim back, only to be thrown off again.
