DreamWorks Dragons: Riders of Berk
The Hairy Hooligan tribe are expecting an annual visit from the chief of the Berserkers, Oswald the Agreeble. But then, when the Berserker ships arrive at the island, it is shown that Dagur, Oswald the Agreeable's son, has become the new chief of the Berserkers, and is now given the new title — Dagur the Deranged.

He came to Berk to renew the peace treaty between the Berserkers and the Hooligans. He spent most of the time insulting his father, and looking for dragons to kill. Later in the episode, when Barf and Belch bursts into the Great Hall, he led the Berserkers in catching them. Barf and Belch were brought to the arena so that Dagur and Stoick could kill them. Dagur was stopped by an "attack" staged by the other dragons, directed by their riders via hand signals. Dagur was forced to flee, but told Gobber to consider the treaty signed.
