|“||Look, Berk's dragons will follow their Alpha. So, we'll pay you to capture him and bring the flock to us. [src]||”|
|— Ragnar to Grimmel|
After Hiccup and the Dragon Riders freed another batch of captured dragons, Chaghatai Khan, Ragnar, and Griselda the Grevious decided to hire Grimmel the Grisly to hunt Toothless, the last Night Fury known in existence. They also offered him a female Light Fury to use as a bait for Toothless.
The three Warlords and Grimmel then travelled to Berk, but found the island empty. The latter discovered the route the Berkians have taken and the four hunters sailed after them.
Soon after Grimmel's tower was attacked by the Dragon Riders, Chaghatai, Ragnar, Griselda, and Grimmel planned their next move. They were continuously disrupted by Ruffnut Thorston, so they decided to release her and follow her to New Berk. There, Grimmel managed to capture both Toothless and the Light Fury and brought them back to the Warlords.
However, the Dragon Riders came to rescue their dragons, and began fighting the Warlords and the other Trappers. Later during the battle, Gobber the Belch, Valka, and Eret were brought by their dragons and were directly confronted by the Warlords. Ragnar is last seen when he fought and nearly defeated Gobber, but was forced to flee in terror when a pack of Hobgobblers came to the latter's rescue. It is unknown if Ragnar had survived the Hobgobblers' attack.
Ragnar can be seen as the most jovial and the least mature of the three Warlords. Even when he and his colleagues are discussing plans to catch more dragons, he cannot help in goofing off in front of them, much to their chagrin.
Abilities, Skills, and Talents
Dragon Hunting: It is assumed that Ragnar is an expert dragon poacher, since his rank is among the Warlords, the best dragon trappers.
Combat: Ragnar is a very capable fighter, as he is able to overpower Gobber, a veteran Viking warrior, in a matter of seconds.
|“||Grimmel! My old friend! [src]||”|
|— Ragnar to Grimmel|
Ragnar appears to have known Grimmel for many years, even referring to him as an 'old friend'. This fondness, however, is not shared by Grimmel, as he resents Ragnar's incompetence.
