Bonecrusher's Conquest

Bonecrusher's Conquest is a Scauldron that appears in Race to the Edge. Its name was first revealed in Rise of Berk.

History
In the episode Big Man on Berk, the riders are tasked with moving this Scauldron out of one of Berk's fishing routes. However, Fishlegs' sneezing caused the riders to fail at their mission and for the Scauldron to escape. After Fishlegs was hypnotized by Gothi and mistakenly belived that he was Thor Bonecrusher, he set out to tame this Scauldron. However, the dragon fought back and required the rest of the riders to help out. This Scauldron was about to blast its boiling hot water at Meatlug, but Fishlegs snapped out of his hypnosis and saved Meatlug. This Scauldron was then captured and relocated to somewhere far outside of Berk's waters.

Appearance
In Race to the Edge, this dragon appears similar to all other Scauldrons. However, in Rise of Berk, a bluish color is added to its belly, lower jaw, tip of its wings, and tip of its tail. It was also slightly turquoise in colour.

Trivia

 * The change in appearance may have been added in order to differentiate it from the other in-game Scauldrons.
