Skullcrusher

Skullcrusher is a Rumblehorn who is Stoick the Vast's new Dragon and later Eret's, in How to Train Your Dragon 2.

Appearance
In comparison to Grump, Skullcrusher is stern and serious looking, and sometimes a little stubborn, (corresponding with the personality of Stoick). He looks like a cross between a dragon, a Triceratops and a beetle (due to his neck plates).

History
It is currently unknown when Stoick acquired Skullcrusher, save that it must have been since Stoick released Thornado. Despite this, the two are shown to be close, with Stoick being comfortable riding Skullcrusher alongside Grump and Gobber.

Following Stoick's death, Hiccup suggests that Skullcrusher pass into the care of their new ally and former dragon-trapper Eret, recognizing Eret's skill and courage in helping Berk defeat Drago Bludvist.

Skills and Abilities

 * Tracking: Like all Rumblehorns, Skullcrusher has a keen sense of smell, enabling him to track anything once he has caught the scent.

Trivia

 * An image error in Empire Magazine led to believe there was a new dragon species with the same name. The description and combination of animals was indeed about the Rumblehorn.
 * Along with Thornado, he is the first Dragon whose current/former rider is deceased.
 * He is the first Dragon who had more than one rider, excluding Barf and Belch.
