Gobber the Belch
Gobber is the blacksmith of Berk and Stoick's right hand. He likes to construct useful weapons and devices. His dragon is a Hotburple called Grump.
In order to defend Berk from attackers, Gobber has built several catapults, which can shoot large stones and sink whole ships.
Gobber's Axe and Mace
As a blacksmith of the village, Gobber supports Hiccup and makes various weapons. Gobber's hand was bitten off by a Monstrous Nightmare, so in its place he carries a prosthesis in the form of a mace.
