Gobber's Nemesis

Gobber's Nemesis is a Boneknapper featured in Legend of the Boneknapper Dragon.

Appearance
As being a Boneknapper, this individual is fairly a large dragon.

Character
He and Gobber the Belch have been rivals for quite long periods, however this was mostly due to the Boneknapper's objective to gain the perfect bone piece Gobber had with him, and Gobber didn't know about the species' nature to seek for bone armors.

As long as his desire is fulfilled, he seems very friendly and playful to humans, like that of dogs. He is also quite generous in order to carry and send off Gobber, Hiccup and the other members of the gang to the island of Berk, while letting them ride on his back.

Abilities
Strength: He is capable of carrying Gobber and all the members of the gangs on Berk (with a sheep as well) with ease.

Stamina: Being a fully-grown Boneknapper, he has high leveled stamina to keep wearing the bone armor for his lifetime.

Fire Breath: He bursts a rapid torrent of flame from his mouth that is unique to his species. This fire doesn't seem to be the hottest of all, but due to his size the range of the attack is quite large.

Thundering roar: He seems to have tremendous lung capacity as that his single roar can blow away surrounding objects vigorously. Without the special bone piece, however, the dragon's roar is nothing more than an air leakage sound from the vocal cord. How this logically works is currently unstated. This is also a mating call as well.

Trivia

 * Despite being featured as a cameo in the first film, and having a major role in the Legend of the Boneknapper Dragon special, no other media or website has talked about the Boneknapper, with the exceptions of the Book of Dragons Short,Dragons: Rise of Berk and School of Dragons.
 * The existence of the Boneknapper raises the question as to whether the Hammerhead Yak and Hammerhead Whale are also more than just fabrications. If so, it means that Gobber has seen Thor himself.
 * After the Boneknapper gets its ability to roar back, Fishlegs notes its current roars appear to be a mating call. So this whole time it's been chasing Gobber because it was... frustrated.
 * In Rise of Berk, the dragon's eyes change color from green (hatchling) to red (adult). Gobber's Nemesis in Legend of the Boneknapper appears to have green eyes.
