Buffalord

The Buffalord Dragon is a large probably Boulder Class Dragon introduced in the Race to the Edge series.

Description
This big, Boulder Class Dragon is possibly the laziest Dragon, even lazier than the Hotburple. It can blow up, like a blowfish, and shoot spines from any part of it's body. It has an armor-like scales, that can protect it's skin.

It has a head similar to the one of a tortoise, with horns growing to the side and forward, like a yak. It has very big wings, and small legs.

Firepower
Buffalords fire is uncontrollable, and can explode in an instant. Also, it seems like the Buffalord can't control when will he fire, like that those explosions happen randomly.

Blowing up
Like a blowfish, a Buffalord can blow itself up to look bigger, and to scare predators.

Shooting spines
Similar to Deadly Nadders, Whispering Deaths, Screaming Deaths and Razorwhips, the Buffalord can shoot spines from any part of it's body, but it seems like he can only shoot them when he blows up, like a blowfish.

Trivia

 * Buffalords appear to be lazy, or maybe only very slow and vulnerable Dragons.
 * It seem that Buffalords are a Dragon version of a blowfish and a tortoise.
 * It is still unknown, but will be explained soon, why Buffalord needs to be brought back to Astrid. It is possible that they are like little ducks - if they want to survive, they must be with someone who found them and took care of them.
 * It seems like that Buffalords are, or at least have a body part that is a cure for the Scourge of Odin, probably a disease, which effects are still unknown.
 * It is possible that Astrid has the Scourge of Odin, and the Riders must bring the Buffalord to her to cure her.
 * One of the Buffalords roars is actually a reused roar of the Red Death from the end of How to Train Your Dragon film.
