Tracker Class
The dragons in this class have highly acute sense of smell to track and find things. The Hideous Zippleback symbolizes the Tracker Class, despite not being in this class.
Deadly Nadder T level 2
The Deadly Nadder is a species of dragons, said to be one of the most beautiful. They are well known for their poisonous and painful spines.
In appearance, the Deadly Nadder is very bird-like: it is bipedal and possesses winged forelimbs. Its small yet keen eyes, equipped with binocular vision, are one of the tools it uses to stalk its targets.
Its body is a vivid blue in color, with a light beige underbelly, while its wings are mottled with yellow, orange and blue. In front of its eyes is its curved nasal horn, which is often used to batter opponents; its lower jaw is shorter and wider than its upper, giving it an overbite (this sets it apart from all the other dragons in the film, since with the exception of the Night Fury all have underbites).
Ringing it's skull are a set of spikes. Coating the tail is a series of spikes that can inject venom into a target. When relaxed, its head spikes and venomous tail spikes lay flat, and when alarmed, they are shot upward to intimidate its foe. The tail spikes can also be used to make a rattling noise which it makes right before it attacks, similar to rattlesnakes.
In terms of behavior, the Deadly Nadder is fast and dangerous, though its potency as a hunter is hindered by the blind spot directly above its nose (possibly due to its large horn). As a result, the dragon relies on its keen sense of smell, often instead of its binocular vision, in order to find its prey. The Deadly Nadder also has at its disposal its tail spikes, which are used as projectiles to stun or immobilize its prey. Its most devastating trait, however, may well be its ability to blow magnesium-fueled flames, which can easily melt metal. The Deadly Nadder is also well-known for its vanity; it constantly grooms itself to stay clean and maintain the luster of its scales. Like the Night Fury, the Deadly Nadder is a picky eater whose diet comprises mostly of poultry.
Rumblehorn T Level 2
The Rumblehorn has relatively large wings, a wide torso, and a tail with a club-like hammer on the tip. Its most notable feature is the heavily armed front half of its body with firm armor plates on the neck and a large lower jaw, a battle axe-shaped muzzle, which is always digging in the dirt, looking for scents, and two, very sharp, elongated horns resembling those of ceratopsian dinosaurs, but lacking a beak. The Rumblehorn has a very acute sense of smell, and is determined to track down and find anything once it has picked up the scent. In total, they look like a mix of truffle pig, a rhinoceros, a battle axe, and a scarab beetle.
It can also shoot long-ranged fire "missiles" from its mouth which initially starts out as a white-hot fireball that quickly solidifies and turns to a warmer color before it ends up in a sooty stony material when it hits its target.
