Komodo rhino

The komodo rhino is an animal from the Fire Nation, bred both as a beast of burden and for its meat in komodo sausages.

History
During the Hundred Year War, the Fire Nation used these creatures as cavalry mounts  or as beasts of burden, often decorating them in red. Komodo rhinos have been used in almost every Fire Nation military operation, such as the Siege of the North and the Invasion of the Fire Nation, although they were most prominently used by the Rough Rhinos. Because of their widespread use by the Fire Nation Army, Fire Nation boot camps had an exercise designed to train new recruits in how to mount and ride a komodo rhino.

Anatomy
The komodo rhino has a thick, "tough as steel" hide, which serves as natural protection for its body. Three large, curved horns dominate its face; two curving down from its forehead and one curving upward from its snout.

The creature's mouth and jaw structure look somewhat reptilian, but the small ears on either side of its head are mammalian. Its torso resembles that of a rhinoceros, but ends in a long, dinosaur-like tail. The rhino's feet are short, muscular, and clawed.

Connection
The komodo rhino resembles both its namesakes, the large komodo dragon and the rhinoceros. It also resembles the ceratopsid dinosaur triceratops. However, its true origin comes from the lizard and the rhino, the animals from which it is hybridized.
