Boar-q-pine

The boar-q-pine is a relatively large creature which inhabits many regions of the planet. One of these immense beasts got into a fight with Appa, and although it lost, it managed to severely injure him.

Anatomy
The boar-q-pine is an enormous animal, though not nearly as large as a sky bison. It has the body and general appearance of a boar, but its body is covered in quills resembling those of a porcupine. It has a large head compared to the rest of its body, and from it juts a pair of sharp, white tusks. These tusks appear to grow upon nearing adulthood. As they mature, the quills that cover their body during youth tilt backwards, granting them greater agility.

Behavior
Boar-q-pines are known to be extremely bad tempered and vengeful, yet very shy and prone to adorable waddling. Boar-q-pines are carnivores and the main predators of koala sheep. They are one of the few animals that inhabit the Black Cliffs. These creatures are fairly docile and friendly when young, but eventually develop into large, vicious beasts.

Combat


The boar-q-pine extends its quills during battle, allowing it to inflict serious damage even if defeated. The quills latch on to its opponent upon physical contact. During the fight with Appa, a lone boar-q-pine severely injured the bison with a blitz of extremely fast charges. Eventually, Appa anticipated an attack and was able to grab the boar-q-pine and throw it against a tree, prompting it to flee. As a baby, a boar-q-pine relies on its quills as its main defense against predators.

Connection
The boar-q-pine is a combination of the boar and the porcupine. It is also somewhat similar to the extinct entelodont, a giant prehistoric pig-like mammal.
