Noirberus

Noirberus (ノワールベロス, Nowāruberosu) is a Fanged Beast.

Physiology
Noirberus is a large, canine monster with pitch black fur covering its body. It most closely resembles a monstrous mastiff or Rottweiler. Noirberus possesses two small half-skulls, one on each shoulder. There are rings of bony spikes around its neck and ankles, just above each foot. Its long, thick tail is skeletal, as if its spine were poking out of the monster's body. Its eyes, claws, teeth, and nose are crimson in color, as are the insides of its pointed ears.

Abilities
Noirberus is a powerful monster with the ability to breath jets of green fire that can melt rock. The claws on its paws and easily tear through the armored hides of prey while its powerful jaws and sharp teeth can crush bone. The half heads on its shoulders are believed to be sentient and help detect the presence of prey and predators.

Behavior
Noirberus are generally solitary, aloof creatures, but will form temporary hunting packs of three to five or just hunt solo. Sometimes Noirberus form packs consisting of the same individuals from a previous pack or different individuals. Once a pack is formed, they will search for a group of prey and "herd" it, backing it against a wall or corner by biting at them or breathing flames. Once that's accomplished they roast the herd alive with their flame breath and feast on the charred corpses and disband the pack. Noirberus are generally highly aggressive and do not tolerate other monsters encroaching upon their territory.

Behavior
Noirberus generally inhabit subtropical to tropical area such as the Ancient Forest, Great Forest, Sunken Hollow, Swamp, Volcanic Hollow, and the Volcano.
