Jabberwock

Jabberwock (深淵の獣（ジャバウォック）, Jabauokku) is a shape-shifting creature, capable turning into even humans. It has a taste for human meat.

Plot
Smelling a human, a Jabberwock arrived at the Santos, where it was attacked by Goblins and which it killed with ease. Pretending to be a human, it was easily let inside the human's hiding place and started killing them. Maria attempted to fight the Jabberwock, but was unsuccessful and saved in the last moment by Riseman Sawyer. The Jabberwock bit off Riseman's arm, but to it's surprise it regenerated back. Following a fight and using an Elder Dragon's bones, Riseman burned the Jabberwock.
