The two faces of my hellhound, Volitix.
Volitix's face is removable since it was ripped off just before his death. His face retains his original fur color when he's not wearing it. The fur changes to match his new fur only when he wears it.
Volitix was not born a hellhound; he was revived as one. Unlike other hellhounds, Volitix has a sworn duty that he must uphold. So long as he upholds his duty to protect those who are wrongfully bullied, Volitix can not die and be reborn.
Volitix is in no way evil, but he does control dark forces. He hardly ever uses these forces to attack since his exposed face alone is enough to intimidate the bullies; however, he will use them if necessary.
