Exona is a failed creature experiment created by the devil trying to create a Zangel of his own. These creatures have horns wrapped around the head like a halo crown with a golden star above it, Floating head from the body, a diamond shaped hole on the chest with a golden gem in the center, sharp long craws as fingers, long pointy arrow tail, pointy ears, medium golden bat wings, sharp fangs, white pupils, and black eyes. Females would have a greyish blue with white clothes as for Males have red with black clothes.

Exona was meant to follow the devils command and attack the Zangels but they ended up having a mind of their own. Those who disobey or betray him with be punished by tearing the wings off from there body. Some of them don't make it alive from the punishment being done. Those who lived will be tortured mentally by the devils voice himself.

They can live forever unless something happens to them naturally.
