La Parka

Once a normal person, he was killed and his spirit selected to work as Mr. Bones' Avatar (Body).

Soldier of the Rattler
Unlike most people, this person wasn't granted eternal rest upon his death; instead his soul was chosen to replace the name of the spirit that was engraved in Hell's eternal throne. Mr. Bones had chosen this man to be his avatar in the ring, and maybe participate in the Holy Grail Wars, but mostly wrestling.

He is vulnerable to holy weapons such as Holy Light Tubes. When these weapons are used against La Parka it will heavily weaken him to the point that he needs to go back to his phylactery to recover.

It was this way that he was defeated by La Parka Negra, a cursed being that attacked La Parka on a few occasions.
