King Asmodeus

The powerful king of all demons, and ruler of hell, deep underground. He can travel to hell, to earth, control his dark powerful energy, and he can make deal, in cost of a soul, with his own necklace, that has unbreakable red crystal.

His scary look, and massive height, all demons can him respect, and royal to their king. He got lots girls, but he sometimes likes males too.

When someone tries slay the demon, end up being killed, or crushed, or even turn into the his own slave. Plus, he's immortal, so that is useless to defeat him.
