White-eyed demons were a very powerful group of demons, known for being among the oldest and strongest demons in all of Hell together with Cain and the four Princes of Hell. They represented the highest demon rank of authority in Hell, following the Princes of Hell. They were of such strength that while they couldn't kill angels with their own power, they could overpower them with ease. They instilled great panic in other demons as almost all other demons were terrified of them.
