Belphegor has possessed Jack's body, and claims to be a regular demon. 2 / 7
But in demonic mythology, Belphegor is a Prince of Hell. 3 / 7

And since God smote Jack's eyes out, his telltale yellow eyes are hidden. 5 / 7
Belphegor has also used several very powerful spells other demons shouldn't know. 6 / 7
And joked about being considered a world-ending threat by another demon. 7 / 7
