I had the same reaction when I saw the Nen beast. It's horrible and disgusting. Maybe Togashi-sensei should really draw a horror manga XD  He kills some of his characters brutally too (like the guy who was cut into pieces by Hisoka before the beginning of the Hunter exam).

My guess for the 4 other princes are: Camilla, Choural, Luzoors and Saresare. (I'm judging from their looks only)
