Ah, I can't disagree with you there. The sudden powerful enemies just randomly appearing did throw me off as well.
I'll be pissed if Gon beats Nefelpitou as well though. She's supposed to be this being with a "HUGE POWER", surviving one of Netero's huge Dragonball Z style attacks as well as beating Kaito. I just hope Gon injures her or something and someone else takes over.
Is Pitou is a female or a male.. I prefer to think of her as a female because of the ammount of hentai I've seen for her.
