I agree it could be a manifestation, I doubt grandine and metallianica would let igneel fight acnologia 1v1. I also want to know if the dragon slayers blood was running wild because acnologia was present, if he was talking to them and that affected them or if they were simply resonating with them because he's the most powerful dragon/dragonslayer
