@NoNickNeeded: I know Zeref didn't seem allmighty when fighting Ultear, but he was also holding back due to his value for human life. The reason why his death magic is so dangerous is because it's likely an absolute magic. So no matter how strong someone is, the moment he or she comes into contact with that death magic it's over and before such magic numbers don't really matter either. But I wasn't even serious when I commented about the Zeref vs 10 Juras, since it can never happen.I just wanted to point out that Zeref may be able to handle the fight, but I didn't say it would be a piece of cake for him.
