Who knows what Kyouka's powers are, it made me think with her Reinforcement Curse, she might have surrendered most of her strength, but once it's returned to her she will be at full power.

Gildarts claimed that he would return when Fairy Tail was number one again. So it is a possibility.

E.N.D. would be like Diablo, he would open a portal to where the Dragons are, Team Natsu would follow shortly after him. E.N.D. might be stronger than he was last time, enough so that he would be able to kill Igneel and most of the dragons.
