Does X/Y have something like a battle defining game?
The other games for example have Giovanni, Blue, Silver, Red, Steve, Cyrus, Cynthia, N, Ghetsis x2, Guzma, Lusamine, Kukui, Leon, Sada/Turo and Nemona for example yet I can't think of a really well regarded trainer from Kalos.
The rivals are among the worst of the franchise, Diantha was the walking joke before Geeta and the villain was...
Even Arceus have Volo
