Battles in Origins too mediocre for you? Fights in the Mega Evolutions special too weak? Well do I have a fight for you!!!
Seriously, this is prolly the best Pokemon battle I've ever seen! And we haven't even been to the Pokemon League or finished up the Team Flare arc!!! And on top of that, Ash just fought on par with a champion! And it isn't like Diantha is just a pansy of a champion like in the games, the only time before this where her Gardevoir HASN'T one shot her opponent, was the LAST time she fought Ash! And this is also the first time she was forced to Mega Evolve! She did it once, but that was against Team Rocket, so obviously she was just showing off.
So essentially, the XY Anime is amazing, go watch it now!
