The start of the XY series, definitely started with a bang! Loved how the episode felt, the characters were good here, and the overall interactions were good. Loved the part in the battle where it looked like Clemont and Ash were neck and neck, it's nice to see Ash not acting like a moron at the start. The battle was truly excellent. Clemont was the best here, then Ash was also good, Alexa is decent, Bonnie is below average, while TR is the worst part. I didn't like seeing them interrupt the battle, but Wobbuffet being super charged was funny. Froakie is good, loved how reserved he is.
Is overall this was a good episode and a great introduction to XY. I'll give this episode a 9/10, by far the second best XY episode I've seen so far.
