Wow, I think nostalgia just ran in, stripped down to it's skivvies, and did a River Dance while singing in Latin.
And I loved it.
All those flashbacks were so enjoyable to see, the new animation style did them justice. Yeah I know they're total fanwank, but for practical reasons it gave the younger fans a backstory for Charizard so they can understand why he rocks. It's understandable they didn't show Charizard's loses to Blaziken and Dusclops, as the writers are trying to show the youngsters this big salamander in a positive light, and they wouldn't want to show his massive region-disadvantage to Hoenn Pokemon.
I found it interesting Oak just sent Charizard over instantly, since in the past Charizard had to fly over to wherever Ash needed him. I honestly think Charizard would be better off at Oak's lab training against Ash's other Pokemon at this point rather then just fighting the same damn Charizard over and over at that conveniently-placed-to-get-rid-of-him valley.
The fight was awesome, just wish N didn't have to butt in. Hey N, save the hippie stuff for when Team Plasma attacks them.
Iris didn't know Charizard wasn't a dragon type? Hahaha, she's SUCH a kiiiIiIiiiIiiiIiIiiiIiIiiiIIiiiiid!
So all-in-all, great episode. Looking forward to seeing Charizard in action from here-on out.
