Well that was made for the US first then Japan...
So I don't know if that counts....
No, actually, the only "anime-related" thing that they ever made for the US was Pokemon Live, as absolutely zero percent of the Japanese had a hand in the making of that stage show.
As that episode/it's script was clearly made by the Japanese (otherwise, the opening wouldn't list all of those Japanese names in the credits), it still counts. They just decided to air it in the US first, that's all. It's not really all THAT much different than how Sonic X airs things (I mean, they were created in Japan, yet air everywhere else BEFORE Japan airs them).
@Porygonsquared: about your GL arguement, I viewed GLs as not being very strong, anyways (In fact, they are probably as strong as, if not marginally stronger than, JJM are, in reality). I mean, first off, the fact that they seem to lose to rookies isn't really convincing for me to believe that they are actually very strong trainers.
Heck, the worse case of GLs losing was in Hoenn. I mean, Yes, Ash was very experienced, but that doesn't mean that most of the pokemon on his team that isn't pikachu are experienced from the getgo, or especially that they should be able to take them down THAT easily. Heck, 3/4ths of the GLs in that region were pretty much joke wins (meaning, the way they were beaten were similar to JJM's losses, be it Deus Ex Machina, or a One Hit KO.). I mean, if it was his Kanto team, or heck, his Johto team who did this, I'd at least be more understanding, since they are more experienced (And by "Winning that way", I mean with actual skill than going "OMG Hyper mode" on us like Pikachu did with it's three wins in that region.)
Heck, Brock also got the short-end of the stick in terms of battling prowess. I mean, His Foretress lost to a rookie Cacnea, for goodness sakes! I mean, I understand that he doesn't enjoy battling, but that doesn't mean he should be treated as being a joke opponent of the likes of JJM.
As for your strength issue, It's far more than just aggressiveness, it's also trying to save someone no matter the cost (and if they can't save them, it's only because the task IS too impossible). I mean, at least Dawn tried to save Pikachu from TR with that Mechlekid (though I DO wish she also tried to climb up the machine. I mean, if Ash could do it, she can as well.), When Manaphy was kidnapped by Phantom in her movie, did May even TRY to save it (if not by swimming to it, then at least using her Squirtle)? No, she never even tried.
The only time that I remembered where Misty EVER hesitated in regards to saving someone was Oddish, which even then, that's only because She didn't have a flying type at the time (and an ACTUAL water/flying type, at that.), and even IF she did, it would have been far too risky to actually try to use one to save oddish, because it would have had a high probability of being sucked in as well. (Before anyone mentions Pidgeotto, I should point out that the only reason why Ash was able to use Pidgeotto without worry was because Bulbasaur was able to whip the hose into submission, thus preventing it from sucking up anything. Also, Bulbasaur was gripping the soil to avoid being sucked in (as evidenced by it's relative difficulty in regards to getting back to the hut.).).
