I have really mixed feelings about Torterra's loss to Drapion. I realize that it made a lot of sense to have Drapion take down three of Ash's Pokemon like that, making a super-comeback. But now Torterra is Ash's only Sinnoh Pokemon to not have a single victory against Paul, sans Gible of course. Pikachu's beaten Froslass, Staraptor's beaten Weavile, Buizel's beaten Gastrodon, Infernape's beaten Ursaring, Aggron, Ursaring, Ninjask, Ursaring, and will obviously beat Electivire, and Gliscor seems very likely to either beat or draw against Drapion. However, Torterra is the only one of Ash's Pokemon that could afford to lose to Drapion. Gliscor just returned and needs to show off its strength, so it couldn't lose. Pikachu's finally got his uber-powers back, so he couldn't lose there. And Infernape's...well, Infernape. So I guess that Torterra was the logical choice to lose.
Also, I may love Infernape, but having it take down Ninjask on top of Aggron and Electivire seems like overkill. Infernape may have all rights, reserves, and copyrights to kick Paul's butt, but I would have rather seen Gliscor's aerial maneuvers or Torterra's ultra-defense take on Ninjask.
And now that I'm finished with my rants...Infernape still rocks out loud. And Drapion is absolutely insane powerful, just like Ursaring. Heck, Drapion may be even worse, given the fact that it poisoned five of Ash's Pokemon. And the one that it didn't poison, it crushed without mercy. So, yeah. Wow.
