Luffy: Lucci, it was just awesome how took 3 (or 2, i cant remember) rokuougans and STILL got back up and kept fighting, even though it could have killed him.
Zoro: has to be Mr. 1, just how zoro was pushed to his last fibers of energy to win that fight, and he used one of my favorite moves in the show in that fight (lions song) it was just an awesome move.
Nami: vs. Kalifa, only two to chose from, but she actually knew what she was doing here, and held her own against a cp9, and even had the upper hand towards the end.
Usopp: of course against luffy, usopp just dominated this fight, even though he lost, he still kept luffy at bay, and even beat the crap out of him at times, it was just complete ownage for him.
Sanji: against Mr. 2, this fight sanji was actually even throughout the entire fight with his opponent, unlike in arlong park where he got the crap beaten out of him then returned the favor, and in cp9 where he just dominated the fight, here he had a challenge, and did a lot of awesome moves in it (veau shot ftw!)
Chopper: against Kumadori, in this fight he was completely getting his ass handed to him, but then he ate a third rumble ball and completely destroyed kumadori (too bad, he was my favorite cp9) and went on to give his nakama some trouble later on.
Robin: against spandam, this isn't really a fight, but she put up with so much beating, then once the handcuffs came off, she got some much deserved revenge, and the back break at the end was simply awesome.
Franky: Fukurou no doubt, the fight when they were above the water was just awesome, in animation and just fighting in itself, and the coup de vent at the end was just completely pwnsome.
