@onemoment:
Look at Moria. Upon meeting Kuma, he at one point says "I know all about your power. Want to fight?" So, this most likely means that Moria knows about Kuma's ability despite probably never fighting him before. With this, I think we can assume that more people in the Grandline, the high level fighters, know more then we think. They'll be a point where we can't assume that Crocodile would beat people just becase they don't know his weakness, Moria probably knows it (being a by all means higher level of shichibukai) and people that are higher on the food chain then him (and smarter then Luffy for that matter) probably know it too.
What is the point being made here? Moria and Crocodile were apart of the Shichibukai at the same time and they know all of the members of the Shichibukai. They are a gruop after all, even if they don't work together. The only thing we can assume from this is that the Shichibukai pretty much know each others powers.
@kingoffans:
Actually even without info, Lucci would probably figure out the weakness during the battle. People assume that just because it almost killed Luffy to find it out, it will kill Lucci too. Lucci is much stronger than Alabasta Luffy. And there's no way he'd walk straight up to an opponent and start shaking him like an idiot like Luffy did completely leaving himself defenseless. Lucci could just use his Soru and Tekkai against Crocodiles attacks until he figures out his weakness. Not to mention Lucci is soo much smarter than Luffy is, it would probably take him a minute at most. Don't forget this is the same guy who figured out Franky's connection to Iceburg, deduced the mechanics of gear second and had presence of mind to flood the tower of hesitation. Let's face it, the man's a genius.
Indeed, Lucci would not have done that but punching sand solves nothing and soru wouldn't help if you're caught in one of those sandstorms and tekkai only makes your body as hard as iron, and is still actual flesh meaning that any of the dehydration abilities would be a huge problem.
@onemoment:
Back to Moria vs. Lucci, again, Moria would win. For those arguing Lucci's speed, Moria's doppelman could block Luffy's gattling, which is damn fast and precise even if it's not gear 2, and avoided Sanji's kick..and Sanji's always had soru like speed. Plus, which Moria's size "shigan" would take several more hits to kill Moria then the average man, whereas Moria has his shadow stealing. It's Moria's advantage.
Indeed. Although Lucci is at the top for physical fighters Moria's fighting ability is very tricky. He is stronger than we see because really we've only seen him sit on his butt or use his shadows. It is obvious that his physical abilities are strong but he is just lazy, and that's why he uses Doppelman who has some pretty amazing abilities.
@kingoffans:
I don't think we've seen enough of Moria to make a statement but from what we've seen so far, Moria is definitely a force to be reckoned with.
Indeed. It would be nice to see more of Moria, and we will because he has a lot more under his sleeve.
