hey i know i might get bashed for this, but with the recent chapter, it seems like luffy is definitely having a hard time fighting lucchi and the guy hasn't even changed into his leopard form yet. and with the return of hattori, maybe there is something behind the bird that could make the battle even MORE difficult.
i do know that luffy has yet to use his second or third gear attacks (which are some of the most powerful we've seen so far) and that those could even things up a bit. BUT, luffy has already used up a lot of energy since he's arrived at enies lobby. he beat down hundreds of soldiers, fought blueno (with gear second), ran after robin (used gear third), and is now fighting the strongest cp9 member.
Now do i think that luffy will lose hands down? NO. what i think may happen is luffy defeats lucchi in the non-traditional way. as far as power, skill and discipline goes, lucchi is superior (so far). This makes me believe that either;
A: the building falls down and brings lucchi down with it
B: the buster call somehow interferes
or
the fight is postponed until a later time
now what i'm thinking may be completely wrong and rediculous, but oda is usually pretty unpredictable. he may stick to the traditional beat down of bad guys like most shonen manga, but i think it might be interesting to see a slight twist this time around.
