@Sammsy:
man if there is a lily defense arc, too bad jimbei is on his death bed. if he was healthy he would OWN. i mean imagine a buster call attempting to go to amazon lily and then jimbei kickign ass in the water at the calm belt, all the sea kings there as well. then when they finally reach land they have still hancock and all her warriors to deal with.
and depending on luffy's condition, and finally the climax of the rest of the strawhat crew showing up to save the day, which also helps luffy out emotionally seeing all his friends again and fighting and saving everything with them.
the more i think of it, the more i want it. damnit, fishman island can wait in my book.
I got to say I like the idea of the strawhats somehow meeting up with Luffy to help at Amazon Lily, it would actually make a 'rescue arc' worthwhile and not feel like a massive diversion. The only thing I worry about is if Sanji isn't completely Okamafied that he would never leave the damn place once he got there (actually maybe Oda might have him stay brainwashed for most of it and then right before they leave he snaps back to normal and starts screaming for everyone to take him back lol).

If there does happen one defend AL arc who would be the main antoginist . A vice admiral ?. I think Hancock is powerful enough to take out one VA whoever it be (except Garp) . So we need a stronger villain and Akainu would be perfect for it . However its too early for Luffy to fight Akainu . There's also the Robin connection with Akainu so Robin needs to be there as well .
Maybe it would be Sentamaru and his PX army , only one who could be a challenge to Luffy .
If a hit is sent after her, a Pacifista army would be the best to use especially since they already seemed to have taken out Moria.
