Ok, I have a pretty funny idea for what might end up happening in this arc. I'm not sure if the idea has been posed yet, but thinking about it makes me laugh.
In this arc, we will most definitely see a "Female Luffy".
Here is the scenario. Marguerite will sympathize with LUffy after his explanation of what happened at the Sabaody Archipelago. However, she will realize that Boa Hancock has just arrived on the island. She knows Luffy will be executed on site, so she devises a plan. Because she had already observed Luffy inflating, she'll ask him if he can do it at will. Once he agrees, she'll ask him to inflate his chest, hips, and tuck those "Golden Balls" away. She'll throw on some skimpy clothing, and Luffitia (or any other female version of "Luffy" you can think of.) will be born.
They'll get back to the villiage and say they lost track of the Male, but found another Female warrior wondering the jungle.
After this, hilarity and an avalance of sexual jokes will take place.
Hahahahaha! I doubt it will happen, but this would be pretty funny. Plus, he can do it too!!
I actualy had one more thing to throw out there. I'm not sure if anyone watches "Heroes" but the main character, Peter, pulled a Kuma last night. He has an ability to move through space and time, which he can use on other people too. He put his hand on another charcters chest, and sent him to Africa. Hahaha! It was kinda funny, seeing as this just happened like…two weeks ago.
