How do you all think Luffy will respond to their proposal? I imagine his initial reply would be something like "hell no, I don't want to be your boss/father, i just want to be pirate king" which will probably suprise the coloseum warriors a lot! I think in the end though they will convince him because they (or someone like robin/usopp) will be able to see that to achieve his goals he will make many enemies and having allies who are good people will help them against kaidou. In other words: you would expect Luffy not to turn them down because it would be crazy to do that, but at the same time because it's crazy you can easily see Luffy doing exactly that! What do you think will happen?
