Yeah, I saw the ending of Cowboy Bebop here the other day, and I thought maybe it would be itneresting to have the same kind of ending in OP.
Basically I hope that Crocodile will be able to revenge his defeat against Luffy. The best thing would be if Croc dried up Luffy, and then poisened him with his crook. And watch him die - that would be great, watching Luffy slowly die.
I also hope that Nami will die/leave the crew in the upcoming arcs. Basically she`s not needed anymore. There are more than enough sluts in this world.
Who would you like to die of the Mugiwaras?
