Imu, Akainu and Blackbeard are the only bad guys left that could defeat Gear 5 Luffy. Imu is for the end. Blackbeard isn't ready yet. Had trouble against Law. Probably needs a third DF to take out Shanks. Egghead will be over soon, and Elbaf won't be long either. Therefore Akainu will fall to Luffy while Teach grows in the backround. The Fleetadmiral is frustrated with his peaceful pencilpusher job, he wants to fight. He is also quite manipulative, remember Squard. He will lure Luffy to Marineford by putting on a public execution of people close to Luffy. My top guess is Barto.
