Forum:The final villain will be no one other than Blackbeard.

It won't be the World Government. Luffy has no special interest in beating the WG. That's Dragon's thing.

Blackbeard is the greatest pirate rival of Luffy. He'll certainly be the final obstacle of Luffy. At Raftel.

Its pretty obvious, Right now he has the most strength haveing a devil fruit that can beat Ace, and Now having Whitebeards, Plus he is the main protagonist, but I dont think he'll make it to raftel.
