One Piece is filled with powerful villains - but which of them is truly the strongest? With so many great candidates, it's hard to say which one truly deserves that distinction. Let's count down some of the hardest-to-beat foes that the Straw Hats have ever had to face.
Is the strongest villain Big Mom, a woman capable of manipulating the souls of others? What about Kaido, a man who can transform into a dragon and is so hardy that only the strongest can damage his body at all? Is it Blackbeard, the only pirate to ever successfully wield two Devil Fruits? You be the judge.
