One Piece and Attack on Titan crossover manga rumors are starting to pick up some steam after some fan arts of the hypothetical team-up went viral!

While it is going to be a challenge for the manga writers to fit the One Piece characters, especially the Straw Hats in the Attack on Titan universe as the tone of the two manga's are different and that the "power levels" of the universes are huge as well but if the writers of the One Piece x Toriko x Dragon Ball found a way to make those three work in a story then they could do it too with the One Piece, Attack on Titan crossover.

The One Piece, Attack on Titan crossover rumors started on facebook as various users shared some fan art which led to speculations about the crossover.

The most popular theory going about right now is a special episode similar to the "Boss Luffy, Historical Arc" featured in the One Piece anime where the story has nothing to do with One Piece universe but the episode is in an alternate universe.

The story is about the giant zombie "Oars" is attacking a village and it is up to the strawhats and the rest of the Attack on Titan characters to stop him.
