I read the One Piece x Toriko manga. I like how the anime made a plot out of it, but I really enjoyed that last scene where they all meet, which wasn't in the anime.
I've read two of the three Romance Dawn versions, and also a bit of One Piece Green. Strong World 0 should be the best of the other stuff. Then there's also some other warly versions I think, and there's definetely One Piece x Dragon Ball. Also those Log Book stuff and then Chopperman. Damn lot of side-stuff. Gonna read it all, cause it's One Piece!
