Hello, hello! I'm just a typical One Piece fan, who's been viewing these boards in anonymity for a while and now I finally got a username. One of the threads I frequently visit is the 4Kids discussion, because you guys come up with such hysterical theories on how the dub could be butchered.
The thing I like about One Piece would probably be Oda's style, because of its pure awesomeness and the fact that it doesn't look anything like "normal" anime. The characters are so well-developed too, and it's easy to like the villains as much as the good guys.
