Because of its open-source nature (in its later iterations), thousands of fans have used Mugen to create crossovers that official companies could never license. One Piece Mugen V9 is not an official game by Bandai Namco or Toei Animation; rather, it is a carefully curated “build” – a compilation of hundreds of fan-made characters, stages, and music tracks packaged into a single, playable game.
