If anything you're just furthering the point that none of the Disney or potentially FF villains are worth Sora's time because he's clearly dealing with these way more powerful bs original villains.
...which is true since all the FF and Disney villains are confined to their worlds and the KH villains are pretty much set on conquering and/or destroying all the worlds. As I've said I would have not continued on with supporting the series (bought every game bar final mixes) if KH2, and to a certain extend CoM, didn't change the direction of the series to a more unique experience rather than just being a simple fairytale-story-like crossover.
