The only thing worth mentioning is that a lot of, if not all those other over TV shows and movies are considered separate continuities/timelines, so while it most definitely is responsible for everything in its own show, it's not necessarily responsible for the villains in other Scooby-Doo-related works. Even so, it certainly doesn't change the fact that it's the most evil character by a very large margin from any entry in the franchise (at least to my knowledge).
