Justice League vs. The Fatal Five and Batman & Harley Quinn have both been deemed canon by Bruce Timm, and by it's references to the previous serieses.
But THEY are considered canon by Bruce Timm and mentioning of events of the previous DCAU canon, even as far as going to reference that one line in Batman Beyond Return of The Joker of the new Arkham building
But why? If this is the DCAU wiki shouldn't all DCAU content be included?
Then why are the other movies included such as Batman Beyond Return of The Joker, Mystery Of The Batwoman, etc?
