Zak's Crossoverse gripes: - Some franchises in any massive Crossover uses are can fit poorly in a setting where everything that People mixes are put into a singular universe - sometimes make little to no sense - mary Sue OCs

other gripes with Fan-made Crossovers: - when Characters are portrayed just like their canon selves, this can cripple a crossover between Main anime of Pokemon(at least before retires Ash and Pikachu) and the Adventure series of Digimon with everything else that isn't stuff like K-on! - Source Material's scrappiness can keep me from making anything I use too close to official canon - Pooh's adventures youtube video series - some people use our world(at least it's official canon) as catch-all representative for M-rated medium in their crossovers
