When I do a search for Batman crossovers, I expect the kind of fic with Sora to be in Gotham City about to meet the Caped Crusader himself, because that would be bitching. I certainly don't expect
the only fic with Batman in the summary to wave off the crossover thing with "Riku and Sora as Batman and Superman, go do a bunch of things and stuff."
For one thing: You threw away a potentially awesome "Riku takes up the Caped Crusader's role for an indeterminate amount of time and dwells on his issues" plot for cheap, random humor.
For another: The author also has Kryptonite-laced Furbies with PSTD. And Cabbage Patch kids. And other random things. Is it too much to try and make things make sense?
Finding a reference to Mary Sue just made me more pissed off. Is that normal?
