not to shit on decade old ffn fics but in being nostalgic i've noticed there are a lot of young justice x dcau crossovers from when yj seasons 1-2 were airing that seem like they were written by someone who has never seen a dcau show. like, they're explicitly said by the author to be the dcau. not just any generic justice league, but the dcau (sometimes even specifying around what episode / season!), but there's stuff that directly contradicts dcau canon.

like, the flash will be barry allen, despite the fact that in the dcau the flash is wally west. nine times out of ten, there's some kind of exchange about batman not having a robin and rejecting the idea that he would ever take on a protege, despite the fact that by the jl animated series, dcau batman has two robins and a batgirl. if zatanna is involved, the jl usually says that they don't know her / she doesn't exist, and sometimes this is even said by batman and its like.. bruce! yes you do know her!! you've known her for years!

like i love the concept, i wish there were more dcau x yj crossovers, especially with a s1 yj team (or a yj team a year or so after s1), but a lot of the ones that exist feel like the author watched all of young justice (at the time) but only like. season one of justice league.
