Equestria Girls are kinda magicalMore Like This
EQG is like Elseworlds. Sure sometimes Batman is a cowboy vampire pirate, but not really.
If you really fall in love with Gay Vampire Pirate Cowboy Batman, its okay. You can write fanfic, draw fanart, cosplay, and tell yourself (and anyone who will listen) that somewhere out in Universe 683492 Apple, Batman is swinging from a bonaventure mizzen with a stetson and a Winchester rifle, drinking the blood of brooding young men with pouty lips and exceptionally smooth legs.
If you hate Vampire Cowboy Robot Mormon Batman you can pretend it never happen and stick to the regular comics series where he's just a time traveling caveman.
