If Batman and Spider-Man switched rogues galleries none of their villains would last more than ten minutes against the new enemy
Batman takes down all of Spider-Man’s villains with ruthless efficiency and preparation
Batman’s villains are all like “TAKE ME SERIOUSLY DAMMIT” and Spider-Man is like “No 😜”
The Joker would have an intense hatred for Spider-Man because Spider-Man is actually funny
That was the exact thought process behind this post
its canon (shown in jokers return) that joker can in fact not handle people being funnier than him especially at his expense
