8 Most Embarrassing Fights Between Batman And Superman

7. Smart Batman Versus Dumb Superman

Batman frequently uses Kryptonite to put himself on an equal footing with Superman from a physical standpoint, but he once tried to even the odds by using a device to make himself super intelligent and the Man of Steel really, really dumb. In fact, Superman was pretty much taken back to his "Caveman Days" while Batman used his new noggin to travel into a future with similarly smart egghead types for him to hang out with. There were a lot of weird time travel antics in this one, but it all wrapped up with them both being returned to normal and not really acknowledging the fact that Batman had just made his best friend mentally impaired (they also failed to address why exactly being made super dumb caused the Kryptonian hero to suddenly grow a beard). Of all the fallings out these two have had, this quarrel was easily one of their most bizarre.
