The Flash: 10 Ways Ben Affleck's Batman Could Be Written Out Of The DCEU

Moving forward, Henry Cavill is expected to make cameo/supporting appearances in a number of upcoming DC movies, and there's no reason to suspect that The Flash won't be one of them. In the Flashpoint comic book, the Man of Steel was kept hidden in an underground bunker by the U.S. government after his rocket crashed into Metropolis rather than Smallville.

Emaciated and unsure how to use his powers, this timid Superman eventually escaped and caused chaos, so what if Affleck's Batman joins the Fastest Man Alive on his journey through the Multiverse and ends up having to battle Kal-El...again.

Now knowing that Superman is a hero, we're sure Batman would try to convince him of his potential, and it would be undeniably heartbreaking to see the Dark Knight ultimately fall in battle with this deranged Superman, especially if he does that to protect Barry and give him enough time to travel to another part of the Multiverse, sadly, without him.
