5. Barry Allen Dies

Flash Death

Ok, we may be getting ahead of ourselves again here, but the fact that The Flash is one of only a few superheroes to stay dead for years rather than just weeks or months is definitely significant and may give us an idea of how his story could play out on the big screen.

During a famous DC Comics event known as “Crisis on Infinite Earths”, Barry foils the plan of a villain known as the Anti-Monitor to destroy the Earth with an anti-matter cannon by creating a speed vortex to draw the power in which wipes him away in the process. This is where the “Speed Force” comes in as that’s said to be the source of The Flash’s powers.

The vaguely defined extra-dimensional energy force also provides others with his abilities (we’ll get to that a little later), so if Snyder does decide to kill off a hero in the second Justice League movie, someone else could take over!
