(WARNING: POTENTIAL SPOILERS FOR BvS: Dawn of Justice, TREAD LIGHTY)
So after seeing the awesome trailer for Batman v Superman (here it is if you haven't sen it)
There's an interesting part that caught my eye, that could change the movie forever...Doomsday
And If you didn't know, Doomsday has killed Superman in the comics and an animated movie (Superman: Doomsday). There was even a novel called The Death and Life of Superman.
So Doomsday made an appearance in the trailer, and the Trinity is fighting against him. But what if something terrible happened, what if Superman....died at the end of Batman v Superman?
The Actual Theory
So we know that they end up fighting Doomsday at the end, and its a big aftermath, with the whole giant explosion and Supes' flying through rubble. What if the aftermath is just an effect of the death of Superman? If that happens, DC could do something so amazing, it would kick Marvel right in the ass. Lets take a look at DC's upcoming slate:
Ignore the stuff in the bottom row because we wont be using that. You can see from this handy chart that the JLA movie is split into 2 parts. Some would think it's because DC wants to reel in more money but what if it's because there won't be a specific "boy scout" in the first movie? What if they killed Superman in Batman v Superman, Doomsday dies along with him, Batman and Wonder Woman form a team in honor of Superman in JLA Part 1, and Superman rises again at the end. Leaving the second part to more pressing matters *cough*Darkseid*cough*. The only proof I have of this theory is that Ben Affleck and Gal Gadot were confirmed for JLA P1 while Henry Cavil is only expected to go along with them. Otherwise I might be totally wrong and just wasted an hour writing this out.
Batman v Superman: Dawn of Justice will release on March 25th 2016.
