Hello everyone, this is my first post on the site, so I figured I'd do a little theory to for my first post. In the Batman vs Superman trailer we see a scene in which Batman, Superman, and Wonder Woman fighting something BIG. And some theories and rumors said that could be Doomsday, but those have been debunked by a editor on the film. My theory is that it's none other than Lex Luthor.
I say that it's Lex because of a recent image that has submerged online. In a post on November 24th to the site ComicBook.com, it shows a picture of a 3-pack toy that features Batman (in his armored suit), Superman, and Lex Luthor, but this Lex Luthor toy isn't just Lex in a nice suit, have a look for yourself.
Yep, it's Lex in his mega-armor, and I say that's Lex not just because of the toy, but because it possibly who could be in the big final fight. Lex does play a big in the movie, manipulating both Batman and Superman, and somewhere in the film, the two will work together and become partners, it's that reason that could cause Lex to put on his armor and go after Superman and Batman, and Wonder Woman helps out too (though I haven't really come up for a reason as to why she would stop Luthor). You're all probably wondering what could give me this idea besides the toy. Well, that would be the scene in the Batman vs Superman trailer that involves Batman zooming out of the way of a laser-beam.
I say this because in some movies that involve a giant robot suit, it has these things, most of the time: a rocket launcher, flight, a HUD display, invulnerability to head on attacks, and laser-beams. And as seen with the toy Lex has a rocket launcher. Now for the laser-beam, I believe that the laser-beam will show when Lex runs out of rockets and the four barrels come together to make one barrel that become a laser-beam, another belief I have is that the laser-beam can come out of his chest through a detachable chest plate, like with Mecha-Godzilla 2, or he could have a laser-cannon on his back that fires on big laser.
