[Mild SPOILERS for Batman v Superman ahead.]

-

Warner Bros. will take over Hall H at Comic-Con International 2015 to present a peek into the future of the studio's DC movie universe, beginning with Batman v Superman: Dawn of Justice. It has already been revealed that a good chunk of the main cast (along with director Zack Snyder) should be there, but WB may still has plenty of surprises up its sleeve to take Comic-Con by storm.

Several new still images from Batman v Superman have been released, revealing several key scenes from the movie. Among them were an encounter between Diana Prince (Gal Gadot) and Bruce Wayne (Ben Affleck), Lex Luthor (Jesse Eisenberg) with either long hair or a very bad wig, and and (of course) Henry Cavill back as the Man of Steel. Perhaps the most intriguing of these pics was the one from the big showdown between Batman and Superman, featuring the two facing off head-to-head.

In that same article from EW, some more details were revealed of that fight, including Batman's motivation and the means he uses to bring Superman to his level. Their description of the scene confirms that Batman does indeed use Kryptonite to weaken Superman:

If you’re going toe-to-toe with the son of Jor-El, you better come correct. For his climactic rooftop brawl with Superman, Batman outfits himself with a reinforced mech-suit equipped with strength-augmenting armor and, yes, kryptonite. The design resembles the one used for the confrontation between these two in Frank Miller’s The Dark Knight Returns.

In the graphic novel (and animated DC movie) this Batman v Superman fight is clearly taking inspiration from, The Dark Knight Returns, Superman was infected with Kryptonite before the two duked it out, making the playing-field more even for Batman. While we have yet to see how Kryptonite works in the DC movie universe, we already got a look into the effects Krypton's atmosphere has on Kal-El in Man of Steel, which made him a lot weaker than usual. It would probably be safe to assume the same holds true here.

Batman v Superman - Kryptonite confirmed

As we have discussed in the past, there are various ways that Kryptonite can be used by the Dark Knight, such as Kryptonite gas, a Kryptonite ring, or outright Kryptonite impalement. A previous rumor said that Batman would be using a “Kryptonite-laced spear," but there is always the possibility that Snyder could get a little more creative with his implementation of Superman's weakness.

As further evidence of Dark Knight Returns' influence on Batman v Superman, check out these scene details/descriptions for the film (from EW):

- Bruce Wayne (Ben Affleck) and his loyal butler, Alfred (Jeremy Irons), are gravely intoning their lines into a burned-out fireplace, as Bruce prepares for his Valley of Elah moment with Superman. The billionaire vigilante appears weary but determined, not unlike the actor portraying him.

- In his editing suite in Pasadena last month, Snyder showed off early passes of the money sequence, a rainy rooftop battle between the two capes. There’s an undeniable thrill to watching these pop culture icons go at it–throwing each other through walls and skylights.

- Snyder also reveals a scene in the Batcave where Bruce Wayne outlines his motivations to a skeptical Alfred, a bit of realpolitik reasoning that weighs the morality of a preemptive strike on Superman against even the minimal chance of humanity’s destruction.

EW also interviewed Snyder about Batman v Superman, where the director revealed what the original plan was for the Man of Steel sequel (before Batman entered the picture):

I remember talking about 'What's the next villain? We can't do another alien invasion.' Brainiac was definitely down the road. Metallo, I think, was going to be the main bad guy of this movie.

Of course, that leaves the potential for the two villains mentioned above, Brainiac and Metallo, to appear down the line. EW has also confirmed that Oscar-winner Chris Terrio (who rewrote David S. Goyer's initial Batman v Superman script draft) has completed the script for Justice League Part One, which is set for release in late 2017. That means that Snyder and Terrio already know for certain if either of those super-powered antagonists will be part of the first Justice League film.

A while ago, it was rumored that Brainiac will be the villain of the first Justice League movie, after Batman and Superman start working together. It's unlikely that any further light will be shed on that matter at SDCC 2015, though speculation is still rampant that WB and DC will use the event to introduce the new Green Lantern(s) featured in Justice League Part 1. Until then, however, we're left speculating about what WB/DC has in store for the Hall H crowd.
