The first theory pertains to the Snyderverse as a whole, suggesting it offers a more realistic or cynical take on a world with superheroes. For instance, in this universe, Batman uses guns to kill, and Superman harbors significant self-doubt. Some speculate that the ultimate goal was to depict an Injustice-style world, where an evil Superman takes over. Multiple visions in "Batman vs. Superman" and the Snyder Cut of "Justice League" hint at this possibility. This might also explain some criticisms directed at the universe, as it could have led to alternate versions of characters from a hopeful universe intervening in this world.
In "Wonder Woman," Diana confronts Dr. Maru, also known as Dr. Poison, who creates a gas giving superhuman strength and speed. Diana defeats the enhanced General Ludendorff, but this might be the beginning of something larger. A theory suggests it was a precursor to the venom drug famously used by Bane. Dr. Maru survives the encounter, potentially allowing her to develop the drug further.
When Ben Affleck's Batman is shown as comfortable with killing, fans questioned why the Joker remains alive. One intriguing theory is that the Joker is actually Jason Todd, who, instead of dying, was driven into insanity and turned into the Joker. This twist could add depth to Batman's failure and intensify their rivalry, given the Joker’s potential training under Batman.
Additionally, some fans propose Christopher Reeve’s Superman costume from 1978 has a pragmatic reason for having red trunks over the suit, speculating that Martha Kent only used the Kryptonian blanket for the trunks because they are indestructible.
These theories continue to spark discussions among fans, connecting various elements across movies, TV shows, and comics. What are your favorite fan theories? Share them in the comments.
