James Gunn has confirmed that *Superman: Man of Tomorrow* won’t just be another Superman vs. Lex Luthor rivalry—it’s shaping up to be something much bigger. According to Gunn, the film will center on Superman and Lex being forced to work together, at least to a certain degree, against a much larger threat looming over Metropolis and possibly the entire world.

This twist flips the classic Superman-Luthor dynamic on its head. Traditionally, Lex is Superman’s greatest nemesis: a genius billionaire who sees the Man of Steel as a danger to humanity. But when a threat arises that even Lex can’t defeat alone, the two enemies may find themselves on the same side—temporarily.

So, who could this “bigger threat” be? DC Comics has no shortage of cosmic and god-like villains capable of pushing Superman to his limits. Darkseid, Brainiac, Mongul, and even Doomsday are all possibilities. Each of them represents a danger so massive that even Lex’s ego might take a back seat to survival.

The idea of Superman and Lex working together opens up intriguing storytelling opportunities. Will Lex truly align with Superman for the greater good, or will he use the situation to manipulate events in his favor? Fans can expect a tense alliance filled with mistrust, strategy, and plenty of moral conflict.

One thing is certain: James Gunn’s *Man of Tomorrow* won’t just be about Superman saving the day. It’s about examining what happens when two of the most iconic figures in DC history—one a beacon of hope, the other a symbol of human ambition and ego—are forced to join forces. And the true question isn’t just *who the bigger threat is*… but whether Superman can trust Lex Luthor when the stakes are higher than ever.
