The anticipation for James Gunn’s Superman: Man of Tomorrow continues to grow. New details have surfaced about the film’s mysterious villain, adding to the excitement. After Superman’s success earlier this year, fans are eager to see how James Gunn expands the DCU’s mythology in the sequel.
Interestingly, a new casting report may have revealed the first clue about who Superman and Lex Luthor will face next. Although unconfirmed, the report strongly hints at one of DC’s most iconic villains — a foe powerful enough to challenge the Man of Tomorrow himself.
Man of Tomorrow Villain Description Sparks Speculation
According to Nexus Point News, the film’s villain will require heavy prosthetics and makeup, and the studio is focusing on actors with strong builds and imposing stature. This description immediately supports long-running fan speculation that Brainiac might be the movie’s main antagonist.
Moreover, Brainiac’s live-action appearance would naturally demand extensive prosthetic work, given his green skin, technological design, and cosmic origins.
Why Brainiac Fits the Man of Tomorrow Story
Brainiac, known as one of Superman’s most intelligent and dangerous foes, has long been rumored to appear in the DCU. Early reports suggested that David Corenswet’s Superman and Nicholas Hoult’s Lex Luthor would team up to face a shared enemy. This rare alliance instantly fueled theories that Brainiac’s threat is large enough to unite both hero and villain.
Furthermore, James Gunn intensified these rumors when he posted an image of the finished Superman 2 script, featuring a cross-section of a human brain on its cover—a clear nod to Brainiac’s name and identity.
Could Mongul Be the Villain Instead?
While Brainiac appears to be the strongest contender, the report’s description also matches another major DC villain: Mongul. Known as a Warzoon tyrant and ruler of Warworld, Mongul’s massive scale and prosthetic-heavy design would fit perfectly with the casting details.
Additionally, his sheer power could justify an alliance between Superman and Lex Luthor. Since Mongul often challenges the Justice League itself, his inclusion would mark a massive escalation in the DCU’s cosmic stakes.
Man of Tomorrow Sets Up DCU’s Next Major Threat
Although official confirmation is still pending, the evidence strongly points to Brainiac or Mongul as the DCU’s next great adversary. Both villains would test Superman’s strength and morals while expanding the scope of James Gunn’s growing universe.
Given Gunn’s storytelling style, fans can expect an emotional, action-packed sequel that balances spectacle with humanity. Man of Tomorrow is set to release on July 9, 2027, and will likely redefine how Superman stories are told in modern cinema.
