The climax of James Gunn’s 2025 Superman film centers on a catastrophic split of Metropolis itself—literally divided in half by a trans-dimensional rift that Lex Luthor detonates to draw out and defeat Superman. This isn’t a traditional fistfight across a city block; it’s an existential threat to the city’s physical continuity, forcing Superman and his allies to confront not only a powerful doppelgänger but also the structural collapse of their world. The scene functions as both spectacle and metaphor, turning Superman’s greatest strength—his connection to Metropolis and its people—into the very weapon being used against him.
Luthor’s plan operates on multiple levels, each designed to overwhelm Superman through different vectors of threat. Rather than simply engineering a more powerful opponent, Luthor combines his resources with stolen genetic material, creating Ultraman as a clone of Superman while simultaneously weaponizing dimensional technology and recruiting additional threats like The Engineer and the mystical Hammer of Boravia. This layered approach means Superman cannot win through raw power alone; he needs strategy, allies, and ultimately a fundamental reconfiguration of how he understands his role in protecting the city.

How Lex Luthor’s Plan Actually Works in the Climax
Lex Luthor, portrayed by Nicholas Hoult, bases his entire strategy on a deceptively simple premise: he has Superman’s DNA. Using stolen Superman hair, Luthor cultivates Ultraman—a clone that possesses all of Superman’s powers but none of his values or restraint. This approach represents Luthor’s philosophical position that Superman himself is the problem; given identical power, a being without Superman’s moral framework becomes unstoppable force. Ultraman serves as the proof of concept for Luthor’s worldview.
The trans-dimensional rift itself operates as a second weapon, equally critical to Luthor’s success. By splitting Metropolis into two halves separated by dimensional space, Luthor forces Superman into an impossible situation: protect one half of the city while the other collapses into an alternate dimension, or attempt to save both and be drawn away from the core conflict. This structure mirrors classic Superman dilemmas but operates at a civilization-ending scale. The rift isn’t incidental to the climax; it’s the strategic centerpiece that makes defeat possible.
The Cascading Threats Superman Must Face Simultaneously
Superman doesn’t face Ultraman in isolation during the climax. The Engineer—a separate metahuman threat of considerable power—enters the conflict alongside Ultraman, creating a multi-front war. Additionally, the Hammer of Boravia, a mystical artifact, introduces a threat that operates outside Superman’s normal frame of reference. Combined, these three elements (Ultraman the physical/psychological mirror, The Engineer as raw metahuman power, and the Hammer as something genuinely alien to Superman’s experience) represent a more sophisticated threat design than simply creating a stronger opponent.
A critical limitation in Superman’s arsenal emerges here: raw strength becomes insufficient. Superman cannot punch his way through dimensional rifts or mystical weapons. The climax essentially forces Superman to rely on elements he typically minimizes—tactics, preparation, and most importantly, his relationships with other heroes. This represents a deliberate constraint on Superman’s power set, ensuring the climax demands something beyond his Kryptonian abilities. Without this constraint, the scene would collapse into a straightforward power-scaling contest, which would undercut everything Gunn’s film builds about Superman’s actual role in the world.
How Mister Terrific Becomes the Key to Reversing the Rift
Mister Terrific, played by Edi Gathegi, emerges as the crucial element in resolving the climax—not Superman alone. While Superman engages Ultraman and The Engineer, Mister Terrific uses his technological and intellectual abilities to reverse the trans-dimensional rift. This division of labor redefines what “saving the day” means; it’s not about the most powerful person winning, but about different heroes contributing their specialized expertise.
Mister Terrific’s role reveals a practical limitation in Superman’s approach: he cannot solve every problem through direct action. Dimensional physics, technological systems, and strategic coordination require different skill sets than those Superman possesses. By making Mister Terrific’s actions essential to the climax, Gunn signals that Superman operates most effectively as part of a team rather than as a solo hero. The reversal of the rift through technological means rather than brute force also shifts the climax’s resolution away from the typical superhero destructive spectacle toward something more methodical and intellectual.
The Physical Scarring of Metropolis as Climax Consequence
After Mister Terrific reverses the rift, Metropolis is reassembled—but not perfectly. The city emerges with a literal scar running through its center, a permanent mark of Luthor’s attack. This detail matters because it refuses the easy narrative where the hero’s victory restores everything to normal. Instead, the scar represents lasting damage, visible trauma that persists long after the immediate threat ends.
The imperfect reassembly creates a comparison point with traditional Superman narratives: previous films and comics often show cities returning to pristine condition after Superman’s victories, rendering the threat abstract and consequence-free. Here, Metropolis bears a visible wound. This wound serves both narrative and thematic purposes—it reminds the audience that dimensional rifts tearing a city in half cannot be casually reversed, and it sets up the post-credits sequences where Superman and Mister Terrific acknowledge the failure of their repair work. The scar becomes a permanent feature of Metropolis’s geography, a reminder that even superhero victories carry costs.
Character Arcs Converging in the Climactic Conflict
Superman, portrayed by David Corenswet, enters the climax having already established his connection to Metropolis and his understanding of what it means to protect it. But Ultraman represents a version of Superman with power but without that ethical foundation—a Superman who does what he wants rather than what’s needed. The conflict between Superman and Ultraman therefore operates as an internal conflict externalized: Superman fighting against the version of himself he could become if he ever abandoned his values.
This character-level conflict prevents the climax from devolving into pure spectacle. Yes, there are dimensional rifts and stolen artifacts, but the core battle is ideological. Superman must defeat Ultraman not because Ultraman is stronger (they share identical powers) but because Superman’s will is stronger, his purpose clearer, and his connection to others deeper. The presence of Mister Terrific, The Engineer as a secondary threat, and the Hammer of Boravia complicates this philosophical confrontation with practical obstacles, but they never overshadow the central question: which vision of Superman—the clone or the original—will define the outcome?.
The Lex Luthor Paradox and His Ultimate Miscalculation
Nicholas Hoult’s Lex Luthor enters the climax convinced that creating Ultraman proves his fundamental thesis: Superman is dangerous not because of who he is, but because of what he is. A Kryptonian with godlike power inevitably becomes a threat. But the climax proves Luthor wrong in the most direct way possible. Ultraman, possessing identical power, becomes a worse threat precisely because he lacks Superman’s values. Luthor’s plan inadvertently demonstrates that Superman’s character is not incidental to his power—it’s foundational.
This represents a significant limitation in Luthor’s strategic thinking. He assumes that power determines outcome, when the climax reveals that philosophy, relationships, and character determine outcome. Luthor’s miscalculation isn’t tactical; it’s epistemological. He doesn’t understand what actually makes Superman effective. The very weapon Luthor creates—Ultraman—becomes evidence against Luthor’s worldview rather than evidence for it. When Ultraman fails where Superman succeeds, Luthor’s ideological framework collapses.
Post-Credits Sequences and the Enduring Scar
In the post-credits sequences, Krypto appears in space, establishing that Superman isn’t alone even on a cosmic scale. The scene affirms that Superman’s core characteristic—his ability to form relationships and inspire loyalty—extends beyond the human realm. But more directly relevant to the climax’s aftermath is the exchange between Superman and Mister Terrific regarding Metropolis’s reassembly. Superman critiques the imperfect nature of the city’s restoration, acknowledging that their solution, while successful, remains fundamentally incomplete.
The scar running through Metropolis stands as physical testament to this incompleteness. Unlike earlier Superman narratives where the hero’s victory is clean and total, Gunn’s climax and its aftermath accept that some damage cannot be fully repaired. Metropolis will heal, but it will bear marks of what happened to it. This acceptance of partial victory and lasting consequences reframes what heroism means in this universe—not the elimination of all evidence of conflict, but the prevention of total destruction and the commitment to rebuild, however imperfectly.
