Superman: Unbound

Lois Lane volunteers to be a hostage, drawing Supergirl and the captors into a tense standoff above the city. The rescue test becomes a conversation about visibility, trust, and what it means for a public figure to be tied to a secret life. Lois pushes forward with curiosity about making Superman's civilian identity public, risking everything for honesty.

A staff meeting at the Daily Planet interrupts their plans, and Clark is pulled away by the unsettling beacon of a meteor. Lois voices the deeper dilemma of privacy versus the risks of public disclosure in the face of danger. The couple must weigh how much of their relationship should remain private in a world that demands transparency.

Superman swoops in and destroys the destructive drone before the city can be harmed. He retrieves its beacon and transports it to the Fortress of Solitude for analysis, hoping to uncover who is pulling the strings. The find points toward a mastermind with grand, dangerous ambitions.

The beacon points to Brainiac, a Coluan scientist inhabiting a formidable mechanized form. He orchestrates a flood of drones and catalogues civilizations as data to be preserved. This revelation makes the threat personal for Earth and its heroes.

Supergirl recalls Brainiac's capture and miniaturization of Kandor, Krypton's capital, an event that Kryptonians have never fully recovered from. Her parents had tried to stop him, but contact with Krypton's world was lost. The fear that Earth could suffer the same fate deepens the resolve to confront Brainiac.

Superman embarks on a galaxy-spanning chase to locate Brainiac's drone network, piloting a Kryptonian craft across the cosmos. He watches as Brainiac's drones strike another planet, seize its capital, and threaten to collapse the skies into a blazing sun. He is briefly unconscious aboard Brainiac's ship, among a chamber full of bottled cities.

Inside Kandor, Superman's strength wanes under the artificial red sun, yet he reunites with Zor-El and Alura. They reveal Brainiac's directive: learn all there is to know, destroy civilizations so knowledge cannot grow, and preserve it in a static snapshot. This insight fortifies a plan to strike Brainiac by reclaiming Kandor.

Superman escapes Kandor using subjugator robots and wrests Kandor from Brainiac's grasp, bringing it back into Earth's sphere. The move sets the stage for a decisive confrontation on home soil. Kandor's return rebalances Krypton's legacy on Earth and fuels the final stand.

Lois, informed by Supergirl, warns the Pentagon of Brainiac's invasion threat. The alert prompts military preparations as Brainiac's ship returns and his drones descend on Metropolis. The city braces for a coordinated, high-stakes defense.

Brainiac's drones descend on Metropolis and encase the city in a crystalline bottle. The protectors scramble to respond, but their efforts are overwhelmed by the comprehensive containment. The siege creates a clockwork tension as hope hangs in the balance.

Superman and Supergirl are captured by Brainiac's forces and subjected to a brutal mind-onslaught designed to drain his humanity. The threat of annihilation hangs over Earth, raising the stakes for every survivor. Yet Superman's resolve remains steadfast, fueled by Kara's support.

Superman and Supergirl confront Brainiac in a tense exchange about what Earth means to him, aiming to thwart the plan to unleash a Solar-Aggressor on the Sun. Their dialogue sharpens the moral stakes and reframes power as responsibility. The clash moves toward a decisive, planet-saving confrontation.

The duel shifts into a swamp, where chaos fights against control in a monumental showdown. After sustained effort, Brainiac combusts, ending his threat and allowing Metropolis to begin its recovery. Kandor is restored to its rightful scale, and Krypton begins a new colony to rebuild its legacy.

In a quiet, decisive moment, Clark Kent publicly confirms his relationship with Lois Lane and offers a marriage proposal. The scene signals a new era for their personal lives and their roles as public figures who stand together openly. Their union fortifies the bond between truth-teller and truth-seeker.

The post-credits scene highlights Brainiac's power glowing within the Fortress of Solitude, suggesting remnants of his influence linger. It hints that future challenges could arise from the mysteries Brainiac left behind. The team remains vigilant as a new era begins for Earth and Krypton.
