ACT 1
Mayor Renee Montoya stands at Gotham Square, her voice steady but resolute as she delivers a speech about an ambitious initiative to rebuild Gotham City after the catastrophic events involving The Penguin just three months prior. Her ascent from detective to mayor has been nothing short of extraordinary, though the weight of her city’s darkness feels heavier than ever. As she speaks, she catches glimpses of the crowd—faces scarred by hardship, shadowed by doubt—reminders of the Gotham Montoya has sworn to protect and rebuild.
Among the onlookers is Jaime Reyes, standing with his family, blending into the crowd. Jaime lives his life as a reluctant emissary for The Reach—the creators of the scarab beetle that has changed his life over the course of the past few years, for better or worse. The Reach has positioned Jaime as their intergalactic ambassador, tasked with peacekeeping and diplomacy on Earth. The armor Jaime once used as a superhero known as the Blue Beetle still works, but it’s primarily adapted for ceremonial purposes, and Jaime must constantly try to outsmart the scarab's subtle attempts to manipulate him into serving The Reach’s hidden agendas.
Jaime has been an unlikely ally to Montoya ever since a fateful encounter two years ago, when his Blue Beetle powers manifested during a chaotic museum robbery in Gotham. Jaime had been just a teenager then, scared and overwhelmed, but Montoya’s calm guidance and no-nonsense leadership has helped him navigate the turmoil. Now, as Gotham’s official metahuman liaison, he balances this responsibility with his family’s expectations and the alien scarab’s ever-watchful presence.
Montoya's speech is cut short by a massive explosion that shakes the square to its core. A towering hologram of The Hangmen appears, their leader cloaked in shadow, declaring Gotham’s renewal will begin with its destruction. Panic ensues, and Montoya quickly coordinates an evacuation while Jaime slips away, the scarab already forming his armored suit around him. Together, they fight to protect civilians as the city plunges into chaos.
***
Back at her new subterranean command center beneath City Hall—a futuristic control room buzzing with analog monitors and whirring pneumatics—Montoya assesses the situation. The Hangmen's theatrics are only the beginning. She contacts Jaime, who is patching up injuries and bantering nervously with his scarab about needing a vacation.
Montoya doesn’t mince words. “Jaime, I need you on this. The Hangmen aren’t just after Gotham—they’re after the system. And I can’t fix this city without knowing what we’re up against.”
“Guess that makes me the guy with the alien cheat sheet,” Jaime replies with a nervous grin, but his resolve is clear. Montoya tasks him with recruiting The Guardian, a former operative of Cadmus—a shadowy organization operating on the fringes of legality, known for its cutting-edge but ethically dubious scientific research.
Initially established as a government-backed initiative to safeguard humanity, Cadmus evolved into a morally ambiguous think tank experimenting with genetic engineering, metahuman technology, and weaponized emotions. Their experiments, including attempts to harness raw emotional energy, gave rise to both heroes and tragedies, occasionally resulting in unintended metahuman byproducts. In Gotham, the shadow of Cadmus looms large, its fingerprints hidden in many of the city's greatest tragedies.
Jim Harper, known in the service as The Guardian, once served as a loyal operative for Cadmus before uncovering their dark secrets, leaving him haunted by his role in their experiments. He now specializes in the use of cutting-edge, experimental Cadmus tech, operating in a morally gray area to stop crimes before they happen. After this day's events, Montoya knew that Harper was just the man she needed for this particular job.
***
Meanwhile, in the Narrows of Gotham, a woman named Gabrielle Doe—known to the streets as Halo—has embraced her role as Gotham’s “street angel,” using her powers—tied to a spectrum of emotions, rather than a spectrum of colors—to heal the city’s broken parts while trying to suppress the fractured feelings that fuel her aura. Her unpredictable energy is both a gift and a curse, and the citizens she helps view her with equal parts reverence and fear.
While tracking The Guardian, Jaime crosses paths with Halo during a violent altercation with Hangmen operatives. Her powers flare unpredictably, creating a kaleidoscope of chaos as she struggles to maintain control. Initially at odds, the two quickly realize that The Hangmen are a common enemy. Halo reluctantly joins Jaime, drawn to Montoya’s vision of a better Gotham, though she remains wary of the scarab’s influence.
Working together, Jaime and Halo track The Guardian’s location to a dimly lit Cadmus storage facility, its walls lined with forgotten technology and eerie remnants of the organization's shadowy past. The fluorescent lights buzzed faintly overhead, flickering inconsistently, as Jaime activated his scarab to illuminate the narrow path. As he stepped cautiously inside, the air shifted—a feeling Jaime recognized as his scarab sensing danger. “Stay sharp, Jaime,” the scarab’s voice whispers in his mind, almost teasingly.
From the shadows, a flash of golden light suddenly shoots toward him. Jaime barely activates his energy shield in time to block The Guardian’s assault, the clanging of shield against armor echoing through the cavernous space. “You’re trespassing,” growls the weathered voice of Jim Harper.
Jaime raises his hands defensively, his armor retracting slightly to reveal his face. "Wait, wait! Mayor Montoya sent me—I’m here for you!” Before Jaime can explain further, Halo appears from the opposite side of the room, her aura shifting with a soft yellow glow of uncertainty, making her expression hard to read.
“You two play nice, or I’ll put you both in time-out,” she says, her tone laced with wry humor. Halo doesn't fully trust either of them—one was a Cadmus ghost, and the other had alien tech grafted into his spine—but she could tell they weren’t enemies, either. The scarab’s response to Halo is immediate, detecting the emotional energy radiating from her, and Jaime winces as the scarab whispers, “Unstable anomaly detected. Proceed with caution.” The tension breaks as Halo raises her hands in a gesture of uneasy peace. “I’ve seen enough bad guys for one night. Let’s just... talk.”
Jim Harper, once a symbol of justice, is now a man weighed down by regret. He had been a loyal Cadmus operative until the experiments that created countless metahumans, including Halo herself, shattered his faith in the institution. Plagued by guilt, he left it all behind, retreating into Gotham’s shadows as a pre-crime detective.
Harper immediately feels suspicious of Montoya’s motives, seeing her mayoral administration as just another face of Gotham’s corruption. “A badge and a podium don’t change the game, Mayor,” he growls. But when his premonition tech reveals The Hangmen’s next target—a citywide blackout with catastrophic consequences—he reluctantly agrees to join their cause, spurred by his lingering sense of duty.
***
Later that evening, Montoya confronts The Guardian in the echoing chambers of the subterranean command center. Harper stands rigid, his tarnished shield on his back like a remnant of a war long past. Montoya’s commanding voice fills the room, her mayoral authority clashing against Harper’s seasoned skepticism. “Gotham doesn’t have time for your mistrust, Harper. I need someone who knows how the darkness in this city moves, and you’ve been ahead of it your whole life.”
Harper crosses his arms, his cold, calculating eyes studying her intently. “I don’t work for politicians, Montoya. You get too many clean shoes stepping on muddy streets.”
Montoya steps closer, unfazed by the insult. “You think I don’t know that? I didn’t get here to play politics, Harper. I’m trying to clean up a city that’s been eating itself alive for decades—and I need people who know how deep it goes.”
Harper hesitates, his defenses cracking under the weight of her conviction. “If I help you,” he says, his tone softening just slightly, “I call the shots when we’re in the field. And when this is over, I walk.”
Montoya gives him a wry smile. “Deal. But I’ll hold you to those shots, Harper.”
***
Elsewhere, the leader of The Hangmen, cloaked in shadow, steps forward. It’s Halo’s darker persona, a malevolent reflection of her fractured psyche. This darker side of Halo feeds on the emotional scars of Gotham’s citizens, using their collective despair to fuel her powers and drive her crusade for so-called "justice."
Unaware of Halo’s dual nature, Montoya and her team uncover The Hangmen’s plan to hijack Gotham’s central power grid. Standing atop a crumbling Art Deco skyscraper, they realize they’ve only begun to scratch the surface of their enemy’s reach. The lightning-streaked skyline serves as a haunting and ominous foreshadowing of the battles to come.
***
ACT 2
Halo is nowhere to be found.
Mayor Montoya, Jaime and The Guardian stand deep in Gotham’s industrial district—a sprawl of abandoned factories and skeletal warehouses bathed in a ghostly haze. Montoya is in the lead, her mayoral coat flapping like a cape in the night air, while Jaime's scarab hums faintly, providing dim illumination. The Guardian walks in shadow, his battered shield strapped to his arm like a relic of a forgotten era. Their objective: track down evidence of The Hangmen’s operations.
The three venture into a derelict power plant that The Guardian’s pre-crime tech flagged as a potential base of operations. The interior is a crumbling Art Deco labyrinth, filled with rusted catwalks and eerie murals depicting Gotham's past glories. Here, they stumble upon traces of Halo’s energy—faint, multicolored scorch marks on the walls that shift in intensity depending on the emotional aura of the room.
As they explore, Jaime cracks wise to lighten the mood, his charm clashing with The Guardian’s grim demeanor. Montoya acts as the glue between them, her pragmatic focus keeping the group on task.
***
While searching for clues, the group is ambushed by a gang of thugs. After a brief but cinematic skirmish, in which Jaime’s scarab deploys energy shields and The Guardian uses his tarnished shield with surgical precision, they capture one of the assailants. The thug reluctantly spills a name: Tobias Whale.
Tobias Whale, a once-feared crime lord, is now an older, semi-reformed figure who runs a retro-futuristic speakeasy hidden beneath Gotham’s crumbling public library. The team pays him a visit, descending into his hideout—a smoky, atmospheric den filled with jazz music and sepia-toned lighting. Whale, dressed in a sharp pinstripe suit that reflects his past glory, greets them with a mix of charm and menace.
Tobias reveals that he’s no fan of The Hangmen, as their crusade against corruption threatens what little power he still holds. He offers them information in exchange for protection, hinting that he knows more about Halo’s fractured psyche and the true origins of The Hangmen. Despite their mistrust, the team reluctantly accepts Whale’s guidance, trusting that his wit and encyclopedic knowledge of Gotham’s criminal underworld will help shed new light on the case.
***
Through Whale’s connections, the team uncovers that The Hangmen are planning something massive involving Gotham’s central power grid. As they dig deeper, Tobias provides cryptic insights into Halo’s powers, implying that her emotional fractures were artificially manipulated by someone—or something—operating in Gotham’s shadows.
Their investigation leads them to an underground complex beneath Gotham’s botanical gardens, where they find an abandoned Cadmus lab. Inside, they discover unsettling files indicating that Halo’s aura-based abilities were the result of Cadmus experiments attempting to harness emotional energy as a weapon. Disturbingly, the files hint at a “Subject Zero” who shares a connection with Halo’s darker persona.
As the group begins to piece together answers, the air around them begins to hum with energy. The walls glow faintly with shifting colors, signaling Halo’s presence. They realize too late that they’ve walked into a trap. The room floods with blinding multicolored light as Halo’s darker side emerges, fully embracing her role as the leader of The Hangmen. Her aura fluctuates wildly, creating a surreal, otherworldly effect that warps the very space around them.
“Halo?” Jaime pleads, stepping forward. But the figure before them is no longer the ally they once knew.
With a chilling smile, Halo utters: “You wanted to fix Gotham, didn’t you? Let’s start by breaking it.” Suddenly, a deafening explosion rocks the underground complex, sending debris and energy blasts flying in all directions. The echoes of the explosion fade into silence.

ACT 3
In the smoldering ruins of the abandoned Cadmus lab beneath Gotham’s botanical gardens, Mayor Renee Montoya pulls herself from the wreckage. Battered but resolute, she pulls herself to her feet, her mayoral coat tattered and streaked with soot. Beside her, The Guardian rises, his golden shield dented but still gleaming faintly in the dim light. Tobias Whale stumbles out of the shadows, coughing, his sharp suit now a patchwork of grime and blood.
Jaime Reyes is nowhere to be found. The scarab’s faint energy signature flickers on Montoya’s handheld scanner, leading the group to believe he’s alive but has been taken.
“This city eats its heroes,” Whale growls, lighting a cigarette with shaky hands. “But if you’re still breathing, Mayor, that means we’ve got a fighting chance.”
Montoya narrows her eyes. “Then we fight. Let’s bring Jaime home.”
***
The trio follows the scarab’s signal deep into Gotham’s subterranean layers, navigating through forgotten tunnels, crumbling sewers, and the eerie remnants of Gotham’s abandoned pneumatic transit system. These catacombs are lined with corroded brass fixtures, flickering neon signs advertising long-defunct businesses, and the oppressive weight of history pressing in from every angle.
As Montoya, The Guardian, and Tobias Whale push deeper into Gotham's forgotten transit tunnels, they stumble upon an abandoned chamber dimly lit by eerie, multicolored crystal growths spreading across the walls. The air is thick with a haunting, harmonic wail—a disjointed song emanating from a group of figures at the center of the room. These are The Broken Choir, people warped by Halo’s emotional energy, their eyes glowing faintly as cracks of light spiderweb across their bodies. The Guardian raises his shield instinctively, while Whale mutters, “They’re not alive—not fully, anyway.”
Before Montoya can act, the Choir snaps their heads toward the group in perfect unison, their mournful song shifting into a piercing shriek. They attack, moving with jerky, unnatural precision, forcing the team into a desperate fight. Montoya spots an ancient control panel and, with Whale’s reluctant help, reroutes power to the emergency lights. A sudden flood of harsh, white light disrupts the Choir, causing them to collapse, their glowing energy dimming. Though alive, they remain unconscious, their bodies scarred by the power Halo has unleashed.
As silence falls over the chamber, Montoya studies the fallen victims, her expression grim. “She’s not just breaking Gotham,” she says quietly. “She’s breaking its people.” The group regathers their strength and moves forward, the eerie glow of the crystals serving as a reminder of Halo’s growing threat.
***
The group’s journey leads them to the epicenter of Gotham’s forgotten infrastructure: The Heart of the Machine, a massive, cathedral-like chamber where the city’s old power grid converges. The cavernous chamber is crammed full of futuristic Cadmus technology; it is literally buzzing with energy.
While searching for clues to Halo’s ultimate plan, Montoya stumbles upon a locked archive buried among the circuitry. Guardian’s pre-crime tech enables them to bypass the archive’s defenses, revealing Cadmus records of past experiments.
Among these records is a project dossier detailing the early experiments that fractured Gabrielle Doe’s psyche and unleashed her powers. To Montoya’s shock, Tobias Whale’s name is listed as the financial backer of the research. Further documents reveal that Whale had leveraged Gotham’s underworld resources to fund these experiments in an attempt to create a controllable, emotion-based weapon.
Guardian, visibly angered, confronts Whale, accusing him of being complicit in Halo’s pain. Whale, initially defensive, eventually admits his involvement, though he claims ignorance of the full extent of Cadmus’s experiments. “I thought it was just another job,” he says, his voice heavy with guilt. “By the time I realized what they’d done, it was too late. I’m trying to make it right, but that doesn’t mean I can undo it.”
The revelation leaves Montoya torn. Though disgusted by Whale’s actions, she realizes they can't afford to lose him now. His knowledge of Gotham’s criminal networks—and Cadmus’s secrets—is still vital to their mission.
“You think I’m just a monster?” Whale growls at Montoya as she confronts him. “Monsters don’t get to fix their mistakes. But I’ll die trying, if that means anything.”
Before Montoya can respond, the chamber floods with enemy forces—Hangmen loyalists armed with experimental Cadmus tech. Whale steps forward, his bulky frame shielding Montoya and The Guardian as he unleashes a hidden weapon: a handheld EMP device built into his cigarette case. The resulting blast disables the enemy forces but overloads the chamber’s unstable systems, triggering a chain reaction. Whale shoves Montoya and The Guardian toward safety, staying behind to hold off reinforcements.
“Go!” he shouts, his voice echoing through the collapsing chamber. “Gotham’s yours now!”
Montoya and The Guardian barely escape as the chamber collapses and Whale’s silhouette disappears slowly into the rubble.
***
Now alone, Montoya and The Guardian follow the scarab’s signal to its source: a sprawling underground arena that looks like a grotesque mix of advanced technology and raw, emotional energy. At its center stands Halo, her fractured aura casting shifting, kaleidoscopic shadows across the walls. Jaime is suspended in mid-air, trapped within a sphere of pulsating light, his scarab seemingly deactivated.
Halo’s darker persona speaks with a voice that echoes unnaturally: “You see now, don’t you? Emotions are the true power of this city—its rage, its fear, its despair. I will harness it and reshape Gotham into what it was always meant to be.”
Montoya steps forward, her voice cutting through the chaos. “This isn’t you, Gabrielle. Gotham doesn’t need a god—it needs people who fight for it, flaws and all.”
A battle unfolds within the vast underground arena, its walls pulsating with distorted light emanating from Halo’s fractured aura. Halo, cloaked in her kaleidoscopic aura, stands atop a platform, her voice reverberating as her darker persona speaks of reshaping Gotham with the raw power of its collective despair. Montoya and The Guardian enter cautiously, their resolve unshaken despite the oppressive atmosphere and Halo’s overwhelming power. As the ground trembles with each pulse of energy, The Guardian’s pre-crime tech activates, helping him anticipate Halo’s volatile attacks and shield Montoya from harm.
Montoya quickly identifies a network of conduits connecting Halo’s platform to the energy sphere trapping Jaime. While The Guardian keeps Halo distracted with precise, calculated strikes, Montoya moves toward the conduits, using her expertise in tactical analysis to disrupt their power flow. The task is grueling, as the arena reacts violently to her interference—crystals of energy shatter around her, and bursts of raw emotion manifest as physical force. With persistence, she manages to sever one of the primary conduits, weakening the sphere enough for Jaime’s scarab to reactivate.
With his powers partially restored, Jaime breaks free of the sphere in a burst of blue light, immediately joining the fight. Together, the trio coordinates their efforts: The Guardian deflects Halo’s attacks, Montoya disables the remaining conduits, and Jaime confronts Halo directly, using the scarab’s technology to stabilize her powers. The combined effort forces Halo’s darker persona into retreat, leaving Gabrielle’s true self momentarily exposed.
As Halo’s darker persona falters, Jaime and Montoya work together to reach the human side of Gabrielle, appealing to her sense of hope. For a moment, the aura dims, and Gabrielle’s true self emerges, horrified by the destruction she’s caused.
Gabrielle, struggling to hold her unstable powers in check: “This is the only way... I can’t let it consume me, or Gotham. I won’t let my darkness hurt anyone else.”Jaime (desperately): “Gabrielle, no! We can figure this out together. The scarab—I can stabilize you—just give me more time!”Gabrielle, a bittersweet smile breaking through her pain: “You’ve already given me more time than I deserved, Jaime. You gave me hope. You and Montoya—both of you—you reminded me who I am.”Montoya (firmly, fighting back tears): “Gabrielle, don’t do this. You’ve fought too hard to let it end here. We don’t leave people behind—not in this city, not ever.”Gabrielle (softly): “I’ll always be here, Renee—Gotham’s light, even in its darkest shadows.”
Ultimately the darker side refuses to let go. In a final act of defiance, it unleashes a catastrophic surge of energy, threatening to destroy everyone in the arena. Gabrielle, with tears streaming down her face, makes the ultimate sacrifice: she absorbs the energy into her body. As her aura intensifies, Gabrielle reaches out to Jaime and Montoya one last time before unleashing her power in a brilliant, blinding wave—neutralizing the threat but sacrificing herself in the process, imploding in a burst of light that leaves the arena eerily silent.
***
EPILOGUE: THE NEXT MORNING
Mayor Montoya stands before a crowd in Gotham Square, delivering another speech. The scars from Halo’s rampage and the battle in the Heart of the Machine are still visible, but so are signs of rebuilding—a testament to Gotham’s resilience. This time, the mayor's words carry the weight of loss but also a renewed determination.
Montoya’s speech is both a eulogy and a call to action. She begins by honoring the sacrifices made during the fight, including the ultimate price paid by Tobias Whale. “Tobias Whale was not a perfect man,” she says, her voice steady but heartfelt. “He made mistakes—grave ones—but in his final hours, he chose to stand on the right side of history. He fought to save this city when it mattered most, and for that, Gotham owes him its gratitude. His name will remind us that redemption is possible, even in the darkest hearts.”
Young Jaime Reyes, now more confident in his role, watches from the crowd alongside The Guardian, whose tarnished shield has been restored to its former glory.
Montoya shifts her focus to the city's future, emphasizing that the battle against corruption, despair, and fear isn’t over. “Gotham is no stranger to darkness,” she says. “But today, we stand at a threshold—a chance to build something new, something better. I promise you this: no more backroom deals, no more neglect of the people who call this city home. Together, we’ll create a Gotham where hope shines brighter than fear—a Gotham where every voice matters, and every life is valued.”
Montoya concludes by urging Gotham’s citizens to take part in the rebuilding process, stressing the importance of unity and collective responsibility. Her words resonate with the crowd, and for the first time in a long time, Gotham feels a spark of hope. The scene closes on Montoya, looking out over the city she’s vowed to protect—not as a perfect leader, but as one who understands its flaws and still believes in its potential. Her determination, paired with the resilience of Gotham’s people, sets the tone for a new era.
On the horizon, a single, faint halo of light hovering in the sky, a subtle reminder that even in darkness, hope endures.
