Welcome to this small Multiversal story that I've had the pleasure of creating! I was honored to be invited by Aragorn_ II _Elessar to contribute to their "When Legends Meet" series. If you're unfamiliar with their work, I highly recommend checking out the incredible story "Heroes Coming Together"—a fantastic multi-fandom crossover that weaves together universes like Buffy the Vampire Slayer, The Arrowverse, Star Wars, and many more.
In this short fan fiction, I explore the unique collision of two distinct movie universes: Sonic the Hedgehog and Resident Evil. The story unfolds as a consequence of the Singularity—the cataclysmic event at the end of The Flash Season 1—which rippled across the multiverse with consequences far greater than anyone foresaw. The resulting cracks between realities have given rise to new and unexpected interactions between heroes and worlds.
I want to extend a heartfelt thank you to Aragorn for giving me the chance to bring this idea to life and for allowing me to play within the Multiversal sandbox they've built. This is both an exciting challenge and a ton of fun, and I hope you'll enjoy reading it as much as I've enjoyed writing it.
So, let's dive in, shall we?
When Legends Meet: Speed Meets Survival
Prologue: The Singularity
It began on Earth-1, within the halls of S.T.A.R. Labs. A tear in the very fabric of space-time erupted—what began as a small anomaly became a raging Singularity, threatening to consume everything. The resulting shockwaves rippled across the multiverse, shattering barriers between worlds and realities. Heroes and villains alike, unaware of each other's existence, were now on a collision course. Chaos had begun, and the multiverse would never be the same again.
Earth-91581
What should have been a warm, beautiful day in Green Hills, Montana was anything but normal. The normally tranquil town, surrounded by lush green trees and rolling mountains, was under attack.
Doctor Robotnik, the bald, genius mastermind with a wildly unique mustache, had harnessed the immense power of the Master Emerald to build a monstrous, towering robot—a mechanical colossus in his own image. The massive machine loomed menacingly over Green Hills, its steps shaking the ground and spreading chaos as its shadow stretched across the town.
High in the sky, against the backdrop of a brilliant blue horizon, a red biplane—the Tornado—cut through the clouds like a streak of defiance. Aboard were Sonic the Hedgehog, Knuckles the Echidna, and their steadfast pilot, Miles "Tails" Prower.
The trio soared toward the towering menace, their resolve unwavering. Robotnik wasn't just threatening to reduce Green Hills to ruins—he was aiming for far more. If left unchecked, the entire world, perhaps even the universe or multiverse, would bow to Robotnik's will.
"How are we supposed to beat this thing?" Tails asked, his voice tinged with uncertainty as the massive robot grew larger with every second.
Perched on the left wing of the Tornado, Sonic turned to his friend, his face set with determined confidence.
"We need a plan," Sonic replied. He glanced over to Knuckles, who stood stoically on the right wing, his sharp gaze fixed on the towering mech.
"Knuckles, use your strength to—"
Before Sonic could finish, Knuckles had already made up his mind. Without a word, he crossed his arms over his chest, took a step back, and dropped off the plane, freefalling toward the treetops below.
"Jump off the plane… Wow. Okay," Sonic muttered with sarcasm, watching Knuckles disappear into the green below.
Tails glanced back at Sonic from the cockpit, equally confused.
Sonic sighed, shaking his head as he turned his attention back to the giant robot ahead. The Tornado continued its path toward Robotnik's mechanical monstrosity, the metal behemoth growing larger and more menacing as they closed the distance.
"Alright, this is what we're gonna do," Sonic began, climbing and standing up on the top wing of the Tornado, carefully steadying himself.
"Step one: light taunting," Sonic declared confidently. "Step two: I have no idea!"
Meanwhile, down on the ground near the Mean Bean Coffee Shop, Tom and Maddie Wachowski stood amidst the mess and chaos. Like many Green Hills residents, they watched the red biplane streak across the sky, heading straight for Robotnik's colossal mech.
"Sonic!" Maddie called out with slight worry in her tone.
Tom stood beside her, his gaze fixed on the Tornado as it pushed forward. The tension in the air was palpable, but beneath the concern on their faces, there was a flicker of hope.
As the Tornado circled the colossal mechanical menace, something strange began to take form high above the sky. A sudden bright flash of light tore through the clear blue, and from it, a swirling wormhole emerged, pulsating with energy.
Sonic, now standing confidently on the top wing of the plane and ready to fire off his usual taunts toward Robotnik, froze mid-thought. His confident smirk faltered, replaced by a look of shock.
"Wait—what the heck is that?!" Sonic shouted, his voice rising with genuine confusion.
Hearing the hedgehog's alarm, Tails instinctively glanced upward. His gloved hands gripped the controls of the Tornado tightly, trying to keep the biplane steady even as his curiosity got the better of him.
"That looks like… some kind of wormhole!" the young fox called out, his voice a mix of wonder and concern. Multitasking wasn't new to him, but flying while watching an interdimensional anomaly appear? That was pushing it.
Sonic continued staring upward, his expression shifting to slight horror. He hadn't known Tails for very long—only a few days, really—but he had already learned to trust the fox's instincts. If Tails thought this was a wormhole, then it probably was. And that couldn't be good.
Tails made a quick call, determination laced in his voice.
"I need to get a better look at this!"
With that, the Tornado banked sharply to the left. Sonic dropped into a low crouch, gripping the top wing tightly as the wind whipped against him.
Meanwhile, deep within the control center of the enormous robot, housed in the dome-like structure of the robot's head, Doctor Robotnik stood tall, arms raised like a conductor orchestrating chaos. Bolts of green lightning surged around him, the unmistakable energy of the Master Emerald flowing through his very being.
The mad genius smirked triumphantly as the robot mirrored his movements, tethered to him by the sheer force of will and the Emerald's power. But then, on one of the large projection screens surrounding him, something new caught his eye—a swirling wormhole now forming high above them.
Robotnik turned his head upward, his gaze narrowing with intrigue.
"Well, well…" Robotnik murmured, his voice dripping with fascination.
Nearby, seated at a cluttered control panel, Agent Stone was trying to make sense of the robot's overwhelming systems. His brow furrowed in frustration, but then he too noticed the wormhole on the projections.
"Uh, Doctor?" Stone said, his voice wavering. He blinked in slight horror. "What… is that? That doesn't look good."
Robotnik ignored Stone entirely, captivated by the sight. His gloved hand reached out, as if trying to grasp the swirling anomaly on the projection screen.
"Oh, it's magnificent," Robotnik whispered to himself, his grin widening. The man was practically giddy with curiosity. "An unexpected variable! A gift from the universe itself. What secrets are you hiding?"
Stone looked from the projections to Robotnik, clearly unnerved by the doctor's unsettling fascination.
"Secrets? Doctor, I don't think we want to know what that thing is."
Robotnik chuckled darkly, still staring at the wormhole with a glint of madness in his eyes.
"Oh, Stone," he said smoothly, his voice dripping with condescension, "I always want to know."
Near the Mean Bean Coffee Shop, Tom and Maddie stood frozen, their eyes locked on the anomaly as it pulsed with unearthly light. Both were speechless, their expressions a mixture of awe and deep concern.
Further down the broken street, Commander Walters of G.U.N., accompanied by several operatives, stood in shock. Their focus had shifted entirely from Robotnik's rampaging mech to the swirling rift above. Walter's face was pale with disbelief.
"My God…" Walters muttered under his breath, barely audible.
The citizens of Green Hills, who moments earlier were scrambling to find safety from Robotnik's chaos, now stopped in their tracks. Their fear turned to uneasy curiosity as they craned their necks to take in the strange spectacle in the sky.
Among the crowd, Wade Whipple, Green Hills' bumbling but well-meaning deputy sheriff, gawked with his mouth hanging open. He blinked a few times, trying to process what he was seeing.
"Uh… That… That's not normal, right?" Wade stammered to no one in particular, his voice cracking slightly.
A few blocks away, Knuckles was in his element, tearing through Robotnik's droids with raw, unrelenting power. Each punch sent sparks flying, gears clattering, and scrap metal littering the streets.
With a final, crushing uppercut, Knuckles shattered another droid, its remains scattering across the pavement.
But then… he froze.
A faint hum pulsed through the air—a sound that didn't belong. Knuckles' sharp instincts kicked in as he turned his gaze skyward, narrowing his purple eyes at the swirling wormhole above.
"This…" Knuckles growled, his voice low and certain. "This is no trick of Robotnik. It's something far worse."
Earth-121775
The static-filled voice of a man crackled across the emergency frequency, his words distant and hollow, echoing through the once-sterile halls of the Arcadia.
"This is Arcadia, broadcasting live on the emergency frequen—"
A sharp click silenced the man's message. The frequency wavered for only a moment before a clear, calm voice replaced it—her voice.
Alice.
"I say we live up to the promise."
Her words, steady and resolute, cut through the silence as she gripped the microphone, her fingers smudged with dirt and dried blood.
"This is Arcadia, broadcasting on the emergency frequency," Alice continued, her voice firm but not unkind. "Location: 118.03 degrees west, 34.05 degrees north. There is no infection. Repeat, there is no infection. We offer safety, security, food, and shelter."
She leaned closer to the mic, as if to push her words across the vast emptiness of a broken world.
"If you are out there… we will help you. There is hope."
With a final click, the broadcast ended.
The small room fell into silence, save for the hum of the Arcadia's systems. Alice set the microphone down carefully, her movements deliberate. Her expression remained hard, her shoulders squared like a soldier refusing to falter.
Promises didn't always mean salvation. She knew that better than anyone.
Stepping away from the control console, Alice pushed open the heavy metal door and headed to the survivors on the top deck.
Earth-121775 was a dying world. It wasn't always this way—once, it had been familiar, thriving, much like any other version of Earth. But everything changed when Umbrella Corporation unleashed the T-Virus, a biological weapon masquerading as a cure.
The virus spread faster than anyone could have anticipated, infecting not just people but animals, ecosystems, the very fabric of life itself. Within months, cities fell. Governments crumbled. Humanity's last strongholds were overrun, their streets flooded with the ravenous undead.
Civilization became myth. Survival became war.
The Arcadia, a massive cargo freighter turned sanctuary, was one of the few places left untouched—at least for now.
Alice stepped onto the deck, her boots clanking against the metal floor. She glanced around. Survivors, dressed in stark white clothes, milled about—silent, lost, ghosts of what they once were. Their hollow eyes betrayed their exhaustion, their disbelief that a place like this, free from infection, could even exist.
By the railing, Chris Redfield leaned against the metal bar, arms crossed, his gaze locked on the endless ocean stretching to the gray horizon. Beside him, Claire Redfield stood quietly. She turned when Alice approached.
"You think anyone heard it?" Claire asked, her voice steady but tinged with doubt.
Alice stopped beside her, resting her hands on the railing as her eyes scanned the darkening horizon.
"Maybe," Alice replied, her tone clipped. "It doesn't matter. If even one person is still out there, they deserve to know there's somewhere safe."
Chris pushed himself away from the railing, walking up to join them.
"We've done all we can here," he added, glancing at the survivors. "They're safe. For now."
Alice's expression didn't soften.
"Safe doesn't last long in this world," Alice admitted somberly, her voice carrying the weight of hard truths.
Chris exhaled slowly, shaking his head as he leaned against the railing, his eyes scanning the endless, lifeless horizon. The ocean stretched as far as the eye could see, a grim reminder of how much the world had lost.
"Hard to believe there's anything left out there…" he muttered, his tone heavy with doubt.
Claire turned to look at him, her brows furrowed.
"There has to be," she remarked.
But before Alice could respond, a low hum reverberated through the air. It was faint at first, a distant vibration that made the metal deck shiver beneath their feet. The three of them froze instinctively, the calm broken. Alice's sharp instincts flared to life as she scanned the horizon.
"Did you hear that?" Chris asked, straightening as he looked around.
"Yeah," Alice said, her voice clipped. She squinted at the horizon—her eyes narrowing as the air itself seemed to shift and ripple.
Then it appeared.
A pulse of light flickered across the deck, faint at first—like a spark on the edge of vision. The air seemed to vibrate, a deep hum reverberating through the Arcadia's metal frame. Alice's head snapped up instinctively, her sharp gaze searching for the source.
"What was that?" Chris asked, frowning as he looked around.
Claire turned toward the horizon, her brow furrowing.
"It's… coming from the sky," she said.
And then they saw it.
High above the Arcadia, the clouds twisted and churned. A swirling wormhole began to form, spinning like a vortex against the lifeless grey sky.
Alice's eyes narrowed, her instincts flaring as every muscle in her body tensed.
"What the hell is that?" Chris said, the disbelief thick in his voice. He took a step forward, squinting upward, as though the act of seeing it clearly might somehow explain its existence.
Claire took an involuntary step back, clutching the railing, her voice wavering.
"Is that Umbrella's doing?" she asked.
Alice didn't answer. Her mind raced, cataloging everything she'd seen, everything she knew—and none of it matched what hovered in the sky above them. This wasn't Umbrella. It wasn't natural. It was something else.
The survivors on deck began to notice it, their hushed conversations falling silent one by one as they turned their eyes upward. Murmurs spread through the group, tinged with unease.
Alice stared at the swirling vortex, her expression hardened, unshaken despite the unnatural sight. Her voice, low and edged with grim determination, cut through the tension like a blade.
"You survive one nightmare… and the world throws another at you."
She exhaled slowly, her fists clenching at her sides as the hum of the wormhole vibrated through the air.
And she knew, deep down, that whatever this was… it was only the beginning of something new.
In Los Angeles, Luther West stepped out of the sewer tunnel, his boots splashing softly in a shallow puddle. The air was cold and sharp, a stark contrast to the suffocating darkness he'd left behind. Battered but alive, he wiped the grime from his face and trudged forward, shoulders squared, refusing to look back.
Then he froze.
A faint hum thrummed through the air, unnatural and unsettling. Luther's eyes lifted to the sky, and there it was—a wormhole, swirling violently, a jagged tear in the grey clouds above.
He stared, wide-eyed, his voice low and confused.
"What the hell is that…?"
The hum of the aircraft engines filled the cabin, a low growl of power. Jill Valentine walked steadily down the narrow aisle, her boots striking the metal floor in perfect rhythm. Flanked on either side were rows of Umbrella soldiers, clad in black tactical gear, their weapons primed and ready.
Her face was cold, emotionless—her body under the control of the gleaming red and silver scarab device embedded in her chest. A light pulsed from it, a cruel reminder of Umbrella's iron grip.
"Deployment in T-minus 57 seconds," Jill announced, her voice clipped and precise. "When you hit the deck, you watch your formation. No prisoners. Shoot to kill. Total enemy numbers are unknown but will include Umbrella fugitives and prime targets: Claire Redfield, Chris Redfield, and Project Alice."
She paused, turning slowly on her heel to walk back.
"So people, whatever is waiting for you out there, just know one thing—"
Suddenly, the plane shook violently, cutting her off. Jill grabbed the overhead support bar with one hand, keeping her balance as the soldiers shifted uncomfortably.
"What was that?" she snapped, her tone unshaken.
One of the pilots pointed frantically toward the window of the cockpit. Jill strode forward, brushing past them to look through the cockpit glass.
Her steely eyes narrowed as she stared at the swirling wormhole glowing ominously against the darkened sky. The unnatural sight reflected faintly in the glass, its pulse sending a faint vibration through the plane.
The red scarab embedded on Jill's chest flickered, as though responding to the anomaly with a faint hum of energy. Jill tilted her head slightly, her expression calm but sharpened by curiosity.
"Interesting…" Jill muttered.
The scarab on Jill's chest flared with a pulse of red light. Her body stiffened for a split second, and then her eyes—once clear and cold—shifted. The pale blue irises dimmed, replaced by the sharp glow of the Umbrella symbol.
The world around Jill changed.
The cabin of the plane bled into shades of crimson. Everything Jill saw was outlined in red. A hum of distant energy buzzed faintly in her ears as the interface appeared in her vision.
Umbrella Prime – Active Protocols
Subject: Unknown Singularity Detected
Jill's field of view zoomed in, her sight sharpening as lines of data scrolled at the edges of her vision, analysing the swirling vortex outside the window. It loomed in the darkened sky, a spiraling tear of violet and electric blue, pulsing like a beating heart.
At the bottom of her interface, a box blinked to life. It grew, flickering faintly, before resolving into the face of The Red Queen—a girl's face, eerily pale and framed with red light. Her digital eyes were cold, calculating, and entirely unfeeling.
"Anomaly detected."
The voice was sharp, British, and devoid of humanity, a perfect mirror of the AI's expressionless gaze. The hum of data processing grew louder, the scarab on Jill's chest pulsing in rhythm.
"Energy signature… unknown. Dimensional tear detected."
The Red Queen's face tilted ever so slightly, her expression neutral as streams of data flashed through the display. Lines of numbers calculated and recalculated, the AI's efforts to make sense of the impossible falling short. The anomaly resisted classification.
"Source undetermined. Threat level—unable to quantify."
The scarab on Jill's chest flared brighter, a thin whine of energy vibrating against her sternum. The Red Queen turned her gaze directly to Jill, her crimson eyes unblinking and sharp.
"Priority: maintain mission focus."
Jill stood still, a perfect instrument of control. She didn't flinch as the Red Queen continued, her voice colder now, more commanding.
"Targets remain: Claire Redfield, Chris Redfield, and Project Alice. The Singularity is to be monitored. Proceed. The mission will not be compromised."
Jill's eyes blinked once—slow, deliberate—and when they opened, the digital overlays receded, leaving only the faint red glow of the insignia burning in her irises.
"Understood," Jill said, her voice devoid of anything human.
That's the prologue done folks!
The singularity wormhole appears during the climactic battle against Robotnik in Sonic the Hedgehog 2 (2022), while simultaneously showing up at the end of Resident Evil: Afterlife (2010) and the beginning of Resident Evil: Retribution (2012).
A fun fact about the Earth numbers: these are subtle Easter Eggs referencing the birthdates of two of the films' top stars!
Sonic's Earth is based on Ben Schwartz's birthdate: September 15, 1981 (Earth-220).
The Resident Evil Earth reflects Milla Jovovich's birthdate: December 17, 1975 (Earth-202).
I'm currently working on the next chapter of this crossover, as well as my Kingdom Hearts x Sonic story. I hope to have a chapter ready in the next few days.
Thank you all for the continued support, and a huge shoutout to Aragorn _II_ Elessar for allowing me to bring this idea to life for their series.
Stay tuned—there's more to come!
