Tokyo, Japan - Shinjuku District
The Sentinel punched through the window, glass spraying inward as office workers scattered, some diving under desks while others froze in place, their instincts failing them. The robot's targeting system swept the room with precision.
"MUTANT SIGNATURE DETECTED. SURRENDER FOR PROCESSING."
Mariko Yashida rose from her desk, her hand finding the panic button, but she stopped when the Sentinel's weapon arm locked onto a young intern cowering in the corner. The girl pressed herself against the wall, hands shaking so badly she could barely keep them still.
"Onegaishimasu." The girl's Japanese came out in gasps, each word trembling with terror. "I just started here. Last week. Please."
The Sentinel's eye brightened with predatory focus. "MUTANT GENE CONFIRMED. RESISTANCE WILL RESULT IN TERMINATION."
The Yashida family protected their retainers; they always had, for generations, and some oversized robot wasn't changing centuries of tradition.
Mariko slammed the alarm.
Throughout the building, blast doors dropped while emergency lights pulsed in steady rhythm, and in the sub-basements, the Silver Samurai armor began its power-up sequence with a rising mechanical hum.
The wall exploded before she could move, not from the Sentinel but from something else entirely, something that burned with nuclear fire.
Sunfire crashed through, trailing flames that made the air shimmer and warp, his body radiating heat that distorted reality around him as he collided with the Sentinel hard enough to drive it through three walls and out into the Tokyo skyline.
"More are coming! Get out fast!" Sunfire's voice crackled through the heat distortion, urgent and commanding.
More Sentinels descended on Tokyo like something from a nightmare made real, dozens of them blotting out the afternoon sun.
Mumbai, India - Dharavi Slums
Krish's arms worked independently, pounding through a Sentinel's chest while another grabbed civilians and threw them toward safety. Three Sentinels fell in rapid succession, then five more rose to replace them like a hydra growing new heads.
"Bahut zyada hain! (There are too many of them!)" Chakra spun beside him, his shield swallowing attacks and redirecting them back at their sources. "Hum sab jagah ek saath nahin ho sakte! (We cannot be everywhere at once!)"
The density of the slums worked against them; too many people packed into too little space, every collapse killing dozens and every missed shot finding someone's grandmother, child or neighbor. The numbers were impossible and brutal.
A Sentinel tore through a school, and children screamed in voices that cut through everything else, even through the explosions and the chaos and the sound of metal tearing flesh.
Krish blurred, moving faster than he'd ever before as the building shook when he landed between the Sentinel and a classroom where six-year-olds huddled together, too young to understand why robots wanted them dead.
His fist moved with all his strength behind it.
The Sentinel became scrap metal and sparking circuits.
But outside, more advanced units descended, dozens more, with each destroyed unit feeding data to the collective network.
G-One and Chitti Robo fought their own battles across the city, their programming letting them predict Sentinel movements and counter them with finesse, but even they struggled with the sheer numbers pouring in. Mumbai had twenty million people, and the Sentinels didn't care about collateral damage or anything except their programming.
New York City - District X
The shields held, but barely, crackling with energy that threatened to fail at any moment.
Beautiful Dreamer gripped the console, sweat soaking through her shirt as around her the command center hummed with frantic activity and desperate coordination. Screens showed Sentinels hammering the barriers with methodical persistence, testing every weak point.
"North sector's at forty percent!"
"Rerouting auxiliary now!"
Below, the Morlocks fought with everything they had while Callisto's enhanced senses predicted attack patterns and Caliban's tracking identified which robots targeted which civilians, defenders positioning themselves accordingly with split-second timing.
The numbers kept climbing and made victory seem impossible.
A Sentinel broke through on the eastern perimeter, and Sunder met it with a roar that shook windows, struck with enough force to crater pavement and send shockwaves through the ground. The robot sparked and smoked, its chassis crumpling under the impact.
Two more replaced it before the first one hit the ground.
Marrow grabbed one in her bone claws as the robot, heated its plating until the metal glowed red; the bone glowed red too, conducting heat Marrow's body was never meant to handle, and she screamed but didn't let go, drove the machine into the ground with strength born from pure desperation.
Sack tore through another, his massive body scrambling its internal systems with exotic energies, but the plating shifted and reconfigured, blocked his next attempt with adaptive countermeasures.
They learned and got better with each passing second.
A little girl ran into the street, separated from her mother in the chaos, five years old maybe, her mutation letting her change her hair color in rapid succession. Useless in a fight and decorative at best.
A Sentinel locked on her with cold mechanical focus.
Shatter appeared in a blur of motion, scooped up the child and ducked into an alley, breathing hard as his hands trembled from exhaustion and fear. "Don't move, ok? Someone will come for you. I promise."
The girl nodded, crying silent tears that broke Shatter's heart.
Shatter ran back into the fight because hundreds more needed saving and he couldn't afford to think about the ones he'd miss.
Baxter Building - New York
The Sentinel approached Franklin Richards' nursery window with targeting protocols locked and firing sequence initialized.
But it ceased to exist.
Johnny Storm's nova flame melt the robot as the Sentinel went from solid matter to superheated plasma in under a second.
"Touch. My. Nephew. I fucking dare you." Johnny burned white-hot, his body a miniature sun suspended in the air.
More approached, and Johnny met them mid-air with fury that had been building since the invasion, each one that got within a hundred yards experiencing temperatures that didn't exist anywhere on Earth's surface.
Reed Richards operated the building's systems with fluid efficiency, his body stretched across a dozen controls simultaneously, each limb working a different station. "Susan, shield integrity?"
"Ninety-five percent stable." Sue's force fields formed a shimmering dome over the building, invisible but impenetrable. "But if they maintain this assault pattern for another hour Manhattan will..."
"They won't." Reed's voice carried absolute certainty, that came from calculating a thousand variables and seeing only one outcome. "Johnny's handling it."
And he was, the Human Torch carving through the Sentinel swarm like a knife through paper as every robot within a hundred yards died in mechanical agony, circuits frying and plating vaporizing.
Ben Grimm blocked the Yancy Street, his rocky form filling the space as an immovable orange barrier. "Ain't nobody gettin' past me. Not today. Ya hear me?"
Inside Baxter Building's nursery, Alicia held baby Franklin close as he babbled in baby-talk, unaware that killer robots wanted him dead, that his existence threatened people powerful enough to deploy armies. His reality-warping powers could have erased the Sentinels with a thought, rewritten them out of existence, but Jay had limited them for his own protection; now Franklin was just a baby with ordinary vulnerabilities.
His family would protect him with everything they had.
Xavier's School - Westchester
Scott's optic blast carved through three Sentinels in a single sweep, the crimson energy superheating their plating faster than they could adapt. They fell in smoking ruins, then more rose from the tree line like a tide that wouldn't stop.
"We can't hold them!" Bobby's ice slides formed and shattered under energy fire, each one lasting seconds before melting. "There's too many! They just keep coming!"
"We hold the line!" Scott's voice cut through the chaos like a blade, commanding and absolute. "We don't let them reach the students! That's the mission, and we don't fail missions! Not now, not ever!"
Inside, younger mutants huddled together in the reinforced common room, some crying openly, others staring in shock at screens showing the battle, while a few tried to be brave for the others.
Fear showed through anyway, in trembling hands and wide eyes.
In the infirmary, Hank worked with controlled urgency to stabilize the Brotherhood; Magneto remained unconscious despite the combat cocktail in his system, Mystique's breathing came shallow and irregular, Toad had lost too much blood for his healing factor to compensate quickly.
Outside, the Sentinels kept coming in endless waves.
Jean Grey floated above the battlefield, telekinesis holding back a dozen robots simultaneously, invisible hands crushing circuits and bending metal.
A Sentinel broke through the telekinetic barrier, charging toward the front entrance where students were visible through the windows, their faces pressed against the glass.
Kurt Wagner appeared in its path with a BAMF of displaced air, smoke dissipating around him in acrid curls. "Not today, mein Freund."
He teleported with the Sentinel five hundred feet straight up, broke it's thrusters and gravity handled the rest with brutality; the robot slammed into the ground hard enough to crater the lawn and shake the building's foundation.
Kurt's exhaustion showed in every line of his body, sweat pouring down his blue face and staining his costume, his breathing ragged and desperate because teleporting too many times too soon did that.
Stolen content warning: this tale belongs on Royal Road. Report any occurrences elsewhere.
But he saw fifty more Sentinels surrounded the school in a tightening perimeter.
Los Angeles - Sunset Boulevard
The Sentinel smashed through the café's front window as civilians scattered in blind panic, tables and chairs flying like toys while a mutant teenager tried to run on legs that wouldn't cooperate. His power let him change object smell with a touch; utterly useless in a fight.
The Sentinel's weapon charged with a rising whine. "MUTANT IDENTIFIED. CEASE RESISTANCE."
"He's just a kid!" Someone screamed from behind an overturned table, voice cracking with terror. "Jesus Christ, leave him alone! He can't even hurt you!"
The Sentinel didn't care about age or threat assessment beyond genetic markers.
The blast fired.
Surge appeared in crackling blue electricity that lit up the café in strobing flashes, her body absorbing the attack and channeling it through her nervous system; she'd been three blocks away, heard the commotion, ran at superhuman speed that left ozone in her wake.
"Back off, you oversized toaster!" Her hands sparked with stolen energy, bright and dangerous, before she released it in a concentrated burst that fried the Sentinel.
The robot collapsed in a heap of smoking metal.
The teenager stared, his voice shaking with shock and disbelief. "You... you saved me. Why? You don't even know me."
"That's what heroes do, kid." Surge helped him up with surprising gentleness, checking him for injuries with practiced efficiency. "Now get somewhere safe. This isn't over, not by a long shot."
More Sentinels converging on their location as their programming had identified a concentration of mutant signatures worth investigating.
Surge's communicator crackled with other invasion veterans checking in, voices she recognized from New York: Sunspot from Brazil, Armor from Japan, Dust from Afghanistan, all responding to the crisis with the kind of coordination that came from fighting together before.
They'd fought aliens together, saved the world once against impossible odds.
They could do it again, had to do it again, because what other choice was there?
London - Trafalgar Square
The Sentinels spoke in modulated accents that made the situation somehow worse.
"PROCEED TO THE DESIGNATED PROCESSING CENTER. RESISTANCE IS INADVISED."
Processing center, the words making blood run cold in every person who knew their history, who remembered what processing centers meant.
An elderly woman with grey hair stepped forward from the crowd, her mutation letting her see three seconds ahead, helpful for crossing streets safely; she'd lived quietly for decades, never hurt anyone or drew attention.
"I'm eighty-seven years old, you know." Her voice carried clearly despite the tremor, decades of proper elocution training overriding fear. "Never committed a crime in my life. Pay my taxes on time. Volunteer at church every Sunday. So would you mind explaining what exactly I'm being processed for?"
The Sentinel's eye focused with mechanical precision. "MUTANT GENOME DETECTED. REMAND TO CUSTODY FOR RE-EDUCATION AND SOCIETAL REINTEGRATION."
"Re-education." Her voice shook with something between rage and fear, with memories that wouldn't stay buried. "I'm old enough to remember what that meant the first time. My parents fled Germany in '38 because of re-education. I won't go through it again."
The Sentinel advanced with inevitable mechanical certainty. "COOPERATION IS MANDATORY."
Union Jack appeared in a blur of motion, costume bearing fresh scorch marks from recent combat in Manchester; he'd driven back at speeds that would've gotten him arrested under normal circumstances. "Touch that woman and I'll scrap you for parts, mate. Try me."
More British heroes arrived in rapid succession: Spitfire, moving so fast she blurred into afterimages with Excalibur united, their coordination tested but holding together through sheer determination.
The Sentinels kept coming in waves that seemed endless, and across London, the scene repeated like a nightmare on loop: mutants rounded up, humans protesting, robots that didn't care about protests or history or basic human decency.
Washington D.C. - Capitol Building
Senator Kelly stood in his office, watching news feeds as horror crawled up his spine and settled in his gut like lead, as everything he'd worked for twisted into something monstrous.
This wasn't what he'd authorized; nobody had authorized this, nobody in any government position.
His aide burst through the door without knocking, face pale and sweating. "Sir, the President's demanding answers right now. Congress is in emergency session. Everyone's asking who the hell ordered this! The Joint Chiefs are going insane!"
"Nobody ordered this!" Kelly's hands shook as he slammed his desk hard enough to hurt. "The Sentinel program was mothballed years ago! These robots shouldn't even exist!"
But they did exist, hundreds of them, maybe thousands, all attacking simultaneously with military precision that suggested central coordination.
His phone rang with the distinctive tone reserved for the President.
"I don't care whose authorization they're operating under, Senator." The President's voice was steel wrapped in ice. "I want every military asset we have mobilized against them. Right now. This minute."
"Sir, the Joint Chiefs are already reporting in. Our forces are engaging, but the Sentinels are adapting to conventional weapons faster than we can deploy new tactics. Standard arms aren't cutting it."
"Then use unconventional ones. I want every superhero team on this planet called in if we have to. Call the Avengers, call everyone. This ends today."
Both men knew the truth that neither would say aloud; this wasn't ending today.
Xavier's School - Command Center
Xavier's telepathy reached out across impossible distances, coordinating defenses on multiple fronts, but the psychic strain was immense and growing; connecting with X-Men across the grounds while reaching to other teams worldwide, organizing a global response while his own school was under siege and his students were dying.
Blood trickled from his nose in steady streams because he was pushing harder than was safe, harder than was sane.
But what choice did he have when his students were fighting for their lives?
"Professor, you need to rest!" Jean's mental voice carried genuine concern wrapped in fear, projected with enough force to cut through his concentration. "You're going to burn yourself out! Your brain can't take this strain!"
"I will rest when our students are safe, Jean. Not a moment before. Not one second before."
On screens arrayed before him, he watched his X-Men fight with everything they had: Scott's tactical brilliance keeping them alive against impossible odds, Storm's weather manipulation providing cover and devastating offense, Colossus's armored form serving as mobile shield for the younger students.
They were taking damage though, injuries accumulating with each passing minute, exhaustion setting in as powers depleted and bodies failed.
An alert sounded with piercing urgency as twenty more Sentinels approached from the north, flying in perfect formation that suggested military training.
"We can't take another wave, Professor." Hank's voice came through strained, his usual clinical detachment cracking under pressure. "Our defensive systems are at breaking point. Structural integrity is compromised in the east wing."
Xavier closed his eyes, reaching deeper than he ever had before, with the help of Cerebro.
The psychic broadcast went out like a flare across New York, across the country, touching every mind capable of receiving it.
Heroes heard it and answered.
New York City - Streets
Officer Marcus Rodriguez crouched behind his squad car, reloading for the fourth time while bullets sparked off Sentinel armor and did absolutely nothing except waste ammunition.
"This is bullshit!" Chen ducked as an energy blast took out a streetlight above them, showering them in sparks. "Why the hell do we even have guns if they don't work?"
"Focus on evac!" Rodriguez shouted back over the noise. "Just get people to the shelters! That's all we can do!"
People panicked and ran everywhere in blind terror, some toward safety, others directly into danger because fear made people stupid.
A little boy stood frozen in the middle of the street, crying for his mother who was nowhere in sight as the Sentinel pivoted toward him with mechanical precision.
Rodriguez ran without thinking, just grabbed the kid and dove behind concrete as the blast vaporized where they'd been standing seconds before.
"Why?" The kid looked up at him with eyes too young to understand this, face streaked with tears and dust. "Why do the robots wanna hurt us?"
Rodriguez had no answer because he was supposed to protect and serve, but protect against what when robots from nowhere could show up and start killing? When his gun meant nothing and his training meant nothing and all he could do was run and hide like everyone else?
The thought was bitter and shameful and true.
Heroes saved the day while regular people just survived, if they were lucky enough to survive at all.
Mumbai - Rescue Shelter
Fire Chief Rajesh Kapoor organized evacuation with competence born from decades of experience, getting thousands into underground shelters while Sentinels tore through the city above like locusts made of metal.
Shelters had limited capacity though, too many people, not enough space, the math brutal and unforgiving.
"Please, sir, she is hurt. Hamein madad ki zaroorat hai(We need help)." A woman clutched her daughter with desperate strength, both covered in dust and blood that hadn't dried yet.
"Medical team is this way, madam." Kapoor directed them toward triage but he knew the truth; too many injured, not enough doctors, they were triaging based on who could be saved, not who needed help most, letting people die to save others.
His radio crackled with another collapse and more casualties.
He'd been a firefighter twenty years, saved hundreds of lives with his own hands, but watching Krish and Chakra fight outside while he herded civilians to inadequate safety, he felt utterly useless in ways that made him want to scream.
"Kyun, sahab? (Why, sir?)" One of his younger firefighters asked, voice breaking with emotion. "Hamesha kisi ko hamein bachane ki zaroorat kyun hoti hai? Hum khud ko kyun nahin bacha sakte? (Why do we always need someone to save us? Why can we not protect ourselves?)"
Kapoor had no answer that would satisfy, no words that would make it better.
He kept organizing, kept directing, kept doing his job even though it felt meaningless against machines that could level buildings.
Because what else could he do except his job?
Paris - Arc de Triomphe
The Sentinels spoke French with perfect grammar, and the irony wasn't lost on anyone paying attention; this happened in the shadow of a monument to resistance against tyranny.
History repeating itself in the worst possible way.
A street artist stood with others being forced into a group, his mutation letting him make paintings come alive briefly, beautiful and useless for combat.
"C'est mal!" He spoke in rapid French, words tumbling over each other. "You cannot do this! We have rights! Les droits de l'homme!"
"RIGHTS ARE SUSPENDED." The Sentinel's voice was emotionless and absolute. "COOPERATION IS MANDATORY."
"Va te faire foutre avec tes protocoles! (Fuck your protocols!)" Someone threw a bottle from the crowd that shattered harmlessly against metal plating.
The Sentinel's weapon charged with deadly intent.
The wall exploded inward.
Fantomex emerged through smoke and debris, his powers making him appear in three places at once while his guns fired specialized rounds designed for exactly this situation.
The Sentinel adapted and calculated trajectories but not fast enough against someone whose mind was designed to be impossible to predict.
Fantomex's was too slippery to track properly, his bullets finding gaps in armor that shouldn't exist according to the schematics, and by the time the robot figured out which Fantomex was real, it was already too late and falling to pieces.
"Courez!" Fantomex shouted in perfect Parisian French without any accent. "Run! I will hold them here!"
The mutants scattered in every direction while Fantomex stood alone against five Sentinels advancing in coordinated patterns.
He'd fought worse odds before and survived situations that should have killed him.
He'd probably survive this too.
Probably.
Xavier's School - Infirmary
Magneto's eyes snapped open as pain flooded his system like electricity through water: broken ribs grinding against each other, fractured arm screaming in protest, internal bleeding Hank had barely stabilized with emergency surgery.
But he heard the battle raging outside, felt metal in Sentinel construction singing to his magnetic senses even through reinforced walls.
"Eric, absolutely not." Hank moved to restrain him with surprising firmness for someone so gentle. "You're in no condition to even stand, let alone fight. You'll kill yourself."
Magneto's hand rose with trembling effort, and surgical instruments flew across the room in controlled arcs, assembling into a makeshift brace for his injured arm with magnetic precision. "Young mutants are fighting out there, Hank." His voice was hoarse but carried iron determination that wouldn't bend. "They fight because I failed to end this in that submarine. I will not fail them again."
"You can barely stand! Your ribs are broken!"
"Then I shall fight flying."
Magneto floated from the bed with visible effort, powers carrying him despite injuries that would have crippled anyone else as every movement brought fresh agony.
But outside, the X-Men were being hurt, children were dying, and everything he'd fought for was burning.
And he'd be damned to hell itself if he stayed in bed while mutant children fought his battles for him.
He drifted toward the window with growing momentum, looking at the Sentinel swarm through eyes that burned with barely controlled fury as his rage, tempered by pain but no less fierce, crystallized into cold focus.
Time to remind the world why they feared the Master of Magnetism, why his name made governments tremble.
Across The Globe
In S?o Paulo, Sunspot burned through Sentinels with solar fire, his powers enhanced during the invasion letting him operate at levels he'd never imagined possible, hot enough to melt titanium.
In Seoul, the Tiger Division coordinated with local heroes, their Chitauri experience translating remarkably well to fighting adaptive robots with similar tactics.
In Cairo, Dust's sandstorm confused Sentinel sensors while others evacuated civilians from collapsing buildings, her particulate form impossible to target effectively.
In Mexico City, Oya's fire melted robots as she tried desperately not to think about how they looked like bigger, deadlier versions of the aliens from New York that still haunted her nightmares.
In Moscow, the Winter Guard formed defensive lines, scrapping any robot coming their way with brutal efficiency born from decades of fighting super-powered threats.
In Vancouver, Northstar's speed let him evacuate entire blocks before Sentinels could properly target them, moving faster than their tracking systems could compensate for.
In every city, every country, wherever mutants existed, Sentinels appeared like a plague, and wherever Sentinels appeared, heroes fought back with everything they had.
The question echoed everywhere, in every language, in every shelter:
From civilians huddled in basements wondering if they'd see tomorrow.
From police whose weapons meant nothing against metal that shrugged off bullets.
From soldiers whose training meant nothing against machines that learned faster than humans could adapt.
From firefighters who could only rescue, not protect, who could only save a fraction of those who needed saving.
Why do we always need someone to save us?
Why can't we protect ourselves?
Why are we always the collateral damage in someone else's war?
The questions had no good answers, never had, probably never would.
They never did.
