This is an aged-up, quirkless AU, which will follow the Bloodshot movie closely up until the end, where it will diverge significantly.
For anyone interested, the song mentioned throughout the story is called "Psycho Killer" by Talking Heads, and if you havent seen Bloodshot, it might be worth listening to so you can get the vibe.
"Go for comms, Delta Two. Sitrep."
"Ain't looking good, LT. Soup sandwich in here. Four hostages down. Looks like they interrogated them and dumped the bodies here. Echo Two, give me a sitrep."
"No sign of alpha target. Moving location."
First Sergeant Midoriya Izuku stalks silently through the back alleys of Mombasa, Iran, rifle up. He pauses at the backdoor of a rundown building, taking note of the targets inside, and relays the info over the channel.
"Contact, building two, ground floor."
He pounds twice on the door and quickly steps aside as its shredded by dozens of rounds of ammo. Midoriya plucks a grenade from his vest and tosses it through the opening left by gunfire, just as a command is issued over his comms-
"Bravo Six, hold on breach."
Boom. Too late.
"Roger that. Breaching now."
Midoriya moves quickly but efficiently, dispatching the four remaining hostiles as his Lieutenant scrambles to accommodate.
"Delta, Echo, hustle. Double time. Bravo's on location… Bravo Six! I said hold on breach!"
Midoriya continues through the building, eliminating two more men when he hears the ceiling creak in the silence left behind. There. He slinks up the staircase, swiftly reloading his ammo before taking out three more men. He tosses a tear gas canister in front of him to clear out any remaining and to obscure his entrance into the living quarters on the second floor. As he steps into the room, he is met with a disturbing sight, but one he is unfortunately not unaccustomed to. A man known to them by his alias, Stain, is standing in the middle of the room, tall, scarred, with wild black hair tied back by a red bandana. He is holding his gun to the head of their primary objective, a teenage girl with dirty silver hair, sitting stock still, eyes terrified and hopeless. This is Aizawa Eri, the daughter of a high ranking official in the secret service.
"Drop your gun," Stain demands. When Midoriya fails to immediately comply, he repeats, "I said, drop your gun!" Which he punctuates by thrusting the muzzle further into Eri's skull.
Midoriya does a brief but thorough scan of the room, noting only an abundance of half-empty bottles of alcohol, and an old landline phone on his left, before moving to obey.
"All right. Take it easy… What do you want?"
"Helicopter. Now-" Stain's bloodshot eyes shift nervously.
Over his radio, Midoriya hears a comrade, "On location. Building two."
"-And tell them to Back! Off!"
Midoriya does. "Alpha One, stand down. We got this situation handled."
"Rodger that. Holding."
Stain is high-strung and distracted. Time to make his move.
"If you want a helicopter, you gotta give me a phone." His right hand drops subtly down by his holstered pistol.
"There." Stain bobs his head to his right.
Midoriya glances briefly around as though looking for the proffered phone.
"Where?"
"There." And when Stain moves his gun off Eri's head for a split second to gesture towards the phone Midoriya noted when he entered, he's ready.
He fires.
A grateful tear leaks out of Eri's scarlet eye, and Midoriya's team sweeps through the building behind him, relaying the scene to Lieutenant Kamihara.
"Bravo Six in sight. Alpha target secure."
By the time their plane finally touches down in Italy, Midoriya is more than ready to get away from his teammates, as much as he loves them. His impulsive solo entrance has been the punchline of almost every sentence uttered by his friends.
As they load the plane for take off:
"One of you guys wanna give me a hand with this?" Midoriya requests.
"Why? You're practically a one-man army." Tsu jests in with her typical deadpan expression. Kirishima cackles, but trots over to help him anyway.
On their way home:
"Hey Shoji, can you grab me a water— oh. Never mind. Midoriya's already halfway there." Jirou deadpans. Midoriya rolls his eyes at their antics, but doesn't say anything knowing he has a (well-earned) reputation for impulsivity.
When they arrive:
Midoriya can hear Kirishima exuberantly proclaiming his manliness to their mutual friend Kaminari, who was unable to accompany them due to a last-minute injury. The blonde shoots him two thumbs up jokingly.
Before he can make his escape, the group bands together one last time as they do after every mission.
"No mission too difficult, no sacrifice too great!" Midoriya shouts.
"Duty first!" His teammates reply with equal passion.
After depositing his gear, he heads out of the hangar where he catches a sight that makes his heart jump and he shakes his head in gratitude and disbelief at how lucky he is. His wife is leaning against their olive green convertible wearing a white sundress; her honey-brown hair loose and glistening in the evening sun as she waits for him. Her bangs flutter against her rosy cheeks as she offers him a coy smile, before it breaks into bubbly laughter as he jogs up to her and she jumps into his arms. He spins her around, breathing in the scent of her strawberry shampoo before setting her down, gazing into her milk chocolate eyes, and kissing her. She runs her soft hands through his bushy (and sweaty) forrest hair before pulling away. He whispers, "Ochako." She replies, "I missed you."
They ride with the top down towards their home on the Amalfi coast, enjoying the breeze and the company. They spend the evening strolling around the busy pier, hand in hand, listening to the seabirds and each other, as they recount their days apart. They dance on the beach outside their apartment, moonlight reflecting the passion in each other's eyes. They retire to their bed.
Midoriya Izuku rises with the dawn, but rises alone. A note left by Ochako on their nightstand tells him she went to get them breakfast and will be back soon. Midoriya goes to the bathroom, washes his face, and is preparing shave when he hears the floorboards creak in the hallway outside their apartment door.
"Baby?"
He turns the water off and steps aside. A dart crashes into the mirror where his image was reflected towards the door and three men enter in a misguided attempt to subdue him. He grabs the arm of the first man and smashes it against the wall, making it release its weapon. He throws the second man into the shower while he grapples with the third. As the second man flails in his grip, Midoriya throttles the first man unconscious and when he falls, Midoriya grabs one of the darts embedded in the mirror and dispatches the second man he was holding. The third one stumbles out of the shower and punches Midoriya in the chin, which has little effect.
"Oh no-"
The second man barely has time to finish his lament before Midoriya throws him down over the toilet, shattering the porcelain and a few of the man's bones in the process.
"Ochako…" Midoriya breaths as he charges out of their apartment, but nearly runs over a man as he rounds the corner to the hallway.
"What's your problem?!" The stranger yells from his newfound position on the floor.
Midoriya elects to ignore him and continue in his search for his wife when he is hit by a sudden wave of dizziness. His muscles go limp, and he crashes gracelessly to the floor. As his eyes begin to close unwillingly, he catches a shock of faded blue hair and a pasty hand holding a syringe, as the man from the floor strolls up to his limp form.
"You all right, friend?" A sarcastic voice intones.
Darkness.
As his senses return slowly to him, Midoriya notes hazily that his vision is obscured by a sackcloth bag and also that he is freezing. He hears footsteps next to him before the bag is roughly removed. He shifts his hands but quickly realizes that his wrists and ankles are bound securely to the metal chair he is sitting on and that the chair itself is bolted to the floor. A quick glance around places him in a meat locker. Comforting. But before he has the opportunity to perform a more thorough sweep of the room, a door at the far end swings open. A vaguely familiar face enters. The man from the hallway. He dons a heavy black parka to match his socks-with-sandals clad feet, while the man guarding Midoriya fiddles with a radio on the table next to him. A low thrum echoes around the room and the blue-haired man begins to bop. Midoriya stares, stunned and mildly concerned, as his captor dances down the hallway to the music…
"I can't seem to face up to the facts.
I'm tense and nervous and I can't relax.
I can't sleep cause my bed's on fire.
Don't touch me; I'm a real live wire…"
The chorus sounds as the man gets up in Midoriya's face, lip-synching the words.
"Psycho Killer…"
The creep shuffles over to the radio and turns it down while Midoriya eyes him warily.
"Never gets old."
"Who are you?" Midoriya finally asks the question that's been on his mind the whole time.
"Who am I? I'm the guy that ruined your vacation. Name's Shigaraki Tomura. So, that's one for you. Now one for me. Who tipped you off about the hostages in Mombasa?"
Midoriya shifts in his seat but remains quiet.
"Right. I thought you might clam up. That's why I brought a little extra motivation."
The newly named Shigaraki whistles and a man with a gruesome scar running down his forehead drags a chair forward to rest in front of Midoriya. He also sets what looks to be an air compressor next to it, twisting it on.
"Well, look who it is," Shigaraki chuckles, and Midoriya's heart stops as two men drag Ochako into the room. She's gagged, mascara running, and hair a tangled mess, her light pink blouse torn and dirty. She looks scared, but her eyes flicker with lingering fire as she visibly tries to pull herself together for his sake.
The men shove her down in the chair before him, and Midoriya scrambles for something to say, anything, to get her out of this.
"She has nothing to do with this."
"Once again then, who tipped you off?" Shigaraki demands.
"I don't know, man. That's not my job. I go where they point me."
Visibly frustrated, Shigaraki grabs the bolt gun attached to the end of the hose on the compressor and squeezes the handle, shooting a sharpened stake out the end. A thinly veiled threat. He takes a step toward Ochako, grinning at Midoriya.
"Hey, look at me," Midoriya growls desperately.
Shigaraki ignores him, pressing the end of the nozzle against Ochako's temple. She trembles slightly.
"Look at me!" He yells desperately. The man's manic red eyes flicker towards him, one finger tapping against the handle teasingly.
"I don't— I can't answer cause I don't know. If I knew, I would tell you! I don't know! You could ask me anything, anything else, but this I can't tell you cause I don't know!"
Midoriya's heart feels like it's about to explode while Shigaraki seems to consider his response.
"…Yeah, I believe you." He pulls Ochako's gag down and steps away. Midoriya releases a breath he didn't know he was holding.
"Izu-" Ochako gasps, "Izuku."
"It's gonna be okay," He tries his best to reassure her.
His eyes catch a smirk on Shigaraki's chapped lips as the man turns back to Ochako. He scratches his neck awkwardly, and, voice tainted with false sympathy, intones, "Bad news, baby. It's not gonna be okay."
Midoriya's heart plummets. "NO!"
Ochako straightens up, sticking her chin up bravely and smiling at him, and Shigaraki moves swiftly and efficiently.
"…Psycho Killer…" the music haunts the silence.
Shigaraki drops the bolt gun, the clang breaking Midoriya's eyes away from his wife's limp body. He locks eyes with her murderer and jolts, straining every muscle in attempt to free himself and avenger her.
"Oh, you're nothing." His emerald eyes seem to glow in the dim lighting, promising retribution.
"You don't even exist anymore. I swear, I will find you and end you!… You should kill me now, cause you won't have a second chance."
Shigaraki Tomura purses his lips, nodding in thought and finally clicks the radio off. He pulls a pistol from his parka and the cold barrel lands between Midoriya's eyes.
"Thanks for the advice."
Boom.
