In His Corner

Summary:

Jason Todd survived cages, corners, and a childhood where love was real but never enough to keep the lights on or his dad out of jail.

When Bruce Wayne enters his life, Jason trains hard, sleeps soft, and counts every kindness as something he’ll owe later.

Somewhere between caring for his addicted mother, bruises, training mats, and bought intimacy, something fragile begins to form between them.

Notes:

Hi and welcome! 👋
If you’re here: thank you for giving this fic a chance.

Quick heads-up: I don’t actually know a whole lot about MMA. I’ve recently fallen down the rabbit hole of watching Oktagon, and somewhere along the way my brain went, “Okay, but what if Jason Todd - no cape, no vigilante - was a rough underground MMA fighter instead?”
And once that thought took hold, this story kind of wrote itself. If something isn’t 100% technically acurat or realistic, that’s on me and I hope the story makes up for it.

The fic is already well underway (40+ chapters written but still in need of proof reading and fine tuning), and I’m planning to finish it at around 50 chapters total. Updates will likely be twice a week, barring real-life chaos.

Thanks again for being here. I hope you enjoy stepping into Jason’s corner with me.

🥊💙

Chapter Text

The warehouse had once been a textile mill. You could still see the outlines of old machinery on the walls, the ghosts of bolts and pulleys. But recently the place had been reborn, dressed up in the cheapest glamour money could buy.

Colored spotlights sliced through the haze of smoke and dust, turning the cracked concrete floor into something almost theatrical. Girls in sequined bras and skirts the size of napkins wove through the aisles with trays, balancing bottles of whiskey and rum in real glass cups. Their heels clicked against the floorboards hastily laid to cover bare concrete. To the uninitiated, it might almost pass for legitimate nightlife. To Bruce, it was window dressing.

The smell gave it away: sweat, grease, cigarette ash ground into the floor.
Bruce followed Maroni and the other men toward a roped-off section near the cage.

The shipping magnate’s voice boomed, too loud for the room, already half-drunk.
“Now this, this is Gotham, Wayne. You want to know the city, you don’t look at your towers. You look here. Men in the dirt. Nothing faked. Nothing sterile.”

Bruce offered him a practiced smile and a nod, the kind that could pass for agreement without ever committing to one. He let himself be guided to a leather-upholstered chair, already worn and sticky with heat, and accepted a tumbler of scotch pressed into his hand by one of the girls. He lifted it, swirled the amber liquid once, and tasted. Decent, actually. They wanted this place to feel expensive, even if the walls told another story.

The cage at the center of the floor rattled as two men finished a brutal exchange. The crowd surged, bills fluttering in the air before changing hands. The referee raised the victor’s arm, and the loser stumbled out, his nose a ruin of blood.

Bruce leaned back, his eyes moving without much interest. He’d been to fight nights before. But this was theater. Violence wrapped in spectacle, dressed up enough for Gotham’s men of power to feel dangerous without leaving their comfort zone.

The house lights dimmed. A microphone screeched. The moderator slipped into the cage, a wiry man in a tuxedo shiny with sweat. His voice rose with a practiced rhythm, theatrical, selling drama as though the steel mesh were Madison Square Garden.

“Ladies and gentlemen! For your main event this evening—two fighters, one cage, one victor. Place your last bets, hold onto your glasses, and get ready for the fight you’ve been waiting for!”

The crowd roared. The floodlights buzzed brighter, cutting through smoke.

“First, entering the cage… standing at six foot even, weighing in at one-sixty-nine pounds, with a record of fourteen wins and five losses… Gotham’s own, the breaker of jaws, the king of the cage… Eddie ‘Jaw Breaker’ Gonzales!”

Music thundered through the speakers, heavy drums, bass deep enough to shake the scaffolding. A broad man strode out from behind the curtain, flanked by handlers in matching tracksuits. He grinned, soaking in the noise, slapping the steel mesh as he entered the cage. His body was thick with muscle, his movements casual, arrogant. The crowd shouted his name, bills changing hands already.

Bruce’s gaze was steady. Gonzales moved like a man who expected to win. He’d seen that walk before, in fighters and businessmen alike. Confidence that tipped toward complacency.

“And his opponent… fighting out of the East End… standing at five-nine, weighing in at one-fifty-six pounds, with a record of five wins and three losses… let’s hear it for Jason Todd!”

The music shifted. Lower, darker, something with a sharp edge of defiance in the riff. The crowd erupted, half cheers, half jeers.
Jason stepped out from behind the curtain, barefoot, his shoulders held taut like wire. Two men came with him, one barking in his ear, the other clapping his back too hard, rough encouragement that looked more like ownership than support. They pushed him forward, not gently.

Jason peeled his shirt off as they walked, tossing it aside without a glance, leaving only fight shorts that hung low on his hips. His body was lean but bruised, crisscrossed with old scars that caught the light. He didn’t raise his arms or play to the crowd. He looked straight ahead, his jaw locked.

Bruce felt the air change around him, though he couldn’t have said why.
No stance yet, no technique to study, just a young man climbing into a steel box against someone bigger, stronger, more experienced.

Bruce couldn’t place it, not yet. He only knew that for the first time that night, he wasn’t thinking about the dirt around him, the fake luxury displayed, the deals waiting in the morning, or the way Maroni was crowing beside him. He was watching Jason Todd.

The bell cracked and the cage door slammed shut behind them. Gonzales came out grinning, broad shoulders rolling as if the match were already his. Jason met him head-on, too straight, too raw, and the bigger man pounced.

The first punches were blunt instruments, crashing into Jason’s guard, forcing him back. A hook snuck through, snapping Jason’s head sideways; another slammed into his ribs with a dull thud. He grunted, teeth clenched, chin ducked, arms folding in tighter. The boy wasn’t countering yet. He was absorbing.

The crowd howled. Bruce watched the way Jason’s knees bent, not from panic but calculation. A pause, a measure of the rhythm. He’d seen it a lot before in sparring matches at the gym and in tournaments years ago: the difference between someone drowning and someone counting seconds underwater.

Beside him, Maroni laughed, full and guttural. “Kid’s a punching bag,” he said, slapping the armrest of his chair. He leaned toward Bruce, his cologne pungent, mixing badly with the stink of sweat and beer that hung over the warehouse. “Look at him. Takes a hit, doesn’t fold. That’s worth money in this town. Fellas like Gonzales, they burn out quick. Too much show. Todd? He’s got grit.”

Bruce swirled the amber in his glass, eyes never leaving the cage. “Grit only matters if you know when to stop bleeding and start thinking,“ he said evenly.

Maroni barked out a laugh, clapping his knee. “Spoken like a man who doesn’t know the odds. You’ll see. The kid’s tough, he’ll bleed for the crowd. That’s what they pay for.” He leaned closer, voice thick with liquor and triumph, and shouted across the noise, “Come on, Todd! I got good money on you! Don‘t make me look stupid!”

Jason seemed to have caught part of it. He flinched. Just a flick of his eyes toward the roped-off section, toward Maroni’s big meaty hand gesturing in the air. That heartbeat of distraction cost him. Gonzales drove a straight right into his jaw, snapping his head back. Jason staggered, almost fell. The crowd exploded with laughter and shouts, the sound like an ocean crashing all at once.

Maroni bared his teeth in a grin. “See? That’s what I mean. Gets knocked, but he ain’t glass. He’ll keep swinging ‘til you drag him out on a stretcher. Reliable.”

Bruce kept his gaze forward, jaw set. Reliable wasn’t the word he’d have chosen.
Jason recovered fast, too fast for someone his age and experience amd weight with that much force against him. He spat a ribbon of blood to the side and came in low, ducking Gonzales’ hook and throwing a short, mean punch into his ribs. Not elegant, not polished, but enough to make the bigger man grunt and stumble half a step.

The bell rang. Round over.

Jason walked back to his corner, shoulders rolling with the stiffness of impact. He lowered himself onto the stool, chest heaving. His handlers came at him in a rush, not with care but with impatience. One shoved a bottle at him; water spilled down his chin and chest, most of it wasted.

Another slapped him across the shoulder as if to jolt him awake, before barking orders at him, Bruce couldn‘t hear.

There was no ice pressed to his side, though the bruise already darkened the skin above his ribs. No clean towel, no soft word. Just cursory gestures, brusque orders. Efficient in the way one checks a horse’s hooves.

Bruce leaned forward slightly, studying. He’d seen tons of good corners: methodical, almost tender in their focus. This wasn’t that. The neglect wasn’t blatant enough to register to the crowd, but it stood out to him. The little things left undone. The absence of concern where concern should have been automatic.

The bell rang again, and Jason stood. Gonzales lumbered forward with the same easy arrogance he‘d started the first round with.

But this time Jason struck first. A jab, fast and sharp, splitting the air. Then another. Gonzales’ grin faltered as one caught his cheek, snapping his head back. Jason darted aside, footwork scrappy but alive, landing a kick low to the thigh that made a hollow, meaty sound. The crowd roared, some in surprise, others in delight at the sudden surge.

Bruce leaned in. There was intelligence in the shift. Jason had learned something from the first round: Gonzales was overcommitted. Too hungry for the big finish, he left spaces. Jason wasn’t polished, but he was trying to read those spaces now.

Still Gonzales barreled through another jab, caught Jason around the waist, and drove him into the mat. The cage rattled. Dust puffed up where sweat had darkened the canvas. The bigger man rained down blows, heavy and wild. Jason curled, legs thrashing, then managed to snake a heel under Gonzales’ hip and twist. For a moment, impossibly, he reversed, scrambling to his knees then and shoving free. The crowd bellowed.

Jason’s chest heaved, blood smeared across his mouth, sweat making his skin shine under the harsh lights. He kept moving, circling. Gonzales chased, annoyed now, throwing wild hooks. One landed.

Jason reeled, stumbled back into the fence, arms up. Gonzales pressed, forearm grinding into his face, fists digging into his ribs.

Bruce felt his own jaw tighten, an old phantom ache in his ribs answering each blow. He‘d bruised a rip, not only once, during a fight, but this was different. This was survival layered over pain, a boy using every ounce of cunning just to stay standing.

The bell cracked again.

Jason dragged himself back to the stool, every step marked by stiffness. His corner closed around him with a kind of restless impatience. Their words came hard and fast, swallowed by the roar of the crowd.

No towel to wipe the sweat that stung his eyes. No cool weight of ice for the bruise flowering dark across his ribs. One shoved a plastic bottle into his grip, more than half-empty now, condensation long gone, probably lukewarm.

Jason tugged out his mouthguard, the sound lost in the roar, and took a swallow. He swished, spat onto the floor. The liquid came up pink-red, pooling at his bare feet before soaking into the canvas.

Bruce watched the ritual with a tightening jaw. Corners were meant to be a sanctuary, a breath between storms, a place where strategy was rebuilt in fragments of sixty seconds. A proper corner protected a fighter, kept him functional, preserved what strength he had left.

This was no sanctuary. What he saw instead was neglect. They weren’t caring for him; they were pushing him back into the cage with the bare minimum. Enough to keep the show running, not enough to keep the boy whole.

Jason Todd was being driven, not protected. Treated like the outcome didn’t matter as long as he bled for it.

Jason hunched forward, forearms braced on his thighs, sweat dripping from his jaw. Blood slid from his split lip and fell in slow beads between his feet. He stared down at it for a breath, then lifted his eyes, not toward his corner, not for guidance, but outward. Toward the crowd. Toward Maroni.
The older man was laughing, drink in hand, cigar clamped between two thick fingers as he gestured, boasting to the men around him. Not watching the boy. Not seeing the bruise that spread dark beneath Jason’s ribs.

Jason eyes flicked again and this time, they caught Bruce. For a moment, the noise of the crowd seemed to fall away. Jason, bloodied and breathless, and Bruce, dry glass forgotten in his hand. The boy’s expression was not a plea, not even a challenge. Just a flash of awareness, like he had recognized something in Bruce’s face, a man watching, not wagering.

Then the bell rang again. Jason, bruised and stubborn, slipped the mouthpiece back between his teeth with a grim efficiency, jaw clenching around it. He stood on his own, legs steadying beneath him, and raised his fists. His stance wasn’t clean, but it was unbroken.

Bruce felt the shift in the air before the fight resumed. The boy was battered, yes, but not bowed. And that resilience, misused as it was, was the kind of thing that couldn’t be taught.

Across from him, Gonzales looked fresher, cocky, pacing with loose energy, smirking like he could already taste the win.

The crowd rose with the tempo of the music, a pounding bass that seemed to shake the cage itself. Sweat and smoke thickened the air. Bruce shifted forward on his chair, eyes locked on the younger fighter.

They met at the center. Gonzales struck first, heavy jab, right cross. Jason’s guard came up too late. The punch clipped his cheekbone, snapping his head sideways. He staggered, his knees buckling for a fraction of a second, but he didn’t fall.

The cage vibrated with the eruption of the crowd. Jason came back wild. He drove Gonzales against the mesh, reckless, with a flurry of punches, sloppy but fast, the kind that forced Gonzales to cover up. Fists thudded against arms, ribs, shoulders. Then Gonzales surged out, catching Jason around the waist.

They slammed to the mat. The breath rushed out of Jason’s lungs. Gonzales was heavier, stronger, pinning him with brute force. The crowd roared approval, chanting Gonzales’s name. Bruce’s jaw clenched.

Jason struggled under the weight.
“Stay down, kid!” Gonzales barked, teeth bared, sweat flying from his mouth.

Jason writhed beneath him, caught in the hold, and for a moment it looked like it was over. Gonzales rained short, punishing punches down at his head and shoulders. Each one landed with a sickening thud.

Jason absorbed another blow, body curling under the impact, but something inside him lit. Jason twisted, found leverage where none should have existed. He shoved upward with his hips, rolled hard, and suddenly they were reversed, Gonzales on his back, Jason straddling his torso, fists hammering. Blood - his own, Gonzales’s - it didn’t matter anymore, sprayed across the mat, metallic in the air.

“Finish him!” someone howled from the crowd. Jason’s right hand smashed into Gonzales’s jaw again and again, each strike weaker than the last, his own body failing him even as he tried to end it. Gonzales’s arms flailed, then stilled.

The ref dove in, pulling Jason back before he could throw another punch. The bell rang. The fight was done.

Jason staggered to his feet, chest heaving, sweat and blood streaming down his skin. there was no triumph in his face. Only exhaustion. His eyes swept the crowd once more, unfocused.

His corner stormed the cage, all grins and backslaps. One seized his wrist, yanking his arm into the air, parading him for the cameras as though Jason were a trophy, not the one who had earned the win. Another shoved a smile onto his own face, shouting over the crowd as though they had anything to do with it. Jason’s head lolled slightly as the announcement thundered overhead.

“Your winner - by technical knockout - Jason ‘Todd’!”

The crowd erupted again, a chaotic mixture of cheers and curses, money changing hands in fast, furtive exchanges. Maroni pounded his chair, laughing through a plume of cigar smoke.

Jason’s corner hauled him toward the gate, still shouting, still smiling. Jason moved under their pull, legs unsteady, mouthpiece jutting awkwardly from split lips.

The cage door slammed behind them.
Bruce remained in his chair, glass untouched on the table.
