The First Runeterran Titan

Summary:

Jinx fires the last rocket. But not to end Piltover. To end the lie that the walls between the cities were ever just stone.
The blast clips something older than hextech, buried since the Rune Wars: a containment seal that never kept Zaun out or topside in. It kept monsters in.
The sky tears open. Green lightning. Roars that taste like pine and blood. Titans fall through the shimmer fog, Eren Jaeger mid-Rumbling rage, Mikasa mid-swing, Levi mid-slice, Armin mid-despair, the last broken Scouts crashing into a war they already lost once.
Eren’s eyes open in the shimmer lake and meet Jinx’s across the steam. No words. Just recognition. Two kids who’ve already ended worlds for the taste of being free.
Vi screams “POWDER!” like the word can still pull her sister back from the edge.
Caitlyn lowers her rifle and makes the only promise that still matters: she will choose Vi even if both skies fall.
Mikasa finds something soft in Ekko’s stubborn hope.
Levi finds something almost human in Jayce’s golden-boy guilt.
Armin and Viktor stare at the Hexcore and realize: history isn’t a cycle. It’s a choice.

The walls were never to keep anyone out.
They were to keep the monsters in.

Notes:

hii hii HIII !! 😚😚💗 this fic features multiple canon-divergent ships. vi/caitlyn is the main one; the others develop slowly and organically. if you're here only for one ship, that's fine, just know the others are present and get real development~

Chapter 1: The Dirt Under Your Nails

Chapter Text

The Hexgate was eating itself alive, and the dirt under everyone’s nails was finally showing.

Golden hextech veins crawled up the metal like rot in a corpse, Viktor’s Glorious Evolution pulsing in sick rhythm while the Entresol—the literal middle wall between Piltover and Zaun—groaned and split under Noxian war machines and Firelight hoverboards carving purple contrails through chem-fog. Marble bridges that once gleamed white were now slick with shimmer runoff the color of piss and blood. The air smelled of ozone, gunpowder, burning dreams, and the faint iron of old lullabies no one had sung in years.

Every layer of dirt, every scar, every secret the cities had buried for centuries was finally clawing its way to the surface.

The Hexgate tower loomed exactly as it had in the final broadcast—half-devoured by Viktor’s golden runes crawling like living veins up blackened steel. Below, the same Entresol layers that had always pretended to separate Piltover from Zaun now cracked like cheap porcelain under the weight of everything the powerful had tried to keep down.

 

Ekko’s voice cracked over the wind exactly like it had in the show. “Jinx, we can still—”

She cut him off with a wild laugh that tasted like battery acid and birthday candles. “Still what, Bomb-boy? Fix the unfixable? Cute. Stupid. Mine.” She ruffled his hair with the hand not holding Fishbones, the same rough affection she used to give him when they were kids painting murals on sump walls. Sevika grunted from the controls, chem-arm whirring, the only person left who still looked at Jinx like she was a loaded gun worth aiming.

Far below, Viktor’s voice rolled calm and terrible across the battlefield, the exact words from every nightmare since the Hexcore first sang: “It is the answer you and I pursued all our lives. An end to cruelty. Injustice. All of us our own authors to an unbroken saga…”

Jinx’s laugh cracked jagged and too loud, braids whipping like live wires. “Yeah, well, perfect’s boring, tin-man. Some of us like our imperfections with a little boom.” She spun Fishbones once, the rocket launcher heavy and familiar, and fired a single warning shot into the chem-fog just to watch the purple bloom. “Boom for the people! Boom for the dirt!”

Ekko’s eyes went wide. “Jinx, that’s not—” “Relax, Bomb-boy,” she cut in, grinning wider. “I’ve got a plan. It’s called ‘biggest explosion ever’ and it’s gonna be art.” Sevika’s chem-arm whirred in approval.

 

She spotted Vi—gauntlets blazing blue, muscles straining exactly like they had every time Vi tried to save something that couldn’t be saved. Caitlyn was a blue-white flash on a distant rooftop, rifle barking with that perfect topside precision. Ambessa moved like a war goddess who’d decided armor was for weaklings. Mel’s golden barriers flared against Black Rose shadows. And somewhere in the mess, Vander’s ghost was still trying to eat them all.

And then there was the beast.

Warwick—Vander—thundered up from the docks, claws and rage and the ghost of lullabies in the Lanes. He smashed through a Noxian phalanx like it was paper, eyes glowing that awful chem-green, howling for blood, for family, for everything they’d lost twice over. Jinx’s fingers tightened on Fishbones until the metal bit. Time to go home, sis.

She leapt. Wind screamed past her braids. Ekko’s shout—“Jinx, wait!”—got shredded behind her. She hit shimmer-hard, veins burning pink, and tackled Warwick mid-air like the crazy bitch she was. Claws and gauntlets and three broken hearts slammed onto the narrow ledge.

Vi’s voice cracked raw exactly as it had in every nightmare Jinx still had: “Powder—get back!”

Jinx grinned wider, manic and bright, but her chest was already cracking open. “Can’t. Family reunion, remember?”

Vi’s gauntlet was iron around her arm, pain flaring honest and bright. Warwick’s claws sank into her coat, dragging, and the entire walkway groaned like it was sick of all of them. Three bodies, one gauntlet, two dead fathers, and the weight of every promise they’d ever broken pulling them toward the abyss.

Inside Vi’s head the same loop played that had played since the tea party: I failed her once. I won’t again. I can’t. Her muscles ached, the gauntlets flashing dangerously, trying to hold both her sister and the monster that used to read her bedtime stories. Every scar on her knuckles, every bruise from every fight she’d ever lost for Powder, screamed in protest. The shimmer-pink glow under Jinx’s skin was the only thing still keeping her sister breathing—and it was killing her at the same time.

Not again. Not Powder. Not Vander. Not like this. Vi’s vision tunneled to her sister’s manic grin, to the beast that used to sing them both to sleep now trying to tear them apart, to the memory of Powder’s tiny hand in hers the night everything first broke.

Jinx looked up into Vi’s face—streaked with tears and blood and that same stubborn love that had ruined them both since they were kids. The kind of love that never learned how to let go.

Always with you, Vi. Her free hand moved fast, precise—and punched the weak seam. The hexgem popped free with a crystalline ping that sounded like every cage she’d ever blown open.

Vi’s eyes went wide with horror. “Powder—no—”

 

Gravity took them. Jinx and Warwick fell. Wind howled. The city spun above them—bridges, lights, Piltover’s arrogance and Zaun’s rage all blurring into one long scream.

Jinx wrapped her arms around the beast’s neck the way she used to hug Vander after nightmares. His claws dug into her back but she didn’t flinch. Shimmer surged hot in her veins—pink glow flaring under her skin exactly like the show left us—keeping her alive, keeping her laughing. She pulled the pin on the grenade tucked against her chest—the same one she’d almost used on herself back in the hideout, hexgem-charged, the kind that painted the sky blue and made the monsters go quiet.

“See you on the other side, old man,” she breathed against matted fur, voice cracking for the first time in years. “Tell Silco I said hi. And… tell Powder I tried.”

She laughed once—sharp and wild, the sound of a girl who’d finally decided the joke was on the universe. “Family reunion’s a real blast, huh? Get it? Blast?”

Jinx twisted mid-fall, still grinning like the crazy bitch she was, and flicked a tiny shimmer pellet at Warwick’s nose just to watch it spark. “C’mon, old man—one last dance before we all go boom? Don’t say I never gave you anything!”

She grinned up at her sister one last time, manic and bright and already halfway to gone. “Always with you, sis.”

For a single heartbeat the world narrowed to Vi’s face—streaked with tears and blood and that same stubborn love that had ruined them both since they were kids. The kind of love that never learned how to let go.

 

The grenade detonated. Light. Heat. Blue-white fire that tasted like every scream she’d ever swallowed and the dirt under Vander’s nails when he used to tuck them in at night. Vi’s scream ripped through everything—“POWDER!”—raw and broken and eternal.

Deep beneath centuries of progress and rot, something older than hextech woke up. The blast clipped it dead-center—ancient glowing runes that looked eerily like hextech but crueler, hungrier, carved with symbols that predated Piltover by a thousand years. The containment field that had held since the Rune Wars tore like wet paper.

For one impossible second Jinx saw it in her mind’s eye—not just runes, but walls. Giant. Living. Breathing. Walls that had never been meant to keep Zaun out or Piltover in. Walls built to keep something far worse inside. Green lightning—the color of forests that had never existed in Runeterra—cracked through purple chem-clouds. The air screamed with voices that weren’t from this world: roars that sounded like the end of everything and the beginning of something worse. And for the briefest flash, in the heart of the tear, Jinx swore she smelled pine forests and blood and freedom so sharp it cut the roof of her mouth, and she saw a boy’s eyes—green, endless, carrying the exact same fire she carried in her chest. The kind of fire that had already ended one world and was ready to end another just to feel free.

 

The sky above the Hexgate ripped open with a sound like the universe clearing its throat and deciding it was done with walls.

Jinx hit the broken girder first. Shimmer and whatever the grenade had done kept her breathing. She rolled, coughed smoke, laughed because it was that or scream forever. Coat shredded. Fishbones still in her grip. Singed braids stuck to her face. She tasted copper and ozone and something new: pine forests and blood and freedom so sharp it cut the roof of her mouth.

She looked down.

Fifteen meters of rage and steam and green eyes that had already watched the world end once lay half-submerged in the shimmer lake. It was shrinking, human form bleeding through the vapor. A boy—naked, scarred, breathing hard. When his eyes opened they held the exact same fire she carried in her chest: the kind that said I will burn every cage that ever tried to hold me, even if I burn with it.

Jinx tilted her head. Grinned that blue-chaos grin the undercity both feared and loved. She hopped down lightly, boots splashing in shallow chem-water. Leaned over him. Poked his steaming cheek with the barrel of Fishbones, gentle as a lover who’d already decided to blow up the world together.

“New blue friend?” she asked, voice soft and unhinged and delighted. “Or… green? Eh, close enough. Welcome to the family, bomb-boy 2.0. You look like you’ve already killed a couple continents. Cute.”

The boy’s eyes snapped fully open. Post-Rumbling exhaustion. Fresh, endless fury. Recognition—like staring into a mirror that had already seen every wall fall and still wasn’t satisfied.

He didn’t speak. Not yet.

But Jinx felt it in her bones like a second heartbeat. He got it.

 

Somewhere far above, Vi’s scream still echoed off the cracking walls. “POWDER—!”

Far above the chaos, Caitlyn lowered her rifle, one eye still patched, heart shattering at the sound of Vi’s scream. She didn’t know the sky had just torn open. She only knew her partner was breaking again. And somewhere deep in her chest, the unbreakable older-sister promise burned like a vow: I will choose you even if the world ends twice.

The walls—both cities’ walls, all the walls—had never been there to keep anyone out.

They had been there to keep the monsters in.

And now the monsters were free.

And the dirt under their nails was going to stain everything.
