## Titan's End: The Waybig Gambit
**Logline:** Reincarnated 15 years before Eren Yeager's birth with the power of Ultimate Waybig, a morally grey strategist sets out to permanently end the Titan threat by any means necessary, starting with the fall of Wall Maria and the brutal consumption of the Shifters he despises.
**Author's Note:** This story contains graphic violence, dark themes, and morally ambiguous choices. The MC operates on a brutal calculus for what he perceives as the ultimate good. Power scaling adheres strictly to Ultimate Waybig's planet-busting potential. No nerfs.

**Chapter 1: Dust and Destiny**
**(Third Person)**
The air in Shiganshina District tasted like dust and simmering tension. Fifteen years. Fifteen years spent waiting, observing, learning this harsh world's rhythms from the shadows. The man known locally as Kael, a quiet drifter with eyes too old for his apparent thirty years, leaned against a sun-baked stone wall. He watched children chase a makeshift ball, their laughter a fragile bubble against the looming immensity of Wall Maria. Inside, Kael seethed. He remembered the screams, the futility, the rivers of blood from a story etched into his soul – *Attack on Titan*. He remembered Bertholdt Hoover's colossal foot smashing this very gate.
**(First Person)**
Fifteen years of simmering hatred. Fifteen years planning the extinction of a curse. The Eldians, Marley, the King in the Walls... they were all players in a game rigged for endless suffering, fueled by the power of the Titans. My power – Ultimate Waybig – wasn't from this world. No Omnitrix, just the terrifying certainty of the transformation. I was the asteroid meant to shatter their cycle. Morality? A luxury for those who haven't seen the future. I aimed for the *least* bloodshed overall. If that meant sterilizing an entire people to erase the Titan gene... so be it. Better than millennia of devouring. Today, the script began. Today, Bertholdt dies.
**(Third Person)**
A sudden hush fell over the district. The air pressure dropped, ears popped. Then, an impossible heat bloomed beyond the wall. A colossal, skeletal head, wreathed in steam, rose like a blasphemous sunrise over the top of Wall Maria. Gasps turned to shrieks. The Colossal Titan. Right on time. Kael didn't flinch. He saw the sheer, dumb terror on faces that mirrored millions he'd witnessed only in memory. This was the catalyst. This was his cue.
**(First Person)**
There he was. Bertholdt Hoover. The boy who would kickstart hell. My hatred for him, for all the Shifters, was a cold, hard thing. They wielded power that caused nothing but pain. Today, they learned true powerlessness. No grand speeches. No warnings. Just annihilation. Time to introduce them to cosmic justice.
**(Third Person)**
As the Colossal Titan's foot drew back, poised to obliterate the Shiganshina gate, Kael moved. Not towards shelter, but towards an open square directly facing the impending destruction. People screamed, scrambling past him. He ignored them. His focus was absolute. A low hum, inaudible to human ears, began to emanate from him. The air crackled with static.
Then, light. Blinding, searing white light erupted from Kael's form, expanding outwards with terrifying speed. It wasn't fire; it was pure, concentrated energy, warping the very air. Where Kael stood, space itself seemed to distort. The light coalesced, shaping itself into impossible dimensions. Stone buildings near the epicenter didn't just crumble; they *sublimated*, turning instantly to dust and vapor.
When the light faded, Shigansha District held its breath, momentarily forgetting the Colossal Titan.
Standing where Kael had been was a being of impossible scale. Over 300 feet tall, dwarfing even the Colossal Titan. Its body was sleek, alien armor the color of deep space and starlight, segmented with glowing green energy lines that pulsed like a heartbeat. Massive, fin-like protrusions swept back from its head, framing eyes that burned with cold, emerald fire. Its hands ended in claws capable of rending continents. This was Ultimate Waybig – a cosmic engine of destruction incarnate.
The Colossal Titan froze mid-kick, its single glowing eye fixed on the entity that had appeared before it. Steam billowed around it in frantic, confused clouds.
**(First Person)**
The shift was instantaneous. No strain. Just... becoming. The world shrank beneath me. The Wall Maria was a toy fort. The Colossal Titan? A startled, steaming mannequin. Bertholdt's confusion radiated off him. Good. Let him feel the fear his victims felt. This wasn't about saving Shiganshina yet. This was about sending a message. To *him*. To *them all*.
**(Third Person)**
Ultimate Waybig moved. It wasn't a step; it was a spatial translation. One moment it was in the square, the next, it stood directly before the Colossal Titan, outside Wall Maria. The ground didn't just shake; it fractured for miles, deep crevasses opening like wounds in the earth. Waybig's sheer mass displaced the air with a thunderclap that shattered every remaining window in the district and knocked people off their feet miles away.
The Colossal Titan stumbled back, steam erupting violently as its instincts screamed *danger*. It swung a massive fist, a blow that could level a town.
Waybig didn't dodge. It raised one clawed hand, palm open. The colossal fist impacted the palm with a sound like mountains colliding. Dust and superheated steam exploded outwards. Waybig's arm didn't budge an inch. The force wave flattened trees for kilometers. Inside the palm, the Colossal Titan's fist bones visibly cracked and crumpled like dry twigs against the alien armor.
**(First Person)**
Pathetic. His strength was nothing. Like a child hitting steel. I felt the crunch of bone through my cosmic senses. Bertholdt's shock was a tangible thing. He thought *he* was a monster? He had no idea. Time to end the prologue.
**(Third Person)**
Before the Colossal Titan could react, Waybig's other hand shot forward. Not to punch. To *grab*. Enormous claws, glowing with restrained power, closed around the Colossal Titan's torso with terrifying speed. They punched through the steaming muscle and hardened flesh like it was wet paper, finding purchase on the rib cage beneath. Bertholdt, trapped within the Titan's nape, felt a surge of primal terror as the world outside his Titan suddenly became an unbreakable cage of cosmic metal and searing energy.
Waybig lifted. Effortlessly. The Colossal Titan, a being of legend and terror, was hoisted into the air like a struggling doll. Its legs kicked futilely, steam pouring from every pore in a desperate, useless defense. Waybig brought the steaming giant close to its own emerald-eyed face.
**(First Person)**
I saw it. The tiny human form embedded in the neck. Bertholdt Hoover. The fear in his eyes was... satisfying. This was the powerlessness. The helplessness. Just like Marco. Just like Hannes. Just like everyone they ever trampled. No grand speeches. Just consumption. I opened Waybig's maw. Energy gathered, a vortex of green light swirling between crystalline teeth capable of biting through planets.
**(Third Person)**
Waybig bit down. Not on the Titan's head, but directly on the upper torso, encompassing the nape. There was a sound unlike anything heard on that world before – a horrific tearing, crunching, *vaporizing* noise as cosmic energy met Titan flesh. The Colossal Titan's upper body simply *disintegrated* in a flash of green light and superheated plasma. Steam exploded outwards, a final, violent burst, before dissipating rapidly.
The massive lower legs and hips, now headless and nape-less, collapsed like felled trees, shaking the earth again before rapidly decomposing into nothingness, leaving only a faint, greasy residue on the broken ground.
Held within Waybig's claw, amidst fading wisps of steam and glowing embers of annihilated matter, was a small, scorched human figure: Bertholdt Hoover, unconscious and broken, but alive. The power of the Colossal Titan, severed from its host, thrummed like a dying star within Waybig's cosmic grasp. With a thought, Kael *pulled*. The Titan power, a fundamental force of Paths, was ripped from Bertholdt's fading soul and absorbed into the infinite well of Waybig's own energy matrix. The Curse of Ymir meant nothing to a being forged in the void between galaxies. Bertholdt's body went utterly limp, a hollow shell.
**(First Person)**
One down. The power settled inside Waybig like a captured ember. Useful. Necessary fuel for the final act. Bertholdt was just meat now. Expendable. I dropped the broken body. It fell like a stone, impacting the ravaged earth far below with a sickening thud. Irrelevant. The message was sent. The Attack Titan, the War Hammer, the Beast... they would have felt that. Let them tremble.
**(Third Person)**
Ultimate Waybig turned its burning gaze towards the gaping hole in Wall Maria, where the terrified faces of Shiganshina survivors peered out, frozen in awe and abject terror. The Armored Titan, Reiner Braun, hidden nearby and paralyzed by shock, watched the cosmic entity that had just devoured his comrade and god-like power in seconds. Deep within Wall Sina, a sleeping Founding Titan stirred uneasily. Across the sea, in Marley, Zeke Yeager felt a sudden, icy dread grip his spine.
Waybig raised a clawed hand towards the hole in the wall. From its palm, a controlled beam of green energy lanced out. It wasn't destructive; it was cohesive, binding. Stone, metal, and vaporized debris surged upwards as if time reversed, knitting together with impossible speed. Within moments, Wall Maria stood whole again, seamless, as if the Colossal Titan's attack had never happened. Only the devastated landscape outside, and the broken body near the wall's base, bore witness.
The cosmic titan looked down at the insignificant humans cowering within the walls. Its voice, when it spoke, wasn't sound; it was a psychic projection that vibrated in the skull of every living being within a hundred miles, cold, emotionless, and final:
**"THE TITAN LINE ENDS HERE. THE SHIFTERS ARE MINE."**
Then, in another flash of blinding light that forced everyone to shield their eyes, Ultimate Waybig was gone. Only Kael remained, standing alone amidst the settling dust on the reclaimed ground outside the pristine wall, the stolen power of the Colossal Titan a new, dark star burning within him. The path to sterilization had begun. The hunt for the remaining eight was on.
