THE LAST
OMEGA
An Original Ultimate Alien Story
When every alien fails, one Ultimate transformation decides the fate of the universe.
▼ BEGIN STORY ▼
⚡ Opening Hook — 0:00–0:12
The Omnitrix explodes with green light — and shatters.
Ben Tennyson stands alone in a crater the size of a city, surrounded by thirty thousand Highbreed soldiers, and one weapon that has never been used before…
a transformation the Omnitrix was never meant to unlock.
⬡ ACT I ⬡
Scene 01 — Earth Orbit / Bellwood
THE SIGNAL FROM NOTHING
It starts with silence. The kind that shouldn't exist in space.
PLUMBER sensors across the galaxy go dark — not jammed, not destroyed. Just... gone. Like something deleted the signal from history. Kevin Levin slams every console on the ship. Gwen's mana threads feel it too — a cold tear in the fabric of something ancient.
"Ben — the Omnitrix just registered a species that's been extinct for six million years." — Gwen
Ben stares at the glowing dial. It's cycling on its own. Alien after alien flashing — faster than he can read — until it locks. A silhouette he's never seen.
"Who are you?" — Ben (to his own wrist)
The Omnitrix doesn't answer. But the sky does.
A beam of violet light punches through the clouds above Bellwood. And from it descends NULLIVORE — a being made entirely of erased matter.
NULLIVORE
The Eraser / Prime Antagonist
An ancient sentient void-entity that predates the Milky Way. Nullivore does not destroy things — it erases them from having ever existed. Heroes hit by its Omega Erasure don't die; their entire existence — memories, impact, legacy — is deleted from the timeline retroactively. It arrived because it detected the Omnitrix containing DNA of Celestialsapiens — the only species that can permanently un-erase what it has taken. If it destroys the Omnitrix, nothing can restore what it steals.
⬡ ACT II ⬡
Scene 02 — Bellwood Downtown
FIRST WAVE — BEN TRANSFORMS
Nullivore's vanguard — a thousand Erase-Drones — descend on Bellwood. Ben wastes no time.
🟢 OMNITRIX ACTIVATED
HUMUNGOUSAUR
Vaxasaurian — Strength / Size Manipulation
Ben slams the dial. Green light rips upward — 60 feet of armored dinosaur crashes onto Main Street. Humungousaur's roar shakes glass from buildings three blocks away. He tears through the first wave of Erase-Drones like cardboard, each swing sending arcs of their grey matter scattering. But the drones adapt — they phase partially out of existence, and Humungousaur's fists pass straight through them.
🟢 OMNITRIX — SWITCH
FASTTRACK
Citrakayah — Velocity / Agility
Ben cycles to Fasttrack — lean, feline, built for pure speed. He blurs at Mach 8 through drone formations, the shockwave alone detonating clusters of them. He uses his speed to stay ahead of the erasure field that follows Nullivore — but as he moves, he notices something horrifying: buildings behind him are beginning to flicker. Not destroyed — flickering out of existence entirely, like someone is deleting them frame by frame.
🟢 OMNITRIX — SWITCH
LODESTAR
Biosovortian — Magnetic Mastery
Ben becomes Lodestar — floating magnetic core, metal spiked shell, electromagnetic control. He weaponizes the city's own infrastructure — ripping iron girders, manhole covers, cars, satellite dishes into a vortex of shrapnel and hurling it at the drone swarm. It works. For thirty seconds. Then Nullivore itself descends, and the magnetic field bends around it — absorbed, erased, gone.
"Every power you use, I catalog. Every transformation you make, I record. And then… I erase the version of you that learned it." — Nullivore
Kevin and Gwen arrive, but even Gwen's mana shields dissolve on contact with Nullivore's aura. Kevin absorbs concrete — it crumbles to powder. They are completely useless against it.
🟢 OMNITRIX — SWITCH
TERRASPIN
Geochelone Aerio — Wind / Vacuum Generation
Ben switches to Terraspin — turtle-like, propeller-limbed, immune to mana and energy attacks. He spins his hollow body to generate a hurricane-force vacuum, trying to physically push Nullivore back into the sky. It almost works — Nullivore rises 200 feet. Then it erases the air itself in a 30-foot bubble. Terraspin can't generate wind from nothing. Ben reverts, gasping.
🟢 OMNITRIX — SWITCH
AMPFIBIAN
Amperi — Electricity / Intangibility / Telepathy
Desperate, Ben goes intangible — glowing jellyfish form, crackling with blue-white lightning. He phases directly INTO Nullivore's body, firing terawatts of electricity from inside. For the first time, Nullivore flinches. Electricity is the one thing it can't erase — energy disperses too fast to catalog. But it adapts in ten seconds and begins erasing AmpFibian's neural patterns mid-transformation. Ben is forced out, barely coherent.
As Ben reverts, the Omnitrix scans Nullivore involuntarily — and something ancient deep inside the device activates. A black hourglass core beneath the dial begins glowing violet. Azmuth's voice crackles through an emergency channel: "Benjamin. Do NOT press that transformation. The Omnitrix was never certified for what you just unlocked." Ben looks down. The dial shows a silhouette he has never seen — a species marked in the Omnitrix database as CLASSIFIED: OMEGA PROTOCOL.
⬡ ACT III ⬡
Scene 03 — Ground Zero / Bellwood
THE EVOLUTION PROTOCOL
Nullivore begins erasing Bellwood block by block. Gwen watches her childhood home flicker and vanish — not destroyed, simply never there. She screams. Kevin drives a truck into Nullivore. The truck evaporates mid-flight.
"This world has 4 minutes of existence remaining. The boy's device will be the last thing I erase. I want him to watch everything go first." — Nullivore
Ben looks at the Omnitrix. Four minutes. He has one shot.
He doesn't press the Omega Protocol dial yet. Instead — he knows Nullivore adapts to any alien it's seen. He needs something it has NEVER encountered.
🟢 OMNITRIX — CALCULATED SWITCH
JURY RIGG
Planchaküle — Mechanical Deconstruction / Reconstruction
Ben becomes Jury Rigg — tiny, devilish, obsessed with breaking and rebuilding machines. This is the plan: Jury Rigg tears apart Kevin's ship in 40 seconds flat and rebuilds it into a Null Void Projector aimed directly at Nullivore — not to trap it, but to open a temporary rift that momentarily anchors Nullivore to physical existence. If it's anchored, it CAN be hit. Gwen holds the rift open with every last gram of mana she has. Kevin uses his own life force to power it.
The rift tears open. Nullivore screams for the first time — a sound like a universe being unmade. It's anchored. For maybe sixty seconds.
"NOW, BEN!" — Gwen
Ben looks at the Omnitrix. The Omega Protocol dial pulses violet and green simultaneously. He thinks of everyone Nullivore erased — everyone who never got to know they were gone. He slams the dial down.
⚡ ULTIMATE SEQUENCE INITIATED ⚡
ULTIMATE
SWAMPFIRE
🔶 ULTIMATRIX ENGAGED — EVOLUTION PROTOCOL
ULTIMATE SWAMPFIRE
Evolved Methanosian — Omegafire / Biological Reality Anchor
The transformation is unlike anything Ben has ever felt. Ultimate Swampfire doesn't just evolve — he becomes the biological counterforce to erasure.
His body ignites — not orange flames, but white-gold fire that radiates at the molecular frequency of existence itself. Where Nullivore erases matter from reality, Ultimate Swampfire's fire re-writes it back. His vines are crystalline, unbreakable — grown from a species that survived six extinction events by bio-adapting at the genetic level in real-time.
His fire is not heat. It is memory. Every burst of flame carries encoded existence data — it re-manifests erased matter on contact. The buildings Nullivore deleted begin to flicker back. Gwen's home reappears. People who were erased mid-step stumble back into being, confused and unharmed.
Ultimate Swampfire stands 18 feet tall, every vine humming with white fire, eyes burning like two suns. He is the first being in 6 million years that Nullivore cannot catalog — because his power doesn't fight erasure. It makes erasure irrelevant.
"You erase things because you're afraid of what they become. I'm what they become." — Ultimate Swampfire / Ben
Ultimate Swampfire launches a nova of white-gold fire directly into Nullivore's core. Every beam of his flame rewrites the erased zone — faster than Nullivore can delete it.
Nullivore unleashes its most powerful attack — the Total Omega Erasure, a pulse that would delete the entire solar system from ever having existed. Ultimate Swampfire raises both arms and unleashes every vine, every flame simultaneously — not as a weapon, but as a reality broadcast, flooding the pulse with existence data at lightspeed.
The two forces collide. For three seconds, the entire galaxy holds its breath.
"HERO — GOING — ULTIMATE!" — Ben Tennyson
The white-gold fire wins. Nullivore dissolves — not erased, but restored against its will back to the original matter it was made of: stardust from the first second of the universe. It drifts harmlessly into space, finally existing again after six million years of being nothing.
Ben reverts. Collapses to one knee. The Omnitrix goes dark for five seconds — then pulses green. Gwen and Kevin run to him. Bellwood is whole. The universe still exists.
"You used a transformation Azmuth said not to." — Gwen
"Azmuth also said the Omnitrix was for protecting all life. I think that includes making sure life… still happened." — Ben
Epilogue — 48 hours later. Azmuth arrives on Earth. He stares at Ben for a long time. Then he opens a panel on the Omnitrix and installs a new core — deep violet, marked with a species glyph no one has ever translated.
"The Omega Protocol unlocked something else when you used it, Benjamin. There are now seventeen new transformations in your device. None of them are from this universe."
He leaves without another word. Ben looks at the dial. Seventeen new silhouettes glow. The last one is shaped exactly like Nullivore.
