Asgard. Bifrost Bridge Hub.
Loki watched the thumbs-down through the Observatory's viewing lens, and something inside him snapped.
The veins on his hand bulged around Gungnir's shaft. His face — usually arranged in an expression of charming menace, the kind of smile that made you check your pockets — had twisted into something raw and ugly.
"A mortal... dares to defile a god's weapon."
The humiliation was total. He hadn't just failed to kill Thor. He'd gifted the Allfather's ultimate weapon to the enemy. Handed it over like a birthday present. If word reached the other realms — if the dwarves heard, if Vanaheim heard, if anyone heard — his authority as king would be a joke told at feasting tables for the next thousand years.
"If I can't have it—" Loki's eyes went flat and manic in the same instant. "—then none of you will live."
He drove Gungnir into the Bifrost control console with both hands, channeling divine power at a rate that made the golden machinery scream. Deep inside the Destroyer's Uru shell, buried in enchantments older than most civilizations, a sequence activated that only the weapon's creator had ever known about.
The self-destruct protocol.
"For the glory of the king... be destroyed."
Earth. New Mexico.
Jake felt it before the warnings came.
The Destroyer's metal shell — which had been responding to his control with smooth, almost eager compliance — suddenly went hot. Not warm. Not heated. The kind of hot that said something fundamental had changed at the molecular level, and whatever was happening inside this shell was no longer interested in being controlled.
[WARNING: Exponential surge detected in magical core energy!]
[WARNING: Irreversible self-destruct sequence activated!]
[Countdown: 5 seconds!]
The green hourglass on the Destroyer's faceplate flashed red. Inside the Uru shell, divine power — raw, uncontrolled, and building toward critical mass — rampaged through every rune and every joint, trying to convert the entire structure into the universe's most expensive fragmentation grenade.
Self-destruct? Are you KIDDING me?
Jake ran the numbers in a fraction of a second. A divine artifact made of Uru metal going critical. The blast radius would be five kilometers minimum. Everything within that sphere — the base, the agents, Thor, Tony, the town of Puente Antiguo in the distance — would cease to exist.
Upgrade could control hardware. Upgrade could not wrestle a runaway magical chain reaction into submission. If he stayed merged, he'd be vaporized along with the shell.
"Eject! NOW!"
The black liquid metal ripped away from the Destroyer in a violent separation, peeling off like a second skin being torn free. Jake tumbled through the air, the Mechamorph form dissolving mid-flight, and hit the ground as a human teenager — skidding, rolling, tasting dirt and blood.
Behind him, the Destroyer had become a star.
The Uru shell was melting, collapsing inward, the contained energy warping the air around it into visible distortion waves. It wasn't an explosion yet — but it was about to be, and when it went, it would go with the force of a tactical nuclear weapon.
"RUN!" Tony's voice cracked through the chaos, his damaged Mark V scanners throwing readings that were climbing toward infinity. "The yield is equivalent to a tac-nuke! At this range, we cannot outrun this!"
"Then we don't run!"
Jake was on his feet. Bruised, bleeding from a cut on his forehead, breathing hard — but his eyes were the sharpest they'd ever been. The eyes of a man doing very fast math with very high stakes.
Four Arms. Enough raw strength to contain the blast physically — but no protection against the radiation and thermal output. He'd melt.
Diamondhead. Enough defensive hardness to tank the heat — but not enough structural mass to suppress a shockwave this size. The crystals would shatter.
Neither one alone can do this.
But together—
"System!" Jake's finger was already moving across the dial, swiping two icons on top of each other with the desperate precision of a man playing his last card. "Activate Genetic Fusion!"
This was it. The single-use trial he'd earned from the Iron Monger battle. One fusion. Five minutes. His only trump card for a situation exactly this catastrophic.
[Command confirmed.]
[Fusing: Tetramand (Strength Paradigm) + Petrosapien (Defense Paradigm).]
[Fusion initialization: Complete.]
Jake slammed the dial.
The light that erupted wasn't green. Wasn't red. Wasn't crystal-clear.
It was both — a swirling fusion of deep crimson and translucent gemstone green that spiraled into the sky like a double helix made of light, bright enough to cast shadows across the entire desert.
When it faded, something new stood on the battlefield.
Something that had never existed before in any universe.
Nearly thirteen feet tall — bigger than standard Four Arms, broader, denser. The base form was Tetramand: four arms, four eyes, the fundamental architecture of a species bred for combat. But every inch of that massive red frame was encased in a layer of thick, translucent crimson diamond armor — Petrosapien crystal, fused into the musculature at a cellular level. Massive crystal spikes erupted from his back like a crown of blades. And those four arms — each one thicker than a man's torso — glowed with a deep, pulsing red light, as if the diamond itself was alive and angry.
Diamond Arms.
"ROOOAAAR!!"
The roar that came out was unlike anything the Omnitrix had ever produced — not fire, not thunder, not the chime of crystal. It was the sound of stone and metal colliding at geological scale, a tectonic groan given voice and fury.
Diamond Arms didn't hesitate. Didn't calculate. Didn't wait.
He charged.
Thirteen feet of crystal-armored muscle moving at a dead sprint toward a divine weapon that was three seconds from going nuclear, each footfall cracking the desert floor like an earthquake in miniature.
"GET — BACK — INSIDE!"
Four crystalline arms spread wide — massive, diamond-hard, glowing red — and clamped around the Destroyer's superheated shell like a hydraulic press closing on a bomb.
SSSSSSSZZZZZZ—!!
The heat was beyond measurement. The Destroyer's surface had exceeded the temperature of a star's corona, and the moment Diamond Arms made contact, the air between them simply stopped existing — flash-vaporized into plasma. Any other form in Jake's arsenal would have melted on contact.
But the crimson diamond armor held.
It didn't just hold — it grew. The Petrosapien genes kicked into overdrive, and massive formations of red crystal erupted from Jake's arms, from his shoulders, from his back, spreading across the Destroyer's body in a racing wave of diamond growth. Layer after layer after layer — building, thickening, hardening — constructing a crystal coffin several meters thick around the divine weapon in the span of a single heartbeat.
"CONTAINMENT!"
Jake roared the word like a command to the universe itself, and the red crystal sealed shut.
BOOOOM—!!!
The Destroyer detonated inside its prison.
The shockwave was beyond anything that had happened on this battlefield — a concentrated blast of Odin's divine power, trapped in a confined space, hammering against the walls of its cage with the force of a god's dying scream. Cracks raced across the coffin's surface. Blinding white light shot through the fissures like searchlights in a cathedral.
CRACK... CRACK... CRACK...
Jake gritted his teeth — all four jaws clenched, every crystal fiber straining. His four arms locked around the coffin in a death grip, pouring every ounce of Tetramand strength into keeping it together. The ground beneath him didn't just crack — it collapsed, his legs sinking two meters into the earth as the shockwave tried to push him through the planet.
"It's... a little... hard to hold!"
Diamond Arms' defense was monstrous. Tetramand strength was legendary. But this was the self-destruct of a weapon forged by the Allfather of Asgard, and the crystal coffin was failing. Fractures widened. Light poured through. Another second — maybe two — and the containment would shatter, and all that divine force would release in every direction.
In the ruins, twenty meters away, Thor watched.
A creature he'd never seen before — crystal and muscle, red and diamond, four arms locked around a bomb that could level a city — was holding the line. Alone. Bleeding light through a hundred cracks. Sinking into the earth under the strain.
Fighting his brother's weapon. Containing his family's power. Protecting people who weren't even his people.
Something cracked inside Thor that had nothing to do with bones.
"No..." His voice was hoarse. Raw. "This isn't his fight."
He clenched his fists. And in that moment, standing in the mud and the rain and the ruins of everything he'd lost, he heard his father's voice — not as a memory, but as something deeper. Something carved into the bedrock of who he was.
Whosoever holds this hammer, if he be worthy...
Worthy. Not powerful. Not royal. Not deserving.
Worthy.
And what made someone worthy wasn't sitting on a throne or winning battles or ruling realms. It was something simpler. Something harder.
Sacrifice.
"GO!" Thor bellowed at Jane Foster and the agents huddled behind the wreckage. "GET AWAY FROM HERE! NOW!"
Then the mortal who had lost his godhood turned and ran — not away from the divine explosion, but directly toward it. Straight into the energy storm, straight toward the crystal coffin that was seconds from shattering, with nothing but a human body and the desperate certainty that this was what he was supposed to do.
"JAKE! I'M COMING!"
He hit the storm wall and the energy tore at him — burning his skin, ripping his clothes, trying to throw him back with the casual violence of a hurricane swatting at a leaf. He pushed through anyway. Because that's what Asgardian warriors did. They pushed.
The moment Thor's hands touched the crystal coffin — the moment his mortal body committed to the sacrifice with no expectation of survival—
Something stirred in the crater behind him.
Mjolnir.
The hammer that had been gray, dead, drained of every spark of divine energy — the hammer that had rejected its master, that had sat lifeless in the dirt like a discarded tool — trembled.
Then shook.
Then launched.
WHOOOOSH—!
A streak of silver light crossed the battlefield faster than the eye could track, screaming through the air with a sound like the sky tearing open—
—and slammed into Thor's outstretched hand.
KRAKA-BOOOOOM!!!
Thunder. Real thunder. Not the atmospheric kind — the divine kind. The kind that came from somewhere beyond the sky, beyond the atmosphere, beyond the nine realms themselves. A pillar of golden lightning descended from the heavens and struck Thor like the finger of God pressing the reset button.
The mud evaporated. The rags burned away. And in their place — silver scale armor materialized across his body, gleaming and ancient and alive. A red cape unfurled from his shoulders, snapping in a wind that existed only for him. His eyes blazed electric blue, and power — real power, Asgardian power, the birthright of the son of Odin — flooded back into every cell of his body.
Thor, God of Thunder. Returned.
"FOR ASGARD! FOR EARTH!"
Thor swung Mjolnir and became lightning itself — a whirlwind of divine energy that slammed shoulder-first into position beside Jake's crystal coffin. But he didn't attack the containment. He did something smarter.
He pressed Mjolnir flat against the coffin's cracking surface.
"DIVERT THE FLOW!"
Mjolnir became a lightning rod for divine power. The catastrophic energy that had been seconds from shattering the crystal and leveling everything within five kilometers found a new path — out. Guided by the hammer's enchantment, the destructive force transformed into rivers of golden light that flowed up through the weapon, through Thor's arm, and erupted skyward.
BOOM-KRAKA-RUMMMMBLE!!!
A pillar of energy — so bright it turned night into day across the entire Western Hemisphere, so powerful it registered on seismographs in Japan — punched through the atmosphere and kept going. The clouds didn't just part. They vaporized in a hundred-mile radius, leaving a perfect circle of clear, star-filled sky above the New Mexico desert.
Ten seconds later.
Silence.
The kind of silence that follows something so loud the world needs a moment to remember how sound works.
Where the S.H.I.E.L.D. base had been, there was now a crater. Dozens of meters deep, the edges fused into glass by the heat, still steaming gently in the cool desert air.
At the bottom of the crater, two figures.
Thor, God of Thunder, stood in full Asgardian armor — silver scales, red cape, Mjolnir still smoking in his grip. His chest heaved. His eyes were bright. He looked like a man who'd just been brought back from the dead, which was essentially accurate.
Opposite him, Jake Rivers lay flat on his back on the glassified ground, fully human, soaked in sweat, every muscle in his body screaming in protest. The fusion had burned through its five-minute timer with seconds to spare, and the detransformation had left him feeling like he'd been put through a washing machine filled with gravel.
He raised one hand and gave Thor the middle finger.
"Next time... you want me to hold a divine bomb for you... could you maybe show up before the last three seconds?"
Thor stared at him.
Then the God of Thunder threw his head back and laughed — a full, booming, genuine laugh that echoed off the walls of the crater and sounded like it hadn't been used in a very long time.
"My apologies, friend." Thor walked over and extended a hand — a god's hand, crackling faintly with residual lightning. "The hammer needed a moment to... recharge. But I must say — that diamond form of yours is remarkably tough."
Jake grabbed the hand, let the literal God of Thunder haul him to his feet, and spent a moment brushing glass dust off his ruined suit.
"Alright, enough bonding."
He pointed at the sky, where the last traces of the Bifrost vortex were fading into nothing.
"Your brother is probably throwing a tantrum right about now. I'm guessing this particular show is over?"
At that moment, fifty meters away, Tony Stark finally extracted himself from a sand dune. His Mark V was barely holding together — one arm hanging limp, half the faceplate missing, the arc reactor flickering like a candle in a draft.
He looked at the two figures standing at the center of the crater — a teenage alien shapeshifter and a Norse god who'd just been rebooted by his own hammer — and let out a long, exhausted breath.
"JARVIS."
His voice was hoarse.
"Archive all data on that red crystal four-armed form. Codename..." He paused, watching Jake and Thor silhouetted against the stars through the cleared sky. "...Godslayer."
Another pause.
"And order them the best barbecue delivery in New Mexico. On me."
