Midtown Manhattan – A Battlefield of Giants
The crater in the street had swallowed an entire intersection. Pavement crumbled beneath the weight of two titans locked in savage war. Hulk and the HYDRA-engineered dark green monster clashed again, trading bone-shaking blows, their roars loud enough to shatter glass four blocks away.
The creature—the Gamma Aberration which supposed to be abbormination, as later files would call it—was bigger now, veins bulging, its skin cracked like a dried-out tank shell. The corrupted HYDRA symbol on its chest pulsed with dark red energy.
From an alleyway near 44th Street, hidden behind a burned-out food truck, Kai watched.
The city was in ruins. People fled in every direction. Sirens blared. A distant radio crackled with military panic.
> "Evac routes blocked. We've lost air control—repeat, DO NOT engage. Let Hulk contain the threat."
But Hulk was struggling.
Pinned beneath a crumpled dump truck, he grunted and growled, trying to shove it off. The Gamma Aberration was on him, fists like hammers, slamming down again and again.
BOOM. BOOM. BOOM.
Blood. Even Hulk's healing couldn't keep up.
Kai looked down at the Omnitrix. It glowed in sync with his heartbeat.
He couldn't just watch.
But he couldn't risk being seen either. Not yet. Not in front of live news drones and panicked civilians. His secret had to stay secret.
He turned into the shadows, raising his arm.
Click.
Spin.
SLAM.
The transformation burst outward with a pulse of green light—quick, contained, just behind a shattered wall.
The world grew smaller around him.
Kai's bones stretched, muscles bulged, and tan armor plates erupted across his body. His jaw lengthened into a brutish snout, claws crackling through fingerless gloves. His voice deepened into a gravel growl as his shadow stretched across the ruined sidewalk.
Humungousaur emerged from the alleyway.
Thirteen feet of raw prehistoric power.
He let out a low, rumbling growl and cracked his knuckles.
"Humungousaur".
It was time.
On other side.
The Gamma Aberration raised its arms for a final blow—then froze.
A blur of muscle and force slammed into it from the side, sending both it and Hulk rolling into separate directions.
CRACK!
The ground split beneath Humungousaur's landing. Dust rose around him like a curtain. He stood between the two giants now—part savior, part storm.
Civilians screamed again, this time in confusion. From rooftops and shattered cafes, they stared.
"Is that… another Hulk?!"
"No—what the hell is that?!"
"Someone's helping him!"
But Humungousaur said nothing.
No press. No name. Just fists.
The Gamma Aberration howled in anger, charging with a shoulder-first lunge.
Kai met it head-on.
BOOM!
The two monsters collided like tectonic plates. Concrete sprayed like fireworks. Humungousaur grabbed its arm and twisted, slamming his elbow into the mutant's side and tossing it into a wrecked city bus.
KA-CRASH!
Dust swallowed the street.
Hulk finally climbed to his feet, blood dripping from his temple. He blinked at the new arrival, confused… but not hostile.
He gave a grunt of respect.
Kai nodded back, panting slightly.
They charged together.
Double Destruction
Now it was two against one.
Hulk took the left flank, roaring and slamming a knee into the monster's thigh. Kai—Humungousaur—rolled to the right, jumped, and brought both fists down on the Aberration's shoulders, sending it to one knee.
It retaliated with a blast of gamma energy from its chest—a crude, unstable explosion that singed the air and threw Kai into a storefront.
CRASH!
Glass and wood exploded.
Kai coughed, shook the dust off, and barreled forward again. He ducked a wild punch, pivoted, and grabbed the creature's tail, swinging it like a wrecking ball into the side of a parking garage.
Above, the military drones filmed the chaos.
"Unidentified second giant on-site—repeat, second unknown gamma-class entity assisting Hulk!"
"Do we have visual ID?"
"Negative. No SHIELD records. No known gamma signature. Origin: unknown."
And that was just how Kai wanted it.
The Gamma Aberration, now raging blindly, grabbed a light pole and swung it like a sword. It clipped Hulk across the shoulder, then stabbed toward Kai.
Kai dodged, ducked, and caught the pole mid-swing. He yanked it, snapping the metal in half and throwing it aside.
Then, with a roar, he jumped, shouldered the Aberration in the gut, and lifted it clean off the ground.
WHAM!
SLAM!
He brought it down, spine-first, across a broken taxi.
The monster writhed, groaned.
But then—one last desperate move—its back glowed red with gamma corrosion. The HYDRA brand pulsed violently.
It was going to explode.
Hulk & Kai – The Final Hit
Hulk lunged.
Kai met him mid-sprint.
Together, they leapt.
Hulk swung high.
Kai swung low.
BOOOOM!!
Their fists collided with the creature's chest and skull simultaneously, dispersing the unstable energy in a shockwave that shattered every window within three blocks.
The Gamma Aberration went limp.
Then still.
Then… crumbled.
Ash.
The HYDRA mark hissed as it burned away into nothing.
Aftermath – Smoke and Silence
The air stilled. Wind swept through the rubble.
Hulk stared at Kai.
Kai stared back.
A moment passed.
No words.
No names.
Hulk gave him a slow, knowing nod. Respect.
Then, with a grunt, Hulk turned and leapt away into the horizon—thoom-thoom-thoom—gone as suddenly as he arrived.
Kai looked around.
Civilians began to step out from behind cover.
Cameras pointed toward him.
Drones hovered.
He had seconds.
He ducked into the alley. Fast. His claws scraped concrete as he stumbled behind cover.
SLAM!
Green light burst behind the wall.
A flash.
Then silence.

Minutes Later – Rooftop Above
Kai stood alone, back in his human form, hood drawn up.
He looked down as emergency crews began tending to survivors. People stared in awe at the wreckage. Some clapped. Some cried. Some whispered about "the other green monster" who helped the Hulk.
No one knew who it was.
No one saw his face.
And that was exactly the point.
He tapped the Omnitrix lightly.
"Nice work," he whispered.
The watch blinked once.
Then returned to silent green.
