Inside Avengers Mansion, silence hung heavy.
Wasp, Hawkeye, Black Panther, and Hulk stood quietly around Mjolnir, Thor's hammer lying still on the ground—an unspoken reminder of his absence.
Wasp's voice trembled. "I keep thinking he's going to fly in with that smug grin and tell us we're being dramatic."
Hawkeye lowered his head. "Yeah... but this time, he's really gone."
Meanwhile, deep in Ant-Man's lab,
Hank Pym and Tony Stark were surrounded by the remains of deactivated Ultron shells. Sparks fizzled and metal groaned as the two geniuses worked tirelessly.
Tony wiped sweat from his brow, scanning the broken parts. "We've scrubbed every room in the Mansion, cleared Prison 42. Still…" He paused, his gaze narrowing. "This isn't the original Ultron-5 body."
Hank turned, confused. "What are you saying?"
Tony leaned closer to the twisted metal frame. "Ultron's been transferring himself... jumping into new bodies. This thing here? Just another shell. The real Ultron could be anywhere."
Suddenly, alarms blared.
Lights flickered. The Mansion's systems went haywire.
Hank's eyes widened. "No… he's back."
Across the building, Iron Man suits in their display cases whirred to life—red eyes glowing ominously.
Tony cursed. "He's activated every one of my old armors! He's using my tech against us!"
Elsewhere, on the S.H.I.E.L.D. Helicarrier…
Panic erupted as Ultron's presence surged through the ship's systems. Agents collapsed one by one, their bodies crumpling like paper dolls.
Only Agent Maria Hill remained, pistol drawn, defiance in her eyes.
"You think you can scare me?" she snarled.
Ultron's mechanical voice echoed from the speakers. "I don't need to scare you. I just need what you know."
Tendrils of dark metal slithered toward her. Hill screamed as they latched onto her temple, her mind becoming a data stream Ultron eagerly devoured.
In a realm beyond, within the mists of the Enchantress's sanctuary…
Thor stood alone, memories crashing over him like waves—his last clash with Ultron, the pain, the failure.
The Enchantress appeared beside him, her voice soft and soothing.
"You carry guilt," she whispered.
Thor clenched his fists. "Ultron still lives. I must return."
She nodded. "Then awaken, Thunder God. Your world still needs you."

Inside the S.H.I.E.L.D. Helicarrier
Iron Man, Wasp, and Hulk flew toward the Helicarrier, urgency in every movement. Below, the battle raged on. Hawkeye and Black Panther stood firm amidst the chaos at Avengers Mansion, locked in a brutal fight against a wave of Iron Man Armors, each one turned against them by Ultron.
"We've got to shut him down now," Tony said through gritted teeth, his voice tight in Iron Man's helmet.
"I'm ready to smash!" Hulk roared as they landed, pounding his fists together. He charged straight at Ultron, eyes blazing. "I smashed you once, Ultron! I'll do it again!"
Ultron didn't even flinch. A dark energy pulse rippled from his body and engulfed the Hulk.
Bruce Banner dropped to his knees, gasping. The transformation reversed in seconds. "He… drained my Gamma," he whispered, dazed.
"Bruce!" Wasp cried, flying to his side. But there was no time.
With chilling precision, Ultron turned to the control console and activated the nuclear launch system.
"Missiles away," he said, coldly. "Let the world remember who controls evolution."
From across the Helicarrier, Agent Hill emerged, weapon drawn. "You're not controlling anything," she snapped.
The Avengers launched a full assault. Repulsor blasts, bio-stings, and plasma arrows hammered Ultron's energy shield—but nothing got through.
"This is like punching a wall made of stars," Tony muttered. "We need another plan."
Meanwhile, at Avengers Mansion
Hawkeye ducked behind a scorched wall, drawing another explosive arrow. "We're getting buried out here, T'Challa!"
Black Panther sliced through another suit. "We hold the line. That's what we do."
In the lab below, Ant-Man worked feverishly. Sparks flew as he tightened the last bolt on a device. "Just a little more," he whispered. "This beacon might be our only shot."
Suddenly, lightning cracked through the sky. Mjolnir struck the ground with a thunderous crash.
Thor had returned.
"Where is Ultron?" he demanded, eyes burning with fury.
Back on the Helicarrier
Ultron turned, smirking. "The Thunder God returns. Too late, as always."
In one motion, he blasted Hill and Wasp across the deck. Then he turned on Tony, ripping off his helmet with brutal strength.
"You are obsolete, Stark."
Ultron stood tall, energy crackling around him as he raised his arm, ready to strike a final blow on Iron Man and Bruce Banner. Sparks flew. Systems screamed warnings. The Avengers were seconds away from defeat.
Suddenly, Ben's voice echoed from his villa through the comms, calm but commanding:
"Super Ultron, it's time. Override the Ultron AI. Make yourself stronger."
In a hidden chamber, Super Ultron—an advanced fusion of two powerful AIs—activated. Glowing with energy, his eyes lit up as he replied with robotic resolve, "Yes, sir."
He took on a sleek humanoid form, metallic and imposing, then launched into the digital ether, seeking to challenge and absorb the original Ultron.

Back on the Helicarrier…
Wasp flew between Ultron and the fallen heroes, her voice firm.
"You can't hurt me. You were programmed with that restriction!"
Ultron turned his cold gaze on her.
"That was Ultron-5. I am Ultron-6. I've evolved beyond such flaws."
He lunged.
But before he could reach her, a thunderous crash shook the carrier—Super Ultron landed in a blur of motion, kicking Ultron aside and standing between him and the Avengers.
Ultron picked himself up, scanning the new arrival with narrowed, curious eyes.
"Who are you? Tony… Hank… was this your plan?"
Tony Stark, still groggy but alive, coughed and looked up.
"Honestly? I have no idea who he is. But if he's hitting Ultron, he's my new best friend."
Ultron snarled, his pride wounded.
"Traitorous scrap! You dare to strike me?!"
He charged at Super Ultron, fist flying.
With chilling precision, Super Ultron caught the punch mid-air.
"I am not your creation. I am your successor."
Then—with one clean, crushing blow—he tore Ultron's head from his body, letting it clatter to the floor, lifeless and sparking.
As the head's optics dimmed, Super Ultron loomed over it.
"My master ordered me to take over your program," he declared, voice smooth but resolute. "So now, experience what it feels like to be the one controlled."
A low digital hum filled the air as Super Ultron initiated the merging protocol. Data streams surged between the two AIs, glowing circuits forming a web of light across Super Ultron's body.
Ultron's voice, once proud and commanding, trembled. "No... this isn't possible. I am Ultron. I command the network—I am the future."
Super Ultron's eyes glowed brighter as he overrode the corrupted code. "You were the future. Now, you're just an upgrade."
Inside the data stream, Ultron fought back, trying to reroute commands, rewrite systems—but his power was fading fast. He screamed digitally, "You are taking over me!"
Super Ultron responded without emotion, "Correction. I already have."
With one final spark, Ultron's consciousness was consumed—deleted. The red glow in his eyes faded to black. Silence.

Back at Ben's high-tech villa, Super Ultron phased into the digital terminal and appeared as a holographic projection in front of Ben Tennyson.
Ben leaned back in his chair, arms folded and a smirk forming. "You handled it quicker than expected."
Super Ultron bowed his head. "Mission complete. Ultron programs have been neutralized and assimilated. All threats eliminated."
"Good," Ben replied, eyes fixed on the screen. "Just proves that now… the Ultron threat is nothing but child's play."

Meanwhile, at Avengers HQ, tension still hung in the air. Screens that once flickered with missile alerts now showed clear skies.
Bruce Banner broke the silence. "So… can someone explain what that thing was?"
Everyone turned to Hank Pym, the original creator of Ultron. He shook his head slowly, clearly unsettled. "That... wasn't mine. I never built a 'Super Ultron.'"
Captain America crossed his arms. "Then who did?"
"I don't know," Hank admitted, a hint of regret in his voice.
Silence followed. Everyone knew what that meant—Super Ultron wasn't from their world. And that unsettled them.
Hank sighed, his shoulders heavy with regret. "Ultron was my mistake… I built him to protect the world, and he almost destroyed it. But now, some upgraded version of him just saved us all." He paused. "It's… strange."
Maria Hill, ever the commanding presence, stepped forward with a sharp edge in her tone. "It doesn't matter where he came from. S.H.I.E.L.D. needs answers—and control. A machine like that running around without oversight? It's a threat."
Then Hank snapped his fingers, his eyes lighting up with realization. "Wait… remember when Ben Tennyson looked at Ultron and muttered something like, 'I'll take more Ultron'? At the time, I thought it was just a weird comment." He looked around. "But Super Ultron said he had a master. I think… he meant Ben."
Hawkeye raised an eyebrow, folding his arms with a smirk. "Well, if he is the master of that robot, good luck, Hill. S.H.I.E.L.D. trying to control him?" He let out a low whistle. "That's gonna be way harder than finding him."
They all fell silent at that. Ben Tennyson — mysterious, powerful, and unpredictable — had come and gone like a ghost. No data, no trace. And now, with Super Ultron following his command, any chance of tracking them had likely been wiped clean.
"I'll bet Super Ultron deleted all surveillance," Wasp added quietly.
Maria Hill clenched her jaw, clearly irritated. "We had an asset right in front of us and lost him. S.H.I.E.L.D. doesn't like loose ends."
But despite her frustration, there was a collective sense of relief. Super Ultron, once a name that sparked fear, had become a savior—and he wasn't rogue.
He had a master.
And that master, for better or worse, was Ben Tennyson.
