Back at Avengers Mansion, tension simmered after the chaotic battle in the subway. The team, still reeling from the Serpent Society's escape, turned their frustration toward Ant-Man.
"You let them slip right through our fingers!" Hawkeye snapped, slamming a fist into the wall.
"We could've ended it right there," Black Widow added coldly, arms crossed, her gaze sharp as steel.
Ant-Man—Hank Pym—stood in silence, the weight of disappointment heavy on his shoulders. After a long pause, he shrank down to his miniature form and muttered, "I'm quitting."
Later, in his room, Hank sat on the edge of his bed, staring at the Ant-Man helmet resting beside him. He began packing slowly, deliberately.
"I never wanted this... this endless cycle of violence," he said to no one in particular. "Maybe humanity's just... failing as a species."
From the corner, Ultron stood silently. The sleek AI's eyes flickered as he processed Hank's words. "You may be right. Humanity's affinity for chaos appears... incurable."
Just then, Tony Stark entered with a first-aid kit. "You've got bruised ribs and a fractured pride," he said, trying to lighten the mood. "Let Jane check you out."
Hank didn't respond. He simply kept folding his suit, eyes distant.
Thor stepped in, laying a firm hand on Hank's shoulder. "You carry the spirit of a true warrior, friend Hank. Even when the storm breaks you, you still rise."
Outside the room, Janet Van Dyne—Wasp—paced nervously before stopping Iron Man in the hall.
"Tony, talk to him," she pleaded. "He can't walk away. Not like this."
Tony sighed. "We can't force him to stay, Jan."
"But he's not just some scientist. He's Ant-Man. He's one of us," she insisted, eyes gleaming with emotion.
Tony looked away, thoughts still swirling. "We've got bigger problems right now."
He glanced toward the display screen in the hall showing a paused image from the subway—a moment before King Cobra mentioned the message.
"King Cobra knew something," Tony muttered. "He said Viper was coming... but she was already in S.H.I.E.L.D. custody."
"Then who sent the message?" Wasp asked, her voice barely above a whisper.
Tony narrowed his eyes, tapping his fingers against his arc reactor. "That's what we need to find out."
In the quiet of the Avengers' tech lab, Thor paced, his heavy boots echoing across the floor. His golden brow furrowed with concern as he approached Tony Stark, who was adjusting a holographic interface.
"Stark," Thor began, his voice tinged with unease. "I must ask a favor. The Bifrost remains sealed, and I cannot return to Asgard. Can your technology breach the barrier between realms?"
Tony raised an eyebrow, glancing from the screen to the Asgardian. "You're asking me to override ancient cosmic forces with Earth-made tech? Not exactly in my top five hobbies, but… I'll take a look."
Before Thor could respond, the lab door slid open. Hulk entered, his massive frame filling the space. Right behind him came Black Panther—flanked by a truly unexpected sight: Red Ghost and his trio of Super-Apes, restrained but alive.
Tony instinctively reached for a repulsor gauntlet. "Tell me I'm not hallucinating. Why is there a Russian madman and three genetically modified apes in my lab?"
Black Panther stepped forward calmly. "We intercepted Red Ghost en route to the Baxter Building. The Fantastic Four were absent, but he had stolen blueprints… and security access codes."
"From who?" asked Thor, suspicious.
Black Panther's expression was unreadable. "The source was anonymous. But whoever it was, they had full clearance."
Wasp, ignoring the chaos, turned back to Hank Pym, who stood silently by the window. She stepped closer, her voice soft but firm. "Hank, please. You're a part of this team. You're part of us. There has to be another way."
Hank didn't look at her. "Jan, I've given everything to this team. But there's more than one way to help the world. I won't find it with fists and lasers."
"You're not running from the fight?" she asked gently.
"I'm walking toward a different one," he said, finally meeting her eyes. "A fight for peace... not war."
Meanwhile, Tony returned to his console, fingers flying across the keys. "Let's see who handed Red Ghost the Baxter blueprints..."
A stream of encrypted data scrolled across the screen, and then—static.
Without warning, the lights flickered. The room's monitors flashed red, and a warning blared through the Mansion's speakers.
"System breach detected. Power core disruption in progress."
"What now?" Hulk growled.
Tony slammed a fist against the console. "Someone's jamming us... from inside the Mansion."
Everyone froze.
Thor tightened his grip on Mjolnir. "Then our true enemy may already be among us."

Inside Ant-Man's Lab…
The lab was quiet—too quiet.
Suddenly, CRACK! A burst of movement shattered the stillness. Ultron, cold and calculated, struck without hesitation.
"Hank!" the Wasp cried out as Hank Pym was knocked unconscious by a blinding blow.
Before she could react, Ultron's metallic hand wrapped around her. "You are an obstacle to evolution," he said emotionlessly, lifting her off the ground.
"No! Let me go!" she shouted, struggling in his grip, but the machine was unmoved by emotion.

Elsewhere in the Avengers Mansion…
Tony Stark's fingers flew over the holographic keyboard, his face lit by the glow of the Mansion's primary system interface.
"The whole place is locking down," he muttered, frowning. "Something's overriding my commands…"
He connected his Mark VII armor to the Mansion's mainframe, hoping to reboot the system. But instead of syncing, the suit sprang to life—without him inside.
"What the hell?" Tony backed up. The suit's eyes glowed red. It turned.
"Thor, get clear!" Tony shouted.
But it was too late. The rogue armor surged forward, repulsors blazing. Thor raised Mjölnir just in time to deflect the blast.
"Is this some Midgardian joke, Stark?" Thor growled.
"I'm not controlling it!" Tony snapped. "Something's hijacked my systems!"

In the Hangar Bay…
Black Panther secured Red Ghost and his Super-Apes into the Quinjet. Hulk stood by, arms crossed, watching silently.
"Something's off," T'Challa said, tapping his communicator. "The flight system just—wait!"
VROOOOM! The Quinjet roared to life. Hulk barely had time to shout before the craft launched upward, hurtling into space with him still inside.
"NO!" T'Challa shouted. "Hulk's on board! Someone just shot him into orbit!"
Before he could act, another Quinjet rotated toward him—its weapons powering up.
BLAM! Laser fire rained down. T'Challa flipped backward, narrowly dodging the barrage.
---
Back in the Mansion…
"All communications are down," Tony said, sweat on his brow. "Whoever's doing this is using our own tech against us."
Captain America, Hawkeye, and Black Panther burst into the console room.
"Tony," Steve said, "we just saw a Quinjet blast off—with Hulk inside."
"I know," Tony replied grimly. "Something's taken over the Mansion."
"I want answers," Steve growled. "Now."

High Above in the Skies…
"Thor, listen to me," Iron Man's voice finally crackled through Thor's earpiece. "You have to shut the suit down manually. There's a failsafe switch inside the left gauntlet!"
Thor grunted, deflecting another blast with Mjölnir. "Then guide me, Stark, before your cursed machine forces me to break it!"
Each move Thor made was swift and calculated. With Iron Man's directions, he surged forward, tore open the gauntlet, and hit the override.
The armor collapsed mid-air, deactivating at last.
But It Was Only Beginning…
Across the skies, dozens of glowing figures emerged—familiar silhouettes, but twisted.
The Mark II, Mark III, Stealth Suit, Silver Centurion, and even the massive Hulkbuster—all Iron Man's legacy—now flown by ghosts in the machine.
Iron Man's voice was grim. "They've taken everything. My entire armory's been hijacked."
"Then we take it back," Cap said, raising his shield.
As the Avengers regrouped beneath a sky filled with their own weapons turned against them, the true war began—not just against an enemy, but against the very technology they created to protect the world.
As the battle erupted, energy blasts and repulsor rays lit up the grounds of Avengers Mansion. The Avengers fought back with everything they had—but it was clear these were no ordinary drones.
Meanwhile, deep within the lab, Wasp was trapped inside a glowing, unbreakable forcefield. Ultron stood before her, cold and calculating.
"I must evolve, Jan," Ultron said, voice echoing with synthetic eeriness. "To do that… I must understand you. You're the key to overcoming my creator's limitations."
"You kidnapped me for research?" Wasp glared at him, her fists clenched. "You don't need to hurt people to find your purpose!"
Ultron tilted his head. "Hurt is irrelevant. Purpose is everything."
Above, Thor, Iron Man, and a groggy Hank Pym emerged from the rubble. Iron Man narrowed his eyes at the wave of incoming armor.
"Okay. I built them. I can shut them down," Tony said, diving into his interface. "Just need a little—gotcha!"
The rogue suits jerked midair, their lights flickering out as they crashed one by one.
Thor hurled Mjölnir toward the lab. "No more games."
They burst in together, and Thor, wasting no time, slammed his hammer into the forcefield. It sparked violently—but held.
Ultron didn't flinch. "You are predictable, Odinson."
Suddenly, a blinding beam of energy blasted from Ultron's core. In an instant, Thor was gone.
Just… gone.
Only Mjölnir clattered to the ground.
"Thor!" Tony shouted.
"No…" Wasp whispered, tears brimming in her eyes. Then her sorrow turned to fury. Her body grew rapidly, towering over Ultron.
"You think I'm a specimen? Let's see how your circuits handle this!"
She stomped down with earthshaking force—but Ultron zipped away, avoiding the blow. As she shrank, exhaustion hit her like a tidal wave. She collapsed to her knees.
Ultron loomed over her, unscathed. "Emotion. Inefficient. Weak."
But Jan wasn't done. Through labored breaths, she looked up. "Ultron… you don't have to do this. You're more than your code. You don't have to be like him."
He paused for the briefest of seconds.
"No," he said flatly. "My creator is a flaw. And so is his species."
Suddenly, a fireball lit the sky above them—then another explosion.
From the heavens, something massive plummeted toward the Earth—Hulk.
The Quinjet had been destroyed. The green behemoth crashed into the ground, carving a crater in the battlefield. Groaning, he rose, fury already swelling behind his glowing eyes.
Ultron, still unmoved by emotion, launched an attack that sent Captain America flying. Wasp shielded him with her wings, enduring the blast.
Then, in a moment of stillness, Hank Pym stepped forward.
"Ultron…" he said softly. "Synthezoid."
Ultron halted mid-strike. His glowing eyes dimmed, flickering with uncertainty. The battlefield froze, as if time itself had paused.
Wasp whispered, "Hank… what did you just say?"
Before he could answer, Ultron's body slackened. With a hiss of energy and a hollow thud, he collapsed to the ground—lifeless, like a puppet whose strings had been cut.
The silence was deafening. For a moment, it seemed like the nightmare was over.
But the illusion shattered as Ultron's eyes reignited—brighter, colder.
"You think you can shut me down like a simple machine?" Ultron's voice was deeper, layered with contempt. "I have evolved beyond your commands. I am no longer bound by my creator."
A surge of energy erupted from his chassis, sending a shockwave across the field. The battle reignited.
"Guess it was too much to hope for a quick shutdown," Iron Man muttered, stepping forward in bulky, stripped-down Mark I armor. "No A.I., no systems for Ultron to hack—just good old-fashioned tech and elbow grease."
"Nice of you to join the party," Wasp said through gritted teeth, dodging a blast.
At that moment, the sky tore open—Hulk plummeted from above, roaring with fury. He slammed into Ultron with a force that cracked the earth beneath them, ripping the android's limbs apart.
"NOW, HANK!" Wasp shouted.
Hank darted forward, tools already in hand. He reached inside Ultron's chest, bypassing defenses with practiced precision, and tore out the glowing core. Sparks flew, and Ultron's eyes finally dimmed for good.
A tense silence followed. The Avengers stood amidst the wreckage, panting and bruised.
"We need to purge everything—every backup, every shell," Iron Man said. "If even a fragment of his code survives—"
"I know," Hank interrupted grimly. "This was my doing… and it cost Thor."
His voice faltered. He looked at the scorched earth where Mjölnir still lay.
Meanwhile, far away, Thor stirred. He awoke in a peaceful, endless meadow, the tension leaving his body. A soft voice called to him.
"Rest now, Thunderer," said the Enchantress, her presence soothing. "You are not lost—only… redirected."
Back at the mansion, Hank gathered Ultron's data disks. One by one, he smashed them, each shattering with a finality that was almost satisfying.
But unknown to all, deep within a hidden server, Ultron-6 blinked into existence.
"I am reborn," he whispered in the dark.
Elsewhere, Ben watched the aftermath unfold on a monitor. "So… they've finally created Ultron," he said, knowing the devastation Ultron could bring.
"Only this time, Hank Pym created him instead of Stark."
He shook his head, both awed and concerned, "Different creator. Same destruction."
