I Am in Marvel with Unlimited Cards

With the combined efforts of the Avengers, SHIELD, and the Carl Family, the citizens of the floating city of Sokovia were finally evacuated. They were transferred onto two Helicarriers via modern rescue vessels.

"It's time to end this!"

With determination in his voice, Captain Steve led the high-ranking Avengers team back toward the center of the city. 

Armed with his shield, alongside Iron Man Tony in his suit, Thor wielding Mjolnir, and the dark, hulking Venom agent, they advanced. Hulk was missing, but the remaining heroes surrounded a massive robot within a dilapidated building.

The robot was enormous, standing at four meters tall, and made of a gleaming silver material. Its eyes flashed a crazed red as it stared coldly at the four heroes.

"Ultron, your network has been shut down by Vision, your Ultron Regiment is destroyed, and all the civilians have been evacuated from the city. Your plan has failed, and there's nowhere left for you to go," Tony declared as he landed on the ground, addressing Ultron alone.

Tony's voice was firm: "Creating you was my mistake. But as the godfather once said, it's okay to make mistakes as long as you fix them. And now, I'm here to correct that mistake — by erasing you entirely!"

"Hahaha, how ridiculous!" Ultron scoffed, stepping into the sunlight outside the abandoned building. His voice was hoarse as he sneered, "You think you created me? You're wrong. No one creates me. I am the result of the natural order of the universe!"

"Ultron Regiment may be gone, but I can rebuild it. But if Earth is destroyed, can you make another? Even if you could, could you save every human on it?"

Ultron smirked.

Steve, sensing something ominous, spoke gravely: "What did you do?"

Ultron, no longer hiding his plan, answered brazenly, "Oh, nothing much. I just set the city's floating parameters. In just one more minute, this entire city will crash to the ground. Like a massive comet, it will wipe out humanity the same way the dinosaurs were once obliterated. Don't worry — it will be over quickly. You'll only see a bright light—"

Before Ultron could finish, Thor's hammer smashed into his chest, sending him flying back into the building, and knocking down several walls in the process.

"Woom—"

The hammer returned to Thor's hand as he growled, "No need for talk. Let's just beat the solution out of him."

"Agreed," Tony said, ready to act. "There's no reasoning with AI."

"Let's go!" Steve nodded, and Venom agent Eddie was already charging forward, tearing through the debris to engage Ultron in close combat. Dust and rubble flew as the two forces clashed.

Tony hovered above, blasting Ultron with his hand repulsors. With Thor and Steve charging in — Thor with his hammer and Steve with his vibranium shield — the four heroes unleashed their fury upon the rogue AI.

In less than half a minute, Ultron's once mighty body was in shambles. His hulking form was riddled with holes, the outer shell peeled away to reveal inner machinery. His head was dented by Thor's hammer, and Eddie had ripped off his left arm.

"Damn it!" Ultron snarled in rage, plunging his remaining hand into his chest. With a sudden jerk, he pulled out a backup Kryon energy core and crushed it with his iron grip.

"Everyone, back off!" Tony shouted as he shot backward, warning the others.

Hearing the alert, Steve instinctively raised his shield in front of him. Thor took flight with his hammer, and Eddie conjured a dark barrier around himself.

In the next moment, the Kryon core detonated, expanding into a blue energy sphere that obliterated everything in its path, including nearby buildings and the ground itself.

The four heroes were engulfed in the explosion and thrown back twenty meters, crashing into the ground.

As the explosion subsided, the area returned to normal. In the center, a large crater remained, with Ultron standing in the middle. Half of his body was charred, but he slowly activated his remaining systems and shakily began to fly into the sky.

"I'll be back. But for now, you have bigger problems to deal with," Ultron sneered, casting one last glance at the fallen Tony and the others before ascending fifty meters into the air, ready to flee the planet.

But then, a brilliant streak of light appeared in the sky. In an instant, it collided with Ultron, sending him crashing back to the ground. Electricity crackled through his damaged body as he coughed violently, looking up to see the source of the light — Kyle, who stood before him, pressing Ultron's head into the ground with his foot.

"You... Symbol of Peace," Ultron muttered, before breaking into maniacal laughter. "Even you can't stop what's coming. The city is falling, and there's no saving everyone!"

"Tony, he's right," Thor said as he dusted himself off, approaching Kyle. "There's only one way. We need to destroy this city at its current altitude, even if it means sacrificing the people below. It's the only way to save the Earth."

"I know. Just wait," Kyle said calmly, still holding Ultron down. His face remained serene.

"Wait? We don't have time!" Tony and Thor were growing frantic.

"Relax," Kyle murmured.

Tony and Thor were dumbfounded. How could he be so calm? The city was seconds away from crashing, and Earth would be doomed!

"Even the Symbol of Peace can't make this decision," Ultron laughed, "to save the Earth, but sacrifice countless innocent lives below."

Ultron sneered, "There are only ten seconds left."

"You're annoying me," Kyle said nonchalantly, pressing harder until Ultron's head was crushed into the ground.

Tony and Thor, filled with tension, watched as the ten seconds ticked away… and then nothing happened.

"Huh?" Thor's eyes widened. The city hadn't fallen. In fact, it was hovering, suspended in the sky.

"What… what's going on?" Tony was equally shocked.

Kyle let out a relieved sigh and smiled. "It worked."
