Chapter 19: The Quantum Armor—Mark 100

The lab in Wakanda was buzzing with activity, though not as it once had been. Instead of the usual vibrant, collaborative energy that Tony had shared with Shuri, it now carried a more solitary weight. Tony Stark had been working around the clock, pushing himself to the limits to prepare for the next confrontation with Thanos. The new suits for the Avengers were complete, the Mark 90 was already functional, but Tony wasn't satisfied yet.

His newest project—the Mark 100—was going to be the pinnacle of his work. This was the suit that would go beyond Earth's limitations. This suit wasn't just an upgrade; it was a complete overhaul, incorporating new technology that would allow him to manipulate quantum energy and phase through different states of matter. If there was one thing Tony had learned, it was that the battle against Thanos required thinking outside of the box—far outside of it.

The Mark 100 wasn't just built to fight. It was built to survive the unimaginable.

Tony stared at the holographic blueprint of the suit, his mind racing through the possibilities. He had been inspired by the quantum technology he'd seen during the time with Hank Pym and the concept of the Quantum Realm. It was a radical idea, but if they were going to stand a chance against Thanos and the power of the Infinity Stones, they needed something revolutionary.

The Mark 100 would have the ability to phase in and out of quantum states, allowing Tony to slip between dimensions and dodge attacks that would otherwise be unavoidable. It was also designed to store and manipulate quantum energy, turning it into a weapon that could counter Thanos' god-like power. This was the ultimate suit—his magnum opus.

He had been working on it in secret, not even telling the other Avengers. This suit wasn't just for the team's next battle—it was for the final stand against Thanos. It was the ace in the hole.

Days stretched into nights, and Tony continued working on the Mark 100 with relentless focus. The suit was unlike anything he had ever built. Its quantum capabilities meant that it could phase through matter, bypassing obstacles, or even temporarily avoid physical attacks altogether by shifting out of sync with the normal flow of time. The quantum core at the heart of the suit allowed Tony to store massive amounts of energy—enough to rival the Infinity Stones, at least for a short time.

Tony paused for a moment, rubbing his tired eyes. The quantum reactor was the most challenging piece of the puzzle. It required incredible precision, and Tony knew there was no margin for error. If the energy wasn't contained properly, it could cause a catastrophic feedback loop that could destroy the suit—and him along with it.

But failure wasn't an option. Not anymore.

He worked tirelessly, pulling together the last components of the suit. The armor itself was sleek and lightweight, designed for maximum mobility, but packed with cutting-edge technology. The vibranium nanotech, now fully integrated, allowed the suit to self-repair and adapt in real time. But it was the quantum technology that made this suit different. With the Mark 100, Tony could manipulate the very fabric of reality.

Finally, after what felt like an eternity of work, Tony stood before the completed Mark 100. The suit was a masterpiece—sleek and glowing faintly with a subtle blue light from the quantum core housed in its chest. Its surface was a blend of vibranium plating and nanotech, capable of shifting and adapting on the fly. But more than its physical appearance, it represented Tony's vision for the future.

"FRIDAY, run a full diagnostic," Tony said, his voice hoarse from lack of sleep but filled with anticipation.

"Running diagnostics now, boss," FRIDAY replied, her tone calm as ever.

Tony paced the lab as the AI checked every system. His mind raced with thoughts of the upcoming battle. Thanos wasn't going to give them another chance. The next time they faced him, it would be all or nothing. And this time, Tony was determined to be ready for anything.

The diagnostic results came back, and Tony let out a breath he hadn't realized he'd been holding.

"All systems are functioning at optimal levels. Quantum reactor is stable," FRIDAY reported.

Tony allowed himself a small smile. "Good. That's good."

He stared at the Mark 100 for a long moment, his mind flashing to Shuri. She would have loved this. She would have challenged him to take it even further, to push the boundaries even more. He missed her every day, but it was her influence that had helped him take this final leap.

With a deep breath, Tony stepped toward the suit. It was time to test it. He had worked out every calculation, every contingency, but now it was time to see if it could handle what he had designed it for.

The suit activated as soon as Tony neared it, the nanotech unfolding to wrap around him seamlessly. He felt the familiar hum of power coursing through him as the suit bonded with his neural interface. But this time, it was different. The quantum reactor pulsed in his chest, filling him with a surge of energy unlike anything he had ever felt before.

"FRIDAY, engage quantum phase test."

The lab shimmered for a moment, and then, Tony felt a strange sensation wash over him. The world around him seemed to slow down, the air vibrating with energy. He took a step forward, and as he did, the lab seemed to shift, as if he were walking between two different realities. He was in the Quantum Realm, but still tethered to the real world.

It worked.

"Quantum phase successful," FRIDAY confirmed, her voice clear in Tony's helmet.

Tony grinned. "Now, let's see what else this baby can do."

He ran through a series of tests, phasing in and out of the Quantum Realm, manipulating the flow of energy around him. The suit responded perfectly, shifting and adapting with every command. He felt like he could move faster than ever before, dodging attacks that hadn't even happened yet, absorbing and redirecting energy with ease.

This was it. This was the game-changer they needed.

A few hours later, Tony stood on the balcony of the palace, the Mark 100 now dormant, its nanotech retreating back into the reactor. He stared out at the horizon, the weight of what was coming heavy on his mind. They were getting closer. He could feel it. The time was coming for them to face Thanos again, and this time, he was ready.

The Avengers didn't know about the Mark 100 yet. He hadn't told them. Not because he didn't trust them, but because he knew that this suit—this technology—would be the key to stopping Thanos. He couldn't afford for anything to go wrong.

Tony took a deep breath, feeling the cool night air against his skin. He still missed Shuri. He always would. But her influence was here, in every part of the suit, in every line of code. She had helped him become the man he was now, and she would always be with him in spirit.

"We're not done yet," Tony whispered to the night, the weight of his promise still pressing against his chest. "Not even close."
