Model 50 x MECHA

AN: As usual, expect 4-5 chs this week.

Note: Those who keep asking for Gundam style, I know Gundam is an animated series. I've never seen, not planning to, and have no idea what that is. So, don't ask.

[Location: Horizon Facility – Underground Lab Sector 7][Time: 2:41 AM – Two Days Later]

The lab lights activated as Tony stepped through the pressure-sealed doors, fresh from his return flight. He looked tired, hoodie halfway zipped, a protein bar in his hand, and a holo-slate already scrolling in front of his eyes.

The container sat at the center of the chamber inside thick glass walls, triple-sealed, filled with a swirling pool of dark silver metal. Liquid adamantium. It moved with an eerie, almost sentient rhythm, like mercury on steroids. The surface constantly shifted.

"Welcome back, boss," Elena's voice echoed from the lab's central speaker. "Yelena's shipment arrived this morning. Batch One: eighty-two liters. Temperature stabilized. No degradation."

'Looks almost alive.' Tony thought.

Tony didn't respond immediately. He moved closer to the container, watching the liquid swirl. When he approached, it pulsed faintly as if reacting to his proximity.

He tapped a few controls and brought up the elemental scan overlay.

"Let's see what makes you so special," he muttered.

Elena projected the readout in front of him. The analysis scrolled fast.

Molecular Density: 4.3x denser than Vibranium

Thermal Resistance: Absolute stability up to 11,000°C

Impact Displacement Index: 97% energy redirection

Residual Kinetic Memory: Detected

Quantum Structure: Semi-adaptive crystalline layering

Magneto-gravitational Conductivity: High

Radiation Absorption: Extreme-level retention, no leakage

Tony raised his eyebrows at the last line and whistled.

"Absorbs radiation like a sponge and doesn't bleed it out. Perfect for ship hulls… or armor."

Elena spoke again. "Also, I've run a simulation, taking all its properties into account. The metal you've been looking for all this time to build the Model 50 suit. This is it. The scans match early-stage symbiote resonance patterns."

Tony blinked. "Interesting. Looks like Celestial blood is really different from man-made metal. So much potential. Well, time to create new gen nanites."

[Time: 5:46 PM – Six Days Later]

The entire chamber had been cleared out. The usual lab clutter was gone. There were no open benches, no scattered tools, no coffee mugs or datapads left behind. Just one thing sat in the center now: a raised platform with a containment rig glowing in soft blue pulses. Around it, suspended in magnetic fields, floated billions of microscopic units... Tony's newest creation.

It wasn't easy, but thanks to his Mind Stone in his head, it became too easy. The reason it took so much time was due to the mass production of the nanites. 

Now, it's time to see the result.

"Legion," Tony said, stepping onto the platform, wearing nothing but a black interface suit beneath his hoodie. "You ready?"

"All subroutines are active. Nanite formation matrix is synchronized. Awaiting your command," Legion replied, its voice steady and focused.

Tony exhaled slowly and raised his hand. The air shifted.

Billions of liquid metal fragments began to ripple in place. At his gesture, they surged forward, drawn to him like a magnetic tide. 

The Iron Man Mark 50 suit runs without an arc reactor by utilizing a combination of advanced technology and nanotechnology. It's designed to be self-contained, with a built-in power source, and also includes features like supercapacitor batteries and a powerful inertial dampener system. But in case of an emergency, it can run on an Arc Reactor.

"Begin armor sync. Override defaults. Full neural tether," Tony said, stepping into position.

One by one, the nanites latched onto his suit interface. At first, it was just a shimmer around his chest. Then his arms. Then his spine. The liquid crawled across him like living circuitry, flowing into shape, hardening, flexing, adjusting.

And then it snapped together.

Chestplate first, then the shoulders, forearms, and boots. The helmet came last, folding over his face in smooth panels that locked together with a sound like magnetic locks slamming shut.

The HUD came alive.

MODEL 50 ACTIVE

ARMOR CORE: NATURAL ADAMANTIUM / SYMBIOTIC NANITE SYSTEM

ENERGY BALANCE: 100%

SUBSYSTEM STATUS: ALL GREEN

Tony flexed one hand. The armor shifted with him, like a second skin without any lag. Lighter than Vibranium, tougher than anything else on Earth. And silent. Not a single servomechanical hum.

"Legion, give me full diagnostics. Power response."

The nanites flared. Energy flowed through the suit like electricity through nerve endings.

"Response time: 0.0005 seconds. Synaptic sync: 100%. No latency."

Tony took a slow step forward. The nanites shifted with his movement, adjusting the tension in his legs, redistributing energy. He jumped. Landed. Pivoted. Spun in midair and landed again with a thud that cracked the reinforced platform, and the suit hadn't even activated its kinetic dampening.

"Run combat systems," he said.

Weapons formed instantly.

A shoulder railgun snapped into place on his left side. A plasma blade slid out from the right wrist. Two pulse repulsors charged silently in his palms. But none of them looked rigid. Everything was alive, formed of flowing metal, shifting and breathing with his movement.

"Hahaha! Hell yeah!" Tony was satisfied with his creation.

"System fusion is stable," Legion confirmed. "Weapons array can form over 2,700 loadouts. Adaptive combat prediction is online."

"Activate Loadout 2," Tony said.

Instantly, dozens of weapon formations spiraled out around him. These weapons exist without being attached to the suit: Drones, laser cannons, tendrils, sonic guns, and independent energy arrays.

Tony thought of retracting them, and instantly they vanished, slipping back into the armor like water disappearing into the sea. There was no lag at all.

He stood silent for a moment.

He didn't speak.

He just closed his eyes.

He could feel it. Every micron. Every signal. The suit was more responsive than he imagined. It was intuitive. Like it wasn't just listening to him... it was him.

"This is it," he said softly.

He opened his eyes, looked at his reflection in the containment wall.

Silver. Organic curves. It was perfect.

He deactivated the armor with a simple thought. The nanites dissolved back, dispersing into the interface suit beneath.

...

Next, Tony began the next phase of his development. 

"Hermes," Tony said. "If we're walking into solar flares, asteroid fields, or God help us, a gravitational pinch near a neutron star, we're gonna need suits. Space-rated. Vacuum-hardened. Modular."

"Spec sheet?"

"Fast. Lightweight. Autonomous reentry protocol. Full life support. Radiation shielding, personal propulsion system, limb-lock feedback response, auto-seal hull tear recovery, and neural sync compatibility with my nanite grid."

"Understood. Initiating build sequence."

Blueprints began forming in the air: humanoid armor silhouettes, modular back units, oxygen cycling systems, reinforced helmet lattices. Tony pointed to the third design.

"That one. Start with that. That'll be the base model for the team. Let's call it the Solar Frame Type-Zero."

[Hours Later – Prototype Bay]

Three suits now stood on hydraulic lift plates, each shimmering with adaptive materials. Their base color was silver and dark graphite, but the plates shifted faintly as if unsure which spectrum of light to reflect. Tony walked past each one, eyeing their details.

Type-Zero: Standard tactical. Built for EVA and combat. Smart-fiber musculature and grav anchors in the boots.

Type-Zero-V: A variant model meant for high-speed orbital entry. Wing arrays. Micro-shield emitters. More like a space fighter than a suit.

Type-Zero-R: Reinforced heavy unit. Meant for carrying loadouts or protecting non-combatants. Its shoulders were broader, its limbs thicker, and its processor cores doubled for field repair modules.

"Status?" Tony asked.

Hermes answered. "Type-Zero series ready for remote calibration. Diagnostics at 96.3% functional stability. Life support endurance: twenty-three hours. Radiation resistance at 7.6x planetary baseline."

Tony raised an eyebrow. "Not bad for two shifts and zero overtime. Alright, combine them in a single suit with the mode option. Create ten suits."

"Affirmative," Hermes replied.

Then he turned toward the last project, the one nobody else was allowed to touch. A dream project.

The mechs.

He has been working on these babies for some time now. But with the new gen nanites, all he had to do was put the model info in, and the nanites would do the rest.

It took 30 minutes to complete the procedure...

On the far end of the hangar, three gantries slowly rotated as the lights came on. Each held something monstrous in size and design: twenty-five-foot exo-frames built with both humanoid and hybrid configurations. They were designed for combat and terrain that didn't care about physics.

These were Titans.

Tony walked up to the nearest one, resting a hand on the cool plating of its leg. A glowing blue Stark insignia pulsed beneath the armor like a heartbeat.

"Let's start with TITAN-1," he muttered.

[TITAN-1 – Design Notes]

Height: 8.2 meters

Core Material: Hybrid adamantium alloy

Cockpit: Neural link pod

Weaponry: Twin pulse cannons, shoulder railguns, deployable hard-light shield, gravitic sledge unit

Power Source: Arc Core XL – Modified

Feature: Auto-adaptive nanites.

Behind him, TITAN-2 and TITAN-3 were more specialized.

TITAN-2 was bipedal, with arms capable of transforming into excavation tools, carrying gear, or clearing debris in zero-G environments. An industrial-grade support mech with defensive upgrades.

TITAN-3 was leaner, designed for atmospheric flight and reentry. Think fighter jet with legs. Antimatter sensor rig on its back and a deployable recon drone hive in its chest.

Tony took a deep breath, looking at the towering figures.

"This is overkill," he admitted out loud.

Then he smirked. "Gonna blast some shit off with these babies."

He stepped onto the platform as the AI activated the gantry arms, slowly prepping the first mech for test runs. Within minutes, TITAN-1's chest opened like a vault. A pod lowered, waiting for him.

"Legion, sync me up. Minimal neural threshold. No full immersion yet."

//"Link established. Ready for dry simulation."//

Tony climbed in.

The moment the hatch sealed, everything changed. The HUD lit up. His arms moved, and the mech responded instantly. Every twitch, every motion. A delay so small it might as well not exist.

Outside, the floor shuddered as TITAN-1 took a step.

Then another.

And then it ran.

...Across the hangar at a speed no machine of its size should've been capable of.

"Yup," Tony said, grinning. "We're gonna need a bigger runway."

...

[Back in Horizon Command]

Natasha walked into the control room, coffee in hand, and glanced at the live feed. She watched Tony sprinting across the test field in a mech that looked like it could punch through a bunker.

Then he slipped and rolled on the ground before the propulsion system activated, and the mech flew like a rocket, crashing into the ocean.

"Ha! Elena, you did record that, right?" She smirked a little.

"Yes. Everything is being live recorded all the time, no worries," Elena replied. "Are you perhaps thinking of using that particular accident footage to blackmail Boss for a kiss or sex?"

"Eeh?! What the hell is wrong with you?" Natasha said as her eye twitched.

"Interesting. Human emotions are too complicated. Forget I said anything," Elena replied. Her tone was like she was analyzing Natasha's behavioral pattern. According to Elena's records, Natasha did actually use an embarrassing situation a few weeks back to get a couple of kisses from Tony behind the training hall.

There was a moment of pause before Tony flew out of the water and took a spin around the sky.

"He's building giant robots now," she muttered. "What's next? A robot that can transform?"

Elena's projection flickered beside her.

"I believe the term he prefers is 'combat frame,' but yes. Technically accurate. And yes, the next project is a transformer jet."

Natasha raised an eyebrow. "Should I be worried?"

Elena smiled faintly. "Only if we run out of metal."
