"Jiro & The Spider-Man."

-----

-----

It was dusk in New York. The lights of the Stark Tower had just flicked on.

Jiro landed outside Tony's private lab. Using his x-ray vision, he saw Tony hunched over a workbench, busy as usual, the soft blue glow of a new arc reactor shining from his chest.

"Is this how billionaires always live?" Jiro's voice suddenly rang out through the lab.

Tony spun around, dropping the tool in his hand.

"Jesus! Can't you use the front door like a normal person?" He clutched his chest. "My heart's not built for jump scares."

Jiro smiled. "The front door's not really my style."

Tony gave him a once-over, his brow slowly furrowing. "You... look different."

Yeah—spending over a day inside the sun had changed Jiro in subtle but noticeable ways.

Golden light seemed to shimmer faintly beneath his skin. His eyes gave off a soft glow in the dark. His whole vibe felt... less human.

"I got a bit of sun," Jiro said casually.

Tony poured himself a whiskey and downed it in one go. "Let me guess—not your average weekend in the Hamptons?"

"Close enough," Jiro walked over to the holographic display. "I flew into the sun."

Tony froze, glass halfway to his mouth. "You... what?"

"Literally," Jiro replied, holding out his hand.

A tiny plasma sphere appeared in his palm—an exact recreation of solar matter.

"My energy reserves are now ten times what they were."

Tony put the glass down, his expression turning serious. "I'm gonna have to redesign the anti-Superman armor."

Jiro raised an eyebrow. "It's only been a few days, and you're already working on that?"

"Scientist instincts," Tony shrugged. "But clearly, I'll need to bump the power up a few hundred levels."

Jiro laughed. "Can't wait to see it. But right now..."

He glanced out at the New York skyline. "I feel like this city could use a little help."

Just then, the distant wail of sirens and the sound of an explosion echoed through the air. Jiro's super hearing picked up every detail—there was a bank robbery in progress, and the cops were already exchanging fire with the robbers.

"New York never rests. Perfect time to test out my powers," Jiro said, walking toward the floor-to-ceiling window. "Wanna come, Tony?"

"Hold on. You need to suit up first," Tony said, a spark of excitement in his voice."Unless you wanna keep saving the world dressed like that?"

Jiro suddenly realized—he still didn't have a proper superhero outfit.

Three seconds later, Jiro landed back in Stark's lab.

The thing that immediately caught his eye was the black suit displayed in the center of the room.

Matte black finish. Gold lines flowing like molten lava. The design was sleek and powerful.

"Like it?" Tony spread his arms. "Special edition: Dark Guardian. Won't interfere with your powers, but makes you look..."

He paused for effect. "More professional."

Jiro stepped closer and touched the armor with one finger.

The suit responded instantly, assembling itself over his body.

It fit perfectly, molding to every muscle. It felt almost weightless.

Jiro stood in front of the window, looking at his reflection.

The black made his tall frame look even more imposing. The golden lines shimmered faintly under the light. The lack of a faceplate exposed his entire face—but that only added to the dangerous edge.

"Why black?" he asked.

Tony shrugged. "First, you're clearly not the red-cape Boy Scout type. Second, I've noticed you like black. Third..."

He gave a sly grin. "It suits your whole vibe—powerful, mysterious, unstoppable."

Tony glanced at his own armor. "I still prefer going out fully suited up. You go on ahead. I'll catch up."

Jiro nodded, then jumped.

He passed straight through the glass window, soaring into the night sky.

The glass rippled like water as he moved through it—no cracks, no shards, no sound.

Tony watched him disappear into the sky and muttered to JARVIS, "Start recording: energy levels, flight mode, biofield behavior—I want all the data."

"Already done, sir," JARVIS replied. "However, I must inform you—based on current data, the success rate of any defense against Mr. Jiro is less than 0.0001%."

Tony grinned with determination. "Then let's move that decimal a few places to the right."

Outside the Third Bank of Queens, chaos had already broken out.

Peter Parker frowned slightly. His homemade Spidey suit was torn in several places.

The monster in front of him had swollen to three meters tall. Its muscles had burst through its skin, exposing blood-red fibers.

"Dude, you seriously need to chill," Peter muttered, shooting a web that stuck to the thing's eyes.

"We can talk this out."

The mutant roared, yanked off the webbing, and threw a punch at Peter.

Peter dodged fast, and the concrete wall behind him came crashing down under the impact.

"Okay, I guess negotiations are off," Peter said as he backed up quickly, checking his suit.

"This suit's only three days old, man. You better pay for that."

The mutant grabbed a steel beam and was just about to hurl it at Peter when—

A black figure dropped from the sky, and the steel beam was reduced to dust mid-air.

As the dust settled, a tall figure floated above the ground, his black armor gleaming coldly under the sunlight.

"Step back, kid," said Jiro, his voice deep and powerful.

Peter's eyes went wide. "Whoa! A new guy? I'm Spider-Man, and you are…"

"Save the chat for later," Jiro cut him off, locking eyes on the mutant.

"Tony, get the kid somewhere safe."

"Alright, Dark Knight," Tony replied as he landed next to Peter.

"Come on, pajama boy, time for the pros to take over."

Before Peter could react, Iron Man grabbed him and flew them over to a nearby rooftop.

"Wait! That guy injected some kind of serum—his strength is still growing!" Peter struggled. "I can help!"

Tony set him down. "Just watch, kid. Today you get to witness real power."

Down below, the mutant sensed the threat. His muscles swelled even more.

He picked up a police car and hurled it straight at Jiro with all his strength.

Jiro didn't move. Right before the car smashed into him, he calmly blew out a breath.

Whoosh!

The police car instantly froze into a solid block of ice—then shattered into a thousand glittering shards.

The mutant froze, instinctively stepping back.

"It's over," Jiro said. His voice wasn't loud, but it echoed through the whole block.

In the blink of an eye, he appeared right in front of the mutant. He moved so fast, even Peter's enhanced vision only caught a blurry shadow.

With one clean strike, he chopped the mutant's neck with the side of his hand.

Crack!

The sound of bones snapping rang out. The mutant's eyes rolled back, and he collapsed with a heavy thud.

The whole fight lasted less than three seconds.

"Th-that's it?" Peter's jaw dropped.

"I was going toe-to-toe with him for fifteen minutes!"

Tony patted Peter on the shoulder. "Welcome to the world of top-tier power, kid."

Jiro knelt to examine the unconscious mutant. "This wasn't natural mutation. I see signs of organized experiments."

The sound of sirens drew closer. Peter suddenly got nervous. "Uh—I should go. I've still gotta pick someone up."

"Wait, Spider-Man," Jiro called out to him. "You were brave out there."

Peter froze. "Really? I mean… thanks! Uh… what should I call you?"

"Jiro," he replied, his black armor gleaming softly in the sunlight. "You can call me Jiro."

"That is so cool!" Peter jumped in excitement. "Are your powers from the armor? Or is it—uh, I mean…"

Tony rolled his eyes. "Give it a rest, kid. Now scram—cops are coming."

Just before swinging away, Peter shouted, "Mr. Jiro! Your armor is awesome!"

Jiro watched the red-and-blue figure disappear between the buildings, a faint smile tugging at his lips. "Interesting kid."

"A vigilante in pajamas," Tony muttered, though there was a glimmer of respect in his eyes.

"He's got potential though. So… how's the suit feel?"

Jiro glanced down. The black armor looked sleek but intimidating in the sunlight, perfectly matching his vibe.

"Feels great," he said simply. Then, with a burst, he soared into the sky. "I'm gonna do a quick patrol."

Tony watched the black figure vanish into the distance and mumbled, "Guess I'd better stock up on spare materials. This guy makes anything look cool."

"....."
