GhostShield Chapter 3.

Chapter 3: GhostShield of Santiago.

-

The very next day, Alexei was gone before SHIELD even finished their internal memo.

One clean exit. No trace. No farewell.

He locked down the Greenland bunker, wiped every surveillance node, rerouted tracking systems, stole a shield vehicle by hacking it's systems and vanished into a world that he already considered beyond saving.

Two weeks later, he was in New Mexico, hiding in an abandoned SHIELD fallback site. The walls were scorched. The power unreliable. He didn’t care.

He worked with what he had—canned rations, a bundle of emergency cash from his mother's safe, his father's survival gear and burner laptops.

He slept in shifts and read field manuals in the dark. Movement drills in the mornings. System audits at night. He didn’t speak. Didn’t think about Steve or Natasha.

Not out loud.

Frank Castle found him on day sixteen.

No knock. Just a door kicked in and a figure in black, weapon raised.

Alexei didn’t reach for anything. He already knew the voice before it spoke.

“You’re taller than I thought.” Frank said, lowering his rifle.

He looked older—grayer, rougher, not that he was ever clean to begin with. His eyes scanned the room, the setup, the stacks of gear. He said nothing for a while.

Then: “You look like him. But the eyes? That’s your mother.”

Alexei sat still.

Frank tossed a duffel bag onto the floor. It hit with a thud—gear, food, tech. A Stark field suppressor on top.

“Eat. Then you train.”

That was it. No comfort. No condolences. Not even an explanation as to how and why the Punisher had tracked him down. Just orders.

But Alexei followed them. He knee he was going to need it.

They didn’t talk about the mission. Or the deaths. Or why no one came for him but Frank. And when he asked about the nature of Castle's relationship with his parents, all he got was a grunt and 50 more pushups stacked onto his 5th set.

That was the other thing- Frank trained him the only way he knew how. Full contact. No warnings. No soft landings.

He taught Alexei how to gut a hard drive while running. How to turn a pressure cooker into a blast trap. How to vanish in under thirty seconds with two tools and no backup.

Alexei never asked for reasons. He just did it.

Frank gave him the nickname “Kid Cap” sometime during their second week together. A grunt between drills. Meant as a jab.

“You’re him. Just broken.”

Alexei didn’t mind. He kept the name.

By the third month, he was fluent in small-unit tactics. He could scramble most drones before they could scan him. He could disarm a man twice his size before the second heartbeat.

He didn’t smile. He didn’t speak much. He just kept moving.

Frank didn’t say it, but he noticed. The way Alexei worked, the way he planned—he wasn’t just training to fight.

He was training for a war.

By the time Alexei turned fourteen, he was operating solo.

Frank had taught him everything he could, and Alexei had taken it further.

His intelligence grew as his wealth of knowledge expanded. Natasha had taught him the value of both in spycraft- a gray area Steve had issues with.

With his IQ he modified old Stark drones bought off the black market into recon scouts. Hacked retired SHIELD comms to intercept encrypted chatter- data information he would sell to interested parties while collecting dirt on Shield. Built an EMP net out of repurposed Hydra scrap and smuggled Wakandan Tech.

He didn’t wear a costume as he was no hero. His was a vendetta. Unlike the lying Fury, he wouldn't call it justice.

That said, he wore an armor for protection whenever he was out on his tasks or accompanying Castle on his raids.

Not too fancy but nothing to scoff at either. The titanium kevlar mesh was dark and minimal— with just enough plating to block small arms, reinforced at the core. He carried no official weapon but had been training to master the shield. The one he’d built himself was light, absorbent, and silent. No colors. No star.

Just a symbol etched into the center—barely visible unless the light caught it right. A shield, fractured down the middle.

On police scanners, they called him a rogue. A tech-wielding vandal. A vigilante hitting local cartels, private arms dealers. Always precise. Always gone before the cleanup.

Online, a codename started spreading.

The Ghostshield of Santiago.

Santiago being the Mexican city he'd been holed up for the last two years, training under the Punisher.

Alexei never claimed the name, but he didn’t reject it either.

Frank even warned him. “The second they start naming you, they start hunting you.”

Alexei nodded. But he kept moving.

The world had become a map of silences—black sites, ghost cities, shadow arms deals. He knew where the bodies were buried, because he’d read the files no one else could see.

He wasn’t trying to fix the system. He was carving out the rot.

But Frank saw something else happening.

It started slow. Paranoia. Frank had always been careful, but now it edged into obsession. He scanned for drones every hour. Changed safehouses weekly. Ranted about SHIELD sleeper programs, about Fury running ghost wars through kids too broken to push back.

At first, Alexei ignored it. Fury was already dead to him.

But the more he listened, the more it made sense.

Steve had been silenced. Natasha erased. SHIELD didn’t protect people—it managed outcomes. The Avengers picked the fights they could win. And the rest of the world?

Collateral.

By now, Alexei had pieced together parts of the Black Vault. What had happened after Sudan. How close SHIELD had come to wiping an entire village just to cover it up. How the final report was edited to remove names.

Even in death, his parents had been redacted.

So he stopped believing in legacies. Heroes. Institutions.

He stopped waiting for someone to hand him purpose.

Frank called it survival. Alexei called it clarity.

They weren’t fighting evil. They were preparing for the inevitable.

You either die a hero, or you live long enough to see yourself become the villain.

In fighting to save the world...SHIELD had become the very thing they sought to prevent.
