The descent back to Earth wasn't the graceful victory lap a hero might expect. Leo guided Tony's dead weight down toward the jagged remains of the Stark Tower penthouse, the metallic scraping of the Mark VII against the marble floors sounding like a dying groan.
Tony didn't move for a long moment. He just lay there, staring at the ceiling he'd spent millions of dollars to design, now featuring a panoramic view of a smoking Manhattan.
The silence didn't last. The Hulk came thundering up from a nearby skyscraper, his massive green feet cracking the pavement of the terrace as he landed with a roar that was more "get out of my way" than "we did it." Shortly after, Thor touched down, his cape tattered but his presence as regal as ever, carrying a very soot-covered Steve Rogers. The Captain didn't exactly stick the landing; he tumbled, rolling awkwardly across the debris before pushing himself up with a wince.
Clint Barton, the man who had spent the last hour playing god from the rooftops, finally made his way back. On the way, he'd actually stopped to scavenge a few of his specialty arrows from the corpses of alien soldiers, sliding them back into his quiver with a clinical efficiency.
Natasha was already there, standing by the console. She had set the scepter down—the very thing that had nearly ended the world—and was watching Leo and Tony with a look of profound relief she'd never admit to having. Dr. Erik Selvig was slumped in the corner, looking every bit the exhausted old man he was, his eyes glassy as he waited for whatever judgment or rescue came next.
The team was finally together. No more comms, no more static. Just seven people standing in the ruins of a billionaire's dream.
The Mark VII stood tall one last time, though it looked like it had been through a car compactor. Steve, covered in the grey dust of crumbled buildings, looked out over the horizon and let out a breath that sounded like a prayer.
"I think we actually pulled it off," he muttered, the weight of the shield finally feeling heavy on his arm.
Tony's helmet hissed as it detached. He set it aside, his face pale and glistening with sweat. The terror of the void was still dancing behind his pupils, but he forced a jagged grin.
"Great job, team. Seriously. A-plus effort all around," Tony rasped, his voice cracking. He looked at the ragtag group—the god, the assassin, the soldier, the monster, and the kid. For a man who didn't play well with others, he felt a strange, uncomfortable warmth in his chest. "I say we call it. No work tomorrow. In fact, let's just close the office for the week."
He turned his head toward Thor, his neck stiff. "You ever try Arabic kebab? Shawarma? There's a place a few blocks over. I have no idea if the roof is still on the building, but I've got a craving that won't quit."
Steve actually chuckled, leaning against a pillar. "I know a hole-in-the-wall Chinese spot in Queens that's probably still standing. I'm buying, if anyone's interested."
Leo stood in the center of the chaos, his golden wings folding back into his spine like liquid light. He tapped the side of his temple, the nanotech faceplate receding to show a tired but genuine smile. "I'm in for whatever doesn't involve alien tech."
Thor didn't join the laughter. He shifted his weight, his eyes drifting toward the interior of the penthouse. "We still have one piece of business left."
The mood shifted instantly. Tony's brow furrowed. "Right. The kebab can wait twenty minutes."
They walked into the living area. It was a disaster zone—human-shaped craters in the floor, shattered glass everywhere. Loki was there, curled on the steps, looking like a broken doll. He groaned, one hand clutching a step as he tried to drag his bruised body upward. He felt the light in the room dim, a collective shadow falling over him.
He looked up.
Seven figures stood in a semi-circle of pure intimidation. Clint was at the front, an arrow notched and aimed squarely at the space between Loki's eyes, his finger twitching with the memory of being a puppet. Tony stood to the left, suit-less but defiant, shoulder-to-shoulder with Steve. Behind them, the Hulk loomed like a green mountain, his breath coming in hot, angry huffs. Thor stood with Mjolnir gripped tight, his expression one of brotherly disappointment that cut deeper than any blade. Natasha stood near the scepter, her eyes cold enough to freeze the blood in Loki's veins.
And then there was Leo. He hovered slightly off the ground behind Clint, a faint golden aura shimmering around him. Two wicked-looking metal spikes floated at his sides, quivering with kinetic potential.
Loki looked at them, then back at the floor. He pushed himself up into a sitting position. Most of his physical wounds had closed—Asgardian healing was no joke—but the stains of the battle remained.
"If it's all the same to you," Loki said, his voice a dry rasp as he looked at the Avengers, "I believe I'll take that drink now."
Leo didn't say a word. He flicked a finger. The two metal spikes snapped forward, wrapping around Loki's wrists and fusing into a pair of solid, vibration-resistant cuffs in a spark of gold. At the same time, Leo pulled his glasses off his face and tossed them into the air. They didn't fall; they hovered behind Loki, a tiny red light blinking.
Click.
"O-Unit 2 just took the shot," Leo said, glancing at the team who looked at him with confusion. "You guys want a copy? I'll email it to you. It'll make a great Christmas card."
The city didn't stay quiet for long.
Within the hour, Manhattan was swarming. S.H.I.E.L.D. tactical teams, NSA analysts, NYPD, and CIA operatives flooded the streets. They weren't just there to help; they were there to scavenge. Fury's Helicarrier moved into a low hover over the Hudson, acting as a giant vacuum for every scrap of Chitauri data they could find.
This wasn't just a battle; it was the start of a new era. Laws would be rewritten. New industries would sprout from the wreckage of alien engines. Clandestine groups would form in the shadows, all hunting for a piece of the "New World."
Leo spent the next few hours doing the heavy lifting. Following Fury's direct orders, he used his magnetic control to haul the massive, stinking corpses of the Leviathans out of the residential streets and into the outskirts where S.H.I.E.L.D. could dissect them in peace.
When he finally flew back to the Tower, the sun was beginning to set, casting long, bloody shadows over the ruins.
Tony had already started the work. He had stripped out of the Mark VII and was now dressed in a simple, oil-stained sweater with the sleeves rolled up. He was hunched over the Tesseract rig, his hands trembling slightly as he worked the controls to dismantle the containment field. He looked fragile, like a man held together by sheer willpower.
Steve, Natasha, and Clint had already left to debrief with Fury. Thor remained, a silent sentinel standing over Loki, who was gagged and bound, looking thoroughly bored with his captivity.
Leo landed softly and walked over to Tony. He could see the micro-tremors in the billionaire's hands. Without a word, Leo stepped up behind him and placed both hands on Tony's shoulders.
A wave of brilliant gold energy flowed from Leo's palms. Tony stiffened for a second, then slumped, a long sigh of relief escaping his lips.
"Leo... tell me you've talked to Jenny and the others," Tony said, his voice muffled. "I'm pretty sure if you haven't seen them yet, I'm the one who's going to get the bill for the emotional trauma."
The light raced through Tony's system, mending micro-tears in his muscles, soothing the bruised tissue of his lungs, and calming his racing heart.
"They've probably been watching the news," Leo replied with a grin. He had missed Jenny and George more than he wanted to admit. The constant fighting made him crave the normalcy of their living room. "I'll go pick them up in a bit. They're going to chew my ear off."
"Good. My jet is sitting in LA," Tony said, his eyes half-closed as the warmth spread through him like a stiff drink. "Take it. Fly them back here. Assuming your house hasn't been looted by people looking for alien souvenirs."
Leo chuckled, but then his expression turned serious. He twitched a finger.
Deep inside Tony's chest, near the glowing rim of the arc reactor, half a dozen tiny, jagged metal shards began to vibrate. They were the shrapnel from the Ten Rings' bomb—the things that had defined Tony's life for years. Tony felt a strange, cool sensation brush against his heart.
The gold light sealed the exit wounds before they even opened. The shards flew out, hovering in the air before melting together into a single, hollow golden bullet that dropped into Leo's palm.
"Problem solved," Leo said, holding up the metal. "So, when are you going to ditch that battery in your chest?"
Tony tapped the arc reactor, a thoughtful look on his face. "No rush. I still have a pretty long to-do list, and this thing is a great nightlight."
The golden glow faded back into Leo's skin. Tony stood up, stretching his back. He felt twenty years younger. He turned back to the rig and finished the final sequence.
The machinery hissed, and the containment arms retracted.
"Thor, what's the plan?" Leo asked, turning to the Asgardian.
Thor glanced down at Loki. "I take him to Asgard. He must face the All-Father's judgment for what he has done here."
"But the Bifrost is gone, right?" Leo asked, tilting his head. "Can Heimdall just reach down and grab you?"
"No," Thor admitted, looking at the glowing blue cube. "But the Tesseract is more than just a power source. It is a key. I will build a rig to harness its spatial energy and send us across the branches."
"How does that even work?" Leo was genuinely curious.
Thor leaned on his hammer. "The Tesseract holds the raw energy of space itself. With an Asgardian beacon and a lock on the World Tree—the Yggdrasil—we can bridge the gap."
Loki watched Leo from the floor, his eyes narrowed. He had fought gods, frost giants, and sorcerers, but he still couldn't figure out what Leo was. The boy was an anomaly, a variable that shouldn't exist.
Leo nodded, processing the theory. A Tesseract-powered beacon... locking onto the Yggdrasil's trunk... following the dimensions like branches. It sounded simple in theory, but he knew that across the Nine Realms, almost nobody had the power to actually touch the World Tree that linked existence together.
Within minutes, Tony had the core fully exposed.
The Tesseract lay on the pedestal, pulsing with a rhythmic, azure light. It was beautiful—a perfect cube of infinite depth. For the first time, Leo stood within arm's reach of it.
He could feel it. It wasn't just a battery. It was a presence. It was one of the six.
The Space Stone.
The energy roiling inside was vast and ancient. It looked like a piece of the sky had been trapped in glass. It felt pure, almost harmless, but Leo could sense the pressure it exerted on the fabric of reality around it.
Driven by a curiosity he couldn't suppress, Leo reached out his hand toward the glow.
