In the humid, bustling heat of Calcutta, Dr. Bruce Banner was finding that anonymity didn't necessarily mean peace. For the past week, a localized viral fever had been tearing through the slums, and Bruce had spent every waking hour administering IV drips and cleaning infections.
He was at the communal well, scrubbing the grime of the day from his hands, when a young girl tugged on his sleeve. She looked no older than seven, her eyes wide with a practiced terror. She told him her father was unconscious in their home on the edge of the town and begged for the "Good Doctor" to follow her.
Bruce hesitated. His internal "Hulk-dar" was buzzing, but the humanitarian in him won out. He followed her through a labyrinth of narrow alleys until the sounds of the market faded into an eerie silence. They reached a secluded, derelict house. The girl pointed inside and then, with a speed that wasn't exactly civilian, slipped through a small opening in the wall and vanished.
Bruce sighed, looking around the empty room. "I really should have asked for the fee upfront," he muttered to himself.
"For a man who supposedly wants to avoid the spotlight, you've picked a remarkably loud place to hide, Doctor."
The voice was cool, precise, and distinctly western. Natasha Romanoff stepped out from behind a hanging tapestry, her red hair tied back, dressed in local traditional silks that helped her blend into the shadows.
"Constant avoidance isn't exactly a long-term strategy, is it?" she added.
Bruce looked at her, a weary, indifferent smile playing on his lips. Months of mental training with Leander's gift had made him a master of his own pulse. He didn't feel the familiar heat in his neck. Not yet.
"What's the alternative? More yoga? Hot tea?" Bruce asked, leaning against a wooden pillar. "Luring me to a remote shack was smart. I'm guessing the perimeter is already crawling with your friends."
"It's just you and me," Natasha said, taking a seat at a rickety table.
"Was the little girl a junior agent? She's got a bright future in the industry."
"We start them young. I did too."
"Who are you?"
"Natasha Romanoff."
Bruce nodded, his eyes scanning her for hidden weapons. "Are you here to kill me, Natasha? Because to be honest, I'm starting to think the person who can actually kill me hasn't been born yet. Many have tried. They usually just end up as a smudge on the pavement."
"No, I'm not here for a fight," Natasha said, her voice softening. "I'm here on behalf of S.H.I.E.L.D. Director Fury needs your help."
"S.H.I.E.L.D.? How did you even find this place?" Bruce's mind immediately went to Leander. Had the kid sold him out? No, Leander didn't seem like the type to hand a friend over to a government agency.
Natasha leaned forward. "We've been keeping a peripheral eye on you for a year, Doctor. We've actually spent a considerable amount of resources making sure General Ross's scouts went the wrong way. Director Fury seems to think you're worth the effort. Someone high up once vouched for you, and you've stayed green-free for a year. We'd like to keep it that way."
"It's not a streak I can guarantee," Bruce said, his voice dropping an octave.
Natasha pulled out a smartphone and slid it across the table. On the screen was a high-resolution image of the Tesseract. "We're looking at a global extinction event, Bruce. This is the Tesseract. It's a literal door to the stars, and someone just walked through it and stole it."
Bruce reached into his pocket for his glasses. As he pulled them out, a small, heavy object tumbled out with them—the dual-metal model Leander had fashioned for him. It gleamed with a strange, internal light even in the dim shack.
"What does Fury want me to do? Eat it?" Bruce asked, squinting at the image of the cube.
"The Tesseract emits a low-level gamma signature," Natasha explained. "It's too faint for our satellites to lock onto, but it's there. Nobody on the planet knows gamma better than you. Fury doesn't want the monster; he wants the scientist."
"So you're not here to put the 'monster' in a cage?"
Natasha leaned back, her expression unreadable. "At least, he didn't tell me that."
"Stop lying to me!!" Bruce suddenly slammed his fist onto the table, his body lunging forward. The force of the blow made the little metal figurine roll across the floor.
In a heartbeat, Natasha's training took over. She drew a Glock from a concealed holster beneath the table, her hands locked in a perfect firing stance. Her grip was steady, but her eyes—usually cold and calculating—welled with a genuine, primal fear. She knew that if she pulled that trigger, the building would cease to exist.
"I'm sorry," Bruce said, his voice instantly returning to a calm, almost mocking whisper. "I just wanted to see your reaction. I wanted to see if the 'no cage' promise was real."
He looked at the gun. "We should probably de-escalate, Natasha. Put the gun away, and I promise the 'Other Guy' won't come out to play."
Natasha's breath hitched. She slowly holstered the weapon and tapped her earpiece. "Stand down. All teams, clear the area. He's with us."
Bruce gave a soft, dry laugh. "Just you and me, right?"
Natasha didn't answer immediately. Her gaze was fixed on the floor where the metal model had come to rest. She walked over, picked it up, and felt the incredible density of the alloy. It was a masterpiece of metallurgy.
"Doctor... where did you get this?" she asked, her voice trembling slightly. "I've seen this style before. The way the metals are fused... it's not human tech."
"A friend gave it to me," Bruce said, taking it back. "A very talented one. Why? Where did you see it?"
"I was undercover at Stark Industries. I saw an arc reactor model on Pepper Potts' desk that had the same signature. But the person who made it... he's just a kid. A teenager named Leander Hayes."
Bruce's brow furrowed. "You know Leander?"
Natasha froze. "You know him too? There's nothing in the S.H.I.E.L.D. files connecting a fugitive scientist in India to a high-school kid in Queens. How is that possible?"
"I thought he was one of yours," Bruce muttered, his confusion deepening. "He found me months ago. He helped me... talk to the monster. If he isn't S.H.I.E.L.D., then who the hell is he?"
New York City. Manhattan.
While Natasha was uncovering a massive hole in S.H.I.E.L.D.'s intelligence, Tony Stark was busy making a statement.
High above the Atlantic, the Mark VI suit banked sharply, trailing a massive power cable toward the ocean floor. Tony had spent the last week bypassing the city's power grid, connecting his private arc reactor directly to the newly finished Stark Tower.
"Jarvis, give me the green light," Tony said, his voice echoing in the helmet.
"Power levels at 100%, Sir. The grid is stable."
The next moment, the skyline of Manhattan changed forever. Massive, glowing letters—S-T-A-R-K—ignited atop the tallest spire in the city, fueled by clean, sustainable energy.
Tony let out a celebratory "Woo!" and accelerated, breaking the sound barrier as he streaked toward the landing platform. He touched down with a metallic thud and walked toward his penthouse.
As he crossed the threshold, a ring of autonomous mechanical arms rose from the floor. They moved with surgical precision, unbolting the Mark VI's plates and storing them in the floor's concealed lockers as he walked. By the time he reached the bar, he was in a three-piece suit, looking like he'd just stepped out of a boardroom rather than a flight from the ocean floor.
He poured himself a drink, looking out at the city he now powered. But his eyes drifted to the empty space where a certain teenager usually sat.
"Jarvis, any word from Leander?"
"Still no signal, Sir. However, Director Fury is currently in the elevator. He appears to be in a very bad mood."
Tony sighed, taking a sip of his scotch. "Well, tell him to come in. I've been waiting for a reason to tell him 'I told you so' about that blue cube."
