The sky above New York was silent, save for the hum of the Arc Reactor and the whistling wind.
Two figures floated there, locked in a stare-down that defied physics and logic.
Inside the Iron Man Helmet:
"Yes, Sir," Jarvis confirmed. "It is Lucas Chen."
"He... he can fly?" Tony Stark stammered. "Since when? How? Is he a mutant? An Inhuman? A wizard?"
Tony felt like the smartest kid in class who had just realized he was studying the wrong textbook. He had spent weeks analyzing Lucas's diary, building a psychological profile of a "Civilian Transmigrator."
Result: Harmless. Greedy. Lazy.
Reality: Floating at 30,000 feet without a suit.
"Jarvis," Tony said, his voice dropping an octave. "Update the threat assessment. Lucas isn't a civilian. He's a Super."
"Assessment updated, Sir. Threat level raised from 'Low' to 'Unknown.' Note: His flight mechanism produces no exhaust, no heat signature, and no sound. It is bio-gravitational."
"Bio-gravitational," Tony muttered. "Great. He's Superman."
Tony thought back to the Arc Reactor in his chest. The Mini-Fusion Plant. He had built it because of Lucas. He had skipped the cave because of Lucas. He had bought stocks in his own company because of Lucas.
"He knew I would pivot to Clean Energy," Tony realized. "He was waiting for the stock dip. But... if he can do this, why does he care about money?"
"Perhaps," Jarvis suggested, "flight does not pay the rent."
"Fair point."
Outside the Helmet:
Lucas Chen was having a similar meltdown.
"What is this timeline?" Lucas thought, panic spiraling.
"In the comics, Tony becomes Iron Man during the Vietnam War. In the MCU, it's Afghanistan. But here? He just... skipped the trauma?"
"No kidnapping. No Yinsen. No cave. He just built the Mark 2 in his garage?"
"Is the TVA asleep?" Lucas looked around nervously, half-expecting an orange portal to open and a Minuteman to prune them both. "If He Who Remains is dead... then the timelines are branching. Is this a branch?"
"If this is a branch," Lucas realized with a sinking feeling, "then my stock portfolio is worthless. If Stark industries never crashes... I never get rich."
"My dip!" Lucas mentally screamed. "My beautiful, beautiful dip!"
He looked at the red-and-gold armor. It was pristine. No scratches. No battle damage.
"Tony Stark?" Lucas called out, his voice carrying easily in the thin air.
The Confrontation:
Tony's faceplate didn't retract. He decided to play it cool. He couldn't let Lucas know about the diary. The headache protocol was dormant as long as he didn't mention the book directly.
"You know me?" Tony's voice came through the external speakers, filtered and metallic. "I guess the paint job gives it away."
"Yeah, hard to miss," Lucas replied, crossing his arms and hovering casually. "Hot Rod Red. A bit flashy for a test flight, isn't it?"
"I like to be seen," Tony quipped. "And you? I don't recall seeing 'Flying Man' on the news. Are you a new hero? Or just a very advanced weather balloon?"
Lucas laughed. It was a nervous laugh.
"Just a guy catching some rays," Lucas said. "The UV index down there is terrible."
"Right. Sunbathing at 30,000 feet. Standard behavior."
Tony maneuvered closer, his thrusters flaring.
"So," Tony said, his tone casual but his sensors scanning every inch of Lucas's body. "You seem to know a lot about flashy paint jobs. And you seem surprised to see me."
"I am," Lucas admitted. "I thought... I thought you were in Afghanistan."
Tony froze inside the suit.
"Afghanistan?" Tony asked. "Why would I be in Afghanistan?"
"Business trip?" Lucas shrugged. "Weapons demo? The Jericho Missile?"
"I cancelled that trip," Tony lied smoothly. "Decided to stay home and work on my tan. Like you."
Lucas narrowed his eyes behind his glasses (which he had hastily put back on).
"Cancelled it?"
"Something came up," Tony said. "A feeling. Call it intuition."
Call it a diary spoiler, Tony thought.
"Well," Lucas said, trying to salvage the conversation. "Good for you. Afghanistan is lovely this time of year, but the hospitality can be... explosive."
"Is that a threat?" Tony asked, his repulsors humming slightly louder.
"No!" Lucas raised his hands. "Just... a figure of speech. You know. War zones."
"Right."
The silence stretched again.
"So," Tony broke the tension. "You have a name? Or do I just call you 'Sunboy'?"
"Call me Superman," Lucas said, testing the name on the man who would be Iron Man.
"Superman," Tony repeated. "Bit derivative, isn't it? DC Comics might sue."
"In this universe?" Lucas smirked. "I think I'm safe."
"Fair enough," Tony nodded. "Well, Superman. I'm Iron Man."
"I know," Lucas said. "The name fits."
"It does, doesn't it?" Tony preened. "Gold titanium alloy. Solves the icing problem."
"Icing problem?" Lucas blinked. "You fixed that already?"
"I'm a fast learner," Tony said.
Because you wrote about it in your diary, you idiot, Tony thought.
"Well," Tony engaged his thrusters. "Nice meeting you, Superman. Try not to hit any planes."
"You too, Iron Man."
Tony blasted off, a sonic boom trailing in his wake.
Lucas watched him go, his mind reeling.
"He fixed the icing problem," Lucas whispered. "He cancelled the Afghanistan trip."
"He knows," Lucas realized. "He knows something. Or... someone told him."
"Did I... did I butterfly effect the entire MCU just by existing?"
Lucas looked at his hands.
"If Tony never goes to the cave... he never meets Yinsen. He never learns humility. He never stops making weapons."
"Oh god," Lucas paled. "I might have just created a timeline where Tony Stark is still a Merchant of Death... but with an Iron Man suit."
"Superior Iron Man?"
"This," Lucas groaned, "is going to be a problem."
