Everyone was genuinely interested in this question. From earlier rounds, it was already clear that the idea of time travel came from Scott Lang.
But let's be honest—Scott Lang inventing a time machine? That's like asking a raccoon to build a spaceship. Creative thought, zero execution.
In the previous footage, after Scott proposed time travel to Captain America and Black Widow, he immediately asked who they should even talk to about something this insane. And when he tried to explain the theory, it was painfully obvious: he had no way to locate time within the Quantum Realm.
In short, everything Scott proposed was just a "crazy idea."
He himself absolutely could not make it happen.
This question, therefore, was meant to reveal who actually invented the time machine—or at least made the decisive contribution.
Evaluating the Candidates
"Stark, Banner, Hank Pym—every one of them is a world-class scientist," Captain America said after scanning the four options.
Tony Stark and Bruce Banner were well-known to everyone present. Their capabilities were no mystery.
As for Hank Pym, although few had met him in person, he had appeared repeatedly in the quiz footage. He was the inventor of the Ant-Man suit and someone who could literally command ants—clearly a top-tier genius.
After all, in the United States, if you don't have real skills, you don't get to casually look down on Tony Stark.
And Shuri?
"We don't know much about her," Steve continued, "but T'Challa once said that many of Wakanda's advanced technologies were designed by her. She should also be an exceptional scientist."
"True," Scott Lang nodded. "We don't fully understand Wakandan tech, but the nanotech suits were absolutely built by Shuri. Nanotechnology isn't something just anyone can pull off."
At this point, all four candidates were confirmed geniuses. No weak links here.
So the real question became: who was most likely to contribute to time travel?
Field of Expertise Matters
"Time machines rely on quantum physics, right?" Thor asked, carefully pronouncing the term like it might explode.
"Yes," Steve replied.
"Then which of these people actually studies quantum physics?"
Steve thought for a moment."Stark and Banner aren't currently focused on that field. Shuri—we're not sure. But Hank Pym? According to everything we know, he definitely studies quantum physics."
This wasn't speculation. After the Avengers' internal conflict, Hank Pym had already built a tunnel into the Quantum Realm.
That kind of device doesn't come from dabbling—it comes from decades of deep research.
"Hank Pym is absolutely a quantum physics expert," Tony Stark confirmed.
The Ant-Man suit itself relied on quantum mechanics. And years earlier, Pym's wife Janet had been trapped in the Quantum Realm, which directly motivated his research.
Even Scott's time-travel idea only emerged after he spent five hours inside the Quantum Realm.
And who built the machine that allowed entry into the Quantum Realm in the first place?
Hank Pym. No debate.
The Problem with Hank Pym
"So logically, Hank Pym seems the most likely," Peter Parker said. "But if that's the case, why didn't Scott go to Hank Pym first instead of Captain America?"
That question hit dead center.
Scott Lang and Hank Pym weren't just acquaintances.They were partners. Mentor and successor. They'd fought enemies together and even rescued Janet from the Quantum Realm.
With that kind of relationship—and Hank Pym being a quantum expert—Scott going to Captain America first made no sense.
Especially since Scott and Steve weren't even that close at the time. Scott had to reintroduce himself when he showed up.
So why skip Hank Pym?
"That's exactly the issue," Doctor Strange said weakly from his hospital bed. "Something doesn't add up."
Thor thought for a moment."Maybe Scott did go to Hank Pym, but Hank couldn't help, so Scott went to Captain America afterward?"
"Possible," Tony Stark said, "but I think there's a more likely explanation."
Tony paused, then said it bluntly:
"Hank Pym is dead."
The Missing Scientist
"Dead?" Peter blurted out.
"Yes," Tony said firmly."When Thanos snapped his fingers, Scott was stuck in the Quantum Realm. Hope was supposed to pull him out—but she turned to dust."
"And Hank Pym?" Tony continued. "What if he was there too?"
Entering the Quantum Realm isn't a one-man job. Someone has to operate the controls. Hope wasn't necessarily the only one present.
"If Hank Pym was there," Tony said, "he could've been dusted as well."
Thor frowned."That's still speculation. We only know Hope died."
Scott Lang suddenly spoke up.
"No—Tony's right."
Everyone looked at him.
"Where did I come back?" Scott said. "A junkyard."
"If Hank were alive, would he let that quantum van rust in a trash heap? If he were alive, would he leave me stuck for five years?"
Captain America nodded gravely."Hank Pym must be dead. Whether from the snap or earlier, he wasn't around anymore."
No one argued. The logic was airtight.
Narrowing It Down
"Fine," Thor said. "So Hank Pym is out—the only confirmed quantum physicist."
"That leaves us three," Doctor Strange said. "And maybe relationships are the key."
Scott had gone to Captain America and Natasha. Naturally, they'd turn to people they trusted.
"Shuri's unlikely," Thor said immediately. "Wakanda is extremely closed off."
Still, Steve played it safe."We've worked with Wakanda in the future. Let's keep her as 'low probability,' not zero."
That left two names:
Tony StarkBruce Banner
Both were brilliant. Both were close to the Avengers. Either choice made sense.
Which meant… total stalemate.
At this point, everyone agreed on one thing:
The answer had to be either Tony Stark or Bruce Banner.
Shuri was already trailing far behind.
Final Decision
"If only one person could pull off something as insane as time-space positioning," Peter Parker finally said, "it has to be Mr. Stark."
Tony immediately stopped him.
"Nope. I'll answer myself."
If the answer was wrong, better to sink your own ship than drag a kid down with you.
"I choose—Tony Stark."
[Correct Answer!]
The system's confirmation appeared instantly.
And just like that, the truth was sealed.
Only Iron Man could solve time travel.
