Superman in Marvel: Multiverse Ascendant

"Right now, we can't find a tool that can fully withstand your full-strength punch!"

"We'll have to try another method—using multi-dimensional data to estimate the approximate value." Tony always had flexible solutions.

"What do you want me to do?" Leon asked.

"Exerting force in the air shouldn't affect your condition, right?"

"No, I have a biological force field."

Tony adjusted all the instruments and spoke through the radio.

"Then fly up and push the tester down—like Superman pushing an asteroid."

"It won't measure your punching strength, but it will test your pushing strength."

"We'll check your punching speed later, and Jarvis will combine the data to estimate your full punching power."

"Okay."

Leon took off, flipped midair, and placed his hands on the iron block.

"I'm going to start exerting my strength!"

"Use your greatest strength!"

"Of course!"

Leon focused, his muscles tensed, and he pushed downward with all his might.

Tony reacted instantly.

The numbers on the screen shot up to nine digits almost immediately, startling him.

The data continued rising rapidly until Leon roared in the distance. Then, the numbers stopped climbing and fluctuated up and down.

"Okay!" Tony's voice trembled slightly.

Leon exhaled. "What's my thrust?"

Tony swallowed. "370 million kilograms… 370,000 tons. Jarvis estimates your single-arm strength is between 140,000 and 190,000 tons."

"That high?" Leon was genuinely surprised.

It wasn't a small number.

The Steel-Mane Superman in DC movies had a strength set at 800,000 tons.

And while that was her debut appearance, she had been exposed to the sun for over 20 years.

Leon had only absorbed sunlight for half a year.

With this power, he was already invincible on Earth.

But…

"It's still not enough." Leon clenched his fists. "Earth is just a small pond—there are giants beyond it. I still have a long way to go. I need to keep getting stronger!"

Tony, hearing Leon mumbling, rolled his eyes.

That level of humble bragging left him too drained to argue. He just focused on setting up the next test.

"Next is the punching speed test. Punch as fast as you can while still controlling your power."

Leon thought for a moment. "I usually use my biological force field to protect the surroundings when I punch. I'll strike at the maximum speed it can withstand."

Standing on the iron block, he prepared to strike.

He twisted his waist, shifted his hips, and threw a textbook-perfect straight punch.

His newly learned fighting skills maximized his power.

However, this punch was just in the air, so there was no force of tens of thousands of tons behind it.

Beep!

Tony observed from a distance.

From his perspective, Leon hadn't even moved.

Then, a number popped up on his computer—out of nowhere.

"Meters per second… close to Mach 32!?"

"Is this your maximum speed?" Tony leaned on the table, staring at the screen.

Leon misinterpreted Tony's reaction. "A bit slow."

"I could be faster, but exceeding this speed would shatter my biological force field and impact the surroundings—like what happened in the garage this morning."

Tony stammered. "It could be… faster? This is godlike!"

"God? That's nothing. This power is far from enough. When I get stronger, my biological force field will improve, and my punching speed will increase."

"Not enough?" Tony was dumbfounded. "Do you have any idea what happens when you throw a punch with tens of thousands of tons behind it at Mach 31?"

"Probably… like a small meteorite hitting Earth?"

Tony rubbed his face. "Absolutely… Jarvis, give him the exact numbers."

"Yes, sir. Mr. Leon, based on our calculations—"

"At an acceleration of Mach 31, your single-arm punch exerts more than 1,500 billion newtons in one second—equivalent to 240 Hiroshima atomic bombs detonating simultaneously."

Tony slammed the table. "That's 3.6 million tons of TNT! And that's not even factoring in the pressure of your fist hitting a small area!"

Jarvis continued. "Yes, Master Leon, you are essentially a walking high-explosive hydrogen bomb—with unlimited firepower."

Tony took two deep breaths.

Who would have thought this kid—who bickered with him daily—had such insane power?

"Do you still think your strength isn't enough? Why are you so obsessed with getting stronger? Was it because I didn't protect you enough when you were younger?"

Leon smiled. "No, Tony, you were great. You even carried me around your neck while picking up girls."

But Tony had a point.

Maybe his fear of the Time Variance Authority taking him away as a child had scarred him, making him desperate to grow stronger.

Having lived through his most powerless, anxious days, he understood—true security only came with power.

"So what's the real reason? Jealous of my charm and using super strength to beat me up?" Tony smirked.

"...Then I really should beat you up." Leon chuckled and pressed his earpiece. "Let's move to the next test. You'll see even more shocking results soon."

Over the Next Hour…

Leon tested his heat vision, freezing breath, X-ray vision, and flight speed.

Tony's screams evolved from pure horror to utter resignation.

From "Oh my God!" to "Holy shit!" to "I hate you."

Leon's 6,000-degree heat vision—which he could adjust at will? Barely useful.

His freezing breath, capable of covering kilometers in ice? Still lacking.

His X-ray vision, able to see through everything except lead? Defective, might as well ignore it.

Even his super hearing was "too noisy and mostly useless."

By the end, Tony had no thoughts left.

Just an overwhelming urge to slap Leon in the face with his size 42 leather shoes.

"So… what's next?"

Tony slumped in his chair, eyes blank, hand weakly scrolling the mouse.
