I, the younger brother of Superman, ended up with a Thanos template.

But to everyone's surprise, David grew stronger with each battle, completely overwhelming Brainiac.

Blood rained down from the sky. Brainiac's chest caved in, his tall body sent flying backward. David, on the other hand, radiated purple light, like a god born from a star, his aura astonishing.

"On this technologically barren planet, there is actually someone like you."

Coughing up blood, Brainiac was forced back by David's burning gaze, the pain of his burned arms causing his brows to twitch.

“I hate surprises, but this time is an exception.”

His arms were burned raw, and there was a burnt smell.

David threw a punch, the force of which created a tangible shockwave that, accompanied by a strong gust of wind, broke Brainiac's arms as he tried to block.

He was about to attack again.

Brainiac's eyes narrowed, and a powerful, overwhelming mental force slammed into David's mind. David felt as if he had been struck by an invisible force; his head jerked back, his brain buzzed, and his movements immediately stopped.

Quickly pulling back, Brainiac gained a moment to catch his breath. New skin covered his wounds, broken bones reconnected, and his injuries healed rapidly, as if time had reversed.

"An impeccable body." He stared at David's body with a hungry gaze.

Many physically powerful cosmic races are mentally vulnerable, but David does not have this problem. His raging mental power is like a dam that has been struck without moving.

A few waves splashed over the dam, but did not cause any real damage.

"I really want to learn from you."

How can you maintain a superior attitude even when you're at a disadvantage in battle?

Shaking his head, David sneered, approaching like a comet. His fist, as fast as a streak of light, pierced through his defenses, and with earth-shattering force, it slammed into Brainiac's head, producing a crisp cracking sound.

Brainiac was like an ordinary person who had been hit hard on the head with a baseball bat; blood splattered on his head for a moment, and his brain was concussed.

However, he did not lose consciousness as a result.

His unique physiological structure allows him to think and control his body using his spine even after losing his head.

"You stupid creature!"

However, Brainiac wiped the blood from his face. He knew exactly how wretched he looked, and he roared in fury.

"You think you can beat me?!"

This is nothing more than an insignificant biological shell of mine.

No one has ever made him so miserable since his birth. He is regarded as a terrible nightmare by many life-bearing planets in the universe. He has destroyed countless worlds and wiped out countless lives from this garden called the universe!

And now, a guy who only knows how to swing his fists and has no knowledge of even a single galaxy in his brain beat him until his face was covered in blood.

"An artificial intelligence is furious."

What a rare sight!

David rushed in, his powerful punches shattering Brainiac's defenses, and grabbed him by the neck.

"Idiot, are you trying to suffocate me?"

"Foolish experience," Brainiac thought, "he's not some inferior being that needs to breathe." His face contorted, he struggled to speak but still mocked David, mustering all his strength to throw a punch at David's chest, but it was caught.

Bang!

The two men clashed, creating shockwaves.

"I forgot about that."

David twisted it hard.

Pain spread throughout his body, and Brainiac's body was twisted into an immobile position by his joints, temporarily unable to move.

"However, your body is still within the scope of the biology knowledge I acquired in high school."

When Brainiac's consciousness descended upon Earth, he must have digested everything on the Earth network in an instant, and he should understand what "high school" means.

"All your efforts are in vain."

Brainiac looked furious, and even when David restrained him, he still didn't drop his condescending attitude, as if a superior being were looking down on an ant.

"I possess endless knowledge; power can never surpass wisdom."

"So what's going on now?"

David asked the question casually, as if he didn't understand the situation.

"Everything is still under my control, and I have already set my sights on you."

Today is not the end, but the beginning!

Brainiac's eyes flashed with greed and murderous intent as he glared and growled.

"One day I will return to this primitive and backward planet. At that time, flames will burn this barren world, and you will accept your fate and become the material on my experimental table. All the mysteries of your genes will be revealed to me!"

After saying that, his eyes rolled back, and a burnt smell came from his head and spine; he had destroyed his own body.

Brainiac calculated his odds of winning and concluded that once David's potential was unleashed and his power increased, his chances of winning were less than five percent.

He was a cold and rational being, unwilling to gamble with the possibility of further humiliation and disgrace on a slim chance, and simply abandoned this biological shell.

David frowned, not expecting Brainiac to be so decisive. He released his grip, letting the body fall to the ground, where it met the gaze of the mechanical superman.

The mechanical superman opened his mouth, staring in astonishment at the corpse of his creator, as if a computer had encountered an unsolvable problem and crashed.

He knew that this was merely a temporary shell of his creator.

But his creator actually lost on this primitive and backward planet, which is simply impossible!

Bang!

The mechanical superhero was knocked unconscious. Clark, at Jor-El's signal, took action, clutching his aching chest, and staggered over. After being exposed to the yellow sun for a while, his injuries recovered considerably.

Will he come again?

Standing beside Brainiac's body, Clark's face was grim. In truth, he knew the answer to that question without a doubt.

But he hoped to receive some good news.

"Brainiac is unkillable."

Joe Al paused for a moment, then spoke.

"Countless people in the universe have seen Brainiac's biological shell, but no one has ever seen the real him, and no one knows where his true form is."

After saying that, he looked up at David in the sky, his eyes filled with undisguised surprise.

Brainiac's robots, which were tasked with destroying the world and collecting samples of civilization, had encountered formidable enemies that he couldn't defeat, requiring Brainiac's personal intervention.

But no one ever thwarted Brainiac's objective, and even killed one of his biological shells.

Like Brainiac, Jor Al couldn't believe that his son Clark's brother was a life born from this tiny planet.

He originally launched Clark to Earth so that Clark would be safe from any danger and could become a god of Earth. However, he did not expect that there was an Earthling in the family that adopted Clark who had even greater potential than Clark.

"Don't worry too much."

Hearing their conversation, David landed beside them and comforted the worried Clark, whose brow was furrowed.

"Perhaps Brainiac will use a more powerful bio-shell next time he comes, but the power will still be limited."

He admitted that Brainiac might be an unkillable cosmic nightmare.

Brainiac is like the Marvel Universe version of Ultron. Even killing an intelligent life form like Ultron on Earth, which is full of the internet, is so difficult, let alone Brainiac, who is connected to the entire cosmic network.

That's almost impossible.

But Brainiac's strength is about that level.

David's eyes flickered.

He was slightly stronger than a typical Kryptonian son, but not by much. He looked up at the sky above Earth and flew rapidly toward the spaceship.

"By the way, the Metropolis, we're almost there in an hour!"

Clark finally snapped out of his daze, realizing that he had just defeated a world-destroying enemy only to learn that they might attack again. He quickly boarded the spaceship in Earth orbit with David.

We arrived at the central control room.

Cities, each encased in glass and originating from a destroyed alien civilization, are displayed like collectibles on a bright and clean counter.

The two found Metropolis, and with Joe Al's guidance, they used the ship's shrinking technology to reverse the process just before the one-hour permanent shrinking period was about to expire, restoring Metropolis to its original appearance.

The metropolis was both shrunk and enlarged, and the power lines and drainage systems beneath the city were all destroyed. Reconstruction would take a great deal of effort and time.

"Thank you, Superman and the Superman."

Although their enormous faces really startled me when they appeared in front of the glass case like the towering giant Atlas.

But I'm grateful to them for saving my life and my family's life, and I'm grateful to them for saving this city!

However, compared to permanently living in a glass dome as a being smaller than a mite, becoming an alien's collection and plaything, the people of Metropolis are filled with the excitement of surviving a catastrophe, knowing they can still feel the sunlight and air of Earth!

They were incredibly grateful to David and Clark.

Mayor Max Minnow delivered a passionate speech in the city center square, where Metropolitan City residents gathered, expressing his gratitude to the superhumans who surpassed him.

Clark was delighted and relieved to see the Metropolis reappear on its original site. He had almost brought Brainiac there, but thankfully the city was saved in the end.

"The Metropolitan Museum of Art will award us for our efforts in saving the city."

David, are you really not coming with us?
