Universal Pokémon Master

"Ah!!! Huh! Huh! Huh!" In a quiet, small town, a scream suddenly echoed, sounding as if it came from a young boy. The shout startled a group of weak Pokémon nearby, causing them to flee in fear.

"Ash, what's wrong? Are you okay?" Inside a house in that same small town, a mature woman with a good figure, dressed in pajamas, called out in concern toward a locked bedroom door. Unfortunately, since the door was locked, she couldn't get inside.

"Mom, I'm fine. It was just a nightmare. Go back to sleep!" Ash replied, his voice shaky from the other side of the door. He lay in bed, drenched in sweat.

"Alright, but if anything happens, come to me. I'll help you with whatever you need!" Delia said, still worried, before returning to her own room.

Ash lay on his bed, staring gloomily at the ceiling, his expression far too serious for a typical five-year-old.

In reality, this Ash was not an ordinary boy. He was a transmigrator—someone whose soul had been reborn in this world. In his previous life, he was known as Mandy, an orphan from Earth. Despite his difficult start in life, Mandy was incredibly intelligent. With his sharp mind, he managed to amass a substantial fortune in just seven years!

Though he wasn't super rich, he lived comfortably and lacked for nothing. At the age of 26, Mandy entered a relationship, and this event would go on to change his life forever.

The woman Mandy fell in love with appeared to care for him, but she was only after his money. Mandy, however, didn't see through her true motives. For three whole years, she deceived him, playing the role of a loving partner. When Mandy turned 29, she vanished without a trace, taking all of his wealth with her.

Devastated, Mandy withdrew from reality, finding solace in the world of anime. Although he had lost all his money, his house remained, the one asset the woman hadn't taken from him.

Mandy began earning money online to support himself, leading a relatively stable, albeit isolated life. Just when he thought things would continue like this indefinitely, fate intervened. One day, Mandy saw the very woman who had betrayed him three years earlier.

Upon seeing her, all the anger and bitterness that he had suppressed for years rushed back to the surface. As an orphan, Mandy had always cherished family, love, and trust. No matter how much the woman had hurt him, he had endured it, hoping for some kind of resolution. But now, those feelings had twisted into a desire for revenge.

It turned out that after stealing Mandy's money, the woman had gone abroad to invest, only to lose most of it. She returned to their country with the little money she had left, planning to open a clothing store.

After Mandy saw her again, he couldn't sleep for days, consumed by thoughts of vengeance. Eventually, he decided to act. One night, armed with a blade, Mandy confronted the woman. With a cold expression, he stabbed her, plunging the knife straight into her heart, ending her life.

Once someone kills, it's easy for that act to become addictive—depending on how they feel afterward.

For Mandy, after killing the woman who had deceived him for years, he felt an odd sense of satisfaction. It was as though a heavy weight had been lifted from his chest. From that moment on, Mandy started targeting other people—those who had escaped justice due to wealth and influence.

As time passed, Mandy lived this life of revenge for an entire decade. By now, he was 39 years old. Over the ten years, he had transformed into a first-class assassin.

Once Mandy set his mind on something, he was determined to become the best. Every day, he sharpened his killing techniques and trained his body. After a decade of this lifestyle, Mandy had killed so many people that he lost count.

He had worked as a mercenary, a hitman, and even carried out terrorist operations. One of his most notable feats was single-handedly dismantling a large drug cartel, wiping out all the dealers and traffickers involved.

However, even in the underworld, things don't always go according to plan. During an attempt to assassinate a major drug lord, Mandy was betrayed by his employer and the authorities. A missile was launched to eliminate him, and it tore him apart.

But Mandy had anticipated this possibility.

He always carried a time bomb during major missions—a powerful explosive that served as a backup plan in case things went south. If Mandy was going to die, he planned to take his enemies down with him.

Just before the missile hit, Mandy activated the bomb. In an instant, the explosion swallowed everything around him, wiping out over 100 people involved in the drug trade and other heinous crimes.

As the explosion obliterated the drug cartel, something strange happened. A massive aura of death began to gather, surrounding Mandy's soul and carrying it away from Earth.

When Mandy regained consciousness, he realized he had been reincarnated. He was now an unborn child inside the womb of a woman named Delia. By the time Delia was seven months pregnant, most of Mandy's new body had already formed.

He could hear voices from the outside world, and eventually, he pieced together the truth: he had been reborn into the world of Pokémon. Mandy was shocked. He had never imagined that the fictional universe he once loved could actually exist.

This world of Pokémon was filled with strange creatures, each possessing unique powers. In this world, a profession called Pokémon Trainer had emerged—trainers who captured and trained these creatures to grow stronger through battles.

However, this wasn't exactly the same Pokémon world Mandy had known. Things were different, and the events of this world couldn't be predicted by the anime plots he vaguely remembered from his past life. After all, he had stopped watching anime ever since he became a killer, and most of the details were now forgotten.
