Dragon Ball: What if Son Goku became an evil villain?

"Vegeta, take this."

As they parted, Bulma pressed a syringe into his hand.

"what is this?"

"Remember the super S cells we found in the hair you brought with you? This potion can transform the S cells in your body into super S cells, which can theoretically make you stronger!"

"I don't need this kind of thing to become stronger!"

Vegeta wanted to refuse, but when he saw Bulma glaring at him, he reluctantly put the syringe into his pocket.

Then, other people came over.

"I didn't expect you to be from another world. Now I have no chance of defeating you." Kakarot looked regretful.

Vegeta looked at Kakarot in this world with a complicated expression.

"After I leave, the protection of this world's Earth will be left to you! If you can't do it, I might come back and kill you!"

"Don't worry! When Raditz is resurrected, I will protect the earth with him." Kakarot replied with a smile.

"elder brother……"

On the side, Tabor also looked regretful.

Compared to Kakarot, he felt more lost after knowing the truth.

Because Vegeta is his last relative in this world, after he leaves, he will have to live alone again.

"Tabel, don't give me that look! After I leave, you will be the last prince of the Saiyans! Live like a prince!"

"Yes!"

Vegeta looked around and asked, "By the way, where's Broly?"

"He's still blaming himself for destroying Namek."

"Let him recover soon! Although Frieza is dead, there will be more powerful opponents coming! You will use Broly's power."

Piccolo asked, "Are you talking about the Androids and Majin Buu? They won't succeed as long as we're here."

Vegeta glanced at Piccolo but didn't deny his words.

Compared to his world, the warriors on Earth in this world are indeed much stronger.

Not to mention Broly, even Piccolo, who has fused with many Namekians, is powerful enough to rival a Super Saiyan.

"I hope you will keep your promise. Then I will leave."

Vegeta said, and entered the super time machine.

Through the glass cover of the time machine, his eyes flashed over everyone one by one, and finally stopped on Bulma.

Although she had been smiling before, Bulma's eyes finally turned red when they parted.

"Goodbye, Bulma of this world..."

Vegeta waved to Bulma and started the time machine.

As the engine began to buzz, Bulma finally shouted, "Vegeta, we must save that world!"

The Super Time Machine slowly flew up amid the farewell gazes of the crowd. Vegeta took one last look at the world, and then a distortion arose around the Super Time Machine, and it disappeared into the air.

……

New Namek, where it all began.

When Vegeta's super time machine finished traveling, the first thing he saw was the desolate scenery of New Namek.

"Is it Kakarot? He's been here?"

After putting the time machine into the universal capsule, Vegeta immediately saw traces of a battle not far away.

Although more than ten years had passed, he still remembered the place where he appeared. It was the village where the great elder Muli of the New Namek people lived.

However, the once peaceful and harmonious village is now littered with collapsed houses and huge pits.

From time to time, you can still see dead Namekians.

Vegeta checked their bodies and found that most of them were not killed in one blow, but were slaughtered in a massacre.

The body should have died not long ago, most likely within these few days.

New Namek is a planet located on the border of the Milky Way. The Namekians chose this planet as their new home because of its location where they would not be disturbed.

So the only possible murderer Vegeta could think of was Kakarot!

Only he has the motivation and ability.

Next, Vegeta went to check out several other villages.

Unfortunately, all Namek villages were attacked and no one survived.

Both the elderly and children were brutally murdered.

Vegeta even found the Dragon Balls turned into stone, proving that the Namekians should be completely extinct.

"Damn it Kakarot! Doesn't he want anyone to have the chance to use the Dragon Balls again?"

After confirming that the planet had become a dead star, Vegeta planned to use instant teleportation to return to Earth.

However, when he tried to lock the position of the earth, he found that there was no sign of living people on the earth!

Vegeta's eyes suddenly fixed.

He confirmed it several times, but got the same result every time. Although the Earth did not become a dead planet and there were still living things, there was indeed no trace of human beings.

Could this also be Kakarot's doing?

Vegeta randomly locked onto the breath of a creature and instantly moved over.

Earth.

The dilapidated city roads are covered with withered yellow weeds, and are littered with broken vehicles and collapsed and tilted houses.

And in the center of the city, a huge deep pit can be seen.

Near the deep pit, there are traces of high temperature burns.

A vulture was standing on a rotting corpse, gnawing at the remaining flesh and bones.

At this moment, a figure suddenly appeared behind it, scaring the vulture so much that it flew away quickly.

Vegeta was almost stunned when he saw the scene in front of him.

When he was injured and sent out of the earth, such a scene had never appeared on the earth.

Although the crazy Kakarot killed all the Z warriors except himself, at least at that time, he did not attack ordinary people.

How come the earth has become like this now?

Could it be that the time was wrong? The time he returned was actually a long time after he left?

With doubts in mind, Vegeta flew towards the Western Capital.

They passed many villages, towns and cities along the way, all of which were in the same dilapidated state and filled with endless corpses. Many of the corpses had no visible wounds, so Vegeta couldn't be sure how they died.

Apart from these, his only gain was confirming the time in the current world.

In a relatively intact suburban cottage, Vegeta saw an electronic clock that was still running. The time displayed on it was exactly one month after he used the Dragon Balls to leave this world.

Bulma from the other world was not wrong, her super time machine really sent herself back to one month after she left this world.

But in just one month, why did the world change like this?

And Bulma...

Is she also...
