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

Western Capital, headquarters of the Universal Capsule Company.

In a special laboratory, Bulma with blue hair is concentrating in front of a computer.

Next to her, a huge piece of experimental equipment was making a low sound.

Ever since the incident with Lord Piccolo, Bulma has rarely gone out and has spent almost all of her time on research.

And now, her research will soon bear fruit.

However, an error message suddenly popped up on the computer in front of Bulma.

Bulma frowned, and after checking the system data, her brow suddenly became worried.

After thinking for a while, she picked up her phone and dialed a number.

"Teacher Womi, it's me, Bulma! Sorry, I ran into trouble with my experiment again. This is it..."

At this moment, Bulma's mother, Mrs. Brief, walked into the laboratory and said with a smile, "Bulma, come out and take a rest. Someone is looking for you outside."

Bulma was stunned and asked, "Who's looking for me?"

"A man."

Mrs. Brief smiled ambiguously.

Bulma was stunned for a moment, and suddenly guessed who it was!

She quickly said sorry to the person on the other end of the phone, hung up, and then ran out excitedly.

It was in the Brief's garden that Bulma met the man she had been thinking about day and night.

"Vegeta!"

Vegeta saw Bulma from a distance and didn't recognize her for a moment.

The girl who used to have long hair now has a neat and short haircut, looking like a tomboy.

Bulma flew over excitedly, not having any reservations about Vegeta at all.

Instead, Vegeta, with a helpless look on his face, held her and spun her around, then pressed her to the ground.

"Haven't we just met?"

"What? You've been gone for a year!"

Bulma said angrily, "Won't you be training all year? Didn't you think of coming to see me?"

Vegeta blushed and said helplessly: "You vulgar woman, why should I come to see you?"

Bulma couldn't pretend anymore and started to laugh secretly with her hands covering her mouth.

"You are still so stubborn. By the way, I have a guest at home who has been waiting for you for a long time."

"Guest? Wait for me?"

When Vegeta saw the guest Bulma mentioned, he couldn't help but show a look of surprise.

The person waiting for him at Bulma's house was Son Gohan, whom he had not seen for a long time.

In the evening, Dr. Brief's family invited Vegeta and Son Gohan to a family dinner.

The whole family ate and chatted together, having a great time.

"Oh my, Vegeta, you haven't eaten well in a long time?" Son Gohan looked at Vegeta who was eating voraciously with a smile.

Dr. and Mrs. Brief also opened their mouths wide.

Because at the dinner table, Vegeta ate the amount of food that 20 people ate by himself.

The only thing to eat in the Temple of Heaven was the food made with flour by Mr. Popo. Vegeta, who had not tasted delicious food for a long time, indulged himself and ate a big meal.

After the meal, several people listened to the music played by Dr. Brief and chatted in the garden for a while.

"Old man, why are you here?" Vegeta asked.

"I asked the teacher, and he told me that I would most likely meet you here, Bulma."

Son Gohan answered with a smile, but did not say the purpose of his visit.

Then, he asked Vegeta instead.

"So you're here to look for Dragon Ball again this time?"

"Well, I want to use the power of the Dragon Balls to know the coordinates of a planet. This time I plan to go to an alien planet."

Vegeta explained.

In fact, with the power of Dragon Balls, he can directly reach the planet Yadrat.

But Vegeta still wanted to rely on the spaceship to get there.

Because he wanted to use the gravity room to practice some physical training during the flight.

Vegeta's training over the years has mostly been focused on martial arts techniques and the cultivation of his chi, but his body has not been adequately trained due to the lack of challenging opponents on Earth.

Vegeta wanted to take advantage of this long journey to make up for his shortcomings in this area.

"Ah... then aren't you going to go to the universe to practice next?"

Bulma seemed helpless about Vegeta having to travel far away again.

But she suddenly blinked and said, "Right! Then I'll go with you!"

Vegeta was stunned: "Together what?"

"Let's go to space together!" Bulma said excitedly, "You don't know, I haven't been out for a long time since I studied the Saiyan cells for you! It's just right for me to go out with you this time!"

"Nonsense, I'm going to practice, why are you going with me?"

"Just take care of your practice. I have things to do myself and won't disturb you."

Bulma suddenly laughed evilly: "Besides, aren't you going to use the spaceship? That spaceship has been modified by my father and me. Without me, can you fly it?"

Veins popped out on Vegeta's forehead. After hovering on the edge of exploding with anger for a while, he said in a frustrated tone, "Go ahead if you want to!"

"Mom! Pack my bags for me!"

Bulma immediately stood up and laughed.

"Great, my daughter is going to be the first human to enter the universe!"

Mrs. Brief clapped her hands, but Dr. Brief said, "My dear, she is not the first human being. Our eldest daughter is."

"Shut up, Dad!"

Son Gohan laughed and said, "Universe, I want to go there too, but I'm too old to go. But Vegeta, I'll go with you guys to find the Dragon Balls!"

Vegeta was speechless. Why did they all follow him?

But he couldn't refuse, because now both the Dragon Ball radar and the spaceship were in Bulma's hands.

Afterwards, Son Gohan and the Brief couple went to rest.

Vegeta and Bulma went to the laboratory because the latter said she wanted him to see some research results on Saiyan cells.

In the laboratory, Bulma turned on the computer.

The picture on the screen is the image of Vegeta's cells under the microscope.

Vegeta couldn't understand it himself, so he had to listen to Bulma's explanation.

"I think I've discovered the S cells you mentioned! Look, there's a special type of cell in your blood that's present in very low amounts!"

Bulma used a small black stick to circle a special cell sample on the screen.

"Look! This is it! According to my experiments, this special cell seems to be able to store a lot of energy and proliferate due to emotions. Combined with your original description, I judge that this should be the S cell!"

So this is the S cell?

Vegeta used to think that all it took to become a Super Saiyan was enough strength and anger.

But later, combined with the memories of the soul from another world, he realized that this S cell was the key to becoming a Super Saiyan.

No wonder he couldn't become a Super Saiyan no matter how hard he tried. It was not until he lived on Earth with Bulma for a period of time that he successfully completed the transformation.

"So how many S cells do I have in my body now? How many S cells do I need to be able to transform into a Super Saiyan?"

"In my opinion, it should be at least 50%. I once made a wish to the dragon and got a computer that can simulate the changes of S cells.

According to my research, after the S cells reach 50% and the stored energy reaches a certain level, special mutations will occur due to emotions.

I guess this mutation is what you call a Super Saiyan!"

So this is ah!

At this point, Vegeta finally understood why no Super Saiyan had ever been born on Planet Vegeta.

Because it is impossible to produce S cells in the environment of Planet Vegeta.

"What about me? How many S cells do I have now?" Vegeta asked.

"Your S cells now are less than 10%, at least it was like that a year ago." Bulma laughed.

“Why is it so little?”

Vegeta was a little annoyed. He didn't expect that he had so few S cells?

But then he changed his mind and realized that after coming to this world, except for the one year at Son Gohan's house, he seemed to have been practicing all the time. Perhaps this environment could not be considered a stable and peaceful environment, so his S cells had not increased much.

But this would ruin Vegeta's plans.

The growth of S cells does not depend on how hard Vegeta practices, but is related to the environment.

In this case, how long will he have to wait before he can become a Super Saiyan?

Once he becomes a Super Saiyan, how long will it take before he has enough strength to rival that world's Kakarot?
