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

"Bulma, can I have this power?"

Vegeta asked out of curiosity.

Bulma shook her head repeatedly. "It's impossible. Only a mutated body like Broly's can allow the giant ape cells to survive in various parts of the body. Others can't. I have already simulated this with the computer given by Shenlong."

Vegeta didn't have any regrets.

However, he suddenly remembered another Super Saiyan form that he had seen in his fusion memory.

Super Saiyan 4!

According to my memory, to complete this transformation, one needs to first transform into a giant ape, then transform into a golden giant ape as a giant ape, and then transform into a human form while retaining the power of the giant ape.

If we only look at the fact that it requires the power of a giant ape, Broly's transformation is actually the same as the transformation to Super Saiyan 4.

Could it be that the so-called Super Saiyan 4 is actually Broly's Super Saiyan form that is cultivated through practice?

"By the way, Vegeta, although I can't give you Broly's power, I think I might be able to prevent him from going berserk after he transforms."

"really?"

"Yes, and this method might be exceptionally simple!"

Bulma said proudly: "Look, now according to my analysis, Broly went berserk because he lost his mind after transforming into a giant ape. But I remember that you were able to keep your mind when you transformed into a giant ape!"

"Of course, this is the effect of our royal blood..."

Vegeta suddenly realized something: "You're not going to use my blood to keep Broly sane?"

"Bingo! Correct."

"What a joke! How can you give your noble royal bloodline to others so easily?"

Vegeta immediately objected, but in the end, he frowned slightly and said, "However, you can continue this research. It may come in handy someday."

After that, Vegeta stayed with Bulma for a while.

Until Bulma spoke up herself: "Tell me, are you leaving?"

Vegeta touched his cheek and said, "Well, this time I plan to train in a place called King Kai where Kakarot and the others trained before."

"How long?"

"I don't know... but it shouldn't be longer than last time, and this may be my last training in this world..."

Bulma fell silent upon hearing this.

What Vegeta meant was that after this training, he might have to start looking for a way to return to his original world.

The countdown until he leaves this world is about to begin.

But soon, Bulma smiled and said, "Just go. Why are you taking so long to tell me? Are you afraid that I won't let you go?"

Vegeta looked uneasy and didn't know how to respond.

"Okay, I won't mind. You see, I have things to do every day now, so it doesn't matter if you're not here."

"Then...I'll leave?"

"come back earlier."

"Ah."

Vegeta finally stayed at Bulma's house for another day.

This was a rare day when both he and Bulma were not busy.

Vegeta accompanied Bulma to travel around the Western Capital, visiting many lively, secluded or interesting places, and also visited the university where Bulma was currently studying for a doctorate in biology.

Although Vegeta was very uncomfortable, Bulma was having a great time.

Today should be the most complete day they have spent since they met, without any purpose and with a pure mindset of having fun.

The next day, after instructing Tabur not to forget to practice, Vegeta used instant teleportation to go to the Temple of Heaven.

When he showed up at the Temple of the Gods, the God Piccolo was already prepared.

"Vegeta, the King of Hell has already promised you to enter the underworld."

"Then lead the way."

Because of his great contribution in saving the earth, Vegeta has been allowed to enter the underworld and go to King Kai's planet as a living person.

The underworld, the Yellow Spring of the Northern Milky Way.

This is a world composed of dark golden sea of ​​clouds.

Right in the center of the vast sea of ​​clouds is the palace of King Yama.

This was not the first time that Vegeta came to the underworld. He was very familiar with everything here. He flew directly towards the direction of the Hades Palace without the guidance of God Piccolo, leaving God Piccolo to chase after him.

When they arrived at the Hall of Hades, Vegeta, as a living man, scared the nearby ghosts and made them run around. Hades, who was flipping through case files, heard the noise and immediately looked up.

"Huh? Why are there living people here?"

"Yan... Lord Yanwang!"

The god Piccolo who arrived in a hurry did not have time to rest and quickly explained: "This is Vegeta from Earth."

"Oh, the Saiyan who wants to train with King Kai?"

The King of Hell had seen the application submitted by the god Piccolo before, and after a brief recollection he remembered it.

He called a red-skinned ghost messenger and said, "Follow him, he will lead you to the snake path, and through the snake path you will see the North King."

"plz follow me."

The red-skinned demon with horns on his head politely led Vegeta and the other man away.

Looking at Vegeta's departing back, Yan Wang suddenly felt a little curious.

Although he approved Vegeta's trip to the underworld, he seemed to have never even read Vegeta's file before.

The King of Hell then lowered his head and flipped through the files.

After a moment, he suddenly raised his head with a grim face.

"What's going on with that Vegeta? The underworld doesn't have any information about him?"

At the same time, under the guidance of the red-skinned ghost, Vegeta has arrived at the entrance of the Snake Road.

Looking at the endless snake path in front of him, God Piccolo couldn't help but ask: "Mr. Vegeta, your strength should be far beyond King Kai, right? Is it necessary to go there?"

"This is the training that Kakarot once did! In order to confirm the difference between me and Kakarot, and determine what I am missing, I must complete all the training he has gone through!"

As Vegeta spoke, he transformed into a Super Saiyan.

With a loud bang, a strong wind surged, and the god Piccolo and the red-skinned ghost almost fell down.

"What happened?"

The red-skinned ghost grabbed his glasses in panic and looked at the snake path.

I saw the air and mist on the snake path slowly spreading around, with a white air hole in the middle.

In the distance, the sound of explosions continued to reach the entrance of the snake path...

The last time Raditz and the others crossed the Snake Road, in order to save time, they even used the Kaio-ken and it still took them three hours to complete the entire journey.

This time, after Vegeta transformed into a Super Saiyan, it only took him ten minutes to see King Kai's planet.

When he landed on King Kai's planet, his clothes even sizzled and emitted wisps of green smoke.

"Welcome, Vegeta."

King Kai of the North, who looks similar to Xiaoqiang, already knew of Vegeta's arrival in advance and was waiting by the side with his hands behind his back.

Beside him, King Kai's pet gorilla Babrus and grasshopper Gulegli also looked curious.

"You are the King of the World?"

Whether in the previous life or this life, this was the first time that Vegeta saw King Kai of the North with his own eyes.

Looking at this guy who looked like a funny character, Vegeta couldn't help but frown.

How could such a guy create such powerful moves as Kaio-ken and Spirit Bomb?

"You should call Lord Kai! Vegeta, I already know why you are here. After all, I have been keeping an eye on you since Darius."

Vegeta smiled and said, "Then there's no need to waste my breath. King Kai, please guide me in my training."
