Vegeta and Nappa arrive on Earth

When Son Goku returned home and saw Piccolo there, he smiled. "You're here."

Piccolo asked, "Was that energy just now yours?"

Son Goku said, "That's right. Now you know how big the gap between us is, don't you?"

Piccolo said, "Don't get too smug, Son Goku. I'll surpass you sooner or later."

Son Goku smiled. "Then I'll look forward to it."

Piccolo asked, "Where's the Gravity Room you mentioned?"

Son Goku said, "My father-in-law is building it. It'll take a few more days."

"All right, I'll come back in a few days," Piccolo said.

Son Goku nodded. "You're welcome anytime."

Piccolo said nothing in response. He got up and left.

A few days later, Dr. Brief finished building the Gravity Room, which could reach a maximum of one hundred times normal gravity.

After using Instant Transmission to notify Piccolo, Son Goku entered the Gravity Room with him.

Son Goku set his Weighted Clothing to thirty-one times normal gravity, told Piccolo to get ready, then set the Gravity Room to ten times normal gravity.

In an instant, Piccolo was flattened against the floor, unable to move. Seeing this, Son Goku had no choice but to turn off the gravity and let Piccolo train in the Gravity Room at his own pace.

He had Briefs build another Gravity Room for himself. He also brought Krillin, Tien Shinhan, Yamcha, and Chiaotzu to his home so they could train alongside Piccolo and Raditz in the Gravity Room.

At first, everyone was afraid of Piccolo and Raditz. Only after Son Goku reassured them did they enter the Gravity Room to train with the two.

Son Goku, meanwhile, trained alone in a separate Gravity Room.

My Weighted Clothing can reach three hundred times normal gravity, and the Gravity Room goes up to one hundred times. Combined, they can reach thirty thousand times normal gravity. That should be enough until Cell, Son Goku thought.

After that, everyone began training hard.

In his spare time, Son Goku had Piccolo help look after Son Goshin and Son Gohin. Piccolo adamantly refused at first, but in the end, he came around despite himself.

Two years later, Son Goku had fully adapted to thirty thousand times normal gravity, and his power level had reached an astonishing thirty million. Of course, Son Goku didn't know the exact number himself, though he could roughly guess. He still couldn't transform into a Super Saiyan, but he didn't mind. His current power was more than enough.

By then, Piccolo had adapted to fifty times normal gravity, and his power level had reached twenty thousand. Raditz was rather lazy, but he had still adapted to thirty times normal gravity and reached a power level of fifteen thousand.

Krillin had adapted to forty times normal gravity and reached a power level of four thousand five hundred. Tien Shinhan had also adapted to forty times normal gravity, reaching five thousand. True to their Half-Saiyan heritage, Son Gohin and Son Goshin had both adapted to forty times normal gravity over those two years, reaching power levels of four thousand. Yamcha had adapted to thirty times normal gravity and reached three thousand five hundred, while Chiaotzu had also adapted to thirty times normal gravity, barely reaching three thousand.

That day, everyone was training as usual, but before long, they sensed two evil energies about to arrive on Earth. Knowing that Prince Vegeta and Nappa had come, they all left the Gravity Room and headed to the pair's landing site with Son Goku.

Before long, everyone arrived at the landing site.

A moment later, they saw two spherical spacecraft tear through the atmosphere and slam into the spot they had predicted.

The hatches of both spacecraft opened. Vegeta and Nappa stepped out to find everyone staring at them as though they were monkeys on display.

Vegeta and Nappa flew out of the craters and landed before the group. After looking them over one by one, Vegeta fixed his gaze on Raditz. "You've got some nerve, Raditz, daring to betray me."

Raditz replied, "Prince Vegeta, a wise man knows when to change sides. My little brother Kakarot is invincible. He'll lead us Saiyans to glory, instead of leaving us wagging our tails and begging for scraps under Frieza."

Nappa flew into a rage. "Raditz, you worthless trash! How dare you call Prince Vegeta a dog? You must have a death wish!"

As soon as he finished speaking, he noticed Vegeta glaring daggers at him and hurriedly added, "Prince Vegeta, I wasn't the one calling you a dog. Raditz was the one who called you a dog."

That only made Vegeta angrier. "Shut up, you idiot, Nappa!"

Then he turned to Son Goku. "You must be Kakarot. Tell me, how do you want to die?"

Son Goku smiled. "You want to kill me? Take a good look at the situation first!"

Then he addressed the others. "Everyone, release your energy. Let our friend Vegeta get a good look at the results of your training over these past two years!"

At his words, everyone released their energy one by one.

As they began releasing their energy, Vegeta and Nappa were dismissive at first. But when they saw that Raditz's power level had reached fifteen thousand, their composure vanished.

When he saw that Piccolo's power level had reached twenty thousand, Vegeta shouted, "Impossible! Absolutely impossible! We Saiyans are the warrior race! How could a Namekian's power level be higher than mine, a Saiyan's? Oh, I get it! You must have used those wishing orbs to raise your power levels. Damn it!"

Upon hearing that Piccolo was a Namekian, Krillin said, "No wonder Piccolo looks different from us."

Piccolo's expression grew complicated.

Son Goku smiled. "Piccolo, once this fight is over, I'll go to Planet Namek with you so you can reconnect with your roots."

Piccolo nodded.

Nappa whispered to Vegeta, "Your Highness, this isn't looking good. Raditz's power level is higher than mine, and that Namekian's is higher than yours. They've got a whole bunch of others helping them, too. We're no match for them. We should retreat."

Vegeta said, "Don't panic. We can still transform into Great Apes. Then you can take out the Namekian, and I'll take out Raditz in his Great Ape form. That solves everything, doesn't it?"

Nappa said, "You're so clever, Prince Vegeta. Why didn't I think of that?"

Vegeta said, "I keep telling you to use your brain more, but you never listen."

Nappa said, "You're right to reprimand me, Prince Vegeta."

Watching the two whispering to each other, Son Goku smiled. "Have you finished discussing your strategy?"

Vegeta said, "We don't need a strategy to deal with trash like you."

Son Goku looked at Vegeta as though he were an idiot.

Vegeta flew into a rage. "What's with that look?"

Son Goku smiled. "It's the look you give an idiot."

Furious, Vegeta was about to attack.

Son Goku said, "Hold on. If we're going to fight, let's go somewhere else."

Vegeta said, "It makes no difference where."

Son Goku said, "You and Nappa, follow us."

Then Son Goku and the others flew toward the wasteland, with Vegeta and Nappa following behind.
