Goku was expecting for Raditz to start away, but he appeared in front of Goku and sent Goku flying through a room. When Goku got up, he found himself in a room where a giant tank held a brain an old man that looked like an old scientist.
"YOU! You did something to my brother, change him back"
The old scientist just smiled. Then Goku heard a voice who he thought was the old man but realized was the brain itself.
"Your brother makes a good servant, how would you like to join him?"
This angered Goku and he got up
"KAIO-KEN TIMES FOUR"
As Goku was about to strike the brain, he was shot from behind and fell face down. Goku got up and saw his brother in his kaio-ken x5 form.
"Let me introduce myself, I am Dr. Wheelo. I'm going to conquer Earth as my own"
Goku struggled to get up and looked at his brother.
"Fine that's the way you want to play, KAIO-KEN TIMES SIX"
This brought Goku's power level to 168,000. The brain known as Dr. Wheelo wasn't surprised to Goku's increase in strength.
"Oh you can master Kaio-ken up to 6? So can your brother but his kaio-ken is stronger"
In that moment, Raditz power level grew, it was at 180,000. Goku knew that Raditz had finally kept up with him. Goku couldn't go any higher than six. he got in position and began rushing at his brother, who easily blocked very hit and smiled in doing so. Goku kept trying to land a punch on his brother til suddenly, Raditz's knee drove into Goku's stomach. Goku fell back, he was in great pain. Raditz then continued with a knee to the face and ending with a kick to the body sending Goku flying. It wasn't good for Goku, his brother was too strong especially with the increase of strength that the device on his head was giving him. Goku got up, he sped toward his brother and rushed him but Raditz had the upper hand as he was in kaio-ken x6 the whole time. In every attempt for Goku to hit Raditz, Raditz deflected the hit and countered with a strongly packed punch or kick. After so many failed attempts, Goku was finally sent to the ground again. He managed to pull himself up, he looked up and saw as his brother descended to the ground again. Once Raditz touched ground, he extended both arms toward Goku. Goku who finally got up realized what was going to happen next. Raditz got in his hands in position and started firing a barrage of ki blasts at Goku who took the hits directly without effort of blocking it, eventually was walking shirtless. He walked toward his brother as Raditz kept shooting at him. At one point fell on one knee as Raditz kept shooting at Goku. Then with a determined mind set, Goku got up and kept going limping as he went to his brother.
"Stupid Goku, you won't last much longer at this rate, you might as well give up now"~Dr. Wheelo.
The brain just kept on laughing, he knew he had won. He felt that victory was in his hands. Then Goku finally made it to his brother. Once there, Raditz stopped with the ki blasts. They were locked in a stare down. Neither of the two saiyans made any movement and nor was there an expression on their face. Then at the speed of light, Goku launched himself at his brother. Raditz on the other hand put his power in a single punch and jabbed Goku in the ribs. Goku grabbed onto the device on Raditz's head. He hold on as he pulled it off while Raditz kept punching him at a constant rate. Goku felt himself going unconscious due to the Raditz's hits. He felt his life leaving him, blood was running down his mouth. Then one effort, he gave one hard tug and pulled off the device but not before Raditz gave Goku a very hard jab to Goku's few good ribs remaining. Goku landed on his back with a big crash, Raditz white eyes began to have their pupils being restored once again. Raditz realized what had happened
"I'm sorry Kakarot" he whispered to his knocked out brother.
Raditz then looked at Dr. Wheelo with an angry expression.
"YOU! YOU'LL PAY FOR WHAT YOU DID!"
In that moment, he powered up in his base max form which was a level of 24,000 again. Then from some reason Raditz's base power began to decrease, his body was fatigued from the ki blasts directed to Goku. He was under 20,000 and dropping.
"KAIO-KEN TIMES SIX"
The familiar red aura covered Raditz and he pursued the doctor. In that moment, the brain began to move. In moments, the brain was placed in a navy blue robot. Once in the robot suit, the brain had access to a built in scouter. The scouter detected a power level of 105,000. His base was only at 17,500. Raditz knew his body was weak but he couldn't give up just now. He flew at Dr. Wheelo, he charged up his purple ki.
"SATURDAY CRASH"
He sent a bigger version of his attack, Dr. Wheelo countered the attack with his own attack.
"Fool, did you think I was not prepared for you if you got out of my control? I made sure the suit was strong, initially it was supposed to be strong enough for attacks as high as 50,000 but thanks to technology I doubled the shield and endurance. This armor can withstand attacks around the power level of 100,000. Your attack won't do nothing"
Raditz kept pushing his attack still trying to break through the armor. He felt his body giving out, he couldn't hold much longer. Then Dr. Wheelo with a flick of an arm, he swatted Raditz away like a fly. he landed hard against the glacier-like wall and his red-aura went away. He then fell to the ground unconscious. Dr. Wheelo went ahead to kill Raditz. Then old scientist tried to reason with Dr. Wheelo.
"But sir, he can be a useful servant again like he was"
Dr. Wheelo grunted "impossible, this has proven he's too strong to control. I just needed him til the suit was ready to use. He's no longer required"
Then he looked at the elderly scientist "you too have no purpose to me anymore. Good bye"
Without warning, Dr. Wheelo got rid of his partner in one blast.
"Now to finish this saiyan"
As Dr. Wheelo was approaching Raditz, his scouter began to beep. His scouter detected a power level of 20,000 and it was increasing. He turned around and saw Goku standing up, he didn't seem to be worn out anymore.
"So you still have a little more fight in you?"
The scouter detected that the power kept growing and growing, it went over 22,000. This left Dr. Wheelo a little concerned.
"You should have rolled over and died when you had the chance"
Dr. Wheelo then extended his claw and shot a ki-blast a Goku. There was dust. Once the dust uncleared, Goku was seen standing but he was shirtless this time.
"Impossible? I was sure Raditz beat the living lights out of you. How are you still able to fight?"
His scouter showed Goku's power level at 24,000 and was still growing. Goku then smiled and took a step closer to . The scouter had finally stopped moving, was taken back that Goku was fighting at a level of 25,000.
"Argh. Even at 25,000 you still can't beat me"
Goku replied calmly "I won't know til I try"
put his claws together preparing his attack. He was preparing for his planet geyser technique, once charged it at Goku. Goku was ready for the attack,
"KAIO-KEN TIMES FIVE"
He launched a Kamehameha. was overwhelming Goku, Goku knew he had to put his max in the Kamehameha.
"TIMES SIX"
This caused his Kamehameha to get bigger but the Planet Geyser still seemed to be overwhelming him. was viewing Goku's power level, his level was at 150,000. His Planet Geyser was at 165,000. He knew Goku couldn't go any higher than kaio-ken x6. He laughed knowing he had the upper-hand.
"Give up saiyan, there's no way you can win"
Goku was under a lot of pressure
"I won't give up when the people of earth depend on me"
Goku knew it was time to go past his limits even if it meant that he had to die. He knew he had to to not give up. In one mighty push, Goku gave it all he got
"KAIO-KEN TIMES...E-E-EIGHT!"
