Goku's long lost brother Raditz has suddenly arrived on Earth. The first warrior to greet the Saiyan from outer space was none other than Piccolo, Goku's archenemy. The two warriors had a brief conversation where Piccolo attempted to blast the evil Saiyan. However, Piccolo's power was nowhere near strong enough to kill Raditz. As Raditz went to eliminate Piccolo, he became distracted when he sensed Goku moving towards Master Roshi's island. Upon arriving on the island, Raditz told Goku the origins of their race and that they were brothers. Goku was shocked and in denial of this revelation and challenged him to a fight.
"You fight me? This planet is full of comedians." Raditz stated with a laugh. "Some green man tried to fight me a few hours ago and he couldn't put a scratch on my armor." Raditz further explained.
Everyone became shocked that Piccolo had already engaged Raditz in combat and did absolutely no damage to him. Goku stood firm and approached Raditz and threw his right elbow at his alien brother. Raditz knew the attack was coming and side stepped Goku and smashed him with his tail. The tail whip sent Goku flying into the side of Roshi's house. The wood on the pink house shattered and warped as Goku lay in a pile of wreckage.
"That's it! I'll show you not to mess with Goku!" Krillin screamed as he rushed Raditz.
"Pathetic. Absolutely pitiful." Raditz said condescendingly as he punched Krillin through the second story window of Kame House. Bulma and Master Roshi now became terrified as the stranger was able to easily beat up Krillin and Goku. "Now Kakarot get up! Clearly you lost sight of your mission. Tell me what happened to you as a child." Raditz demanded as he walked over to Goku.
"What do you mean," Goku questioned from the ground. "Why do you keep calling me that name? Raditz then picked Goku up and he began hitting him with his left arm trying to knock some sense into him.
"Did you ever hit your head as a child?" Raditz questioned his brother in between rounds of beating him senseless.
"Yeah a long time ago I fell into a ravine and smashed my head on a rock. That's all I remember about that day." Goku explained.
"Damn it! That fall scrambled your programming. You were supposed to enslave this planet so it could be sold to the Planet Trade Organization." Raditz explained to the battered Goku.
Krillin was severely injured after crashing through the second story window of Roshi's house. Gohan was hiding upstairs and was horrified when he saw Krillin's injuries. Seeing the muscular alien beating up his dad caused Gohan's anger to start building. The angry child ran out the front door and approached Raditz.
"Leave my daddy alone you monster!" Gohan screamed as he attacked Raditz.
"Looks like you did something useful Kakarot! Your kid has a power level of six hundred when he's angry!" Raditz said excitingly as he dropped Goku and hit Gohan with a swift kick. The blow knocked Gohan out and caused his hat to fly off towards Bulma. "Maybe I should teach you a lesson by taking your son. If you don't kill one hundred humans I'll kill your son." Raditz threatened.
"No! You can't take him. What kind of brother are you?" Goku questioned.
"I am the Saiyan warrior Raditz! I will do whatever I have to for the success of my mission. Family means nothing to me." Raditz explained as he picked Gohan up and levitated in the air. "Come find me in the Northern Plains after you kill one hundred humans Kakarot. Or else he dies." Raditz reiterated his previous threat. With that, Raditz flew off towards the location where his ship had landed. Goku then blacked out for what seemed to be an eternity.
"Chi-Chi is going to be devastated when she finds out Gohan has been kidnapped Bulma." Master Roshi said to the blue haired girl.
"We have to help Goku and Krillin with their injuries. Your house is in pretty rough shape too." Bulma said moving towards Goku.
"This planet never seems to be completely at peace. Why are all the crazy people attracted to causing Goku pain and suffering?" Master Roshi questioned himself as he moved inside his house to attend to the injured warriors.
A few hours passed and Goku regained consciousness. At the same time, a familiar warrior landed on Roshi's island. The warrior had light skin, three eyes, green pants, and a white shirt. That person was Tien Shinhan, and he had sensed Raditz's strength from where he was training. Everyone was shocked to see Tien after a five year absence.
"It's been a long time Goku. I see that the strange power I sensed has already been here." Tien stated walking into the damaged living room.
"He took my son Tien. We have to stop him before he hurts Gohan." Goku grunted in pain.
"I'm glad I still have one more Senzu Bean left in my pouch." Tien explained as he took out his final Senzu Bean. "Take it Goku so we can go get your son back." Tien offered his friend.
"Thanks Tien. You're a life saver." Goku thanked Tien as he swallowed the bean. Within a few moments Goku was fully healed and ready to run after his evil brother. "I'm ready whenever you are Tien. You've gotten a lot stronger since the last time I saw you. I think the two of us can beat him." Goku said reassuringly.
The two warriors walked outside ready to take off in pursuit of Raditz. Bulma and Master Roshi wished them luck and said they would continue to treat Krillin's injuries. Before they could leave someone else arrived on the island. It was Piccolo and he looked angry to see everyone.
"I don't have time to deal with you right now Piccolo." Goku said bluntly.
"I know what happened here. That alien encountered me first. I was lucky you distracted him by his machine sensing your ki. Otherwise, he would've killed me and the Dragon Balls would be useless." The green man explained. "I'm going with you two to fight him. He needs to be taught a lesson on who the true ruler of this planet is." Piccolo stated with a laugh.
"I don't know if we can trust him Goku. What if he betrays us after we take that guy out?" Tien asked with worry on his mind.
"We have no choice Tien. It's either we trust him or we could possibly die trying to save Gohan." Goku explained. "Fine Piccolo. We'll team up this one time. After it's over we'll settle our score." Goku agreed. The three warriors flew away in hot pursuit of Goku's Saiyan brother.
Raditz had gotten back to his space pod after an hour or so of flying. His nephew was still knocked out cold. Raditz went back over to his pod and began entering some information into the computer of the ship. "I knew it. If Kakarot had come here in a pod like mine it should still be around here somewhere." Raditz had used his pod to attack as a homing beacon that would attract Goku's abandoned Saiyan space pod. "It's only a matter of time before his ship makes its way towards this location. When it gets here I'm going to send this little brat off to a planet far away from here so I can train him properly." Raditz thought to himself diabolically. Within a few minutes Goku's old ship had arrived. Saiyan technology could move at much faster speeds then a ship that was engineered by humans.
"This is great. Vegeta and Nappa will be proud when I present this child to them after he is trained appropriately. Kakarot may be a lost cause, but his son can be easily influenced." the evil alien said as he input coordinates for the planet Arlia in Goku's pod. Raditz then proceeded to pick Gohan up and place him inside of his father's old ship. The door closed and Gohan regained consciousness.
"What's happening?" Gohan said while crying inside the ship. "Let me out of here right now you monster!" Gohan screamed banging on the window.
"You're going on a trip little brat! I'll be joining you soon to train you as a real Saiyan warrior." Raditz explained as the pod began to lift off the ground. "It's no use in resisting. In a few moments the ship will pick up speed and if you destroy it in a fit of rage you will die with it!" Raditz yelled as the pod disappeared from sight. "Now I'll put the same coordinates in my ship so he doesn't wind up alone on that wretched planet. If he dies out there Vegeta will kill me as well for failure." Raditz said to himself.
After about a half an hour, Raditz realized he had company. Tien, Goku, and Piccolo landed in the now burned field. "Where is my son Raditz?" Goku questioned his brother.
Moving out of the crater his ship created, Raditz answered his brother, "He's gone Kakarot."
"If you hurt him I'll show you a world of pain!" Goku screamed back barely able to contain his rage.
"No I didn't kill him you fool. I sent him off to another planet where I will train him. That is after I exterminate all of you." Raditz boasted. "I see you brought some reinforcements too. The green man, and a human with three eyes? Is this a joke? I'll hardly break a sweat." Raditz arrogantly gloated.
"Don't take us lightly Raditz. Pride has lead to many of our enemies to fall." Tien said and began to focus his energy. Piccolo removed his cape and turban and also began to focus his power.
"Heh this is good. Three eyes has a power of seven hundred now. The green giant is an even eight hundred." Raditz thought to himself. "Kakarot how strong are you?" the evil brother inquired.
"I'll show you how powerful I am!" Goku screamed as he removed his blue shirt and raised his power level.
"What? Nine hundred? How could you be so powerful after living here your whole life?" Raditz said in disbelief.
The three warriors of Earth rushed Raditz at once, giving him little chance to power up. Tien launched a ki blast at Raditz who dodged the attack and retaliated with a swift chop with his right hand that caused the three eyed warrior to crash to the ground. Goku and Piccolo tried rushing the villain together but Raditz hurled two purple ki waves at the warriors. Piccolo and Goku had to use every bit of speed they possessed to narrowly dodge the incoming blasts. The Saiyan's attack caused a face of a mountain to explode in a blizzard of falling rock and gravel that covered the far off landscape.
"Damn he's strong Goku." Piccolo said trying to regain his composure.
"Yeah, by far the strongest person we have ever faced." Goku answered back.
"I've been holding back on you pathetic pieces of trash. I'll unleash my real power now." A confident Raditz boasted.
The long haired warrior began focusing his ki so intensely, the ground began to give underneath his brown boots. Before long, Raditz was surrounded by a purple aura that shocked the other fighters. Using his full power now, Raditz phased behind Goku and Piccolo and unleashed a powerful kick that sent both warriors flying many yards away. He began to laugh maniacally as he scooped Tien off the ground and lifted him into the air by his head. Raditz extended his left arm and began charging an energy wave.
"Time to end this pathetic excuse for a fight!" Raditz screamed as he launched the ki wave at Tien sending the three eyed warrior flying through the air. Tien screamed in agony as the attack Raditz used sent him soaring through the sky. Tien was able to force the blast off of him and prevented the attack from sending him into outer space. However, the warrior was extremely injured now and laid down on the dirt he crashed into to recover some strength.
"Who wants to be my next victim?" Raditz asked as he zoomed over towards Goku and Piccolo. Goku has to think of a plan quickly or he will never be able to save his son from his brother's clutches.
