Chapter 1

"Dad, are you sure this is the right way? I can't see an island anywhere" said a young boy wearing a green hat, white shirt and green tunic with green pants. Gohan son of Son Goku the renowned martial artist who had won the last 'World Strongest Under Heaven' tournament, was on a trip to see his father's friends.

"Don't worry Gohan, Nimbus knows the way there better than even those talking things in your grandpa's fancy cars, it won't be too long now." As if taking a cue from Goku, the little yellow cloud put in a burst of speed knocking Gohan into his father's lap.

Goku caught him by the shoulders and laughed. He looked around, the ocean was calm and blue, the suns' rays heating up his body and the cloud's protective aura allowed just the right amount of cool wind to keep the large man and his son just comfortable. Goku was excited, he'd last seen his friends when they visited during Chi-Chi's pregnancy. Not only did he want to catch up with how they have been doing but he was also excited to see how strong they had become. It had been a long time since he sparred with someone and didn't have to hold back. Goku smiled, he couldn't think of a more perfect morning.

Outside of Earth's orbit a transparent blue vortex formed and a small spherical ship phased into existence. The ship's occupant opened his eyes, as the process to bring him out of slumber had already begun. The ship's computer signaled their approach to the destination.

The old farmer wasn't sure what to think of the situation. One moment he was in his truck going to inspect his crops and the next a sphere like ship blocked his path. Out of it came a very large man dressed in what looked like brown and black body armor that covered his torso, shoulders and thighs. As if his stature wasn't intimidating enough the stranger's long black hair was wild and unkempt, giving him the appearance of a predatory animal. Shotgun in hand the farmer got out of the truck.

The stranger looked at the farmer and the truck with almost a hint of surprise. Then he pressed the large eye piece device on the left side of his head. A faint beeping was heard. The stranger focused his eyes on him and some sort of writing appeared on the screen. "5. Pathetic." he heard the large man say. "5? Pathetic? Mister what are you talking about? This here is my property so unless your ship is broken I'd suggest you get on going. I don't want any trouble!" said the farmer nervously to the much larger man advancing on him. His words seemed to take the stranger by surprise. "So you can speak. How very unfortunate for you but I need to stretch after being stuck in the ship for so long" said the stranger as he raised his open palm in front of him. "What the heck are you talking about? Stop right there or I'll shoot" he points the shotgun at the large man's chest, "I said stop!" a loud bang is heard as the shotgun discharges in the other man's chest. The farmer drops the gun, shocked, his whole body tense. The stranger didn't have a single scratch, completely unharmed, in fact even smiling. A white aura enveloped the man's raised palm "Nice shot. My turn now!" he heard the stranger say before the white light engulfed him.

Piccolo snapped out of his meditative state. He felt it. A large power, nothing like he ever sensed before appeared and was approaching his location fast. "How can this be? Is it Son Goku?" Impossible, he saw him now. A large man with wild long black hair landed a few feet away from him. "Huh, you're not Kakarot! Tell me green man where is Kakarot and you will live for another day."

Piccolo was trembling, he could feel the overpowering aura of the man and it's bloodlust but the man's words angered him. He was being dismissed for whoever this Kakarot was. He doubted he would be able to overpower him but with a surprise attack he might be able to get an advantage. "I don't know who this Kakarot is but you're dealing with me now HAA!" Piccolo yelled as he blasted the man with an energy wave. He couldn't believe it, the man didn't move, didn't block, just stood there and took the full force of the blast and came out of it unscathed. "I see you want to play, but with a battle power of only 322 you won't last very long. Now let me show you my technique." Piccolo saw the man raise his hand up, energy gathering in his palm. He had to escape but his body wouldn't move, he was just trembling, frozen in place. A beeping sound interrupts. The man disperses the energy harmlessly and uses his hand to touch a few buttons on his head piece. For a few moments it looks as if the man was staring at empty space. He smiles. "That must be Kakarot!" he says and flies of.

Piccolo drops to his knees breathing heavily, sweat running down is face. He was safe for now. But why wasn't he able to move? Shock, fear, no, he was supposed to be the demon king of this planet he was supposed to strike fear in the hearts of others he was supposed to be the strongest. And then it dawned on him. Until this very moment he had never actually faced someone stronger than him. Son Goku had been of comparable strength and Son Goku's friends had been weaker, not by a lot, but still weaker. Rage surfaced again. Something had to be done about this intruder but the only one strong enough to be of any help was Goku and his pack of friends. He pondered for a moment formulating a plan, it was risky but if he played it right he might just kill two birds in one shot. With his mind made up he flew towards his target.

"So yea, last year, after the contractors were done and the house remodeled we moved back to the mountain. The city is nice and living at the palace with servants and all was great especially the food!" said Goku between bites. He was sitting on the patio outside with Bulma, Roshi, Oolong and Krillin. "But it was too restrictive I much prefer the mountain with its forest and rivers. Chi-Chi does insist that we either move back to the palace or the city in a couple of years. She wants Gohan to go to one of those fancy private schools."

"I guess he really won't follow in your footsteps, eh!" said Krillin as he looked at Gohan who was playing with Turtle on the sandy shore. "Well of course I'm going to show him some moves but you know it really depends up to him how far we take it. I'm not going to force him to" suddenly Goku stood up and put the chicken leg back on the table. He was looking in Gohan's direction only upwards into the sky, concern showing on his face.

"Umm, Goku, is something wrong?" asked Krillin bewildered by his friend. "Something is coming, someone strong and it doesn't feel too good." he responded. "The boy is right." added Master Roshi. "GOHAN, TURTLE! COME HERE NOW!" yelled Goku at his son. Gohan, having never heard his father speak in such a harsh tone before, quickly rushed to his side, Turtle behind him.

Moments later the large man with body armor and wild hair landed on the shore. "Kakarot! It must be you, you look just like father!" He said looking straight at Goku. "Huh? You must have me mistaken with someone else. I'm Son Goku." answered Goku. "Who are you anyway and what are you doing here?" Goku continued. "Kakarot what's the matter with you? I'm your brother Raditz!" said the stranger. Everyone looked confused, unsure what to say. As they took a closer look at Raditz he did seem to resemble Goku. Bulma broke the silence. "Goku , you never told us you had a brother."

"That's because I never knew myself." He said looking confused. "Look, if you are my brother prove it! Grandpa Gohan would have told me if I had a brother!" he said to the stranger.

"I am not proving anything to you. I'm the one asking questions and you will give me answers. As far as I can tell you are the strongest power on this planet. Why haven't you culled it and returned? And your motive better be broken ship otherwise you will find yourself in a world of pain never experienced before!" said Raditz angrily as his tail unfolded from his waist.

"Look Goku he's got a tail like you" pointed Bulma. "Hey yea you're right!" remarked Goku. "Of course I have a tail you fool all Sayan's have one, it is the pride and…wait a minute WHERE is your tail?". "Huh, oh yea it got cut off a long time ago." Replied Goku. "What have you done, you idiot the tail is a Sayan's greatest source of power without it you can't unleash the great ape transformation!" shouted Raditz not believing his eyes.

"Great Ape, Sayan, broken ship? I don't think I understand what you are talking about "And what do you mean culled the planet?" continued Goku.

"Culled as in killed the dominant species, considering you survived to adulthood and this planets low battle power you should have had ample time to get it done by now!" Raditz said getting more and more aggravated with each passing moment. "Where is your ship it should have fed you the appropriate instructions as you got older and it should have contacted the nearest base! Don't tell me you wrecked it? Come on we don't have much time!"

"Look I really have no idea what you are talking about!' said an even more confused Goku. "I think you have the wrong guy" said Krillin as he approached the large man "Goku has no ship and he would never take any innocent lives. Now I think you should get out of here before you find yourself into trouble"

"Krillin no!" shouted Goku but before Krillin could fully put up his defenses Raditz's tail connected propelling the martial artist straight through the Kame House walls. Goku immediately dropped into a fighting stance his energy surging through his body. The intruder's eyepiece started beeping, images flashing on its screen. "I like the fire in your eyes Kakarot, but your battle power is pathethic." He said looking at the screen "besides we don't have time for this, we need to find your ship and" before he could finish, Raditz was interrupted by a soft scared voice and a sight he hadn't seen in years, a small boy with a long brown tail that was slowly wrapping around his brother's leg.

Radditz stared in disbelief, it shouldn't have been possible, there were no Sayan females left, none that he knew of at least. "Daddy what's going on?" asked a scared Gohan. "Gohan stay back", Goku pushed his son behind him "Bulma, take Gohan in the house please, NOW!".

So it was his brother's son, it only made sense, Kakarot was the only Sayan on this planet and it was now obvious this planet's species was compatible with Sayans. This complicated things even more, so far all information about this planet had been wrong, technology level, language and now his brother had gone native with a child in tow. There were a few other species with which Sayans were compatible however halfbreeds were rarely accepted and the current situation was even more precarious. Regardless of the wrong information this planet had already come to the attention of the others. At best it would become a colony at worst the original plans will stand the planet will be cleared and traded. Raditz realized that only destruction is in the future of this place and he will have to make a choice to either stand with his estranged brother or die at the hands of the others.

Raditz knew even this planet couldn't possibly stand the onslaught that it was going to be facing so he had to act fast. He had to make his brother relinquish his ties to this place it was the only way he could save him and maybe the child. Raditza decided if he couldn't convince him then he would use force, his little brother would understand once the others came. "Kakarot !" Raditz's gaze shifted back to Goku "That child is yours, I can tell, a half breed, I will give you one day of this planet to kill and bring me the heads of 100 of this species inhabitants and pledge your allegiance to me and the sayan race. If you do that your life and the child's will be spared!"

"I told you I'm not doing that and I'm not going to let you hurt" before he could finish and put up a full defense Radtz's knee connected and sent him flying creating a second hole in the Kame house. Before anyone else could react Raditz turned to the now crying Gohan grabbed him by the tail and lifted the boy to eye level. With no previous training, the pain from being lifted by the tail caused Gohan to become unconscious. Raditz could see the boy had a passing resemblance to his father but just as himself the boy obviously took much more after the mother. He wondered who the mother was his gaze going to the blue hair female which was frozen in shock. There was a vague resemblance but he doubted it, either way it wouldn't matter if he couldn't get his brother to join him. " You !" he said to Bulma. "Tell my brother that I have his child, my offer stands, 100 kills and he and the child will be spared. I will return to this place in one day's time." Raditz said as he floated of the ground and launched himself in the direction of his ship.

It was Oolong's voice that snapped both Bulma and Roshi back to attention. " Guys! Krillin and Goku need help!" yelled Oolong from inside the house. No sooner as he finished his sentence Goku and Krillin's groans drew their attention. " Ah I think my arm is broken and head is still spinning" said Krillin as was helped up by Master Roshi.

Goku came too more alert, panting "He knocked the wind out of me, I think I blacked out for a moment, where is he ? Where did he go?" he asked Bulma as he exited the crumbling house.

"Goku…"

"Wait ! where is Gohan? GOHAN!?" yelled Goku, with desperation in his voice and sinking feeling in his chest. "Goku, that man Raditz, your brother, he took Gohan! He said you have to kill 100 humans before he returns tomorrow if you want Gohan to live!"

"He's not my Brother!" snapped Goku " Grandpa Gohan would have told me if I had a brother! And I have no Idea what he is talking about sayans and killing people, I am not doing that!"

"Goku, actually what he said might have some truth to it." Interrupted Master Roshi "Huh?..what do you mean ?" asked a surprised Goku, all eyes turned to Master Roshi " You see Goku, quite a few years before we met, your grandfather Gohan called me to tell me the most interesting tale. He had found a very peculiar boy with a tail, inside what he thought was a new air ship of some sort but upon closer inspection of the ship, it's advanced technology seating for 1 and due to absence of other ships or even bodies of who could be the parents, Gohan theorized that the boy might even be from outer space. I of course dismissed such nonsense at the time, having encountered many different humans and complicated situations in my life." said Roshi, looking around and being met with the stunned silence of the group. "So you've met Goku before he started training with you?" asked Oolong confused.

"Not exactly, I had never met him before that, Gohan only told me about him, actually the last time I saw Gohan alive was when we both went to sort out the situation in the Ox kingdom" said Roshi " And I think maybe just a bit over a year later of that call I received another call from him, telling me he had adopted the boy and named him Goku. He told me that the boy was unordinarily aggressive, combattative, that he had great strength for someone so young. He told me that he had started to train him, that fighting and physical effort were the only ways to calm him down, but that a few months during their training he didn't pay attention for a moment and the boy had fallen off the side of a cliff. Gohan thought Goku to be a goner but when he got to the bottom, there was Goku, smiling and happy, laughing at an angry bird trying to save the remnants of its new build nest out of Goku's wild hair." Continued Roshi. " He also said that after the fall Goku must have hit his head very hard, he had a huge lump on the back of the head, Gohan was scared but everything seemed fine, Goku's behavior had changed, he was able to pay more attention to Gohan but still had high energy as before and the aggressiveness turned more into childlike curiosity, except for when the moon was close to being full, it came back, it made him more feral more animal like, stronger as well. The most impressive and terrifying thing had happened on the full moon. He caught Goku looking at the full moon in the middle of the night, when the moon was closest. He said the boy was almost in a trance that his body had slowly started to change became more feral grew twice as big as the house became incredibly strong and aggressive he, became a giant ape. Gohan said it took him the whole night to keep the ape from destroying the surrounding forests. By day break Goku had calmed down and transformed back without recollection of the night before."

" He figured it was the moon that caused the transformation, so he asked.."

"He asked me to never look at the full moon or the bad monster will come and destroy the land again" interrupted Goku, a somber look on his face eyes staring at the ground " The monster that crushed my grandfather was me afterall, I had always wondered about the circumstances but I never truly wanted to believe it." Continued Goku. " Either way none of that matters now, I need to stop him , I need to get Gohan back!"

"Goku, you can't take him alone, when he hit me I felt his strength, he's a monster, we need to call in Yamcha and Tien, even then I don't know if we stand a chance" replied Krillin.

"You will never succeed, you are all too weak!" a deep voice interrupted from above.

"Piccolo!" exclaimed Roshi "What do you want? If it's a fight you want now is really not a good time!" Continued Goku, clenching his fists and raising his energy.

"I'm not here to fight, I'm here because we have the same problem. That alien that made off with your son is an obstacle standing in my way. I'm here to propose a deal, we set our differences aside for now and kill the intruder." He landed on the island, looking intently for Goku's reaction.

Goku looked at Piccolo not dropping his guard. "And how can I trust that you won't stab me in the back?"

"You can't. Don't get me wrong Goku it is my destiny to conquer earth and that creature stands in my way! Once he is disposed off I'm coming straight for you!" Piccolo paused to gauge Goku's expression. His eyes focused on Goku's. "Beside, I don't think you have a choice if you want to see your son again." He finished with the faintest smirk on his face.

Silence permeated the group for a moment and then Goku smiled and dropped his guard. "Alright it's a deal." The group starred in disbelief.

"Goku you're not serious right? This is the demon king we are talking about here!" asked Oolong. "Guys I don't have much time. Like Krillin said even if we get Yamcha and Tien we might not be enough. Piccolo is here right now and the more we wait the more damage Raditz can do, not to mention what he can do to Gohan." He finished his tone leaving no room for further questioning.

"Bulma, do you have the dragon radar with you?" he continued. "Huh? Yes I do why?" asked the still shocked Bulma. "Please can you get it for us? Goha has the 4 star dragonball with him, the radar will help us locate him quicker."

"Yes of course. I will go get it now" she said and went to her airship. "Krillin." He said turning to his friend. Goku could see his old rival wanting to come as well but even if Krillin could help in getting Gohan back, if things didn't go well at least he could be revived with the dragonballs, Krillin could not. "I know you want to come along but your broken hand would only slow us down and put both us and you in danger. I think it would be better if you and Master Roshi are able to get some senzu from Master Korin and contact Tien and Yamcha." Goku finished.

Krillin looked as if he wanted to protest but seeing Goku's concerned look he relented. "Alright Goku, but make sure you stay alive until we get the senzu." His gaze turned to Piccolo "And don't get tricked by him" he finished.

Bulma returned with the dragon radar. Goku grabbed it and called for Nimbus jumping on the little yellow cloud. "Hey Piccolo think you can keep up with the Nimbus!" Goku yelled as he blasted into the sky. "Heh! I'd be embarrassed if your little toy could beat me!" the demon king replied as he followed Goku.

The gang couldn't help but stare at the two as they flew off. Shocked and at a loss of words for the events that had just transpired. Goku was an alien, his space pirate brother was here trying kidnapping Gohan and trying to kill humans and of all the people to show up to help them it was their enemy the demon king Piccolo. Bulma was the first to snap out of it.

"So guys, what's the plan here? Yamcha I can probably eventually get a hold of by satellite phone but Tien? Nobody knows where he lives or how to contact him."

"I think Goku is right." Said Master Roshi. "Well partially at least. Krillin you can't fight in your condition. You and Bulma should take her airship and make your way to Korin's tower. Master Korin will help you contact Tien as well, he will find a way. Getting the senzu beans is your top priority, Goku will probably need them sooner than later." Krillin nodded his head in agreement. The old master turned to Oolong.

"Oolong, you and me will take your airship and we will follow Piccolo and Goku." Roshi said with determination. "What!? Your crazy old man! You saw what that freak did to Goku and Krillin, what can we possibly do to help them!" said Oolong freaking out. "Yes, I don't expect to be able to do much, but someone needs to watch Goku's back and make sure he stays alive, we can also try snatch Gohan while they are fighting." Said Roshi. "You know what old man that's not a terrible idea! We grab Gohan and run. It will make it easier for Goku to fight" finished Oolong.

The group made their ways to their air ships and wished each other good luck. "Oolong you will have to drive. Just follow the direction they were going, I can still sense them so I will point you in the right direction as necessary. I the mean time I need to concentrate." said the hermit. "Concentrate on what?" asked the shape shifting pig. "Like I said I don't plan on fighting but I should be prepared for it if necessary." Said Roshi as he plopped down, cross-legged in a meditative position. As he grabbed the controls Oolong turned his head and saw a thin white shimmering aura enveloping the old master wasting no more time he took off in the direction of Goku doing his best to ignore that queasy feeling in his stomach and hope that they will all come out alive.
