What if Raditz turned good

Brother fight

The Sayins - a proud race of warriors who were rough and tough race. They were one of the most feared race in the universe. Most intelligent life would call them just savage monkeys because of their monkey tails which were their weak points. But the villainous King Cold -  part of the frost demon race took  over and eventually gave it to his son Frizza who becoming a dictator. Later a [ freak asteroid] hit planet Vegeta wiping out 99% of all Sayins. There were only 4 Sayins  left Prince Vageta the 4th, Nappa, Kakarot who was sent off world by his fathers gut feeling, and Ratiz the older brother of Kakarot who with Vegeta and Nappa lived under the boot of Lord Frizza. For his whole life, Ratiz  was considered weak by the two other survivors. He was with the others only because he had a power level of 1500 which is ridiculously strong for a human. But for a Sayin it's really weak I mean your average Sayin was 2000 or 3000 and it didn't help he was around 2 elites.  Nappa was at 6000 and Vegeta was at 9033.

As the Sayins had just conquered over a planet for Lord Frizza,  Vegeta then said something " you know I'm sick of just 3 Sayins being around, are you sure their were no others who escaped the asteroid". " Nope sorry Vageta but you know what we could get" says Nappa " no not the dragon thing again" says Vegeta ." Please Vegeta " says Nappa crying like a baby ." Hey my mom said she sent my brother kakarot off world before the asteroid hit" says ratiz ." Well if you look at that weakling ratiz is actually worth something" says vegeta. After they finished off the planet they got in Their space pods and left when they were in the zone where they could get to earth the quickest. ratiz began to wonder what his brother has been up to they must have just sent him to that 'eearth'   ( I spelled it like that because they think it's spelt like that) to sell it. 

Earth 

As a farmer is picking out his food for his family gathering, he sees ratiz ship enter the atmosphere and crash-land in the field and get out of the pod. As the farmer goes to check his carrot patch he gets his gun out only to see ratiz levitate out of the crater he made  " hmmm this planet has so much life kakarot must have failed, lucky his big brothers here" says ratiz. 

As the farmer cowers in fear he decides I'm not going to let this sonic the Hedgehog look alike boss him around " hey you" he says before pointing at ratiz with his gun " oh please your power level is only 5 I can easily defeat you" he says referring to how it was possible, while he was panicking, he uses his scouter to check his power level " I don't know what your talking about now get off my property or I'll shoot you" said the farmer as he fired his gun but ratiz caught the bullet flinging it at the man faster than the gun. He thought humans were stronger so he thought he knocked him out and didn't know he killed him " now to find that wimp" says ratiz flying off. Later  as he's flying he's sees another high power level and heads towards it . enter Piccolo one of the world strongest fighters in the world ,son of the demon king who he was named after. Once he had been defeated by the hero of earth and world champion goku he went out to the mountains nobody ever heard from him for 5 long years well until now. As piccolo was practicing his ki ( energy) he sees ratiz floating above him " oh your not kakarot" says ratiz " what's a namekin doing on this planet".  ratiz  thought piccolo should be on their own planet " who the hell are you how did you find me!?" Asked a confused and angry piccolo he didn't like people interrupting him during training " well I was wondering if you know anyone by the name of kakarot" asks ratiz " kak-who?" Responded piccolo not knowing who he was talking about  " oh so you don't we'll I'll answer your question from earlier this is a scouter it can show me  power levels" says ratiz "  why are you telling me this" asks piccolo " because I know you won't be alive to tell" says ratiz " SHING-FRIII- oh another power level must be him" says ratiz not using his attack   as he fly's off " hey" shouts piccalo flying behind him. 

Son goku is  the earths strongest fighters after going on many adventures with his friends to find the dragon balls 7 mystical orbs and when they are all brought together a dragon is summoned called sheinron who will grant you one wish with no side affects and then they scatter across the earth for one year before they can be used again. after defeating son of the demon king piccalo JR he married chi-chi daughter of the ox king though  when she asked him he thought she meant dinner. Goku was like that  though since he was raised by his grandad and grandad only in the forest  so that meant he didn't go to school and only started to learn about human things after meeting a girl named Bulma who was teenager looking to use the dragon balls to wish for a boyfriend but she didn't get a boyfriend  and instead got a fighter Yamcha. now after all the piccalo stuff was done and he won the 23rd world martial arts tournament he had a son named gohan named after his granddad. Then he was taking his son to see his friends krillain a short man who goku trained with. goku and the two were best friend since. master roshi was the man who trained goku and krillain in martial arts and bullma. since goku saw her last she had taken over her dads company capsule corp which can make cars , boats and even planes. 

kami house 

As Goku arrived at the home of master Roshi on the flying nimbus a  magic cloud he was given on his original quest for the dragon balls. Him  and his son  gohan make it down and greet all his old friends. Later after they all caught up after 5 years of not seeing each other krillain and goku sense something " holy black on a popo what is that" says goku talking about the genie  who helped train him. As they all look up to see ratiz in the air " found you" whispers ratiz as he drops to the ground. "Who the hell are you" asks goku sensing ratiz is strong " hmm well you did an awful job this planet is amazing,  you had  one job destroyed it and you failed kakarot" says ratiz " who"  asked goku as ratiz gave a puzzled look at goku but he then finally realised " you hit your head as a kid didn't you" said ratiz then master roshi stepped in saying how when goku s grandpa told him when goku was a baby he hit his head off some  rocks." And that's the story" said roshi  as goku friends had thought that explained's a-lot " anyway what do you want"  asks goku in a fighting stance. Ratiz then goes on to explain about the sayins and how their planet was destroyed and saying his belief that he was sent here to destroy it." And that's the story of our people and now we can destroy this planet and now we can sell it for profit" says ratiz " what I never sell earth" says goku as he charges at ratIz krillain doing the same but ratiz using his tail slaps krillain into Roshi house and needed goku in the stomach. Then he picks up gohan who crying his eyes out " now I want you to have 100 dead humans on this island by tomorrow or I'll kill you and I'll take your son with me" says ratiz  laughing but evil and he flys off " no" shout's goku as piccolo then appears " hey you see a sonic the hedgehog look alike fly through here" says piccolo after goku explains who ratiz is too piccolo the two begrudgingly work together goku to find his son and piccolo I mean he thinks only one man can rule the world.
