After piccolo uses the special beam cannon on Goku and raditz, piccolo would tell raditz that they would bring Goku back with the dragon balls and then raditz would say that his two comrades who are superior to him heard this and would be on they're way to avenge him, and then raditz cuts his scouter off. While piccolo is telling raditz this, Goku eats a senzu bean and gets healed up. He walks over to raditz and tells him that if he fights and trains with Goku that he would spare his life. Raditz agrees and Goku gives him a senzu. Goku would ask piccolo if he wanted to train with them and piccolo would agree. So they go off and train for a year with the Z-warriors. On the day of the saiyans arrival this is they're power levels,

Vegeta: 12,000
Maximum: 24,000
Nappa: 4,500
Maximum: 8,000
Goku : 11,000
Kaioken (self-taught): 18,500
Gohan: 3,600
Angry: 20,000
Piccolo: 7,500
Maximum: 8,000
Raditz: 10,750
Maximum: 11,000

         Vegeta tells nappa that he can go first so he scans for the weakest power level and sees that gohan is the weakest. So nappa fires a gigantic energy cannon at gohan and nearly kills him. Gohan gets really mad and fires a super kamehameha. Nappa dodges the attack but his arm gets blown off. Nappa then gets enraged and attacks gohan full on. As he is about to finish him off with a Ki wave, piccolo jumps in front of it and saves Gohans life. Gohan gathers all his energy into a super special beam cannon and it hits nappa dead in the chest killing him instantly. Vegeta then says its his turn to fight so he immediately attacks gohan and blows him up with a Galick gun. Goku sees this and gets so angry that his power level shoots up to 50,000 and he hits vegeta with every technique he has. Vegeta then transforms into a great ape and attacks Goku and raditz. He begins to crush Goku and raditz until krillin arrives and uses destructo disc to cut vegeta's tail off. Goku and raditz shoot off a joint-kamehameha and nearly kill Vegeta . Since Vegeta realizes that he's lost he calls his ship to leave. Raditz tells Goku that they have to kill him or he's gonna cause more trouble. Goku says to let him go because he wants to fight him again someday without any help. While oku and raditz are in the hospital from they're injuries from the fight, bulma and krillin decide to go to namek to wish back everyone who was killed in the fight. When they get there they find out that frieza and Vegeta are also looking for the dragon balls so they radio back to earth and tell Goku of these troubles. Goku and raditz eventually heal up so they can help fight them and wish back they're friends. So Goku gets dr. Briefs to make them a ship with gravity training. Goku and raditz train with each other in the month that it takes to get to namek. Meanwhile on namek, Vegeta and krillin have been working together to gather the dragon balls so frieza can't use them. Vegeta agrees to let krillin use a wish to bring everyone back to life as long he lets him have the other two wishes. Frieza then calls in the ginyu force I take care of them. The battle starts and Vegeta is fighting against recoome and getting smacked around with no effort. Krillin has already gotten his neck broken by burter. Goku and raditz arrive and these are the power levels after training,

Goku : 310,000
Kaioken X50: 700,000
Raditz: 265,000
Kaioken X35: 575,000
Vegeta : 100,000
Battle damaged: 45,000

         Goku and raditz annihilate the ginyu force with no trouble at all and the heal Vegeta and krillin. Since Vegeta and krillin have already gathered 6 dragon balls, Goku decides to go steal the last one from frieza. So he's flys into the ship while (frieza is out looking for the dragon balls) and takes it. They soon summon shenron and ask him to bring back all the people killed by frieza and his men. Then as Vegeta is about to ask his wish, elder guru dies and so does the dragon. Frieza then shows up as angry as ever and attacks Goku. They fight and it seems that Goku is much stronger until frieza transforms into his 2nd state. That's when raditz jumps in and they try to attack frieza together. They get the upper hand until frieza gets so mad that he skips his 3rd state and goes straight to 4th. Frieza then grabs krillin and blows him up. Goku then gets so angry that he transforms into super saiyan. He begins to dominate frieza and begins to nearly kill him, until frieza goes I to full power and begins to be able to fight on an even level with Goku. After awhile Goku decides to finish things with a Super Saiyan Kaioken Kamehameha. The blast obliterates frieza but then hits the planet and it begins to explode. Goku , raditz and Vegeta then take Frieza's space ship and punch in random coordinates. They exit the atmosphere just as the planet blows up and then fly towards whatever planet they typed in. Meanwhile on earth, with piccolo ressurected they use the dragon balls to wish back krillin and the namekians a new home planet. 1 year and a half later, massive power levels are felt coming towards earth. Krillin says that it feels like frieza but only a lot stronger. So the Z-warriors meet up at where the aliens at ever to land. They are about to attack when a strange kid shows up and challenges the man who steps out the ship. The aliens name is cooler, brother of frieza. The mysterious boy says that Goku is not the only one who can go super saiyan. So the boy powers up and begins to fight cooler. The super saiyan is easily beating up cooler so he decides to go ahead and end it. He kills cooler and then tells everyone that goku, raditz and Vegeta are about to land. So Goku, raditz and Vegeta land when the mysterious boy tells Goku who he is and then warns him of a threat 3 years from now. He gives Goku an antidote to a heart disease that he will catch a little later. Goku then tells everyone of the android threat in 3 years and that they should all train as hard as possible. So Goku , raditz, gohan and Vegeta all train under an intense gravity routine of 550X normal earth gravity. After three years the power levels are,

Goku: 15 million
Super Saiyan: 250 million
Raditz: 12 million 
Super Saiyan: 230 million
Vegeta : 14 million 
Super Saiyan: 245 million
Piccolo: 8 million
Gohan: 5 million
Krillin and everyone else are around 900,000 to 1 million

         The Z-warriors find the androids in south city and tell them to follow them to a suitable fighting place. When they get there Goku and android 19 begin to fight. Goku is clearly dominating the fight and then fires a kamehameha. The attack hits the android dead on and immediately kills him. When android 20 sees this he immediately retreats back to his lab. As the Z-warriors are looking for him, android 20 activates #16, #17, and #18. Then trunks arrives and asks where are the androids. Goku tells him that they killed one and the other ran off. When trunks asks them to describe the androids, they're description is completely different from the androids in trunks' time. So they go off to find the androids, who then appear to them and ask to fight Goku . Goku quickly obliges and they begin to fight. While goku and #16 are fighting, Vegeta fights #18, and raditz fights #17. #16 is about to kill Goku when gohan steps in and knocks his arm off. Piccolo joins in as well and distracts #16 while gohan is charging a devastating attack. He fires it and completely obliterates #16. While this is occurring #18 and 17 have paired up and are beating Vegeta and raditz senseless. Then a strange power comes flying to the battle scene. The fighting stops and the new foe announces himself as cell, and that he's here to become a perfect warrior by absorbing 17 and 18. Since everyone is weak by fighting cell easily manages to absorb the three androids. Cell becomes super perfect and invites everyone to attack him with everything they've got. Goku, vegeta, raditz, gohan and piccolo all attack cell with all the power they have. Cell takes the combined blast dead on and takes no damage at all. Cell decides that since he wants a challenge then he will give everyone 2 weeks to train. As everyone is flying away goku suggest that they try the hyperbolic time chamber where you can fit years of training into only a couple of days. Goku goes to the lookout and asks kami if he can create 2 hyperbolic time chambers. Kami agrees and creates another time chamber, he even upgrades it to where 4 can go in at a time. So goku, gohan and piccolo go in one chamber while vegeta, trunks and raditz go in a different chamber. After 2 days on earth and 2 years in the chambers, goku and everyone else emerge. Power level:

Goku: 50 million
SS: 370 million
SS2: 600 million
Gohan: 20 million
SS: 275 million
Raditz: 40 million
SS: 390million
Vegeta: 50 million
SS: 370 million
SS2: 595 million 
Trunks: around Gohans level
Piccolo: 45 million 
Cell: 950 million

Everyone else is still about the same.                   They all fly off to battle cell. When they get there trunks wins a drawing to fight cell first. Trunks powers up to his limit and attacks cell with everything he's got and is effortlessly flicked aside by cell. Next up is piccolo. Piccolo gives cell a little bit of a harder time then trunks did but is still ultimately outclassed. Then raditz decides to skip everyone else and fight cell first. So raditz begins to fight cell and actually lands a few lucky attacks. But then raditz charges up a new attack that blows cell away. Everyone is excited that raditz beat cell but vegeta and goku know better. Cell then regenerates and kills raditz, and piccolo with a scatter shot type attack. Goku gets enraged and powers up to super saiyan 2. He and cell start fighting with goku starting to overpower him because of the blast that cell took from raditz. Goku then delivers a powerful punch to the stomach. Cell decides to fight at full power and then begins to beat the crap out of goku. Goku is half dead before gohan intervenes and attacks  cell while someone gives him a senzu bean. Gohan is holding his own until cell fires a gigantic kamehameha wave and nearly kills him. Since they gave goku the last senzu bean gohan is just laying on the ground near death. Goku gets a small power up from the senzu bean and attacks cell. From all the fighting cell is a great deal weaker but still able to fight with goku on an almost even level. While goku and cell are fighting, vegeta and trunks decide to use a combined final flash on cell. So they charge up their energy and wait for the right moment to kill cell. They find an opportunity and fire, but right when they fire cell dodges the attack and it hits goku full on, completely obliterating him. Gohan sees this and gets extremely angry and attacks cell but to no avail. Cell breaks Gohans arm and puts him out of the fight once more. Vegeta who gets angered by his actions attacks cell at full power which is a little bit stronger than cell is at that point. Vegeta begins to wipe the floor with him and is about to finish him off when gohan suddenly transforms into super saiyan 2 and obliterates cell with a kamehameha. Vegeta and gohan then travel to namek to find a new guardian for earth who can recreate the dragon balls. They find dende who agrees to be the guardian and they fly back to earth. After they've wished everyone back, goku and raditz decide to stay in the other world and train. Everyone then goes their separate ways. 

    7 years later...
Chichi has a son named goten that was made before goku died. For 7 years vegeta and gohan have been training. Gohan trains with his little brother goten and vegeta trains with kid trunks. Gohan then decides to go to school where he meets videl who persuades him to enter the world martial arts tournament. Goku then telepathically tells gohan that he and raditz get one day on earth. So gohan tells everyone and they all begin lite training. After they meet up at the tournament power levels are
Goku: 200 million
SS: 550 million
SS2: 800 million
SS3: 1.3 billion
Raditz: 175 million
SS: 400 million
SS2: 745 million
Gohan: 80 million
SS: 250 million
SS2: 660 million
Goten: 30 million
SS: 270 million
Vegeta: 200 million
SS: 575 million
SS2: 800 million
Trunks: 30 million
SS: 280 million
Everyone else is sill the same from cell saga.

     They all enter the tournament and watch the kids division first. Goten and trunks both make it to the final round. They start off as super saiyan and begin a very intense fight. They're blow for blow until goten fires a small spirit bomb technique taught to him by gohan. Trunks doesn't expect his attack and takes it dead on. The blast is so powerful that it weakens him out of super saiyan state. Goten then reverts to normal as well, so that it can be fair. They begin to get bored fighting in such a small ring so they fly off to the mountains to fight. The announcer disqualifies both of them and the adult division soon starts. The group then meet the supreme Kai who tells them that he needs they're help after the tournament. The preliminaries begin and the group qualifies along with Hercule and might man (goten and trunks in disguise). The first match begins with spopovich vs videl (spopovich is an evil minion of babidi which is whom the supreme Kai needs help with). Spopovich is beginning to kill videl in which gohan gets enraged and attacks him. Spopovich gets him in a headlock while his comrade yamu sucks Gohans energy to give it to babidi. They then fly off to babidi. Supreme Kai tells the goku, vegeta, raditz and piccolo to follow him while gohan gets healed. Supreme Kai then tells them the story of how babidi's father created an incredibly powerful monster named majin buu. He said that babidi is in earth trying to revive majin buu which is why they took Gohans energy. They find babidi's ship and are then attacked by his henchman dabura. Dabura then turns piccolo to stone and kills kibito Kai (supreme Kai's assistant). Dabura then prompts goku and the other to follow him into the ship if they want a challenge. On the first floor babidi sends out broly who he brought back to life with his powerful magic. Babidi also revived cell, frieza and cooler. Goku takes on broly, vegeta takes on cell, raditz fights cooler and gohan fights frieza. With all these fights majin buu's full energy is restored to his kid buu state. The saiyans manage to kill babidi's warriors but are then faced with the kid buu opponent. 

Kid Buu: 2.5 billion. Gohan and vegeta attack him first in their full power. They manage to at least give goku and raditz a chance to fuse. They then fuse into super saiyan 2 Radku. By using this much power goku and raditz' time on earth is cut to 1 hour. Radku and kid buu then begin to fight. Radku is much more powerful than buu but because buu can regenerate it seems nothing can stop him. Radku's fusion runs out. Kid buy then begins a rampage which almost kills vegeta and gohan. They all manage to escape to Kami's lookout where they find that goten and trunks sensed the trouble and brought all of their friends and family so that they wouldn't be exterminated with the people of earth. Goku and raditz begin to try and teach gohan, vegeta and goten and trunks how to fuse so that maybe they can stop majin buu. When they're time on earth is up goku and raditz give the fusion teaching responsibility to piccolo. Goku and raditz decide to leave with supreme Kai to his planet so they can try and pull the Z-sword from the ground. Goku manages to get the sword out and begins to train with it. When raditz blocks a powerful hit from the sword it breaks and old Kai is brought out of the sword in which he was sealed. The old Kai asks the supreme Kai why there are mortals on the sacred planets and supreme Kai tells him the story of majin buu. Old Kai tells him of porterra fusion and then gives the porterra earrings to goku and raditz. While this is going on kid buu has destroyed most of earth by looking for strong warriors. Vegeta and gohan have mastered fusion and go to fight kid buu. Vehan and kid buu are almost even. It seems like kid buu is about to finish Vehan when goku and raditz appear fused as Goditz right time kid buu absorbs Vehan. Kid buu almost doubles his power and decides to attack Goditz. Kid buu dominates and decides to also absorb Goditz. He manages to do it but sense the porterra fusion is stronger than he doesn't get completely absorbed and then goes off to find gohan and vegeta. They find them and cut them from buu's control. They manage to escape from buu's body. Buu gets extremely angry and decides to blow up the planet. So goku uses instant transmission and teleports all the Z-warriors to planet of the Kai's. goku, vegeta and raditz decide to fight buu alone so they raise they're power as high as possible to attract buu to the planet. Soon buu teleports to the planet and they begin to fight. They power up to they're maximum and begin to fight majin buu. Goku decides to try a super spirit bomb and asks for vegeta and raditz to hold buu off for as long as possible. Goku then begins to gather energy from all across the galaxy. He launches the spirit bomb and it's catches buu by surprise. It's finally kills majin buu and the threat is over. 10 years later power levels are,

After pilaf uses the black star dragon balls for eternal life, piccolo tells them that if they get them back within a year then the earth will blow up. So goku goes to find the dragon balls that were spread across the galaxy. He finds them with ease up until he makes to the metal planet. There general rildo has the dragon ball. Goku decides to fight him for it. Goku powers up to super saiyan and begins to fight general rildo. Goku is getting pounded so he powers up to super saiyan 2. He begins to wear general rildo down but is still being beaten. Goku transforms to super saiyan 3 and them finally begins to beat general rildo. But since general rildo is made of metal and apart of the planet, then he continues to regenerate. General rildo eventually traps goku into metal and sends him off to dr myuu. When he gets there dr myuu then re-animates goku so that baby could take control of him. But goku recovers faster than expected and he kills dr myuu. Goku then gets in his ship and flies off for the next dragon ball. Baby then takes a ship directly to earth so that he could become stronger and get revenge on the saiyans. By the time goku gets to earth everyone is under baby's control. So goku drops off the dragon balls to dende and goes home. He notices that everyone is acting weird. He senses that vegeta is flying towards him and goku goes outside preparing for a fight. So baby arrives and tells him about his plan for revenge on the saiyans. They begin fighting and goku is getting completely defeated. They fight on into the night and baby delivers the final blow. As goku is laying there ready to die, he gazes at the moon. During the fighting, his tail actually grew back so as he looks at the moon, he transforms into a golden oozoro and rampages until he comes to his senses and finally transforms into a super saiyan 4. 
Goku at super saiyan 4: 8 billion. 

Goku then begins to dominate baby vegeta. As he is about to deliver a final blow, baby leaves vegeta's body and tries to fly away in a space ship but goku fires a kamehameha and blows baby into the sun. They begin to distribute the holy water to rid everyone of baby's evil power.

      Goku and his family are eating dinner when they hear a knock at the door. Trunks stumbles in half beaten to death and is mumbling "android 17". They ask him who did this and he says android 17 randomly attacked him as he was flying over. He says that there wasn't something right with him. Like there was something controlling him. Then a massive hole opens in the sky and a bunch of powerful foes begin to fly out of it. Goku feels an evil Ki coming from the hole so he flies in it to see what's causing all of this. Back on earth broly, super saiyan nappa, frieza, cooler, king cold, cooler and many other foes from Goku's past appear and begin to wreak havoc. While the Z warriors battle these foes vegeta goes off to find #17. By the time he gets there the 2 android 17's have fused to become super 17. Vegeta turns super saiyan 4 and starts to fight him. At some point it is believed to be even until 17 kicks vegeta unconscious. By this time goku has made it out of the hole and found 17. So he powers up and begins to fight him. 17 is winning and goku begins to think of a strategic way of beating him. Goku then uses a destructo disc to cut off android 17's arms and legs. He achieves this and then fires a gigantic kamehameha x10. Goten and trunks begin to gather the dragon balls so that they can wish back everyone who was killed in the chaos. When they do this, the shadow dragons are released and then begin to create even more chaos. Goku and vegeta spread out to go and combat the shadow dragons. Goku eventually comes across syn shenron. Goku then begins to fight Syn and isn't doing to bad. Syn then decides to absorb the dragon balls to go to full power. He absorbs them and then begins to smash Goku around effortlessly. Vegeta eventually arrives at the battle scene and tells goku that they need to fuse in order to beat omega shenron. They do this and become gogeta. They begin to completely dominate omega shenron. Then as gogeta is about to finish him off, the fusion splits. Because the fusion used so much power, goku and vegeta revert to normal and omega decides to finish them off. He charges the negative energy sphere and releases it. Goku takes the blast full on and is at the bottom of a deep crater. Vegeta becomes extremely angry that omega killed goku so he channels all his power into one punch and omega takes it directly in the face. Omega simply shrugs this off and kicks vegeta to Goku's crater and tells him that he will put him in the same grave as goku. Vegeta then says it isn't over yet and passes out. Right after that goku slowly begins to rise out of the crater holding a universal spirit bomb. Goku tells omega that this is his ultimate punishment for all the pain and suffering that he's caused. Omega then begins to panic and tries to kill goku with ki blast. But goku merely absorbs these blast and then finally finishes the spirit bomb. He fires it at omega and completely annihilates him. Without even being called good shenron appears and revives goku. He tells goku that it's time to go and that he can say his goodbyes. Vegeta then asks goku if he's going off to train. Goku simply says "shh" and then falls asleep on the dragons back as he flies away.

   100 years later..
