The Majin Boo Saga

Seven years have passed since the Cell saga. Gohan starts attending Orange Star High School in Satan City (yes, they named the city after Mr. Satan). There he meets Mr. Satan's daughter, Videl. She is a crime fighter and is always there when something bad happens in Satan City. Gohan had gone to Satan City a couple before he started school, and each time he went he had to save the city from some criminals. Instead of having everyone find out who he was he would turn into a super saiyan and so he got the name of "The Golden Warrior". Videl arrives to the crime scene late and a man that saw the whole thing tells Videl that the person who saved the city was a young man with blonde hair, the school emblem, white shirt, black vest, and orange pants. So Videl goes to school and asks the guys with blonde hair if it was them. Then she accuses Gohan that it is him because he was wearing what the man had described, but he reminds her that he doesn't have blonde hair. She then tells him that she was wrong about him and that she didn't mean to accuse him, but she still has a suspicion because she remembers seeing some men that were able to turn their hair blonde during the Cell tournament from some of her dad's old tapes, but her dad had told her it was just a dumb trick and so she forgets the idea.
Since Gohan finds out that she is going to discover him he goes to Bulma to ask her to make him something. She does and he is now the Great Saiyaman. In his disguise he saves a lot of people and now Videl wants to find out who the Great Saiyaman is because he saves her two times. She finally does find out Gohan's secret, by a scar that Gohan had on his face, and begs him to teach her how to fly. She also makes Gohan join the Tenkaichi Budoukai so that they can fight against each other in the final, and so he finally agrees. About this time Gohan goes to Capsule Corp and asks Bulma to make him something else for his head so that he will be able to fight in the tournament, because the helmet he had now was not allowed. When Vegeta hears that Gohan was joining the tournament he tells Gohan that he too will enter because he wanted to see if he was now stronger than Gohan. A voice comes out of nowhere and says that he too is joining the tournament. It's Goku! Goku tells them that he will be granted one day to fight in the tournament and so Gohan goes and tells the other Z warriors.
Kuririn was living with Kame-Sennin along with his wife C-18 and his daughter Marron. When C-18 finds out that the tournament winner would recieve one million zeni, she insists on joining and starts training right away. Piccolo is living with Dende at his Palace along with Mr. Popo and says that he too will join. During the meantime, Goku starts to train in heaven. Gohan goes home and tells his mom and we find out that Chi-Chi has a second son named Goten that was born a couple of months after the Cell tournament. Gohan tells his mother that Goku will be coming and she gets so happy and is even happier because she will win a lot of money because she says that Goku and Gohan are sure to win first and second place. She allows Gohan to miss school to train and so Gohan begins his training. Goten tags along and when Gohan asks him to help him he shows Gohan that he too can turn Super Saiya-Jin. Gohan is so surprised and happy. He didn't think that Goten could turn Super Saiya-Jin at such an early age. So now Gohan trains with Goten, but there is a problem. Goten does not know how to fly. Being a nice brother, Gohan tells Goten that he will teach him to fly. At this moment, Videl comes in and reminds Gohan that he promised her that he would teach her to fly. So the next day they start their flying lessons. Goten gets it right away and Videl learns a little while afterwards. At the same time Vegeta too trains in the time room with Trunks. He was training under a lot of gravity and it was too much for Trunks. Vegeta asks him to leave because he would only get hurt, but then Trunks turns Super Saiya-Jin and starts running all over the place. Vegeta is very surprised and finds out that Goten too can turn Super Saiya-Jin.
The day of the tournmanent finally arrives, and of course, so does Goku. The children's tournament begins first. Goten gets runner-up and Trunks wins. Being the winner, Trunks gets to fight against Mr. Satan. With one simple punch, Trunks wins, and Mr. Satan says he "let" Trunks win. When the tournament for the adults is about to begin, two strange men appear before Goku, and both of them are finalists in the tournament. The first fight is between Kuririn and Punter, and of course Kuririn wins. The next fight is between Piccolo and Kaioh-Shin, and for some odd reason, Piccolo refuses to fight him because of the major difference in "dimensions". After the fight Piccolo asks Kaioh-Shin if he is Dai-Kaioh-Sama, but Kaioh-Shin tells Piccolo that he is not, that he is the Supreme Kaioh-Sama, which is the God that the 4 Kaioh-Sama and the Dai-Kaioh-Sama worship.At this Piccolo is very astonished, but promises not to tell anyone. The next fight is between Videl and Spopovich, Spopovich wins. It's Gohan's turn to fight next and it is against Kibito. Kibito asks him if he would turn Super Saiya-Jin for him, and so he does. This moment, two men with "M"s on their foreheads, named Spopovich and Yamu, steal Gohan's energy. The two run away and head toward a space ship. While Gohan is still unconscious, Kaioh-Shin follows the two men and then so does Vegeta, Goku, Kuririn, and Piccolo (just a few moments before, Piccolo told them who Kaioh-Shin was). Before they leave, Kibito reassures Goku that he will heal Gohan, and so Goku leaves Gohan to Kibito. Kibito does exactly what he said, he gives Gohan's energy back, even a little more than what he had before. While Goku and the others are following Kaioh-Shin, Kaioh-Shin tells them about the story of Majin Boo and Babidi. How Babidi's father, Bibidi, had killed the other Kaioh-Shins. How Bibidi was killed and how Majin Boo got trapped in an egg. After Gohan gets his powers back, him, Videl, and Kibito try to catch up with the others. While at the same time Kibito is telling them the same story. Since most of the participants left, and the tournament must go on, some fights continue and we get to the finals. It is between C-18 and Mighty Mask (which is Goten and Trunks in disguise), to see who gets to fight the almighty Mr. Satan. C-18 figures out who Mighty Mask is and so Mighty Mask is disqualified. C-18 is up to fight Mr. Satan. Mr. Satan is very scared of her because he saw the fight against Mighty Mask and knew what she could do. So C-18 takes advantage and tells him that she will let him win if he gives her 2 million zeni (remember, the prize was one million) and so Mr. Satan accepts and he wins the tournament.At the same time, Goku and the rest enter the ship, while Piccolo and Krillin stay outside because they were turned into stone by Dabura's spit. As they enter different stages they have to pass some obstacles, like fighting some bad guys, but of course the warriors win all of them. But then it's Gohan's turn to fight (he had not trained at all) and he is up to fight Dabura (Babidi's main guy). The fight seems pretty even and is barely starting. Dabura stops fighting and reports to Babidi. He tells him that he has a plan. Since he had felt that Vegeta was evil (he kept screaming at Gohan and Goku), he wanted for him to be on their side. And so Babidi posses Vegeta and he becomes Majin Vegeta (with an "M" on his forehead).All Majin Vegeta wants to do is fight against Kakaroto (Goku). They are transported onto the tournament (the final battle had just finished) and Vegeta blows up 2 sections of it, killing a lot of innocent by standers. This upsets Goku very much and finally agrees to fight him. In this conversation with Vegeta, Goku discovers that he let himself be possed by Babidi on purpose, because this was the only way to get Goku to fight against him because he (Goku) had only one day of life on Earth. In order for no more people to be killed, they are transported to another place where there are no people and so the fight begins there. While Gohan and Kaioh-Shin enter Babidi's ship. The intense fighting between Vegeta and Goku gives Majin Boo enough energy to be revived.So Boo finally wakes up and now Vegeta finally realizes good always triumphs over evil and self destructs in hope to kill Boo. Goku then heads to battle against Boo, Goku turns SSJ2, then SSJ3 but he still can't defeat Boo. Gohan heads to the Kaioh-Shin's planet for training. Later, Boo kills Babidi, and even become friend with Mr. Satan, but then Mr. Satan is nearly killed by a man, so Boo becomes very angry and smoke is coming out of his body, this smoke becomes Evil Boo, and Evil Boo absorb the now Good Boo, to become Super Boo. Before Goku's time is up on Earth he teaches Goten and Trunks the fusion technique, then they get trained by Piccolo so they can be strong enougth to beat Super Boo.Soon after Goten and Trunks fuse to become Gotenks, later Gotenks turns SSJ1 and SSJ3 in the room of time and spirit. Super Boo comes to Dende’s Palace. Gotenks is nearly defeating Super Boo, but the fusion stops, but Gohan comes, after his training at Kaioh-Shin Kai (Roh-Kaioh-Shin awakened his hidden powers, so he doesn’t have to turn SSJ anymore) Gohan fights Boo, and he’s a lot stronger, so Boo use a trick and hide during about one hour, then he appears again and ask Goten and Trunks to fuse again, the fell in the Trick and Boo absorb Gotenks and Piccolo, So, Gohan isn’t as strong as Boo any more. Roh-Kaioh-Shin sacrifices his life so Goku can live. Goku, now alive, teleports to the battle. Soon after Enma Daioh grants Vegeta one day on earth to fight Boo. When Goku arrives to the scene he tells Gohan to fuse with him, Goku then throws a fusion earring at Gohan. Gohan drops the earring and Boo absorbs Gohan.Then Vegeta comes to the scene, Vegeta fuses with Goku to become Vegetto. Vegetto defeats Boo, but lets himself get absorbed to rescue their friends (this wears the fusion off). They rescue Goten, Gohan, Trunks, and Piccolo through Boo's pores. All of the energy that Boo has taken, restores him back to his normal form, then Boo destroys the Earth. Kaioh-Shin teleports to help Goku teleport Vegeta, Mr. Satan and Dende to Kaioh-Shin Kai. But Trunks, Goten and Piccolo die when the earth explode. Boo survived the explosion of the earth and comes to Kaioh-Shin Kai, sensing Goku and Vegeta’s energy. Goku and Boo start to fight, Goku starts to get beaten up badly. Vegeta jumps into the battle so Goku can create a Genki-Dama. The Namek DragonBalls are gathered to wish back the Earth and to wish back everyone killed by Boo. The third wish is stored for later use. Goku ask the now alive earthlings to give their energy to kill Boo, but most of them (exept Goku’s friends) don’t agree to give their energy till Mr. Satan order them to raise their hands.(He’s still on Kaioh-Shin Kai too!!).The Genki-Dami is ready, Goku throws it and Boo pushes it back. Vegeta tells Dende to wish all of Goku's strength back. Now with all his strength restored, Goku throws back the Genki-Dama at Boo. Boo can't counter so he is killed. Just before he dies, Goku ask Boo to become good and to come to fight with him. Ten years after the battle aganist Boo, Boo is reincarnated into an evil cleansed form called Oob. Goku decides to train him since he has great potential. Gohan and Videl get married and have a daughter named Pan. This is the end of DragonBall Z.
