Majin-Buu Saga

The adult vision starts finally. Krillin wins his match easily. It was Piccolo and Kai-oh-shin (he is the god of all the Kaio-shins and Daio-shins.) Piccolo knows Kai-o-shin's identity and gives up without a fight. Now it's Videl's turn against Supopo Bitchi. Videl loses her match because Supopo Bitchi was possessed by Babi-dee (you'll find out who he is later, which made him stronger and tougher to beat.). Now it's Gohan and Kibit, but Kibit knows Gohan can turn into a Super Saiyajin. Gohan ends up doing it and gets his power stolen by Yamu and Supopo Bitchi. Then the two go to Babi-dee's ship. The Z fighters follow except Goten and Trunks because they snuck into the adult tournament as Mighty Mask. On the way, Kibit and Kai-o-shin explains how Majin Buu's egg was on earth when humans were able to walk on two feet. The creator, Bibi-dee was killed from Kai-o-shin and didn't realize he had a son Babi-dee. The fighters meet Babi-dee and the king of darkness, Dabura (was possessed by Babi-dee). Dabura easily kills Kibit, and spits at Piccolo and Krillin, turning them into stone. He taunts the rest of the fighters and they fly into Babi-dee's ship. The fighters had to win each floor level to get to Babi-dee. Vegeta very easily wins over Pui-Pui. Goku's turn and easily defeats Yakorn. #18, Mighty Mask (Trunks and Goten), Jewel, Kyler, and Mr. Satan were the only fighters in the tournamnet and they have a battle royal. #18 and Mighty Mask easily defeat Jewel and Kyler, and then they both fight, ignoring Mr. Satan. #18 finds out he Mighty mask is Trunks and Goten. She uses a "Distructo Disc" and ruins Goten and Trunks' identity and are disqualified. They fly away and #18 fights Mr. Satan. #18 lets Mr. Satan win if he gave her 2 million zeni. Mr. Satan agrees and wins the tournament. It was now Gohan's turn, as Kai-o-shin is in shock of seeing Goku and Vegeta fought. Dabura shows up and the battle begins. It's an even match, but Gohan was stronger. Vegeta gets angry of the long fight and Dabura has an idea and retreats. Telling Babi-dee about Vegeta being evil (because Babi-dee can "charm" evil hearts.) and Babi-dee charms Vegeta. Videl meets Goten and Trunks what's happening about Babi-dee and Majin Buu. The two are REALLY excited and fly to the battle where Goku and Vegeta are at. The fighters are transfered back to the tournament, by Babi-dee's magic. Vegeta is now Super Saiyajin 2 and kills thousands of people in the stadium to make Goku fight him. Babi-dee is in shock because he lost control of Vegeta (from Vegeta's pride.). Goku agrees to fight and the fighters disappear to another location. Gohan and Kai-o-shin go back to the ship to stop Babi-dee and Dabura. Goku and Vegeta fight a rough battle. Just as Gohan and Kai-o-shin arrive at the base of the ship, Majin Buu was about to be released (because of the fight of Majin Vegeta and Goku). Majin Buu was free (which is fat buu here). Goku gets knocked out from Vegeta's sneaky move. Vegeta senses Majin Buu's "ki" and flies towards him. Buu thrashes on Dabura and Gohan, he turns Dabura into a cookie and eats him. Vegeta fights Buu, but Vegeta ends up self-destruct. Vegeta is killed, but Majin Buu was still alive (Piccolo and Krillin now back to normal from Dabura's death flee with Goten and Trunks.).
Shenlong is summon by Bulma and revives all the people killed at the Tenkaichi Buboukai. Goku shows up and tells the dragon that's all they need and will ask for the 2nd wish later. Now the dragonballs will be able to use in 6 months. Majin Buu and Babi-dee destroys a lot of cites. Trunks goes to his house to pick up the Dragon Radar and Goku tries to stop Majin Buu. Goku smiles and suddenly turns Super Saiyajin level 3. The fight was almost even, but Goku's energy was draining badly because of the Super Saiyajin 3 stage. After Goku leaves, Majin Buu is pissed off my Babi-dee and kills him. Mr. Satan meets Majin Buu and they end up being friends. Majin Buu heals a wounded puppy and love each other. Byt, Buu's puppy is killed and gets healed. Mr. Satan is then shot, as Majin Buu heals him and yells at Mr. Satan to run away. Buu releases all the evil in him. The evil form leaves fat buu's body and is now Super Buu. Super Buu fights fat Buu but wins, and fat Buu was turn into chocolate. Super Buu eats him and turns powerful.
Goku shows the fusion technique to Trunks, Goten, and Piccolo before his time was up. After Goku left, Piccolo trained the two fighters. Finally, after several tries, Gotenks was born. Super Buu arrives, as Goten and Trunks train. Super Buu and Piccolo enter the spirit and time room where Goten and Trunks were at. A huge fight begins, Gotenks Vs. Super Buu. Because of Gotenks silly games and pranks, Piccolo blew up the doorway out of the spirit and time room. Now they couldn't get out. Super Buu screams in anger and opened a portal. He gets out and turns all the Z fighters at the palace into chocolate.
Gotenks turns Super Saiyajin 3 and screams loudly, and opens a portal out. SSj3 Gotenks and Super Buu fight again. Gotenks was about to win until the fusion wore off. Suddenly, Gohan shows up (after being at the Kai-o-shin planet and stronger than ever from the 15 generation Kai-o-shin.). Super Buu tricked Goten and Trunks to fuse and absorbs Gotenks, and Piccolo. Gohan fights a stronger Buu. Goku recieves the pottora earings which is a fusion from the Kai-o-sin. Goku arrives after Gohan beaten badly. Gohan is then absorbed, and Goku is in a jam. Goku meets Vegeta and fuse into Vegetto. Vegetto fights Super Buu. Buu turns Vegetto into a milk ball, but Vegetto still beat the shit out of Buu. Vegetto is then absorbed, and the split once inside Buu. Vegeta tears out the absorption pods in Super Buu, that hold Fat Buu, Gohan, Trunks, Goten, and Piccolo. Goku and Vegeta escape Buu's body with the other fighters. Suddenly, Buu mutates into Kid Buu. Buu laughs evilly and destroys the earth, along with the unconsious Gohan, Piccolo, Goten, and Trunks. Goku brings Dende (who escaped from Super Buu's attack at the palace) and Mr. Satan (with the dog). Goku and Vegeta fight Kid Buu at Kai-o-shin planet. After a long, hard battle, Majin Buu spits out Fat Buu (because he prevented Buu to attack Mr. Satan). Then, Goku kills Kid Buu with the Genki-Dama. 10 years later Goku fights Uubu (reincarnation of Buu) and tells Uubu he'll train him to be stronger. Pan (daughter of Gohan and Videl) is also fights in the Tenkaichi Budoukai. This ends Dragonball Z.
