Piccolo picks up where Goku left off and continues to teach Goten and Trunks fusion. Goku returns to the dead.
Goku, who used up all but thirty minutes of his earth time by fighting Buu, gets back to the lookout to teach Goten and Trunks the fusion dance. Although it looks silly the results are an unimaginable gain of power.
Goku starts to teach Goten and Trunks fusion, but as Babidi and Buu are about to blow up West City, and the dragon radar, Goku goes to distract them while Trunks goes to get the radar.
Babidi says that if Goten, Trunks, and Piccolo are not found, then in five days the earth will be destroyed. The World Martial Arts Tournament Owner goes to Babidi with the names of the people, but Babidi kills him. Piccolo wants to give himself in.
Kibito (who was revived by the Dragon) finds the Supreme Kai and Gohan. Goku delivers the news of Vegeta's and Gohan's deaths to everyone. Babidi gives a warning that if the three people that attacked him (Piccolo, Goten and Trunks) and Buu don't show in five days they will destroy the Earth. Then Buu turns a whole city to candy as proof of their power.moreless
For the sake of his son and other loved ones, Vegeta chooses to sacrifice himself by using Final Flas to try to kill Buu. Trunks and Goten try to stop from doing so, and for their own good get knocked unconscious. Vegeta unleashes his full power, killing himself, and vanishing in an aura of light.moreless
The Supreme Kai takes on Majiin Buu, but his mental techniques seem to have little to no effect on the pink Demon. Buu playfully enjoys himself by beating the tar out of the Supreme Kai.
Gohan's attempts to stop Buu from hatching are in vain. The egg hatches, much to Babidi's delight. However, the egg contained nothing! Only a pink blob of smoke! Babidi started crying at the mistake. Supreme Kai is once again confident, but the pink smoke in the air forms into a body. The smoke clears and Buu appears! He lands, and starts waddling around like an idiot. Supreme Kai tells Gohan that Buu is supposed to be this way. Buu stops, then just stands still and taps his foot impatiently, obviously waiting for his master, Bibidi. (Buu was locked up before Bibidi was destroyed, so Buu does not know of his master's death.)moreless
The energy Goku lost in the fight is enough to bring Majin Buu back to life. Babidi transports the egg, himself, Dabura, Supreme Kai, and Gohan to the outside. Vegeta teaches Goku about humiliation. Gohan makes attempts to stop the egg from hatching.
Vegeta and Goku fight in a battle to determine who is the stronger. Vegeta, who is now pumped up as Majin, now matches Goku in power.
Vegeta is now Majin, and Babidi transports them to the tournament. Hercule takes it as a challenge, but backs off. Vegeta destroys half of the stadium, then challenges Goku. Goku accepts.
It all comes down to 18 and Hercules. Despite making a great effort, Hercule knows that his chances are slim. 18 bests him at every turn, but then really hits him where it hurts – his pride. She has a deal for Hercule – he can keep the title and the prestige in exchange for her getting the prize money (plus a nice bonus). With no other choice, Hercule agrees and hardly anyone else is the wiser. Trouble looms, though, when the three Z Fighters and Supreme Kai are confronted by Dabura. Gohan must now step up.moreless
When Mighty Mask transforms into a Super Saiyan, Android 18 learns that he is really Trunks and Goten in disguise. She throws an energy disc that breaks the two apart. Trunks and Goten are disqualified for being underage, and for fighting together.
The tournament is still in disarray following Gohan and Kibito's disastrous match. Boredom is spreading throughout the stadium. Hercule makes a suggestion – one final match between those that stayed behind. Things certainly liven up once the fighting gets going. Jewel and Killah end up rather easily dispatched. Only three hold any bragging rights – Android 18 and Mighty Mask (aka the disguised Trunks and Goten). Hercule practically becomes a spectator – fearing that his defeat is inevitable.moreless
Goku transforms into a Super Saiyan and overwhelms Yakon with excessive energy. He blows up and the fighters proceed to Stage Three, where Babadi's best fighter awaits them.
Vegeta continues his fight against Pui Pui, and much to the surprise of the Supreme Kai, Vegeta is stronger in every way. Babidi tries desperately to give his fighter the advantage. By using his magic Babidi changes the landscape of his ship to Pui Pui's home planet, and there is ten times the amount of gravity there than on Earth. But still Pui Pui's efforts are proved useless as Vegeta makes quick work of him. Now the Z-fighters move on to level 2 to face the energy eating demon, Yakon.moreless
Flanked by Dabura and Pui Pui, Babidi is pleased with Yamu and Spopovitch's success. However, now that he has Gohan's energy, he now no longer has any use for them. He has them cruelly and instantly killed. On a nearby cliff, the present Z Fighters, Supreme Kai and Kibito are anything but settled. Naturally, things will only get worse. Meanwhile, Gohan and Videl are heading their way.moreless
