Now 16 years old, Gohan embarks on his first day of high school. But blending in is almost impossible for a Saiyan, and it gets even tougher when a celebrity classmate gets suspicious of a certain blond man thwarting criminals around town.

Gohan asks Bulma to make him a disguise so that he can continue to fight crime in the city without being recognized. Wearing his new outfit, the defender of justice makes his grand debut in the city by helping Videl thwart a gang of criminals.

Gohan teaches Goten and Videl how to fly. Goku continues his training in Otherworld while Piccolo and Vegeta prepare themselves to face him in the tournament. Vegeta is stunned to learn that young Trunks and Goten can already turn Super Saiyan.

While Gohan and Videl wait to take their preliminaries, Goku, Vegeta, and the others go to spectate the junior division, where Goten and Trunks effortlessly progress through each round until they face each other in the final round. The battle gets more intense. Goten and Trunks surprise the audience with advanced techniques. The fight between Goten and Trunks continues.

Mr. Satan plays off his defeat at the hands of the Junior Division champion. While Goku and the gang have an all-out feast, Trunks and Goten plan to get into the Adult Division drawing. A mysterious stranger approaches Goku, keen to fight him.

The adult division rounds finally begin! Piccolo must put his skills to the test against a mysterious opponent—but not before Krillin steps into the ring.

Spopovitch continues his savage assault on Videl, who refuses to admit defeat.

Goku and the others join the Supreme Kai in his search for Yamu and Spopovitch. As they travel, Shin explains what the devious duo were after and warns them of an ancient evil known as Majin Buu.

The evil wizard Babidi gives his henchmen a rough homecoming before turning on our heroes. Was this their plan all along?

To find Babidi, Goku and the others will have to fight their way through various opponents waiting on his ship. Vegeta steps up to handle the first stage, but Babidi uses magic to give his opponent the upper hand.

Back at the World Martial Arts Tournament, the crowd is getting restless. With most of the Z Fighters disqualified, Mr. Satan calls for a battle royale between the five remaining combatants.

As Dabura meditates to bolster his power, Number 18 gives it all she’s got back at the World Martial Arts Tournament. She can’t read Mighty Mask’s sporadic movements, but she refuses to go down without a fight.

Dabura emerges to face Gohan in a one-on-one battle. With Mighty Mask defeated, only Mr. Satan stands between Number 18 and the tournament’s prize money. Good luck Mr. Satan!

Bulma, Chichi and the others search for the last Dragon Ball so they can resurrect the people Vegeta killed. Meanwhile, Goku comes up with a plan to defeat Majin Buu.

Bulma resurrects the fallen spectators, and Goku rushes to ensure she doesn’t use up the rest of her wishes too soon. Buu continues his rampage and Babidi makes an announcement to the world.

Babidi reaches out to the people of Earth, demanding they give him Piccolo, Trunks, and Goten. If they don’t comply, Majin Buu will wipe out the population.

Gohan finds a new weapon in the Sacred World of the Kais. Goku struggles to teach Goten and Trunks the Fusion technique.

Trunks is sent on a special mission while Goku distracts Babidi and Buu with an earth-shaking display of power.
