Dragon Ball GT episodes
A Grand Problem
A Grand Problem is the first episode of Dragon Ball GT that aired on American television. It is a recap episode created by FUNimation Entertainment to work around the first 16 episodes of the series, as FUNimation did not think the more adventure oriented tone of those episodes would work well with western audiences.
The episode begins with Goku and Trunks being wrapped up by some robotic ooze. Everyone wonders how it started, so a flash back occurs to Goku training Uub. He and Uub have become completely equal in strength, and after 10 years of training at the lookout Goku feels he's trained Uub in every way possible. He decides to head off towards home when a mysterious light appears.
The scene flashes to Emperor Pilaf and his minions who have snuck onto Kami's Lookout. They are looking for Dragon Balls, but not just any Dragon Balls. They are looking for what are called the Black Star Dragon Balls. These Dragon Balls were created by Kami before he and King Piccolo split into two people, so they didn't turn into stone because King Piccolo and Kami were still alive as Piccolo.
They found these mysterious Black Star Dragon Balls in a hidden chamber under the lookout, and so Emperor Pilaf called the dragon forth. Goku arrives and recognizes Emperor Pilaf, and when Emperor Pilaf realizes who Goku is he wishes Goku was a little kid so he could beat him up. Ultimate Shenron grants the wish, and Goku is turned into a little boy of 12 years old.
King Kai then contacts Goku. He informs Goku that he must gather the Black Star Dragon Balls back to the Earth within one year, or the Earth will blow up. Goku enlists the help of Bulma who builds a new spaceship, and Vegeta makes Trunks and Goten prepare to go look for the Dragon Balls as well. Just before Goten boards the ship, he gets a phone call from his date. Pan has snuck onto the ship, so she takes off with just Goku and Trunks on board.
