Baby: Ten years passed since the end of Dragonball Z. Oob trains with Goku. Gotten and Trunks are adults. Pan is 14 years old. Satan is balding. Krillan has a mustache and gray hair. Since the defeat of evil Boo, there was peace on earth... Pilaf has finally gathered all the dragonballs to wish for world domination. Shenlong is summoned. Without notice, Goku enters the scene. Pilaf, surprised to see Goku after all these years, starts to wish that Goku was still a kid so that he could be easier to defeat. Shenlong takes this for the wish and turns Goku back into a kid. Pilaf runs off again and is never seen again. Goku returns to his house and tells about what happened. Popo appears and tells Goku that there are Black Star Dragonballs scattered in space. Goku decides to find these dragonballs to restore himself to his normal form. (The dragonballs of the Earth can only be used to grant wishes once a year). More surprisingly, Popo tells that these Dragonballs must be gathered within a year or the Earth will explode! Goku and Trunks get on a space capsule to set voyage on their new quest. Pan sneaks aboard the capsule and accidentally damages an engine. The space capsule crashes into many planets. In these planets, our heroes acquire the Dragonballs and meet a cast of minor characters. (It was these boring scenes that made people hate Dragonball GT at first.) During these scenes, Goku and Trunks enter their SSJ for the first time in Dragonball GT to battle the minor villains. Pan also fights, but spends most of her time watching the Super Saiyan's in amazement. In addition, our heroes meet Gill, a little robot who swallowed the Dragonball radar. As a result, our heroes take him on their journey. Our heroes land on Dr. Mau's planet. Dr. Myu is an evil scientist who creates a bunch of cyborge and robots. Gill is one of his creations. Trunks is kidnapped. Pan tries to rescue Trunks while Goku fights Rudo, a creation of Dr. Myu. Rudo is killed. Gill helps Trunks and Pan escape and our crew returns to space. One of Dr. Mau's project is Baby. Baby is really the only surviving Tsufurujin. Planet Plant, his native planet, was destroyed by the Saiyan's back when the Saiyan's worked as mercenaries for Freezer. As the only survivor, Baby wants revenge on all Saiyan's, innocent or guilty. Dr. Myu found Baby in space and saved him. Baby has the power to take over bodies and acquire his victims power. Baby takes over Dr. Mau's body and kills him in the betrayal. Goku, Trunks, Pan, and Gill finally return to Earth with all seven Black Star Dragonballs. Goku takes them to Popo to secure them for later use. However, Baby also lands on Earth. Slowly, he takes over the bodies of Trunks, Gohan, and Gotten. Even when he leaves their bodies, an egg is left in their brain. This egg makes its victim a zombie of Baby. (When Gohan was Gohan Bebi, he fought and injured Piccolo with a fireball). Baby finally finds a body that satisfies him, Vegeta's! Vegeta's body is taken over and Vegeta Bebi is formed! Soon, everyone on Earth become zombies of Baby except Satan, Pan, Boo, Oob, and Goku. Popo, also a victim of Baby, uses the Black Star Dragonballs to create another Planet Plant for Baby. (By this time, Dragonball GT began to get interesting and unsatisfied fans began to take up interest in this sequel series to Dragonball Z). Oob faces Vegeta Bebi and is defeated. Fat Boo joins the battle and is killed. Boo's body is near Oob and his spirit enters Oob. The two fuse and Oob learns that he and Boo were originally one. However, even with this fusion, Oob is no match for Vegeta Bebi. Goku faces Vegeta Bebi. Vegeta Bebi is stronger and easily defeats the young Goku. Goku powers up to SSJ3, but is still defeated; Vegeta Bebi can also power up to level 3. Pan hides in the background and watches the fight. Goku gets defeated by Baby's black death fireball and the assistant of Kaioshin came to rescued Goku from the death ball, but he was too late. Goku's soul was then gone to the gateway of death. Either going to die to hell or to heaven and get trained at Kaioshin planet and go back to earth to defeat Baby. But during the way Goku had to play a game with the gateway guy. Goku must win to go to Kaioshin and if he loses, we all know hell. Well they been playing for a long time, (Goku may not use his powers or cheat, or he loses the game) finally Goku wins the game! And Goku was on his way to see Kaioshin. On Kaioshin planet, the Kaioshin inhabitant substances are creating a formula that will make Goku's tail grow back. (The tail is the main source of power for a Saiyan.) Goku's tail is only partially grown. Kaioshin pulls it to make it reach normal length. Goku returns to planet Plant to face Vegeta Bebi. After getting beaten by Vegeta Bebi again, Goku lies on the ground and stares at the Earth. The "full Earth" acts as a full moon. As a result, Goku reaches Oozaru stage and becomes a giant golden ape. (The ape is gold instead of brown because it was the Earth that caused the transformation instead of the moon). Goku is a lot stronger, but is unable to control his body in Oozaru stage and trashes everything in sight. Another change occurs. Goku acquires control over his body and enters another stage beyond Oozaru. He powers up and becomes SSJ4. The tide of the battle is turned and Vegeta Bebi is losing. The zombie Bulma creates a special magnifying glass for her husband. It magnifies the rays of the full Earth and Vegeta Bebi enters Oozaru stage. Goku gets defeated once again. Meanwhile, Kaioshin resolves that Chousui water could cleanse people from Baby's control. He goes to Sky Palace to get the Chousui water. Dende and Popo are cleansed in the struggle against Kaioshin. This water is spread to everyone. Gohan, Gotten, Trunks (now free from Baby's control) and Pan surround Goku and form a circle. Their energy is donated to Goku. Goku and Vegeta Bebi face each other again. Goku does a Kamehameha fireball and defeats Vegeta Bebi. Baby leaves Vegeta's body and runs to a space capsule to escape, but is killed. The Earth is about to explode because the Black Star Dragonballs weren't used to wish for the Earth's stability. Our heroes fly all the inhabitants to planet Plant. Piccolo decides to stay on Earth to die with it because he loved it so much. (He is still injured from the blast from Gohan Bebi.) The Earth explodes, and Piccolo goes with it. At The Nameck Dragonballs are gathered and the Earth is restored from the wish, but Piccolo is still dead. However, one thing is learned, Goku reached a new stage as SSJ4.
