He tells goku that if he does not join him he will kidnap gohan. goku charges at raditz but is stopped clear in his tracks by a knee in his stomach. Raditz leaves, then they are encountered by picollo who starts talking. Now, goku who is very impatient tells picollo to get to the point so he does and says the only way to beat their new foe is to team up goku agrees and they both fly off towards raditz.
Meanwhile raditz is getting annoyed by gohan's constant crying so he locks him up in his sayian space pod, his scouter reads a high power level coming from gohan but he convinces himself that it is broken. But his thought is quickly proven wrong when it senses goku and picollos levels getting closer. Goku and picollo then remove their weighted clothing boosting their power levels up by 100, raditz laughs at this poor atempt to become more powerfull. When they start fighting raditz beats up on both of our heroes and then finally goku grabs his tell rendering raditz paralized. But he lets go thinking raditz will go on his way packing back to planet freeza but he is tricked and beat up a little more.

Gokou and Gohan enter the Room of Spirit and Time, where one day is a whole year in there. Training for a year straight, they become amazingly strong - literally reaching a new level entirely.

Cell Saga

However, once they come out of the room, they learn of a new enemy - the monster Cell, whose gone around absorbing people through his tail, including the two androids, which allows him to reach his perfect stage.

Being a good sport, Cell holds a competition. If someone can defeat him, Cell will spare the world. If all his challengers are killed, he destroys the earth. Gohan and Gokou are the only two that stand a fighting chance against the powerful monster.

Gokou allows Gohan to fight Cell, being the only one aware that Gohan's reached a new level. Cell, too, realizes this and transforms himself into a huge time bomb - more than powerful enough to blow the earth to bits.

Knowing what he must do, Gokou transports Cell to Kaiousama's planet, where he explodes, killing Gokou, Kaiousama, Bubbles, and Gregory.

Amazingly, Cell survives, but Gohan, with the spiritual support from his dead father talking via Kaiousama's telepathy, defeats him, saving the world.

Buu Saga

7 years pass, and Gokou is living in the afterlife with Kaiousama. Another Tenkachi Boudakai is held and Gokou is granted one day of life to compete in it. On earth, he meets up with all his friends again, and meets his second son - Goten, a small boy who looks just like he did as a boy.

The heroes meet Kaioushin, the God of the Kaious, and he tells the heroes of a powerful enemy named Buu. They fight Buu and Vegeta is killed. Gokou's day is up and he's forced to go back to Heaven, where he meets Gohan, who isn't dead, but's training to fight Buu with Kaioushin.

Gokou helps train Gohan and switches status with KaioSama so he can come back to help fight Buu - KaioSama falls drops dead on his planet, and the halo over Gokou's head disappears...then, KaioSama stands back up, a halo over his head.

Gokou departs to fight Buu, a little after Gohan is absorbed. He arrives with Fusion Earrings, desperately seeking someone to fuse with. It seems like he'll be forced to fuse with Mr. Satan, until he senses the Ki of Vegeta.

Vegeta, who was sent by the Gods of the Afterlife, arrives just as Gokou appears in front of him. Gokou suggests the two fuse together, but Vegeta refuses. Gokou held back from fighting all out on Vegeta earlier when he was Majin Vegeta, and this insults Vegeta. However, Gokou eventually persuades him to fuse, and the two form Vegetto - the strongest character in all of Dragon Ball.

Vegetto allows himself to be absorbed by Buu so he can rescue Gohan, Piccolo, Goten, Trunks, and Fat Buu from inside of Evil Buu. Eventually, Vegeta comes up with the idea of a giant Genki Dama. Goku forms it, using the power of everyone from Earth, as well as the inhabitants of the afterlife, and other planets, and eventually, Evil Buu is overwhelmed and killed.

10 years later, Gokou meets Uubu, the reincarnated form of Evil Buu, who is good and pure, at a new Tenkachi Boudakai. Gokou goes off to live with and train Ubuu, overwhelmingly excited with the concept of getting to spar with Uubu.
