After Gohan defeated Cell, the Z Fighters use the Dragon Balls to undo the damage that Cell caused. They try to bring back Goku but he decides to stay in Other World for the safety of his friends and family. Krillin then uses the last wish to remove the bombs out of Android 17 and 18 because Shenron could not turn them human. I DO NOT OWN DRAGONBALL, DRAGONBALL Z, OR DRAGONBALL GT.
