Shenlong does have brainwashing abilities, as shown when he erased Buu from people's
memories. Therefore, everybody on the planet would have been brainwashed, except
Goku and the other ones who are stronger than Kami.
Bulma refuses to make them a spaceship to go look for dragonballs, since she's now
brainwashed and only obeys to Pilaf. Eventually, Pilaf is convinced by Z fighters about
how urgent the situation is, so he commands Bulma to build the spaceship.
The rest of GT continues as we know it, with the Z fighters fighting the villains (Baby,
17 etc), except Pilaf remains ruler of the world, even though he's ruler in name only,
for the non brainwashed Z fighters can always set him straight if he turns
tyrannical.
Dunno, was that accurate? What do you guys think? Discuss.
