HUGE PLOTHOLE INCOMING.
Remember the wish to revive EVERYONE that was killed by Frieza and his men? What about the Saiyans?
When Guru is on Earth (episode 102), he tells Gohan and Bulma that when a person (in this case Krillin) is revived once, he can't be revived a second time using the balls. When he gave his authoritah to Moori, apparently Moori upgraded the balls so a person can be revived twice or more, because Dende says this in the next episodes; but I think it's only in the Japanese dub.01:26, June 18, 2013 (UTC)
- oh, nevermind this. it was probably anime filler what guru said. because dende says that he can be revived just after moori became the new elder, giving him no time to upgrade the balls. 17:09, June 18, 2013 (UTC)
