How much time pass between the Saiyan and end of Namek saga?

[Hitiro]

Even though it's been decades since his death?

If he hasn't been reincarnated he should be fine. And seeing as he probably kept his body for saving the Earth from Piccolo then he probably has a choice for when he gets reincarnated.

[NANLIT]

He might not even be able to be reincarnated. Just like Roshi was counted in the revival by Piccolo and his minions evn though he died via the Mafuba, Mutaito would still be floating with the rest of Piccolo's victims from his first reign of terror, unable to pass to the afterlife, correct?

[Regarder]

Unless Piccolo Sr dying passed on the victims to Piccolo Jr, and when Piccolo Jr turned good, Mutaito and others could finally pass to heaven.

Unless Piccolo Sr dying passed on the victims to Piccolo Jr, and when Piccolo Jr turned good, Mutaito and others could finally pass to heaven.

Well, it doesn't seem like he did, since Roshi and Chiaotzu were both back by the end of the Daimao Arc.
