He was dead for like 2 days. Goku went up to Kami's Palace and managed to request for him to revive Shenlong by having Popo tape his "model" back together using superglue before he breathed life back in him.
Dende said in Super Hero that an older Namekian can do it, so Muri being the oldest surviving Namekian (other than the new retcon characters in Super and Daima) should be able to.
Anime-wise, maybe not. He did date Maron briefly, and she's probably the type to spread her legs easily.
Manga-wise, I think he, Yamcha and three-eyes are all virgins :troll
This just speaks for itself:
Dates a hot chick for a fucking year and still no first kiss. No wonder she left him...
What did you think of the battles against the rest of the Androids and Cell? I thought it was stupid how they omitted Trunks vs. Cell and the Final Flash scene.
I think MUI is at a point where it can't be amplified by stuff like SSJ, kaioken or Oozaru anymore personally. Otherwise Goku would have tried to use something to boost MUI's power after stabilizing jt.
