of course
Yes. Goku is still alive. When the dragonballs went into him he became immortal. How do you think he is still alive at the world tournament a hundred years later.
goku comes back to life many times
During the fight with Buu, Goku was dead.
When Shenron took Goku away into the sky at the end of Dragon Ball GT. No one Really knows what happened to Goku. My theory is that Shenron took Goku away because he was the strongest being(except for Shenron) alive. Shenron fused the dragon balls with goku for immortality so when Goku was needed again, pretend in a hundred years, he'll still be alive. But if you ask me, Dragon ball GT is really lame. Enemies like Freeza, Cell, and Majin Buu(From dragon ball z) is something way better than Baby, Super 17, and Evil Shenron.
Goku turn into kid Goku in episode 1 or Dragonball GT because Emperor Pilof accidentally wished for Goku to be a kid again.
Dragon Ball Z - 1989 Goku's Alive 3-40 was released on: USA: 3 November 1999
pilaf used the shadow dragon balls and wished Goku small
if goku was able to beat broly before he can probably do it again
There is a Gt movie called A Hero's Legacy and it is about Goku Jr., and Pan is alive and Goku shows and talks to Goku Jr.
They revived Goku with Shenron but then when he died again he couldn't be revived by him again, so they moved Namek to revive the others who also couldn't be revived by Shenron. In Namek there was a dragon called Porunga and he could revive anyone regardless of how many times they had died, plus it gave 3 wishes instead of the normal 1.
Yes of course there was
Gohan has a daughter, Pan and she had a son/daughter which was never shown, and her daughter/son had Goku Jr.
