What if Goku was never revealed to be an alien?

[ABED]

Goku would have caught the hear virus nevertheless. I remember Trunks saying that many people succumbed from the virus.

True, but Goku would likely survive because someone would come back to give him the cure.

Goku died a while before the androids murdered everyone else on the Dragon Team. It was only then that Bulma built the time machine, until then they had accepted his natural causes death, she simply decided to save Goku too, mainly because they wanted his power to tip the android fight.

I know, why are you telling me this? How does this change anything I wrote?

The story would have become repetitive earlier if it had continued with Dragon Ball's structure so in a way I'm glad that Dragon Ball Z introduced a new plot structure though I'll always miss good ol' kid Goku flying around the world on the Nimbus, fighting strong guys and regularly searching for the Dragon Balls with Bulma.

It seemed like you were implying that the time travel trick was mainly or exclusively to heal Goku. I'm not entirely sure why I thought you meant that though, you could have still meant it'd happen later.

Even if Toriyama hadn't thought of making Goku an alien, I don't see why Toriyama would decide Goku succumbed to the virus.
