What is the biggest unsolved mystery in naruto?

[minamoto 👑]

Tsunade had no b00bs when she was young.even jiraiya and hiruzen made fun of it in past

how she was able to grow these huge b00bs all of sudden?

May be PNJ or another asspull.

It is a mystery but likely died due to age and natural causes. Mine would be is who is Jashin really and how did he give Hidan immortality?

Hidan was not given immortality, he got it through experiments, apparently.. According to Wiki and the Naruto games.

But, I do agree with your thoughts...

Tobirama became Hokage very shortly after Hashirama so it seems unlikely he would have died of old age. My theory is that he exhausted his life force from the overuse of mokuton in his fight with Madara and either died immediately after or shortly after.

His healing might have also played a factor in increasing his age at a faster rate, just like Tsunade. That or a rare disease.

Hmm well you can't really trust the games as they are far from canon but that could be interesting. Who conducted these experiments?

Hashiramas death is no mystery. He died in the war. He was killed by the enemy. Plain and simple.

The biggest mystery unsolved would go to Prime Hiruzen and how strong he was. He was a god but we never got to see that power or even events that depict it (like Hashirama and Hagoromo, the other God of Shinobi) besides Hanzo sparring the Sannin in fear of Prime Hiruzens wrath, but thats not much.
