How did Hashirama die? and if nobody know's how he died could it be that he did what Madara ask and killed himself becouse he couldn't kill is brother Tobirama?
yeah it had to be suicide or some sort of disease that even he couldn't recover from like goku had the heart parasite cause if madara couldn't kill him and he could live off of his cells for like 100 years then hashirama should still be alive today albeit very old (tsunade is old but still youthful in physical energy) xd
hashirama fought madara again when he was hokage and madara had 9 tailed fox, he thought madara died, hashirama died young before or during the first ninja world war
Yeah I didn't remember how he died so I'm going with suicide but somehow Madara never found out or he did and felt guilt for asking such a thing and became even more evil
He died at young age cause when Oruchimaru reanimated Hashirama(1st hokage) Tobirama(2nd hokage) they were young and i don't think Oruchimaru did something with their bodies to make them young
