[THEORY] Hashirama most likely died by this cause.

[EliteKage]

Remember how kakazu and hashirama fought?
Now that must of been a huge roflstomp right?
But kakazu is smart and most likely acuired some DNA to save for later.
Hidan wasn't his partner back then I think so he kept it waiting and waiting for his revenge.
Until he was partnered up with hidan they bickered a bit and bam dead.

Thats the only way I can see hashirama dying. Since no one can beat him

 

[BREAKD]

no... juts no...

 

[Reaper]

Nope,not at all
Like 0 chance

Akatsuki was formed long after Hashi's death
Hidan and Kakuzu met after hey joined the Akatsuki

 

[Elio]

Nope. I don't think so...

 

[foxyladyland]

what r u saying that kakuzu stole hashi's dna or something?

 

[-Raviel-]

He died of wood cancer man......shit even this is more plausible than your theory

 

[muutobirama3rdraikagemizu]

[Fighter2011]

He died from the wounds he got while fighting Madara. Wanna bet? Lol

 

[Stark]

I'm baffled that someone would even think of such stupidity.

 

[l Forgotten l]

no............

 

[Saikyokami]

hashi died from aids

 

[Reaper]

His wood was too big and not enough blood went into his head U_U

 

[Arcanor]

Kakuzu had no motive for collecting DNA from his opponent. Even less chance since Hidan actually needs blood for his ritual. Furthemore, he would have no profit of killing him like that. And then, there's the timeline

 

[foxyladyland]

He died from the wounds he got while fighting Madara. Wanna bet? Lol

this is a nice idea seems possible that people like,

 

[Nakamazi Itchigo]

Nope I highly doubt that :|

 

[The Big Boss]

he got a splinter that caused gangrene and he ate chopper's medicine

 

[ReeseKage]

Be nice y'all. Kakuzu took the hearts and the elements and or jutsu of everyone he killed. He stated that he once fought against Hashirama but never said he killed him. Of he did then one of his hearts would've been mokuton. He ain't have mokuton.
