Shizune
Lmao remember that time Shizune led a tiny village against the 5 Great Nations in a World War with just the toxicity of her poison?
No but i remember kabuto saying that her poison could kill witj only one breath. Not even sasori's poison could do this
Sorry, no contest.
Hanzo simply breathing (even with his mask on) would accidentally kill his own men in the same room if exposed to him for too long.
Doesnt he have a poisonous sack inside or something?
Yeah, he found an insanely rare salamander in his village and immediately was turned into a child weapon. Honestly, his backstory is likely just as f*cked up as Gaara, Sasuke and Naruto's.
I don't think Sasori's poison was instant kill. It was canonically stated that the poison he used on Kankuro would kill him in the time span of three days. Som if I had to make an educated guess on who had the most deadliest poison, it would for sure, be Hanzo.
Sasori probably.
I believe what made Sasori's poison so deadly is the fact that he had majority of his weapons were laced with it which made any attack from him lethal
Sorry, no contest.
