Anyone can USE poison. Poison also takes prep. "Lace it"? :wut: kurama wouldn't have let Naruto die anyway, plus plot :bdpf:
Tell me more about how anyone OP or anyone at all got poisoned after that. :Sparks:
Lol anyone can use poison? Well yes SENSI OBVIOUS.
Can anyone make it? And counter it? NOPE!
No one in the sand village had the expertise Sakura instantly displayed off the rip. I mean Chiyo was credited throughout the entire NV as being it's strongest poison expert only second to Tsunade but she couldn't even articulate a word when faced with Sasori's poison. Yet Sakura with only three years of training under her belt extracted it then nullified in the same day, Sasori himself said that analyzing it would take the up most attention to detail and that it was over the entire sand villages head ( including Chiyo).
Now as far as the rest if your post goes, it's fanfic.
Naruto was COMPLETLY UNCONCIOUS and by Kakshi's own admission in eminent danger to which is why he requested the antidote expeditiously. You don't know how the 9 tails would've responded or if he even had the means of nullifying the Toxins in Naruto's molecules lol.
Unless Minato sealed random antidotes to poisons with Kurama but that's more fan fic!
