You obviously don't understand a single thing I typed. I said, they didn't know Orochimaru had it. His perfection of immortality isn't irrelevant, it only enforces the fact they knew little about Orochimaru to pass any valid judgement. Anko doesn't know anything either, she didn't even know Orochimaru's mind was literally inside the seal, she has no merit. Madara gained the Genjutsu from his Rinnegan he got from the tree, even if he had it, he still doesn't have Amateratsu. Orochimaru isn't getting stomped by shit, Itachi had him in a Genjutsu, and mind you he's one of the best users ever, and was still able to move. Get off Minato's **** and pull some valid arguments.
١- I know what you said, and I am telling you that they know what Oro has except for one jutsu. :dunno:
2- His immortality is useless against the sealing jutsu. Kurama is immortal, yet he got sealed away.
3- Lol, you are the one to say "Get off Minato's **** " XD
You're beloved Oro got stomped twice by itachi in matter of one second, and he couldn't handle hebi Sasuke.
and even IF we go with your argument that they did not know about Oro's power, look at what happened to Oro
while fighting OLD Hiruzen, he barely survived. lol
and since Minato is stronger than old Hiruzen, and actually even Hiruzen from the Kurama's attack was weaker than
Minato, how would Oro even stand a chance? He even admitted that If Hiruzen was 10 years younger he would have killed him (13 years younger, he(Hiruzen) was still weaker than Minato)
Tell me how is Oro going to react to Minato's speed exactly?
