1. So basically you have no counter to that? Your excuse is that it's a bad strategy because it doesn't involve his whole team. So what your saying is that Kabuto therefore must stand there and allow SS to hit him because you don't want him to use hiding like a mile to avoid it? Great argument. You also didn't say anything about his ability to liquify his body so that he doesn't receive any damage. He doesn't even need oral rebirth here.
- Bringer of darkness is useless because white rages light completely overcomes the darkness and the effects also paralyse Hashirama temporarily as well. Bringer of darkness also fails because these are all sage mode users, so they can sense and feel everything going on around them. Not sure why you're bring other jutsu into this, my only gripe was you saying SS soloes, so I'm only talking about SS.
2. SS does not bypass Minatos area of FTG. Or are you forgetting how minato set up his markings to cover a large area around the ten tails so fast that no one saw, noticed or detected him. Or how he used space time barrier to teleport the ten tails beast bomb. Now correct me if I'm wrong, but aren't both the ten tails and the bomb both larger than SS. I certainly know that the bomb made Gyuki look like an ant. And yes the space time barrier will work, if it's coming straight towards him (which it will). It's funny that you say it won't work on a Juubi sized structure, yet minato has already pulled off such a feat in the manga already. And the location is the final valley, so throwing a kunai into the valley to the bottom of the deep lake, minato can slow it down by teleporting it into the ditch/valley. And if the op was only referring to the final valley lake area where Naruto and Sasuke fought, and not the acres of land beyond it, then that's even better because SS is way too big to even be used in such a space without crushing everyone including Hashirama's team. Unless you think the final valley is a large enough location to actually use SS, and on water -_-
3. You're saying minato cannot get away from SS on foot with his body flicker speed? Yeah right, that thing is slow as ****. It ain't getting anywhere near him if he runs. We've seen him cross huge distances in the blink of an eye before, so if he's going full speed at a constant rate, that crap is never getting near him. I don't know where you got the idea that SS is a nuke, because it's not affecting the whole area, there is land upon lands of space to run to. And you don't need incredible speed to outrun it either, once again, Madara ran straight into it. I honestly can't believe you think SS can't be outrun, it's not a franking rocket jet. It's like a tank, big, durable, powerful but not very fast at all. Kabutos liquid body won't be affected and minato easily outruns it while carrying Naruto or FTGing him to safety.
