Probably, but enough to be a factor against SS or SM Mokujin? No.
Enough of a factor to use the combo that caught Edo Madara, before activating PS. Difference here is Hashirama needs to make hand signs.
Doesn't matter when he starts with it. As long as he gets the chance to use it, and none of these guys can take him out before that happens.
How so? backpack Ay caught Edo Madara off guard, so that goes for Hashirama, yet alone their power boost.
And that's the issue. Will the boost be enough to take out SS?
I dont see why not. Base Jinton, powered Tsunade covered range = Half the size of Meteor/PS. Rationalizing this, what would 3x boost of Jinton be, yet alone Tsunade boost cover. And what would a BM cloak boost cover in addition?
Gaara is literally useless, same goes for the others when it comes to support to let him prep Jinton. If he's on SS, all he needs to do is hit him with SS. Moves as fast as Kurama's Bijuu Dama and has a wide AoE.
Ok thats only assuming I implied that SS is already out, which I didn't.
Yet we've never seen a cloak grant a massive boost in speed like it'd do to Ninjutsu.
Not seeing it doesn't mean its not powered up. Unless you want me to conclude that cloaking Lee should have been pointless if he gain no physical boost, since he has no ninjutsu.
And that isn't a BSM boost. It's only a BM boost. They have no Senjutsu Chakra.
What made you conclude that? The gown is linked to BSM Naruto. When K11 enter PSKurama Naruto/Sasuke their chakra mixed with Naruto.
