Vladosaurus wrote: But honesty, how is Naruto fighting with the same power and same speed in base as he does in SPSM + chakra cloak? T The idea of "base" Naruto is largely artificial. Keep in mind that he can use SP chakra regardless, and he can freely use Kurama's chakra. Meaning that in "base" he can easily be 80% or so the strength of his SPSM form.

It seems to tear Boruto's arm not unlike a Rasenshuriken, flies off not unlike the Rasengan thrown from the Kote (Movie) or the Vanishing Rasengan. Given Momoshiki's power, Reincarnative powers ought to be in his reach, implying it can hurt him permanently (not unlike Naruto and Sasuke's arm being permanently destroyed). Boruto could pocket it, but Naruto now has advanced knowledge of Uzumaki seals so he might've just added some sort of Transcript-esque power to it.
 * Boruto didn't just make the gigantic Rasengan invisible, but he pocketed it. How did he do that? It's clear that he didn't use his BS-dojutsu to do it because it wasn't active (and wasn't it established that it the one that opened the portal during the clash between him, Mitsuki, and Sumire, therefore confirming that it can't use space-time ninjutsu?)
 * Boruto activating his BS-dojutsu before he struck Momoshiki and during the clash implies that it gives him some sort of boost, otherwise it would be completely pointless activating it. This apparent boost wasn't seen during the other times he activated it.

The way Boruto uses the Jogan's power against Momoshiki (the way he slaps away the hand) is a direct reference to how Momoshiki blocks several attacks earlier. So it definitely implies some sort of power-up mode.
