This opens up a whole new can on how I view SPSM Naruto vs Base Naruto (And people will come at my throat for it, I know...). If you want me to expand on this, i'll do it later but this is the "
Short Version": SPSM isn't a huge buff over Base Naruto, thus, Fused Momoshiki isn't a "
huge" buff over Base Momoshiki. Base Naruto is able to hold his own, High-Diff, but is eventually overwhelmed.
- Base Momoshiki Physically ~ Base Naruto Physically
- Fused Momoshiki Physically ~ SPSM Naruto Physically
My reasoning for this, and again, I will expand on it later if you want, is that Naruto is buffed in Base the same as he is in SPSM due to having SPC. "Kurama's Chakra Strength" is much weaker than the SPC he received from Hagoromo. Thus, the buff Naruto gets from stacking SPC & Kurama's Chakra is not significant, in my eyes. Yes, he gains things that he doesn't innately have without its usage (Chakra Cloak, Enhanced Sensory Capabilities, etc), but from a stats perspective, the "Buff" isn't significant.
By the way, when I say that, I mean much less than 2x (Not even close to it). I consider a "Significant Buff" 2x and up (Speed Stats aren't factored).
To illustrate this, I think Base Naruto post receiving SPC (War Arc) one shots BSM Naruto (War Arc), whom I have far more stronger than a hypothetical 100% Kurama Biju Mode Naruto (War Arc).
