What if they teamwork together and fight Momoshiki ? In many many spolier, it proof that Naruto mode in the Kaguya Arc is the most powerful mode of Naruto ever had. Because he combined his SPSM with all tailed beasts chakra,included a little of Juubi chakra that was given by Obito and active Six Path senjutsu (give Naruto TSB). We call it : Six Path Sage Mode Senjutsu. Another Six Path Sage Mode that we seen in The last Naruto and Boruto series is only normal SPSM (not senjutsu once). The limit of shadow clones of normal SPSM is 2-10. Senjutsu once is over than 1000 shadows.Senjutsu SPSM he can use TSB to shaped it to any weapons,object that he wanted or used it to create Tailed Beast Shurriken. Making him that time much more stronger and more useful than normal SPSM adult Naruto. Sasuke Kaguya had 2 arm, made him move better,fight harder. He can use 1 hand to block enemy attack and 1 hand use sword or use Chidori to stab enemy with Critical damage. When fighting Naruto, he used his Rinnegan so much, out of limit like suck chakras of all 9 tailed beasts or shot Indra bow, his Rinnengan is weaker because all of that using. In Kaguya Arc, Sasuke Rinnengan is full power,making him that time is much more stronger. Sakura awakened full power of Byakugou(she could create the mark all around her body[sign of full power]) and combined with 100 Medicine Chakra. That Sakura had her full power. Sasuke and Naruto that time can enable to used Six Path Chibaku Tensei to seal any strong enemy. Sakura can heals Sasuke and Naruto very fast,good. => I think Momoshiki didn't stand a chance of defeat them. They will defeat Momoshiki faster than Sasuke,Naruto adult. TEAMWORKS !!!!! AGAIN !!!! FOEVER !!!!
