In 4th War Naruto in KCM created clones actually above Kage Level. Seeing as he took down 3rd Raikage, Muu another kage, and one shot multiple Zetsu all across the countries. Madara even called a clone of Naruto impressive.
So now you have Planet Level Naruto and his army of moon level clones against planet level Ichigo who barely has long range attacks ? It’s a stomp in Naruto favor. Plus he has better techniques and can always amp himself to SO6P Levels with 3 Headed Kurama like he did against Sasuke in VOTE.
Ichigo has far less impressive feats I. His new form against Ywach and really the form only lasted like 1 or 2 chapters lol. Naruto stamina in SPSM is amazing as he fought 10 tails Madara for a while, then had to fight Kaguya, and he fought these two back to back without reverting back to his base form. So the SPSM stamina is quite large for Naruto. He then used the form again against Sasuke despite being incredibly tired from Kaguya battle.
And Ichigo who did nothing big in EOS is gonna beat Naruto ?
I dunno. Soldier only brought it up but it wasn't actually agreed upon, I do agree on banning them though. Was it discussed anywhere else? Because that is the only thread I aware of since then til now on the subject.
