Naruto was unaffected by a guy grabbing his shoulder and yanking on it hard enough to instakill someone, he just grabbed it and pulled it back in.
Are we using that key of Ichigo? I think we're using True Getsuga Tensho.
Does he really? I read his fight with Aizen, that wasn't happening.
TSO's aren't just EE, they also act as superior to Dust Release that reduces a target to dust, becoming even stronger in every capacity when Yin-Yang is added to them(As such, Yin-Yang TSBs > Aizen EE and Deconstruction, unless he's got some good layers)
He absolutely doesn't oneshot the soul, he just hits them in the soul(With Reiatsu Crush), Soul Manip resistance would treat that as a normal hit.
It would still do more than a normal attack with the same power, I believe.
Naruto also has things that attack the insides btw.
Merely having a bit of soul hax resistance do not do much against Bleach multi layered soul hax my dude. Naruto's is barely above baseline resistance.
Hollowfied true bankai ( or HoS True bankai) is his strongest form (Beside HoS unsheathed bankai) , the one from the Yhwach fight. So yes. Not that would have changed much, because Yhwach said that: " you have been changing the future countless times and overcame despair . Do you why you could do that ? Because i wasn't there" . So even weaker Ichigo could do that.
Bro was erasing mountains in the Aizen fight ,multiple times. Fullbring shikai was also creating air shockwave so powerfull , they thought it was a GT. In the Yhwach fight, HoS true shikai , a weaker form, by just flexing his aura, completely busted the palace they were fighting in. A single swing from True Shikai destroyed half the room.
Ichigo no sell Hado 90 atomic deconstruction, Onoki deconstruction is merely molecular. Upscaling from molecular still doesn't even come close to Atomic . Ichigo can touch TSO no problem.
The zanpakuto hit on a spiritual level. And again, naruto soul hax resistance is inferior to even early Bleach.
Frog katta is close to useless because of Blut vene would protect the organs. The only thing that would be close to a threat is the RasenShuriken , all of his other options , Ichigo can easily deal with.
So, any and all Ichigo's arsenal is a certain death if it hit, while Naruto would need to hit specifically RS to put him down.
