if Naruto can tank an attack of that magnitude then his inferior version would tank it as well although with a bit of damage. And yes Pain did take damage too as manga clearly implies. But we don't know where Pain was in the blast. But Naruto was in epicenter because he didn't shoot the BB off and it was right in front of him
Bold is based on literally nothing nor does it prove that an attack that put a hole in V3 Susanoo is survived by KN4.
And whether or not he took damage isn't what is being argued here obviously. Whether or not him and KN6 received the full blast is what is being debated here and it's a fact that they didn't as Deva and the other paths of Pain (including Asura Path who is far more durable than any other Pain including Deva) have been destroyed by far weaker attacks.
-Naruto charges Bijuu Dama.
-Pain slams him with a rock.
-Trajectory is changed.
-BD is fired.
Can KN4 counter the summon by sending chakra hands to touch its body to burn it? Like how Orochimaru was burned from touching the chakra hands.
How powerful is KN4's shockwave compared to baku's suction
If he does that then Danzo simply obliterates him w/ Fuuton, and KN4's shockwave can't be compared to Baku's suction because one isn't an attack, the other is. Baku's suction is strong enough to immobilize Susanoo however so take that how you will.
