Zoro said the attack will eliminate all of us which is wrong. The statement is his own statement, not others. It wont do jack to Luffy when full CoC Coating Ragnarok direct attack didnt do any damage to Luffy. Luffy also said its big, regarding its size not strength. Zoro having fire-cutting is the only way for Zoro to do anything to Boro Breath, its not fodderizing, its using the new hax to get better match-up. While Luffy just tanked it purely with physical and haki, so yeah its just Zoro that hyped Hakai's strength with broken bones as a result from trying to block Hakai for a moment before Law teleported him. While Sanji had no damage from chapters against YCs, so i dont see where's the need to downplay Sanji coming from
It's a statement Oda chose to tell us the scale of the attack.
Same as Luffy calling it big one despite suffering TB first hand.
Same as Kaido saying BM's back might give out just to perform this attack.
Same as Kaido and BM both looking shocked as hell when Zoro stalemated it.
Same as Kidd saying blocking that thing even for a second is hella impressive and thanking Zoro.
Same as Kidd/Killer/Luffy running away from the attack with a shocked expression.
Same as Law shitting his pants and saying how it is possible for Zoro to do what he did to prometheus (not even Kaido stuff) after taking that attack.
Imagine Law saying "How is Sanji strong enough to be defeated by two YCs without doing any damage..." or Kidd going "Getting thrown away by them and doing nothing to them in return is such a huge feat! Thanks!" or Luffy/Kidd/Killer running away all terrified on sight of King and Queen.
Dude, no. Just no. You don't even need to be smart to tell that any comparison made is beyond nonsensical.
