similar is not quite equivalent to "same" ( they both arent in condition to fight is my point)
similar: resembling without being identical.
there are doctors around who will try their best to keep him alive
zoro has a strong will
am sure that factors in as well.
how do you think zoro will survive sir
So Oda was writing his Story & he came up with an idea
"I'm gonna make Kaidou & Big Mom do a certain death attack & then make Zoro temporarily have to take it, and then send him back to the castle alongside other Supernova who have minimal injuries, i'm then gonna make him wrapped completely in bandages & make it cross shape & then make CP-0 put white pieces that represent alliance on shogi table in a cross shape, and then i'm gonna make Minks give Zoro a medicine that makes his condition even worse, after that i'm gonna make him see angel of death & go dark, after that i'm gonna make Franky carry him for 10 chapters & he is worried sick about him, and i'm gonna make sure all other fights are done, yonko are defeated, everyone already bandaged & taken care of instantly & announce Raid End, while Zoro's Fate is still unknown ... etc
At the end of all of this i'm just gonna make Chopper heal him & call it a day" lol
Have you people even read One Piece?
Have you seen how he was Introduced?
What he said about Death Situations? What he said about Way of Bushido?
Stabbing himself against Cabaji? His entire Fight against Mihawk?
How he was gonna cut his Legs when captured by Mr. 3? How he posed for his Death?
What he said about Shinigami in Arlong Park Arc?
How Arlong reacted to his Scar? Nothing Happened Moment?
His Fight against Mr. 1? His struggle with Enma?
How he challenged the Sword he bought in Loguetown?
Asura always being used when he is close to his limits & could die?
Dozens of Cross & Trinity References that are reference to Christian Beliefs?
The names of his Attacks based on Hindiusm?
Zoro's entire Story has been leading to this moment where he have to finally face Death
Just like Joy is Luffy's Theme which lead him to becoming Sun God Moment & Sanji's Theme being Heroism which led to his Germa Story
This is finally the Arc that gives a Conclusion to Zoro's Sub-Plot with Death
You think it's coincidence that Kaidou says "Death is what completes a Man/Warrior"?
You think it's coincidence that Death is heavily explored in Samurai's Culture?
The first Scene of Wano Arc was literally Zoro going to commit Seppuku
These are Major Sub-Plots, not just Zoro injured & then Chopper heals him
Oda could have done that with just Zoro vs King, no need for Hakai, Shinigami, Mink's Médecine, Bushido, Franky carrying him ... etc
