He can level an island. Can Vergo do that? Nope
His punch can destroy a town. Can Vergo do that? Nope
His arm rock was fast enough to grab Luffy, Kyros, Law, Viola and the king sending them outside of the palace. Could Vergo do that? Nope
He has damage immunity and regeneration. Vergo has that? Nope
Did Pica level an island ? Nope, it was just the palace.
Does this matter in any way for this thread, nope. because that skill is totally useless in a fight.
This kind of argumentation is just so childish and subjective. I can make a list ten times longer with the skill Vergo has over Pica such as Soru, geppou, ranged attacks, haki etc. But it doesn't matter.
What matters is that Pica's stone shell was and is absolutely useless against strong fighters.
Don chinjao blew an arm of together with the king of prodence on half power;
Luffy blew his head of in a single blow;
Zoro is slicing through stone as he is cutting paper.
Do you think Vergo isn't able to do that in his massive haki mode with that kind of destructive power that he shown ? nop... oh wait a minute YES OF COURSE !.
can you tell me what vergo can do when pica is in his giant rock body ? his attacks will be like a mosquito bite (attack on titans)
Vergo would kick the shit out of that weak shell, just like other musquitos like Don chinjao, king of prodence, Zoro and Luffy already did.
One on one with the real body it wouldn't be a fight it would be rape for Pica.
Questioning Pica vs Vergo is laughable at this point. The only question is:
Can Zoro (with the abilities from Punk Hazard) cut through Vergo's haki. If the answer is yes, he would probably win. If it's no he would obviously lose.
All the other bullshit doesn't even matter. Don't come with the crap that Zoro most likely can because he is Zoro. Cavendish already showed that you can't cut haki just like that. And Sabo broke a VA's sword by pinching it with only his hand covered in haki.
SO if you want to convince me, explain me HOW Zoro would cut through something like that, not on what diff or how long it takes him to solo. That is not interesting in a discussion, and a just an excuse to raise post count rather than joining a conversation.
