severe marco downplay imo.
he wasnt just doing superficial damage. that move was strong enough to send queen flying into the opposite building. if anything he was overpowering the both of them in those clashes at the same time while being nerfed.
at marineford, he was sending kizaru crashing into buildings, aokiji flying etc.
he also clashed with big mom albeit temporarily.
he is more than enough strong offensively to put them down. and there's also a possibility he'd go to the rooftop to fight kaido.
no. sanji isnt there yet.
the gorosei expected marco to become a yonko and to defeat blackbeard. do you see post wano sanji doing stuff like that?
shanks offered pre marineford marco a place on his crew. do you see post wano sanji getting such offers from shanks?
as i said, EoS sanji or even the sanji that's gonna fight in that war, surpasses marco. and that war is like 2-3 arcs away. but post wano? i dont think so.
for the record, i think post wano zoro is only slightly above marco (give or take) so you should see where im coming from.
Well like your example with Kizaru, sending characters flying doesn't necessarily equate with a lot of damage, and Marco wasn't able to do significant damage that would stick with the two.
The effect of his named moves basically got covered by the basic Ancient Zoan regen.
I think Marco has some stronger named moves, and i am relying on speculation to give Marco the benefit of the doubt due to his overall portrayal to pull through and be able to defeat either King or Queen in an extended battle, but it would take some degree of high difficulty to do so.
The Gorosei did not think of BB or Marco to be on Yonko level, and they brought up the possibility of Marco halting Blackbeard's attempts to conquer Whitebeard's territory with the help of the WB pirates and their allies. Also we know the outcome and it doesn't paint Marco in the light you think the Gorosei claim would.
I agree, Zoro will not be a lot stronger than Marco/Sanji, i think he will be on Benn's level. That means he would win for sure against either Marco or Sanji in a decisive battle, but he'd require a degree of high difficulty to do so.
Post Wano i think they will also be a bit stronger than you'd assume just from seeing their final fights, since they'd get to start out fresh, with all the growth they've experienced in this arc.
So that's why i have :
Luffy ~ Admiral level
Zoro ~ Benn level ( which is inbetween Marco/Admirals )
Sanji ~ Marco level
