The strongests on the SHs side are Luffy, Yamato and Zoro.
Yamato and Zoro are very strong but they barely have some stats on real Yonko territory for now. They're both really below that level, so at most I would say the can work together to hold back Blackbeard or Mihawk. I'd say they better face Mihawk because Blackbeard is a hard, hard counter for zoans.
- Yamato and Zoro vs Mihawk. I don't think they can win, but they may last depending on the mood of the fight. Mihawk wins sooner or later.
- Luffy vs Blackbeard. With CoC and apparently enough level to fight and defeat Kaido in a fight, Luffy must certainly be strong enough to engage and perhaps defeat Blackbeard in a 1vs1 already. Blackbeard may deactivate Luffy's fruit but if he deactivates Luffy's fruit when Luffy is hitting with a G4 punch, Blackbeard is still taking the blunt damage anyway.
The Yami Yami no Mi isn't really special other than for that and on top of it, it makes Blackbeard take more damage than he would without it, and I think the gomu gomu may counter the gura gura?
I see Luffy actually taking Blackbeard down as he is now. But since Blackbeard is still resilient and strong it won't be a short fight. He may also have tricks up his sleeve.
The next strongest Shichibukai is Hancock. Since Sanji is out of the question, Jinbe should fight her.
- Jinbe vs Hancock. The whole fight depends on where does it take place. Both are great martial artists but Hancock's hax is strong as hell. I guess it should be possible to somewhat defend against with haki like BM and Kaido defended against Law, but Jinbe is not as strong as them.
If they fight near a body of water, I give the win to Jinbe who can jiujitsu some tsunami on her ass. If the fight is far from the ocean, Hancock is winning this.
So no clear winner.
- Sanji vs Doflamingo. Sanji isn't one for sharing fights and there's no SH remaining that could help him much against Doflamingo so I'll just go with a 1vs1.
Pirate Queen brought some fair points as to why Doflamingo would win, but at the very least Sanji could entertain Doflamingo for a while. I think I'll still put my money on Sanji on this fight: G4, which was required to defeat Doflamingo, was much faster and stronger than any SH at the time, but high YC opponents since them have all been shown to be capable of engaging G4 in a fight for one reason or another, so I believe both Zoro and Sanji must have catched up with G4's power as it was on Dressrosa. I know it makes little sense but that's just how this shonen works with the SH's leveling up between arcs and Zoro and Sanji are about to defeat YC1 and 2 opponents now.
It's true that Doflamingo was wounded (and thus nerfed) against Luffy but I don't believe he's YC2 as much as I love him.
And now I have a problem because I wasted ever CoA-user strawhat and I didn't match Crocodile yet... but the people I have matched needed to be matched there to defeat or hold the strongest Shichibukais.
Well, for now:
- Franky, Nami and Chopper vs Px0. Just like Zoro vs Mihawk, Luffy vs Blackbeard, Robin vs Crocodile and Brook vs Moria, Franky vs Px0 is a must for personal reasons. Franky rebuilt himself using Vegapunk technology from some abandoned lab of his during the timeskip.
As a Cyborg, current Franky is mostly superior to an old model Pacifista like Kuma, but Kuma has some sweet, sweet DF that can stop any attack from Franky in its tracks. Franky's attacks, be it sword strikes or laser beams, are all very straightforward and easy to predict, so Kuma won't have a problem with them. Aggressively, Kuma may also be Franky's superior thanks to his DF and Kizaru's beam. Kuma also doesn't run out of energy as easily as Franky does.
If this was a 1vs1, the fight would be long but Franky would go down for sure. I threw Chopper in because he's both a tanky character (in Monster and Guard Point) who's also very agile and versatile, perfect to keep some of Kuma's attention off of Franky without risking going down too easily. He may also injure Kuma with his Arm Point, I don't remember what's Arm Point's best feat so I'm unsure about that.
Anyway, Nami is the main player here. In this scenario, Kuma has to deal with Chopper, who would annoy him to no end, and with Franky, who may actually defeat Kuma if he manages to get a good attack in. Nami would have an easy time hitting Kuma amidst that battle with Zeus and unless the manga tells us otherwise in the future, lightning should be a hard counter for a cyborg. Especially such strong lightning.
Px0 goes down here.
Now, assuming the fighting doesn't take place in the Florian Triangle and assuming Moria doesn't spend a whole decade or two preparing shadows for Shadow Asgard, he's a weakling, just like Doflamingo made clear on Marineford.
- Brook vs Moria. Brook wins. Nothing else to add there.
This leaves...
- Robin and Usopp vs Crocodile. Robin and Usopp lack CoA as far as I remember, so... sorry for not coming up with a more entertaining matchup but Crocodile is beating them both.
She wouldn't be so useful if the SHs didn't outnumber the Shichibukai but she's just too good when she has allies.
