In my honest opinion (and obviously with some bias), there are reasons why I wholeheartedly believe this is the true order:
- Kizaru + VA's
- Elbaf's villain group
- Blackbeard + Akainu
- Shanks + Mihawk
- Imu + Gorosei
Objectively, the first 2 are true. Kizaru is evidently the main aggressor in Egghead and Oda has dished out the lineup of marines assaulting the island. Elbaf is confirmed to be the next island, so if Kizaru falls here and none of the others on the list are tied to Elbaf, then it stands to assume that Elbaf has it's own problems (be it God Elbaf, Loki, Rocks, Burned Man, Underworld, Level 6 Pirates, you name it). This is objectively separate from the other groups here obviously.
Then it comes to the big controversy that is the 4 Yonko and Akainu. Note I am using Mihawk in place of Buggy here, because for all intents and purposes, Mihawk is the reason Buggy is a Yonko (we all know this). So whether or not it's all of CG that survives or just Mihawk, know that I personally consider them the same thing. So the first thing I want to bring up is relationships.
- The Marines intend to fight the RHP at some point (Ryokugyuu says this)
- Shanks and Blackbeard are fated at some point to clash
- All 4 Yonko are going after One Piece, and by virtue, the 4th RP
- Shanks and Mihawk, like Shanks and Blackbeard have unexplored history as well.
- Zoro and Mihawks obvious fated clash
- Luffy's personal beef with Akainu and Blackbeard, as well as wholehearted intent on meeting Shanks.
Assuming the 4th Poneglyph/Burned Man is the focused plot after Elbaf, then it stands to reason that Blackbeard, Akainu, Shanks and Mihawk will all be involved with Luffy here, culminating into a bigger conflict. Now, you might be asking, "why Akainu?, he's a marine". And my answer is truly Mihawk and Fujitora, because IMO, Zoro will become the WSS at the same time Luffy becomes PK (or right before).
- If Kizaru loses here, then that means there are only 2 Admirals left for Zoro and Sanji to face. Its obvious who they "should" match up with. One is calm swordsman (like 90% of Zoro fights), the other is an extreme pervert or ladies man like Mr. 2, Absalom, Queen, etc. Do the math.
- The one obviously being a Swordman, is technically rated a 3 billion berri bounty like every other Admiral (I know I know, we can't "scale" bounties, but we totally can since Oda does this anyway such as making a big deal about Katakuri's billion bounty coinciding with strength). This is in fact, lower than Mihawk's, who IS the WSS.
- If the Admirals are 3 crowns, it makes sense that Akainu (scaled in crowns) is probably 4, or 4 billion berries, so basically relative to Blackbeard's 3.996 Billion and Shanks 4.0489 Billion by being right in the middle.
- Discounting Kuzan (whom I think won't be anyone's fight save for Luffy or Koby), Shiryu IMO seems sort of relative to Admirals in portrayal, so I would expect between a 2-3 billion range for him.
- If the Zoro fanbase thinks about this logically, how would they scale Zoro facing Shiryu, Fuji and Mihawk then altogether? Shouldn't Shiryu and Fuji (in no particular order) come before Mihawk if all logic is followed in regards to the WSS here being faced last?
- Remaining pointers to Akainu and Blackbeard falling together are outlined here in my other thread:
(3) Future Events - Akainu and Blackbeard are destined to lose together | Worstgen
- If you are going to use the Strawhat Fleet for any conflict, Luffy being at his biggest in terms of leading a specifically pirate army (not talking about against the WG) should be against the Marines and/or Blackbeard, since each have multiple divisions and fleets. Shanks' fleet is notoriously week, and technically wouldn't play a role.
- Finally, Luffy surpassing the Fleet Admiral does not seem to a role that should be carried "post" PK. The Pirate King is a direct effort trying to be prevented by Imu, so I feel the FA already fails their purpose as Marines. if they even allow anyone to become PK in the first place.
We aren't entirely sure if Blackbeards bounty will move again, but lets assume nothing changes from this point forward with any of them. You have, what could be, a more direct order of how things may end:
- Blackbeard: 3.996 Billion
- Akainu: 4 Billion (assumed)
- Shanks: 4.0489 Billion
Now the only reason I put Shanks and Mihawk after Akainu and Blackbeard is because Shanks' actual relevance and importance to Luffy and the plot of this story, it's not necessarily a powerscale. The "Straw Hat" essentially signifies the journey at its end and the means to surpass Shanks officially, who essentially is the living incarnation/measurement of Roger (both in evidently Haki and Fighting Prowess). I believe Shanks and his crew will survive the events of the 4th RP, and along with Mihawk, will face Luffy and crew at Laugh Tale. Not only this, but the when consider Benn Beckman, he's another "ladies man" who's not a swordsman, though far less eccentric than Ryo or Queen, etc. And IMO, Mihawk will take the role of Zoro's fight here while Sanji ends up fighting Beckman.
Finally, I place Imu and his Gorosei last with the assumption that they reside at the pinnacle of the world, even gearing us for the idea that someone like V. Nasu has other qualities that can allow him to surpass someone like Mihawk in terms of endgame strength for Zoro. But we need to see how Saturn is used in this arc to make a better estimation on how strong he is relative an Admiral in the same arc (if we even can make that estimation).
Note that at this time I do think that Imu and the WG may end up traveling to the end of GL on their flying ancient weapon, which I think is God Valley. I actually even wonder if Fuji could just bring New Marineford to the end of GL..... After all, according to Oda, the series does in fact end when One Piece is found so maybe it is justified that everyone is far closer to LT than us going backwards.
And yes, sure, there are plenty of caveats to all of this. This is just my opinion.
tldr:
- Kizaru @ Egghead
- X Villain @ Elbaf
- Blackbeard and Akainu @ Lodestar and/or New Marineford (transported by Fuji to the end of GL lol)
- Shanks and Mihawk @ Laugh Tale
- Imu and Gorosei @ God Valley
