barely
Having bandages =/= that heavily nerfed.
Aramaki gave them 7 days of rest. People in this manga recover from fights in couple of days.
Luffy was literally was fine after Katakuri blowing his stomach out few days later without a scratch. Hell, he even recovered after Kaido's beating few minutes later by just eating some food.
Definitely not more injured than Zoro and Luffy.
They were not thrown into prison. They got there on their own.
King and Queen were the only beast pirates that escaped Onigashima and they regrouped in Queen's territory- Udon. They were literally partying before Aramaki came in.
Not a big deal.
He can pick up another sword and his base wings served no purpose in combat anyway. He can literally transform into a hybrid zoan that gets wings AND can act as his swords.
Shanks said winners were nerfed though. So imagine the losers, they should be even more nerfed.
But yeah, you're right that they weren't more injured than Luffy and Zoro though. Still, Shanks was talking about the allies as a whole, when he said they are nerfed. It wasn't just Luffy/Zoro
And again, they got high quality medical assistance for a week.
Queen loses some germa tech and lasers from losing his arm.
King lost his sword. You can't just pick up a sword randomly lol, that sword was something King personalized for his usage.
Yeah, King's hybrid form can somewhat replicate swordsmanship. But, King's strongest fire attacks are channeled through his sword. He has consistently use his sword for this.
Another factor is also that King's main drive/dream was to make Kaido PK. After Kaido's loss, and we not even knowing if he's still alive, that would be a big hit on King's motivation/will.
I think King can put up a decent fight against an admiral if he's at full health. Say a low-mid diff. Just seeing how Marco fared against admirals too, in Marineford.
But it's also possible that Greenbull is the one admiral who can no diff King due to matchup. King's greatest asset is his durability, and Greenbull is capable of negating that
