This will be a match inspired by a pro-wrestling gauntlet match.

That means the two people start, and the winner of that match fights the next guy, and continues to fight until he loses. And then the guy who beat him goes on until he loses, and so on.

Their will be several Gauntlet matches here, and the competitors will be the big bads of each arc.

First up, the East Blue Saga Gauntlet

1. Iron Mace Alvida
2. Captain Morgan
3. Buggy the Clown
4. Captain Kuro
5. Don Krieg
6. Arlong

Second, the Paradise Gauntlet

1. Nefertari Vivi
2. Mr. 5
3. Mr. 3
4. Wapol
5. Crocodile
6. Bellamy the Hyena
7. Enel
8. Foxy
9. Rob Lucci
10. Gecko Moria
11. Kizaru
12. Boa Hancock
13. Magellen
14. Akainu

The New World Saga
1. Demalo Black
2. Hody Jones
3. Caesar Clown
4. Donquixote Doflamingo
5. Jack the Drought
6. Charlotte Katakuri

(Note: I am leaving Big Mom and Kaido off this match for the sake of having the winner be a question. Big Mom is obviously better than every other villain before her in the new world except Kaido, so ending and katakuri is my preference.)
