1. Luffy
2. Zoro
3. Kid
4. Law
5. Drake
6. Bonney
7. Bege
8/9/10. Killer/Hawkins/Apoo
11. Urouge
Luffy and Zoro are obvious. Oda always had plans for Kid, unlike the other SN, so he should be the next in line. Law is pretty obvious. Drake will be one of the leaders of the reformed Marines. Bonney will almost certainly play a fairly important role in a later arc, given her DF ability and mystery around her, and she could be higher than Drake. Bege was a key player in WCI arc. Killer/Hawkins/Apoo aren’t that relevant to the story of Wano so far. Urouge could maybe get an important role in a later arc, but I doubt it.
