If this is from the current arc each of these figures are respectively from then Luffy would probably beat:
- Hachi and Kuroobi
- Ryuma and Absalom
- And Luffy by the end of Wano could beat King and Queen
- Alabasta Luffy would lose to Mr. 1 and Bonclay (Mr. 1 would have high resistance to impact based attacks and slashing would be a weakness to Luffy and Bonclay could easily trick Luffy)
- lose to Kaku and Jabra (Luffy grew a lot during Ennies Lobby but needed 1v1 fights in order to grow and try out new techniques)
- the most obvious loss to me would be Vergo and Pica because of Pica's insane ability and Vergo's insane haki
