Sanji vs Doffy
Tanked his NAMED attack and continued to fight him.
Doffy calls him strong and uses parasyte, the same move that made Diamond Jozu immobile (3rd YC lvl) arguably a person stronger than Doffy.
Doffy resorted to parasyte against Luffy only after Luffy proved himself with G4. Up until then he called him weakling.
Doffy can no diff all of Zolo's NW opponents at the same time. That's the difference in power between their opponents.
Zolo vs Nerfed Killer
Gets hit by hakiless, nameless, not his usual weapons, nerfed Killers attack and faints.
Doffy>>>>>>>Killer
Sanji&Luffy vs Big Mom
Sanji matched 50% of Big Mom punch power. We know Yonko can one shot someone commander lvl with one punch.
While Zolo and Tashigi fight against Monet in 2v1 xd
