Luffy vs Kaido results: Luffy used all his forms while using G5 twice, pretty much for entire long Wano arc, all of luffys fights was just with Kaido and some other henchman not worth noting.
Vegapunk arc.
Luffy uses G5 and kicks Luccis ass, Zoro kicks Kakus ass.
Kaku, Lucci, G4 Luffy and Zoro vs seraphim Mihawk and Kuma, how those 2 got their ass kicked in what way is debatable but the results was that the entire strawhat crew looks all bruised up with bandages with Robin and Kaku getting the short end of the stick. Assuming seraphim Hancock did serious damage to rest of crew besides seraphim mihawk and Kuma but was immediately subdued by luffy.
Sanji assumingly solos Seraphim Jimbei no idea how he kicked his ass between regular flames or blue flames. Probably the only one without bandages but bruises from the last few chapters I saw.
Luffy uses G4 against Kizaru doesnt work out like it did with the Seraphim he fought and then uses G5.
We really can't power scale admirals to yonkos yet if we have to wait 2 weeks again.
