To be honest I'm not a big fan of Ulti but this is the most impressed I've been with a female character in a long time so props to Oda for making a female character looking like an actual threat for the time being.
Luffy was about to resort to G4 in a much shorter time against Ulti than he did against Cracker. And this wasn't because he was pressured for time or anything. He straight up said "such strong power". This means Luffy was acknowledging that Ulti was simply too strong to be beaten without G4.
The portrayal is clear, Ulti > G2/G3 Luffy with FS and ACOA.
Goddamn, I'm going to have so much fan when the chapter comes out.
Well yeah i guess if you are talking about female characters
But Oda still chickened out by making sure luffy never punches her he just suplexes and head butts her... which are moves very clearly weaker than an actual punch from him. .. Oda can't have the mc punch the shit out of her
