Lol, at what cost? Oda off panelled their fight and only showed how they one shot these two after Neko and Inu went sulong again.
And Jack's hybrid is, since Jack is officially defeated, is a very terrible lazy design.
Yeah that's the worst part
Oda offscreening the battle
All we got is that
sulong dukes >hybrid Jack/Pero>base dukes
Both parties need luck to win
Dukes need the moon to be visible to win whole Pero/Jack needs sulong to wear off in order to win
BTW Doffy isn't really above Calamities
He suffered same outcome vs G4... luck is how he survived round 1
He's a Joker who can be weak as Jack or strong as Kong.
