Another problem with this chapter is we’ve seen Kaido get knocked around so much that Luffy’s actions this chapter don’t have much of an impact.
G2 first use- shit stomps Blueno. Up until then, CP9 had been amazingly strong. It’s a huge “the tables have turned“ moment.
G3 first use- gigantic ass punch that nearly knocks Lucci clean out. Not quite as impactful as G2‘s first use, but still has an oomph factor.
G4 (Bounceman)- Luffy goes from struggling horribly against Doffy to knocking him around Dressrosa like a football. It‘s a huge moment
G4 (Tankman)- I think the weakest one impactwise but it still does let him take down Cracker immediately.
G4 (Snakeman)- another strong first impression, gives him the upper hand on Katakuri, Katakuri doesn’t have a clue what’s happening.
Here, we see Luffy toss Kaido about with ease…
… but we‘ve already seen that. The first use of G4 was battering Kaido around and everyone was watching in amazement.
I’d actually say that the G4 moment looks more impressive than G5, becayse that’s the first time we ever actually saw someone really take the fight to and dominate Kaido, plus it had Big Mom and the Worst Gen all watching in amazement.
