Don Le Fishe will fight you!! No idea who's Yamatos but there isn't a character in this manga named Yamatos and that's a fact!!! You can't be a woman of you don't exist!!!!
Now, prepare for a FISH SLAP!!!!!
I'm just assuming you're being sarcastic, hence the like xD
But since other people read in here as well I'll answer the question anyway :)
Right off the top of my hat, I'd say that whatever hype last chapter were trying to build with the reveal of giant dragon momo got completely derailed in this chapter for the sake of comedy, even though it really wasn't all that funny
Luffy was always able to go in and out of G4. It's just that when he overuses his haki by staying in G4 too long he's unable to go back into G4 because G4 is the combination of his haki and his devil fruit power.
All of his relationships seem to be on the violent side. Big mom is the closest thing that he has of a friend and they fought for 2 days until they decided to stop until they conquered the world, then they would resume it until one of then died I dont think Kaido is full blown racist but he definitely prefers to keep his distance
