Df is a random robot going to do when you got a flashback saying that Nika will liberate both Bonney and Kuma
Kizaru will face Zoro if he comes back given how one Luffy punch was sufficient to take him down
Lucci will be taken care by Sanji
Star Gun is never landing again, that move requires buildup and Kizaru knows the effects. You got the Kizaru fight wrong, it was never going to be about AP, Luffy high end attacks were always going to hurt him
badly considering he’s a speed based logia and not a mythical zoan brawler. If Oda doesn’t want make Kaido a fraud, his durability and Kizaru’s durability shouldn’t even be comparable, same tier or not.
The difficulty was always about landing powerful attacks clean, Luffy had to push himself to the limit of his G5 that made him completely vulnerable afterward, unable to even pump himself to land one against a Kizaru that was more focused on chasing Vegapunk.
in a hypothetical round 2, Kizaru would be focused on Luffy, making it much harder and maybe forcing Luffy to start developing new speed based moves
