Luffy and his peers, Law and Kidd, beat two of the Yonkos in Wano. Luffy and his peer, Bonney, beat a Gorosei in Egghead.
And you naively mentioned Zoro and the Cook here to beat the Gorosei?
@HellBlazer04, we got another one.
Get this to your head: after over 25 years, not even Lolda thinks Zoro and the rest of Luffy's crew are important enough to beat the likes of the Yonkos and the Gorosei. The likes of Coby, Sabo Dragon, Law, Kidd, Momoron, and all other Luffy's peers will take more importance in helping Luffy beat Imu and the Gorosei than any of Luffy's crewmembers.
There's maybe 5% chance of Luffy's crew vs Admirals (and I'm being generous). The chance of Luffy's crew vs Gorosei is even lower (1%). Don't feel bad about it. That's just how Lolda wrote his story.
