Kid is a top 20 character, Shanks is barely above him in popularity but Oda didn’t care about the optics for Kidd in that moment. So it doesn’t matter that much.
The planned narrative will hold more weight, and Kidd’s narrative isn’t finished. He will come back as one of the strongest characters since he‘s a new gen leader. Law already alluded to what’s coming all the way back in Punk Hazard.
Kidd, Law and Luffy literally changed the course of history by beating Kaido/BM. All of that buildup won’t head to nothing imo. That was just the start of their legend.
