It would be pretty wild for a character meant to embody the negative aspects of Luffy to not be beaten by Luffy.
While teach and shanks have obviously been relevant longer and are in general more important the same can be said about Linlin and kaido
Linlin having tons of parallels with luffy with their beef even predating the other. Idk I just don’t think it’s too crazy to believe luffy will focus on 1 emperor while the other goes down to relevant allied characters
If it’s between who’s more important between shanks and Blackbeard I think shanks is the clear winner
I will say this tho…
Even tho it’s another unpopular opinion I still would love to see luffy vs big mom potentially in elbaf. If Linlin does end up returning again and stronger and better than ever with her actually being allowed to be competent and go all out I wouldn’t have a problem with it lol. Especially with how much build up luffy vs Linlin got
I say that to say I also wouldn’t really mind if something similar to that happened to Blackbeard. Like let’s say current Blackbeard looses to someone besides luffy but returns stronger than ever with 3 devil fruits and fights luffy
