One of the biggest controversies in the fandom about One Piece is how weak Buggy is compared to how he should be as a former member of the Roger Pirates as well as crewmates with Shanks.
I think Buggy's weakness makes sense cuz he describes his time as part of that crew as traumatic, which left him paralyzed in the East Blue, unwilling to seek further ambition in the GrandLine. His fallout with Shanks also explains it as he originally wanted to get the One Piece with Shanks but Shanks didn't want to and so he lost his will.
In terms of fighting, it makes sense that he didn't get that strong because he probably never had to fight crazy strong characters since he was in Roger's crew and he prolly played the same role that Ussop, Chopper and Nami play in the dynamic with the Monster Trio. His lack of Haki comes with the fact that he lost his willpower, first from the death of Roger and his fallout with Shanks and he had never needed to learn it before cuz the other crewmates on his ship took care of the DF users and strong members whilst Buggy and Shanks prolly fought the weaker ones or teens/children like them(Marco and Blackbeard in the case of WB pirates).
I think the chapter in which we saw Buggy proclaim his desire to find the One Piece is prolly him getting his willpower back and maybe he will get Haki now but Oda might not give it to him cuz of the meme. What u guys think?
