Before the Nika, liberator of the weak and oppressed shit, Luffy just had great timing when making land on an island to free them and Oda being an unoriginal hack.
But now, even that tiny little thread of suspense of disbelief that Luffy not being a lame ass destined hero archetype is gone and we got the Nika shit instead.
Even before Nika shit .
Luffy member of the D clan , a DF , Grand dad and father that are super strong ( this shonen that shit get pass one ).
Beating pirates that been around for decades at 17 , then we found out he had CoC which top tier guys have.
Then get train by ray for while , then get all advance version of haki and awaken his DF.
Even if DF was not nika all that shit is chose one for years in the manga .
Hell even WB talk about BB being wrong D was destined hero talk for luffy .
