Eiichiro Oden - I have rarely seen an author try so hard to make their character tHE BestESt EvAr.
Momo - “he will eventually become the greatest Shogun ever.” Sure thing Oda.
The rest of the Wano populace - they made me actively root for Kaido or the WG to turn their entire country to ash, yet Oda keeps trying to convince us they’re likable and sympathetic.
Yamato - maybe not as bad as her role model, but I definitely felt like Oda was trying too hard to make her a star, if only because of her insufferable Oden cosplayer gag.
Luffy - Oda has gone full throttle making him the Chosen One who will bring sunshine, gumdrops, and rainbows to the poor suppressed people of the world, right down to egregiously retconning his DF into a god Zoan that the Gorosei kind of forgot about for the entire franchise.
