1. Roger - I don’t think we’ve ever seen a bigger “expectations vs reality” type character than Roger. As much as I love as adventurous he was, he lost a lot of the aura that I expected of the “Pirate King.” I’m all for the fun loving, but this man was supposed to have “Wealth Fame and Power.” Meanwhile we never saw that. He’s strong, but we never saw him or even heard of him winning a fight. Just draws against Whitebeard and Shiki and nearly killing one another with Garp and Roger. I didn’t mind him begging for Oden, but I hate the idea that this fight hungry fun lover snuck through Big Moms territory for her poneglyph. Again I don’t hate the current Roger, but he’s not the man we were introduced to chapter 1.
2. Big Mom - Even with her ugly appearance she first seemed terrifying and her crew was impressive… for like half an arc. As soon as we saw the beast pirates the BMP looked silly in comparison and Big Mom turned into an actual meme where everyone had a turn to clown her. Imagine going into Wano and hearing “Big Moms actually just going to be a hype tool for King and Queen before getting beat by Kid Law and some bombs Kaido keeps in his basement.”
3. Country of Wano - This country was hyped for years and even concerned Sakazuki… then we see it. The country of samurai is so fraudulent the strongest samurai there aren’t even from fucking Wano, they’re minks. The entire country gets carried by Ryumas legend and Odens history with Roger and Whitebeard
