Considering you nominated Robin for most underrated character as well as this category, I guess you're on of the people underrating her?1) Eustass Kidd:
Thank you, Kaido. What a nuinsance this guy is.
2) Vinsmoke Sanji:
Just what i expected from this character, crying in a room for being powerless.
3) Nico Robin:
Uhh, i get she's the counterpart of the Sunny's mood but still don't find her interesting. Don't like her personality most of all.
The Sanji thing is exactly what I did not expect from his character. Used to be one of my favorite characters, now... Well, wouldn't say least favorite because there are too many good moments in the past, but if "Whole Cake Arc Sanji" could be nominated, he'd be my choice.
Kidd is meh, I agree.
