Most of the Robins from DC have been ruined for me because of a specific brand of fans. constant loud demands for more content of them on any offical dc post, endless discourse they flood online spaces with, don't even get me started on how many times we've been treated like we suffocate infants for fun after even breathing a non-negative emotion in the Jokers direction.

i don't really dislike any characters, it's more so i don't care about them. but i don't care about sword from phighting, i just never really got attached to him

other way around, I quite like Mr. Lopee but I don't see anyone talk about him. : (

Lots of "moe" female characters in anime are in this category for me. It seems that in trying to overload the viewer with cuteness the writers often forget to give a character any agency or significance in the plot. The epitome of this is Mayuri from Steins;Gate, who seems to only exist to get saved by Rintaro a few times. I guess for some people, cute character design is enough, but not me.

I find it rare that I dislike a character, I'm quite sure I have one in my noggin somewhere... Gimme a second; ....

Okay maybe I'm not a huge fan Minamoto Teru from TBHK, because of how he shows little to no interest of understanding Hanako-kun and would rather go straight to exorcise the spirit/ghost. Otherwise, in a positive light, that just means he's not naive or gullible like Yashiro Nene or his younger brother Minamoto Kou.
