Who's a character you love that gets a lot of hate?

Sasuke Uchiha.

Lucy Heartfilia from Fairy Tail. She gets hated on for the worst reasons. For example, she dresses like a "slut", that she's shipped with many guys, that she gets in the way of a certain ship, for stealing a fan's fictional husband despite her not having any romantic feelings towards that character and nor is he (the fan's fictional "husband" ) actually that fan's husband.
Now another reason she gets hated is because she's so weak. Now, considering how far the series progressed you can see how she's getting stronger. (I.E the recent episodes, especially the one where she fought Jackal).
I used to dislike her actually, but by rewatching the anime and starting the manga, I grew to love her.

Kaname Kuran from Vampire Knight. He's mostly just bashed because he's not Zero.

Practically every one of my favorite characters are hated immensely for whatever possible or illogical reason.

An example would be Orihime Inoue or Nami from One Piece. Almost every female character in anime get too much hate and sometimes the males. It's ridiculous.

Francis "France" Bonnefoy

Hetalia

I really love Claude Faustus from Black Butler. I love villians and I'm a sucker for dark hair and glasses. Everyone says he's evil and cold hearted, but that's cause HE"S A DEMON. He is supposed to be that way.

Matou Shinji
Guy did nothing wrong

Misty from Pokemon So many people hate her even though she is beautiful and kind

Alphonse Elric from Fullmeatal Alchemist
Eveyone ignores him cause of his brother Edward even though he's so sweet.

Sosuke Aizen (Bleach)

There are a few characters. Unfortunately, quite a lot of people hate just for the sake of doing so. To that end, their reasons range from whatever idiotic comes first into their minds to copied opinions of others without any need of procession.

One character that I really love and usually see getting a lot of hate is Medaka Kurokami from Medaka Box. Honestly, many consider her just a Mary Sue and point out her looks as the only reason to be drawn to that character. First of all, I never believed in terms like that. There is no such thing as one being ultimately perfect. Being considered like that is an imperfection in itself. Besides, a character's strong point might be considered a flaw from another person's point of view. Opinions vary. She's a talented and charismatic person, to the point where she has given the impression of being a perfect being (and in a pretty comedic way most of the time) but the reality of it differs if you decide to look past the surface. She has her own issues to face and struggles with them as the story progresses. Second, when it comes to her looks, just like a lot of characters that are getting bashed for that reason alone, keep in mind that one's appearance does not define the character. Hell, if you really think this girl's boobs are TOO big then you probably haven't seen any Ecchi or any other Shōnen series. As someone who has, I can tell that they are actually moderate.
Anyway, I find Medaka Kurokami to be a great character and she's much more than meets the eye. The same goes for the Medaka Box series as a whole. If you take a closer look and not just stick to first impressions, it will be easy to understand what I mean !!!!

People treat Todomatsu like trash just because it was the fandom's fault for starting the theory that made everyone hate him. The theory is that "TODOMATSU IS THE DEVIL"

There are tons of differences between the real devil and Totty dude! Don't just start a rumor that is not even true like they did to Charlotte from Making Fiends.
Making Fiends isn't an anime, it's a NickToons show, but I just had to add that!

I know the anime states that Todomatsu has no heart. But it just means he's immortal, not the devil.
And he just gets mad. It does NOOOOT, at all, make him the devil.
This theory just triggers me, and Todomatsu is my flipping anime crush which makes me MORE triggered ;w;
