What is the most annoying personality trait/trope of a character?

Same here, I really really hate clingy アニメ girls that can't take hints, like seriously jeez.

As for what u 発言しました in ur 質問 intro, I couldn't have 発言しました it better myself xD. Clingy characters are the death a real romance and they just seem desperate.

As far as romance goes, I prefer characters that are もっと見る natural and ridiculously less obvious and that have personality.

(PS: the picture 投稿されました is from the アニメ called "Say I 愛 You", it's very sweet and I wish all romance アニメ were similar to it, xD)

The typical Mainstream Shounen MC like Naruto, Luffy and Natsu
These types of main characters are so cliched that I just frown seeing them time after time again -_-

The whole main female character hitting either the MC または the other characters for comedy purposes. Like literally, it's in FT, Naruto, 犬夜叉 and other shounen anime. It's not funny and it's so annoying especially when it's over a silly reason.

1.Whiny (like Shinji from NGE and Yuki from Mirai Nikki)
2. Characters hitting other characters for no reason. (Alot of times I can deal with it and sometimes the characters actually deserved it. BUT there are sometimes they go overboard with hitting that character. It's like why would あなた do that.
3.I dislike when some character perceive it's their duty to do something but in all actuality. 発言しました thing wasn't needed at all. Some characters are overly committed.
4.Self-pity. (this kinda goes in with the whiny and yet not) People who constantly say I am not strong enough when it reality they are much stronger than they think. It's so annoying to me.
5.Clinginess for me as well.'
6.sexist characters

I am pretty sure other types would come to mind but as of right now I cannot think of others.

Okay, I'm prepared for the hate. But I'm about to be brutally honest.

EXTREMELY SHY, SOFT-SPOKEN, AND WEAK-WILLED 'CINNAMON ROLLS' ARE MY BIGGEST PET-PEEVE IN ANIME.

These types of characters are mainly found among female characters, and unfortunately, many, many of the 'bottom' characters in yaoi. And these characters just make me want to DRIVE A SCREW-DRIVER INTO MY EYE (excuse the gore, please).

They're so weak-willed, and always do nothing but whine または hesitate. Like, get a freaking 移動する on! You're not being cute, you're being annoying! And I hate it even もっと見る when they only exist in the アニメ to obsess the main character! または some other main 愛 interest! It's annoying!

Now, there are the types of cinnamon rolls that are similar. They are, too, cowardly, hesitant, doubtful, etc. Except there's one big difference... THEY HAVE CHARACTER DEVELOPMENT. THEY LEARN TO NOT ONLY OPEN UP TO OTHERS, BUT TO 愛 THEMSELVES. TO EMBRACE THEMSELVES. To stop being such a pitiful thing, and get a freaking grip!

And honestly, I mainly don't like these kinds of characters due to the fact that they're always being taken advantage of によって not only others, but the main character himself/herself. Manipulating feelings または actions should not be glorified... ever!!

Tsundere characters. Nuff said.

characters that are too perfect and flawless. they are good in everything and this type of character tend to annoy me all the time it makes me want to スマック my computer screen

Clingy is annoying >_> But what I hate is characters that are tsundere just for the sake of having a tsundere character in the show. They have no character arc whatsoever. Don't get me wrong, I really like tsunderes, but not when they are this generic and annoying ~

Houki Shinonono from Infinite Stratos is a perfect example

1. Male Tsunderes.

2. Genki girls.

3. Dudebro badasses.
