There's a lot of characters who are the opposite of who they are despite their physical appearance. Like Takasu Ryuuji in Toradora, who is actually a nice guy, even though most people take him as a delinquent based on how his eyes look. So I'm looking for main characters who are exactly what they appear: Characters who are scary-looking, who scare others on purpose. Dumb-looking characters, who are dumb.
Mita Mayo in Sayonara Zetsubou Sensei, is the perfect example: People disregard her appearance and treat her liike an ordinary girl, even with all the felonies she committed( like blowing up the school building).

I'm also looking for a character that is like Sawako Kuronuma in Kimi ni Todoke, but her personality is opposite of hers: she does not tries to make friends, she scares people on purpose, and does not care about anything, especially if someone close to her dies. But along the way, she starts to change her ways little by little by someone's influence or an external factor.

The Wallflower (whom I suppose is the very opposite of Sawako from KnT?)
