anti-hero, in the choice The horrible, mean, & bad attitude one

They could be dense/air-headed with regard to daily life/social situations but be geniuses otherwise (eg. Rukawa in Slam Dunk!, L from Death Note, Tamaki from Ouran High School Host Club, possibly also Tsukasa from Tokyo Crazy Paradise...)

Mine is quite complex : for a male, it would be a mean one with horrible attitude towards everyone, but his way of acting would actually be in good intentions. He would be cold to anyone.

For a female, in can't choose at all, Iike a lot of types here.

If anything, I'll be grey.

My favourite type of character (male) is the hyperactive but cool and funny one. Though they might come off as lame to the other characters. Somewhat like Yuki's brother from Fruits Basket or Tamaki from Ouran.
My (female) favourite is the serious and calm one that can surprise you with anything. Like Hotaru from Gakuen Alice or Takano from School Rumble.

The helpful, kind, and cool ones. They're just so helpful, kind, and cool!

Like Youko

Where's the "funny, laidback and down-to-earth" type

From the list i went with The quiet, stoic, even tough i don't really care about the good looking part, but my favourite one would be a Wrathful character, maybe emotionless most of the time but snapping for almost nothing and going on a rampage.

We don't have enough mad characters on manga.
