hi im looking for some manga or novel whit cool mc like ayzen in bleach or Kumagawa on medaka box or sun in the legend of the sun knight

Could you be more specific on what "cool" means?

well look at ayzen for example
he pretend to be good bud was the bad guy , also he doesnt power up cause friendship or some bullshit like those and also he was strong and from start was powerful
or kumagawa he was emotionless and on top off that he never was a winner or have friend but he was strong and do whatever he like
or sun , he care about his friends but he never get stronger for them, he lost something for them but he never get stronger cause of them and also he was insane cruel and so many other thing but he never do stupid thing like go against an army or a god or the strongest creature whit the power of love or friendship and in the end whit some kind of nonsense like "i can do it" or "i most do it because people how belief on me" win against them. he make scheme so he can take his enemy down whit whatever it take

is it enough?

There's Durarara!!, manga and light novel (and anime). It has multiple protagonists and they're all rather twisted.

Utsuro no Hako to Zero no Maria (Novel) is another one. The protagonist doesn't quite fit your explanation, but there's an anti-hero type character in it who's pretty unscrupulous.

Then there's Code Geass. I don't know how the manga holds up compared to the anime, but it's definitely something you shouldn't miss.

Darker than Black is also based on an anime, but the MC is such a badass! You should give it a shot.

Do you only want shounen or are you interested in shoujo too?

Arifureta Shokugyou de Sekai Saikyou (Novel) Nagumo-kun will fit what you're looking for i think (after the first few chapters)
