can you guys recommend some manga with op main characters

Onepunch Man
Berserk
Mob Psycho 100

noblesse

my favourite overpowered MCs are from web novel so...
anyways, in manga aside from saitama http://www.mangago.me/read-manga/onepunch_man/ I also like jin is also great http://www.mangago.me/read-manga/the_god_of_high_school/

thx guys but, I've read all of these already lol

Tales of demons and Gods. Moonlit journey across the land.
Actually most reincarnation stories of transported to another world stories.

you didn't mentioned so I just assumed you don't read much action manga. so you want non well-known ones? I read from Chinese to Korean to Japanese manga/webtoon so this will be from those. Other than my number one, (my above comment) these are my other personal favourites. note: I read ecchi.
