I'm looking for something like Kuroko no Basket or Shijou Saikyou no Deshi Kenichi, where there's a group of really strong guys(doesn't matter in what), and they appear and are deafeated by the main character one by one.
Not looking for anything specific other than that, it can be a sport manga, fight manga, anything really..

Dear Boys, I'll, maybe? Idk, do you want the super-talented already or the "let's reach the top with team work"?

Either is fine, but If I had to choose, it'd be a plus if the main character already starts strong or talented
