try shingetsutan tsukihime the main character looks pretty weak

4. Idiotic protagonists.
5. Over-the-line rude protagonists.

Hayate the Combat Butler? 1st manga that comes to mind..

D'oh!

Tiji-kun!, I guess.

There are plenty of characters like that in One Piece, Luffy for one, looks like a wimp but he is very, i mean veeeeeeery strong and so are most of his crew.

I think Ryuuroden might also fits the bill and maybe this one too Blood Lad.

You like the things that i HATE, and i HATE the things that you like

Gokusen

Tower of god sort of.
