 Likai:

Three come to mind already:

Beyond Evil
Vincenzo
Mouse

I have not seen Beyond Evil yet. I am planning to give it a watch. How is it?

Our Anti-hero in Mouse sure is one of a kind.

MOUSE is an amazing drama regardless of any tags. A must watch drama. 

 Luffy:

How is it?

I also haven't watched it yet.... But I don't here anything about it being badass & op. 

 shubham prasad:

Beyond evil.... Umm, badass & op??? 

Both the male leads are badass in their own way, but there are no martial arts action just action.

Partners For Justice kept me seriously Hooked for 2 seasons

My favs with badass ML:

- Mouse

- Rugal

- Bad Guys

- Memorist

- The Bridal Mask

How is the guardians? Is the ML a protagonist or an antagonist?
