Who is your favorite "not batman" Batman?

Never really got a Batman vibe from the Duck Avenger.

Moon Knight is a lot more of a The Shadow expy than a Batman one. To the point of playing with multiple personae / aliases and what they know about each other, or seem to know, and having a definite love interest who's in a perpetual conflict because of his vigilantism (Marlene / Margo).

Both Moon Knight and Batman are in debt with The Shadow.

That being said, well, Moony is my favourite not-Batman outside of the batfam.
I also like what I've heard or read of The Shadow and here I've just remembered that serial in Fallout 4 that was a really fun knock-off of him (I loved that quest).
Daredevil too, is a character I enjoy a lot; but he doesn't have a lot in common with Batman, so I don't know if Matt really counts.

Ah, and Hei from the anime show Darker than Black.
EDIT: oh, right! Person of Interest too was a lot batman-esque. But the character that I really liked out of the leads was Finch, who was more of a Sherlock than a Bruce.
