Two of my favorite comics of the last 10 years are both police procedurals set in a super hero world:
Powers by Bendis and Oeming and
Top Ten (and spin-off Smax) by Moore, Ha, and Cannon.
I just recently notice a major parallel between the two. Take a look at two sets of detective partners.
Deena Pilgrim and Christian Walker from Powers
Robyn Slinger and Jeff Smax of Top Ten and Smax
S may be the only person that finds this interesting.
