When Mutant City Blues came out, examples of super powered police procedural TV shows were hard to come by. Back then we had to imagine a hybrid of those two genres. With examples now popping up on network and streaming TV, you kids today have it easy!
“The Flash” comes closest to the structure envisioned in MCB. (Full disclosure: I recently caught up with the first season on streaming and haven’t seen any of the second.) Barry Allen is a civilian forensic specialist who works hand-in-hand with a police detective-slash-father figure. Cases of the week involve super-powered bad guys, referred to here as metahumans. Like MCB, the powers all stem from a single event and yield to scientific analysis. The rest of the DC universe, as seen in connected shows, may have magic and other mystery-busting elements, but at least in the first season, Flash mysteries can be cracked with good old reliable technobabble.
The show diverges from MCB by having most of the clue-gathering take place in a civilian lab facility rather than down at the squad room. But there’s still a gruff lieutenant whose chief function is to bark at Barry when the case isn’t closing fast enough.
A darker, unconnected adaptation of the DC universe, “Gotham” started with an interweaving of “Boardwalk Empire”-style gangland soap opera with case-of-the-week cop investigations. It has shed some of its unevenness in its second season by largely ditching COTW. Although literal super powers don’t figure in its mythology, MCB GMs could use it as inspiration for an alternate campaign frame in which mutations have only begun to manifest, and a city reacts to the first tremors of what will become a dangerously changed world.
“Jessica Jones” points the way to an alternate campaign frame in which our relatively low-powered super-PCs are private detectives and those around them. Its first season still shows a few vestigial traces of the cast of the week structure that must have been part of the pitch when it was first envisioned as a network show. As reconfigured for serialized Netflix binge-watching, we mostly see Jessica use her investigative abilities to turn the tables on a threat that’s coming at her. In that regard, it’s more like Night’s Black Agents than MCB. It’s easy enough, though, to use it as a tonal reference and imagine an MCB game in which the characters free themselves from barking lieutenants and concern for what Internal Affairs will say by making themselves investigators for hire.
