Nova

In Guardians of the Galaxy, the Nova Corps is introduced as a sort of outer space police force. This is relatively consistent with their comic book counterparts. The main difference, however, is that the comics have always focused on the Nova from Earth. There's been two major human Novas, Richard Rider and Sam Alexander, and either one would work well for TV. People love cop shows and teen dramas. The main difference between the two characters is that Richard Rider was chosen to be a Nova, while Sam Alexander found his missing father's old helmet and gained his powers from that.

The show could decide to focus on either telling the story of a rookie space cop or a kid searching the cosmos for his missing, ex-Nova father. Either way, it's just a good excuse to send a teenager zipping across the stars. Think Saved by the Bell meets NYPD Blue meets Star Trek, only with less early '90s fashion and better special effects.
