Looking at Praetor White's contact info, the first thing you see is "Commander of the PPD Powers Division."
Organizationally, the Powers Division is a branch of the Praetoria Police Department. Functionally, they're quite disconnected, and the whole schism between the super and normal divisions of the PPD is a central part of the Praetoria lore.
Since the story arcs in and of themselves make the distinction between "the Powers Division" and "everyone else in the PPD," I suggest Powers Division have their own category.
