Just do however you feel or know you can do best on doing first.

Or to put it simply, if you want to do your characters first as well as the "power system" (i assume you mean the OC's powers, right?), you can do that first.

Other times, there can be people that may do their verse first and character afterwards but in any case, you can start it out however you want to start out.

Just make sure you follow our Rules for Original Character Profiles format here and you'll be fine.
