Brainstorming pt1

I want a universe of super humans in my comics. Much like the men in black with the aliens hiding in plan view and the alien police. But I want to have super humans/conduits that live normal lives in the comic I'm creating. This will not be easy. I want to create African looking  characters because I myself am of African decent. What I need to do is stat writing stories and story board my ideas. In the past just thinking and creating hasn't worked. I need to make enuff stories then create the comics. That's the only way this will work. I need a name from this meeting room. I need to make a list of heros/villains and in between's. I need a good back story so readers will be drawn into the story. I need a name for the city/citys. I've decided to create in this comic different teams or clicks called brotherhoods/sisterhoods where each character may join outside of the super humans/conduits that police the areas in which they live.
