I was just thinking of how many people want a certain character to get a shot as solo hero. When we're talking team heroes that haven't had that opportunity, though, I see a lot of grabbing from other titles/characters.
I think a hero needs their own supporting cast and their own villains. So that is the exercise for today.
Pick your hero (someone who had never had an ongoing solo title), and give me the set up. You cannot have other previously existing characters as supporting characters or villains (including organizations) unless they were created for a story for your character originally. That's the limitation. That's the creative aspect I want. How you are going to have your character work in a relatively stand-alone sense. What villains or mythology they will contribute to the DC universe, rather that just how they can use what's already there.
Occupation, location, general goals - what are they? If your character was depicted differently in various titles (and most have been), then which characterization works for you. In personality and powers.
There are a few characters I'd love to read ideas for. But I lack the creative skill to answer my own challenge. So I'm crowdsourcing the imagination part.
