This actually sounds like a good idea for a series: A group of superheroes tracks down a criminal organization that hides out where the law can't touch them...within the collective unconscious. Each week, a criminal manifests himself as a powerful archetype, and the heroes must battle by using their own archetypes to heal the mental traumas of the person whose body the criminal is using to commit crimes. Thus, by healing the victim's psyche, the heroes block off one more access into the world for injustice, setting up a final battle where the villains will be forced to incarnate themselves physically or risk being trapped within the shadows of humanity's unexpressed dark side forever.
Why does this depress me? Because I came up with the title first.
