Superheroes often have a Secret Identity which they conceal from the world, or perhaps just secretly engage in heroics. They do it for lots of reasons- maybe to keep themselves or their loved ones safe, and so they keep them willfully ignorant. But when you do that, you’re likely to run into some complications. Sooner or later, friends, family and dates are going to wonder why you keep running out on them. You’ll find yourself missing school and work, since crime doesn’t exactly let you keep regular hours. Eventually, you might found your civilian identity held captive, with no way for the 'hero' to show up. So it can be tough to keep that secret identity, well... secret.
