Tales of Justice
Wyldfire is about the closest our campaign gets to the X-Men or Sky High, but it’s really closer to the Astro City Irregulars crossed with your typical hour-long adventure drama on television, such as Counterstrike from USA or Leverage from TNT.
But, hopefully, without the massive crime on the part of the heroes!
A hefty chunk of background info is available in this thread, conveniently located in the “Tales of Justice” forum and named “Background: Wyldfire Adventures”.
Adventurers in this team are at least old enough to drive, and preferably have reached the age of majority. They work at Dr. Gironde’s pet project, a “School for Special Needs Students”, where many of the students are mutants or the survivors of mad science — and, almost invariably, so are the adults. Some of Wyldfire are teachers, some are school staff, some work for other parts of Professor Gironde’s family holdings, a few work specifically in the dormitory where the students reside, and one former member was head of site security for the school and Dr. Gironde’s nearby home.
These heroes work the hardest to conceal not only their secret identity, but even the zip code of their home base. They have families and friends (who wouldn’t be helpless in a surprise fight, but what rational adult wants the risk of children winding up in real combat?)
Their adventures tend to be assigned missions by their employer/benefactor, to go solve a specific problem or prevent a potential trouble. They have some idea of preserving admissible evidence where the cops will legally acquire it, though that’s a skillset they still need to develop. The mission may require them to stop industrial espionage, catch a mad inventor’s destructive toys, rescue a hostage from Cobra^ Commander^^, or deal with terrorist interference at a S.T.A.R. Labs experiment. Enemies are generally either superpowered, or wielding unpleasantly experimental gadgets.
^ Oh, God, no, they’re nothing like this in the campaign.
