For a Modern Supers Game Only
In one of my campaigns, the first costumed hero appeared only a few months before any other costumed heroes. There has always been paranormals since the beginning (all with magical, psionic, or supernatural powers), over the last few decades a few metas (paranormals of extreme power - super hero level) began to appear. They were sucked into the secretive supernatural organizations
After his first appearance rescuing people after an earthquake and interview on CNN, Guardian, the first Super Hero, set up a non profit corporation. This corporation handled his affairs. It managed the money he received from donations, rewards, and toy licensing deals. It provided him a legal defense fund and most importantly health and liability insurance. He was actually payed by the corporation, listed as a paranormal consultant.
After his death (on television), other costumed heroes finally moved out of the shadows into the light. The Guardian Inc provided most of these heroes, those who upheld the law and social support, with the same legal and financial (revenue from posters, toys, et al) support and insurance, that they gave Guardian.
The main function of Guardian Inc is to support heroes with legal and financial aide that would normally compromise any pretense of secret identity. The legal identity of the organization is used for all the Hero’s transactions. This plus health insurance (because in the real world, heroes can get badly hurt in a fight) is their main function.
The Guardian’s lawyers work with the ACLU to support Meta-Human and Para-Human rights, works with the Federal Government to institute meta-human equality laws (disallowing paranormals from being discriminated or treated as non humans), working on liberalizing various identity and vigilante laws around the country, and with various governmental agencies to deal with paranormal offenders. They also defend Guardians (Heroes) from various lawsuits and many fraudulent criminal charges (often this is contracted out to several higher profile law firms). Guardian Inc also hold the property rights for several “Super Hero Teams” buildings and vehicles.
It is a little known fact that merchandising of toys, t-shirts, and books, is their main source of revenue.
The Organization allows heroes to function in the world of laws.
