Imagine an alternate version of 2021 where there are humans with special abilities. There exist those with super-strength, flight, pyrokinesis, your standard comic book powers, but semi-grounded in reality. I would imagine most people, even with incredible abilities, would choose to lead normal lives. But what about those that wish to use their abilities for the good of others? To fight crime?
A vigilante hero is just as likely to get arrested themselves and face jail time. Unless they have an ability granting them invulnerability, they would be likely to get shot in the back if attempting to evade police capture.
If a legally sanctioned super-powered team were formed, how would they operate? Would they be small strike forces put together to assassinate super-powered dictators? Considering the fact that being super-strong means that you could toss henchmen around like ragdolls but it wouldn't prevent one of them from popping you in the back of the skull, would they carry firearms to support their ability? Would they be decked out in full protective gear like a soldier?
Or maybe they wouldn't fight crime at all. In a semi-realistic setting, would it be better to use powered individuals to act during natural disasters? Maybe someone who could fly would be used to carry people to safety during hurricane? Would a pyromancer be used to make controlled fires to fight against forest fires?
