And how are you being paid for this government contract work without using your real identity?
If you
really start thinking deeply about how most superheroes with secrets interact with the mundane aspects of their world as depicted in comics, you realize that they’re doing at least one or more of:
1) they’re forging documents
2) they have friends in government pulling strings
3) they’ve got a network of associates working with them who either know their IDs or don’t care
4) they’ve engaged in a modest amount of shady stuff at the bare minimum
And the bigger the base or higher the tech, the more of those have to be true.
What’s the Batmobile’s license plate? Who built the Batplane? What OS does his computer run on? How is the Batcave powered? What does it say on Bats’ pilots license?
How did Peter Parker manufacture his web shooters?
Are Tony Stark’s Iron Man lab & manufacturing facilities OSHA compliant?
Who did the inspections on Avengers Mansion or Xavier’s school? Who does the maintenance?
If you’re openly toting firearms & bandoliers of reloads & ordinance, where’s the police response? SOMEBODY’S going to call.
Etc.
