Do you wanna know a secret? If its small and personal, that's pretty much on you. But if its nasty and important, or well-hidden and expensive for the people hiding it, Well then, Argus is the person you hire to get it. Maybe someone's already hired him to find out your secrets. Like real identities behind those masks. Or weaknesses. Interested yet? Too bad. Your enemies certainly are.
Argus is a PL 10 threat to add to your Mutants & Masterminds campaign.
