Register them all

Most superpowered individuals register with their respective governments. Some governments are more open about their members than others are, but all of them hold back a few names. Whether you call them heroes or villains, it all depends on the circumstance, I guess. And some individuals prefer the vigilante track. There is no global registry, so sometimes there’s two or three records for the same person or different translations of their name. So, what you have there is Captain Cyclone from Sri Lanka, not Captain Hurricane from old New Orleans, we can bring you in peacefully or not. Your choice.
