Regarding Star Trek: The Next Generation: I only know of one Vash.

The Zhat Vash are from Picard and are an organization, not a person.

The Zhat Vash are from Picard and are an organization, not a person.

Maybe they're like "James Bond" in Peter Seller's Casino Royale, where everyone who works for the Secret Service are all "James Bond"?
