So - I swear I tried to google this yesterday and came up empty. I have a weird question.

Was there a third Sci-fi series that aired around the same time as Babylon 5 and DS9? It may have had a plot thread that involved genetically engineered space spies? Like telepathic central intelligence officers? Or am I thinking of B5?

I was in college at the time (mid 90s) and didn't have the free time to watch much TV. I caught an episode here or there and would occasionally talk about shows with my friend Spencer. I'm definitely not thinking about DS9 because I've seen that in its entirety fairly recently.
