10 Best Star Trek Villains In Only One Episode

These aliens had such promise. They were supposed to appear in a trilogy of episodes but ended up only appearing in one, serving in Conspiracy as a stand-in for what would later become the genesis for the Borg.

They are initially referenced in Coming of Age, where Admiral Quinn and Commander Remmick interrogate the crew of the Enterprise. Yet it is not until Conspiracy that they appear in the flesh, so to speak.

They are both frightening and insidious. While their appearance may not be all that disturbing today, their impact certainly was. They bring Starfleet to its knees effectively, getting right into the heart of Starfleet command. They manage to destroy star ships and because of them, many high ranking Starfleet officials are killed. Were they not identified, there is no telling how much damage they could do.

Like many species in science fiction, they are affected by that one major weakness - once the Queen dies, the rest fall like flies. Not even the Borg were immune to this in Star Trek: First Contact, and so it is forgiveable. However, they are still out there. That message that they transmitted from Earth was certainly beamed out into the Galaxy.

These are a race who could easily return in Star Trek: Picard. There are so many unanswered questions - where are they from? How did they arrive originally? What do they really want? Is anyone immune to their influence? With a slightly bigger budget, these bugs could do some serious damage to the 24th century.
