10 Most Irredeemable Star Trek Villains

They only ever appeared in one episode of Star Trek (aside from a mention by those 'butt bug' conspiracy theorists in Lower Decks), but they've had us checking the backs of necks ever since! Not officially named 'the Bluegills' in canon — the species was first called that in Star Trek Customizable Card Game — these terrifying, nightmare-inducing parasitic creatures wormed their way into the highest echelons of Starfleet Command and turned dinner time into a horror show. An infected Admiral Quinn did get in some impressive high kicks, though, for his years, so perhaps it's worth giving them a try. And Admiral, bit embarrassing, but your stunt double is showing!

Thoroughly alien, it is the manner in which the bluegills go about their villainy that makes them so irredeemable. They enter through the mouth (not the butt, sorry) and take complete control of a victim's mind and body, yet still claim "we mean you no harm. We seek peaceful co-existence". Yeah, yeah, and Worf’s a 'pacifist' now!

They also didn't hesitate to blow up an entire starship and crew (the Horatio) once its captain was onto them. And let's spare a thought for poor old Commander Remmick; he had to have their mother inside him, only for his head and chest to be phasered off. Picard and Riker must have been in therapy for months!

It's tough to see these little (and one large) blue buggers ever changing their ways!
