Star Trek: 10 Strangest Alien Species
Out in the depths of space, it all gets a little strange...
When your job is to boldly go where no one has gone before, you inevitably find things fly off the rails quickly and frequently. Getting in those kinds of situations seemingly happens every episode on different Star Trek series. Well, at least to the crews and ships who are the focus of said series. Other people didn't seem to get up to the shenanigans the respective crews of Deep Space Nine, Voyager and various Enterprises did.
The vast majority of the time, they ended up dealing with aliens fans were used to seeing. Klingons. Romulans. Vulcans. Then there were the other times when the different Star Trek crews encountered new life and new civilizations that often seemed to defy explanations. Even when an explanation was attempted, it still didn't cover off every detail in many cases.
Often times the key to a great Star Trek episode, regardless of which series you're watching, is a unique alien species that brings something new to the table. Or one that's just so strange that it becomes iconic, even if that species only pops up only in an episode or two.
10. Borg
Star Trek fans are so used to the Borg at this point that they almost seem commonplace. But when you take a step back and really look at them, you start to realize how strange a group they actually are.
The Borg were first introduced on The Next Generation when Q arranged a meeting between them and the crew of the Enterprise-D. Guinan had some previous knowledge of the Borg as they had attacked her homeworld, scattering her people around the galaxy. The only reason the Enterprise survived that encounter was Q decided to break the fight up. Subsequent meetings with the Borg were equally difficult.
While they are not a species in the traditional sense, the Borg bolster their ranks by assimilating members of other species. They build their forces by taking members of other species and their technology, and combining it with their own. Once an individual is assimilated into the collective, they are essentially reborn.
The implants given to new "recruits" turn them into drones and gives them devastating abilities. The Borg's non-traditional command and organizational structure gives them several advantages in combat situations.
