Star Trek: 10 Strangest Alien Species

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.
