Top 10 Star Trek Alien Races

The Borg are the best. I mean, the Borg cubes, if you look on Memory Alpha, have weapon arsenals that replicate weapons they think are best for assimilating the enemy. They are one of the very few species that can go into transwarp (warp 10+) and have the most complex history/story line. (Connections with the Caeliar) If a Borg cube and a Cyberman got into a fight, the Borg would get shot, die, and another Borg would beam in, get shot, stare at the Cyberman blankly, and assimilate it.

Borg are the most dangerous and the coolest-looking aliens in the whole of Star Trek. They have a very cool design and are far more menacing than Klingons and Romulans.

Many Star Trek series feature an important Vulcan character (Spock, T'Pol, Tuvok, etc.), and there's a reason why. With Spock in The Original Series, it was the first time in the history of television that an alien character was portrayed as an actual character, not some kind of monster to defeat. It was groundbreaking.

In large part because of this character's popularity, Star Trek was renewed and eventually gave us all the other movies and series. And because of the popularity of the race and the character (Spock), they created their cousins, the Romulans, some of the coolest antagonists. Thus, the Vulcan race is very important.

They have blue skin, white hair, and antennas. Shran is an Andorian.

The strongest species, as well as the most hardened through the years. Ale is often helpful to them. Klingons would be the first selection for Starfleet, with Humans as a close second. Klingons have a lot to offer, and the table is set instantly when they are around. Like Chewbacca, they do not enjoy defeat, even by smarter opponents.

Q is amazing and should be in the top three. He's so funny but always ends up being beaten by Picard.

The Q are a continuum of seemingly eternal and omnipotent beings. Q is one of the Q.

Also known as the Changelings. I like that name.

Not only are the brilliantly acted characters of Garak and Gol Dukat noteworthy, but the species as a whole is a brilliant addition to the Star Trek universe and a great vehicle to tell stories.

What really makes them unique is their militaristic and unforgiving societies, which contradicts the Cardassians' unconditional love and compassion for their own families.

Essentially replaced the Romulans in TNG and became on-off adversaries in DS9. Slimy and treacherous but somehow extremely noble. Garak is my favorite Trek character.

They are distant cousins of the Vulcans but are much meaner.
