10 Coolest Blue Aliens in Sci-Fi

10 Coolest Blue Aliens in Sci-Fi
Written by Izak Van Heerden

Sci-fi might be famous for its little green men, but the truth is that some of the greatest alien characters come in a broad range of colors. If you’re looking for the ultimate in cool, though, you’ll definitely want to take a look at these ten blue aliens.

Nightcrawler (X-Men 2)

Though he’s actually the second furry blue character introduced in the X-Men comics, Kurt Wagner was the first one to show up on screen. Played by Alan Cumming, Nightcrawler had a unique visual style and amazing teleportation powers that were featured in one of the movie’s best scenes. A kind and devout character, Nightcrawler’s demonic looks proved that real beauty was on the inside.

Grand Admiral Thrawn (Star Wars)

Grand Admiral Thrawn got his start in the books by Timothy Zahn, but he’s quickly become one of the best-known characters from Star Wars’ extended universe. Featured in Rebels and name-dropped in The Mandalorian, Thrawn was an urbane and calculating threat that stood head and shoulders above the legions of Vader-wannabes that inhabited the Star Wars spin-offs. Though Thrawn has shown up in the live-action films or television shows yet, the fact that he’s shown up virtually everywhere else should clue any viewer into his popularity.

The Na’vi (Avatar)

A nod has to go to the Na’vi of Avatar, both for starring in one of the highest-grossing movies of all time and being the only character (so far) with their own theme park area. The tall, ponytailed Na’vi were visually interesting and had a unique society, helping viewers to quickly figure out that they were actually way more interesting than Jake Sully.

Yondu Udonta (Guardians of the Galaxy)

Both Yondu and Nebula are awesome blue characters in Guardians of the Galaxy, but Michael Rooker’s performance gives Yondu the edge. He’s charming enough that you can forget that he’s a bit of a monster, but his whistle-guided arrow is definitely cool enough on its own to earn him a spot on this list. The leader of the Ravagers and the only real father-figure that Starlord ever had, he definitely more than earned his spot on this list.

Abe Sapien (Hellboy)

Abe Sapien is a character that’s appeared not only in comics, but in live action and animation as well. The Hellboy films definitely simplified the blue character significantly, but he was a major player in the comics. This aquatic humanoid was nearly as strong as Hellboy in the comics and had his own adventures that involved time travel and ghosts, while the movie version had psychic powers and played a huge role in the second movie. Though Abe might not be the star of the show, he’s still the coolest blue guy in the long-running Hellboy universe.


The Mythrol (The Mandalorian)

The Mythrol was one of the very first characters that viewers saw in the Mandalorian, and his appearance set the tone for the show. While he was a little bit silly, he was a great audience surrogate that helped us all understand just how good Din Djarro is at his job. While he seemed like the kind of character that would be a one-and-done, his next appearance in the second season proved that he was more than just comic relief.

Chell (Star Trek: Voyager)

Chell, a Bolian, was a fairly unique character on Voyager. Not only was he a Maquis crewmember, but he was the first Bolian in Star Trek that wasn’t played a purely comic character. Though it’s hard to argue that he was very good at his job, he had a spectacular spotlight episode that helped show exactly why he was the kind of person who would join a rebel crew as well as why he was such an asset to the Voyager crew.

Zaahn (Farscape)

Zaahn is definitely one of the most memorable characters from Farscape. Bald, blue, and beautiful, she was one of the first members of the Moya’s crew that viewers met. Spiritual but still fun, Zaahn was not only a character that grew a lot during the show but one that helped other characters to flourish. Though she didn’t make it all the way through the show’s run, she’s a character who never quite disappeared from the show’s DNA.

Megamind (Megamind)

Finally, there’s Megamind. Played with absolutely manic energy by Will Ferrel in the animated film of the same name, Megamind was actually one of the most effective supervillains to show up on screen. Sure, he might not have been great at pronouncing a few words and he certainly had one of his biggest plans go awry, but he managed to both defeat the good guy and get the girl in the end. Not bad for a blue guy with a giant head.
