It wouldn’t be Star Trek without aliens! In canon, most species are humanoid. This is to save money on costumes, makeup and CGI, and to create empathy. Plus it makes guest stars at least a bit recognizable — rather useful during Sweeps Week.

Canon Alien Species

The canon cast page shows all canon actors who have played aliens. I try not to create canon anachronisms. In Together, technically, the infants are a bit of first contact. However, comforting a crying baby is hardly comparable to greeting Vulcans after your species has tested Warp Drive for the first time. Here are the species I’ve gone to the most:

Original Alien Species

See the alien cast page for alien names, actors and actresses. When one-off species

have been created, there are few visual cues. The reader should fill in the blanks with imagination. Other species boast considerably more detail. You can safely assume all species are humanoid. Also assume they are pretty close to our overall average structure, height and weight. That is, unless I state otherwise. Here are my original species , with example members of those species, plus the introductory story is listed.

  • Arisians – Milit is an Arisian. We first see them in There’s Something About Hoshi.
  • Azezans – they live on Azezi Prime. Furthermore, their government is the Azezan Council. They are an overly peaceful and passive species, and are vegan. Also, they wouldn’t harm a fly but also cannot and will not fight for themselves. Plus, as a result of their nonviolent nature, their planet is perilously overpopulated. They are purple in color. Siont is an Azezan. They first show up in The Adventures of Porthos.
  • Branch Borodin’s species – unnamed and unknown, the entire species travels together in the body of what looks like one individual. This concept first shows up in Shake Your Body.
  • Calafans – Treve is a Calafan. They first show up in Reversal.
  • Daranaeans – Libba is a Daranaean. They are originally seen in The Cure is Worse Than the Disease.

More original alien species

  • Darvellians – they are furry grey aliens who love extreme cold. They make a high-pitched whine. No individuals are introduced. As a species, they first show up in If You Can’t Stand the Heat.
  • Derellians – they are never seen, but the Derellian bat is, but is never actually described. Phlox and Morgan both keep one around. Hence it exists in both our universe and the mirror. This is because it makes an enzyme helpful in treating infections. Too much potassium is not good for it. We first see one in Reversal
  • Imvari – Griud is an Imvari. They first show up in Together
  • Nokarid – they are a colony species. Furthermore, they are small enough so the entire species can reside in a container about the size of a softball. There are only about 25 of them, total. No individuals are introduced. The plural of Nokarid is Nokarid. They first show up in More, More, More!
  • Olathans – they resemble the Azezans superficially. They are green in color, with blue blood. Revealing an exemplar member of this species is a spoiler. They first show up in The Adventures of Porthos.
  • Varg-i-yeh – this species hails from the Triangulum Galaxy, and is hell-bent on conquest. They first show up in Shake Your Body.

Yet More Aliens

  • Vilusun – this is a species without gender; they reproduce via parthenogenesis. Marikii is a Vilusun. They first show up in More, More, More!
  • Witannen – this species has small, vestigial wings. Also, in lieu of hair, they have flower-like appendages on their heads called chavecoi. Chavecoi are not really sentient. Instead, they are a kind of symbiotic hitchhiker on the body. Furthermore, they can photosynthesize and keep a Witannen alive in the event of a famine. Their home world, Dawitan, is in the Delta Quadrant.  In addition, they have had Warp Drive longer than most species and most of them have a significant superiority complex. Quellata is a Witannen. The plural of Witannen is Witannen. They first show up in Together.
  • Zetal – this non-humanoid species is from the Andromeda galaxy. No individuals are introduced. They are, as a species, introduced in Together

Hybrid Aliens

Hybrid aliens are canon.

Spock is only partly alien; the other half is human.  I used this framework, and interracial marriage as an analogy. Hence I considered what would happen when people of different species began to fall in love and wish to have children together. How is it possible? So what do the kids look like? And how do they behave?

Reversal begins this idea, and then the idea is expanded on (in story chronological order) in Freak School. Then it really hits its stride in the Times of the HG Wells series. After all, if you have peace with various species for centuries, someone may want to see how the other half lives. And sometimes that will lead to serious relationships. Some of the hybridizing happens with canon species, some with my own. Not every hybrid is part-human, either. Here are some of my featured hybrids:

  • Brandi – she is Xindi sloth and something else (Freak School);
  • Otra D’Angelo – she is Witannen and human (A Long, Long Time Ago);
  • Eleanor Daniels – she is Calafan (both copper and silver) and human (Temper);
  • Rayna Montgomery – she’s Klingon-human (Freak School);
  • Kevin O’Connor – he is Gorn and human (Temper);
  • Stellak – he is Vulcan-Romulan(Freak School);
  • Lenny Takei – he is human and Trill (Freak School);
  • Tellifa – she is Andorian and Xyrillian (Freak School);
  • T’Mia – she is Vulcan and Xindi insectoid (Freak School); and
  • Boris Yarin – he is Klingon, Xindi sloth and human (A Long, Long Time Ago).

Nonsentient Alien Species

In particular, the Calafans needed nonsentient species, and other needs cropped up. Hence here’s how they were fulfilled:
