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, but 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 is encouraged to fill in the blanks with imagination. Other species boast considerably more detail. All species can be assumed to be humanoid, and pretty close to our overall average structure, height and weight, unless stated otherwise. Here are original species I have created, with example members of those species, plus the introductory story is listed.

  • Arisians – Milit is an Arisian. They are first seen in There’s Something About Hoshi.
  • Azezans – they live on Azezi Prime, and are governed by the Azezan Council. They are an overly peaceful and passive species, are vegan, and 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 are introduced 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 is introduced in Shake Your Body.
  • Calafans – Treve is a Calafan. They are introduced in Reversal.
  • Daranaeans – Libba is a Daranaean. They are originally seen in The Cure is Worse Than the Disease.
  • Darvellians – they are furry grey aliens who love extreme cold. They make a high-pitched whine. No individuals are introduced. As a species, they are introduced 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 (so it exists in both our universe and the mirror) because it makes an enzyme helpful in treating infections. Too much potassium is not good for it. It’s first introduced in Reversal
  • Imvari – Griud is an Imvari. They are first seen in Together
  • Nokarid – they are a colony species, and are small enough so that everyone in the 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 are introduced 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 are introduced in The Adventures of Porthos.
  • Varg-i-yeh – this species hails from the Triangulum Galaxy, and is hell-bent on conquest. They are introduced in Shake Your Body.
  • Vilusun – this is a species without gender; they reproduce via parthenogenesis. Marikii is a Vilusun. They are introduced in More, More, More!
  • Witannen – this species has small, vestigial wings and, in lieu of hair, they have flower-like appendages on their heads called chavecoi. Chavecoi are not really sentient; they are a kind of symbiotic hitchhiker on the body, and can be used to photosynthesize and keep a Witannen alive in the event of a famine. Their home world, Dawitan, is located in the Delta Quadrant. 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 are introduced in Together.
  • Zetal – this non-humanoid species is from the Andromeda galaxy. No individuals are introduced. They are, as a species, introduced in Together


Hybrids are canon.

Vulcan (Star Trek)

Spock is only partly alien; the other half is human. From this framework, and using interracial marriage as an analogy, I got to thinking about what would happen when people of different species began to fall in love and wish to have children together. How is it done? 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 and really hits its stride in the Times of the HG Wells series. After all, if you’ve been at peace with various species for centuries, someone’s bound to want to see how the other half lives — and sometimes that will lead to serious relationships. Some of the hybridizing is done with canon species, some with my own. Not every hybrid is part-human, either. Here are hybrids I have featured:

  • 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. Here’s how they were fulfilled:

Thanks to ArtItUp who created the wonderful photomanipulation of Mandy Patinkin as Saddik.
