Here is a screencap from Star Trek: Discovery, Episode 4 of the first Season:

enter image description here

What species is the big-headed insectoid/arachnoid/reptilian/somethingoid alien to the left of the screen, standing on the station directly behind the black girl? Here is a close-up of our new friend in all of his beauty (well, sort of):

enter image description here

Is he a new alien created appositely for Discovery, or was this species already seen before in the franchise? What do we know about him or his species, other that probably trying to wear his jersey is not his favourite thing to do in the morning?

  • An answer to this question will need to wait. I do not believe any source has specified either the species name or the personal name of the character. Oct 11, 2017 at 23:31

    I asked because his appearance is somewhat familiar to me, but I can't say if he reminds me an alien from Star Trek or from somewhere else

    @NKCampbell Is green all right? :) More seriously, with all the red parts in the background, another color is standing out more.

It might be an "Osnullus", a name which is attached to some large head prosthetics in behind-the-scenes material, but I can't find a primary source connecting the alien we see with that name.

Here is a slightly clearer picture of the character.

enter image description here

Several sites have reported Alex Kurtzman describing the character during a set walkthrough. Scott Collura reported the following from a set visit.

During our tour with the make-up prosthetics department (seen here with Lt. Saru's headpiece and Sarek's ears), we learned that at least two new types of beings will be part of the USS Discovery crew. One is known as Osnullus (he/she/it has a big old alien head) and the other is a synthetic human-like female character called Airiam who works on the bridge of the ship. The goal is to have aliens naturally mixed in with the human characters in the background as well as in the main cast.

Osnullus has been described as a new race for Discovery, and I am not aware of any similar-looking creature in previous shows or movies.

Other Sources

TV Guide mentions James Mackinnon showing off "Osnullus". However, the image used in that piece is of Saru's headpiece.

    Funny, os nullus roughly translates from latin into no mouth .

    Can you provide some links to better reference this?

    trekcore.com/blog/2017/09/… - tvguide.com/special/fall-preview/gallery/… - best links I could find that at least indicate it's a real name. The make-up image sadly doesn't have enough detail to confirm. In fact, it looks more like the makeup in the two links displayed are actually Saru elements, not the alien in question

    The cowl in that image is definitely Saru (check the ears), which is why I didn't link it. There was clearly discussion about another prop, but no images of that other headpiece.

I think 'Osnullus' is the character name, could also be the species. But the actress, Avaah Blackwell, has it listed on her account under that name.
