5 is Andrew Robinson who played Damar.
13 is Jennifer Gatti who played Ba'el.
Damn Salome Jens was a hottie in her day!
Correct, it's Damar, but the actor's name is Casey Biggs. Andrew Robinson played Garak.
BTW do you know that
Damar and
B'Elanna used to be married? It's a small world! That's why she was credited as Roxann Biggs-Dawson early on in Voyager (I'm watching season 1 currently). I guess she must've had the name Roxann Biggs before that, Dawson is her second husband's name.
12. Tracy Scoggins (More popularly known as Captain Lochley on B5)
...
17. John Vickory (more popularly Neroon on B5)
Yes, but what did they play on Trek? (without googling/IMDB-ing/Wikipeding/MemoryAlphing)
Tracy Scoggins was the Cardassian Engineer in "Destiny" that had a thing for O'Brien
John Vickory was the Catatonic survivor from the USS Brittain in "Night Terrors" then he was the Klingon Prosecutor that was out to convict Archer in Judgement.
BTW, you didn't rule out TrekCoreing!
He was also Rusot, Damar's friend from Cardassian resistance who couldn't let go of his hatred for Bajorans and had to be shot by Damar in the end.
On that note, I have to retract my statement that Cardassian look makes everyone look more attractive. This guy didn't look that great as a Cardie, and he's far more attractive out of makeup.
I cannot believe Martok looks like that. The first time I saw him interviewed out of make-up, I was shocked. I think he may look less like his character out of make-up than any other heavily made-up actor on DS9. And I was sure he was black too!
BTW let's not forget he also played Laas.

Contrary to popular belief, it seems that the majority of Klingons were played by white actors.
I actually put him as "0" as I figured he'd be too easy to guess as the only main cast member here. Kudos for guessing the Female Founder.

Some of the remaining ones were just in an episode or two, so they aren't that easy to remember let alone recognize. Although I thought #14 would be easy since she didn't look all that different in makeup.
Well, I did have a bit of an edge on Jens. I just happened to see her a few weeks ago on a Gunsmoke from 1971.

It was one that had her and Richard Basehart. I kept thinking she looked vaguely (very vaguely) familiar. I was shocked to see it was Jens in the credits as I had no idea what she looked like without Founder makeup nor any idea as to her age.
I was surprised and even shocked to learn a few of the heavily made-up actors' ages, and even more so in comparison to each other. Some of them turned out to be older than I thought, and some of them younger, like Max Grodenchik (Rom) who is actually just 3 years older than Aron Eisenberg who played his son Nog!
I also have to say that heavy makeup, like Klingon or Cardassian, usually makes it impossible for me to guess if the actor is white or black, I've been surprised a few times!
I love watching Gunsmoke for seeing all the different guest stars who also did Star Trek. Just saw DeForest Kelley in the first season of Gunsmoke (1955) where he had longer hair and a thick beard! Man, he looked different and somewhat weird.
I saw Nimoy playing a Native American on YT. Who else is there out of Trek actors?
