I guess that a spin-off thread to this could be: "What aliens do you want to see show up in Abrams Star Trek in the future?"
I mean, sure, new species are cool too - especially non-humanoid species...but it would be nice to see familiar species too, as it adds a sense of...continuity.
SO we have seen Vulcans, Romulans (t6hankfully without the stupid forehead ridges)...Klingons now...and Orion woman...and two Caitian females...so, what next?
I certainly DON'T want to see and Borg or Ferengi or too many TNG species unless they were already known by the time of TOS.
I certainly would like to see more TOS and TAS species - Telarites and Andorians (which modern Trek too *way* to long to bring back, imho!)
And ever since we saw that CGI alien helms...creature...in Star Trek '09, I know that a lot of us would really, REALLY like to see Arex's species from TAS. (*Easily* done with modern CGI!)
And since the Gorn have been mentioned, why not? (I guess the Federation's expanded...expansion...means that they were contacted earlier in this timeline...)
Ooooh...and how about a Medusian (but in a container, of course!?)
Most of all, those are the species I'd like to see most. But in addition to that...
I think a Xindi species or two and maybe a Suliban - if only in the background.
I'd like to see a Denobulan.
Of the TNG species that were around in TOS, the Naussicans have been around since Enterprise (thanks to some retconing) and the Cardassians have been mentioned (a larger, beefier Cardassion would ROCK) so Bajorans could turn up, and I think that at least some Trill had visited Earth in TOS time, according to Dax (even met McCoy, so that would be cool to see a Trill female talking with McCoy!)
Where any other TNG species around the Alpha Quadrant then...? Benzites?
What abo0ut the Breen? (Since JJ like Star Wars, and is gonna be in charge of it...a background Breen would be a nice Easter Egg...)
And since Deltan's were mentioned, a Deltan would be nice.
And speaking to TMP, I think that some of the background species from The Motion Picture that we only saw once would be cool...even if just in the background again. I like some of those designs - and now, they could be realized more realistically.
Any others? What about those short guys from "Journey to Babel"? Easy species to make, just cover some...small people...with gold makeup!
Any species I left out that you would want to see in nuTrek? (Certainly none of the many, forgettable bumpy-forehead alien that we saw in TNG and everything after...)
