Sorry for the long delay, but I already did a search of ShareCG before I posted that request, and I just searched again. I did a Google search as well, and couldn't find anything. I also want to add the following:

Stargate:

Tau'ri and Jaffa (Teal'c, Daniel Jackson, Samantha Carter, Jack, Bra'tac, Rya'c, Drey'auc)

Star Wars:

Ahsoka Tano (I found a model of her, but it's in a format that Blender doesn't have an import script for)

Star Trek:

Augments (Khan will do, but I want both the ST2: TWOK version and the Kelvin Timeline version)

Borg (Seven of Nine and the Queen. I've been looking all over for models of them. All I've found are their ships and a few weapons.)

Vulcans (I know Spock is available on some sites, but I'm mostly looking for T'Pol and Tuvok.)

Hybrid individuals (B'elanna Torres, Deanna Troi)
