Yeah, I don't want to pursue this digression too much, but I think the GT writeup says that fighter pilot K'Kree, or K'Kree who are deemed insane or otherwise able to kick the innate fear and sit in a cockpit or pilot small starships, are looked upon with fear and a little envy.
So, those K'Kree do exist, but they're essentially mental patients of sorts, or rare breeds.
I do wonder about the possibility of K'Kree settling hostile worlds, or worlds needs enclosed environments. It seems doable, but it seems that such a colony would require the same kind of expanded parameters as their starship design criteria.
Instead of enclosed domed shelters that other species can live in by themselves with maybe two or three other people, I can see K'Kree setting up stadium sized pre-fabs. Maybe it's because I still have "Logan's Run" on my mind (see my blog), but I wonder if maybe some "radical" K'Kree architect or designer maybe came with a concept like that, and how that might alter K'Kree space.
The problem being that (1) there aren't many of those loners, (2) you would have to concentrate them in one area to be able to build the domes in the first place.
How do you build a dome colony as a normal (omnivore or carnivore descended) species? In suits and vehicles. Not a practical option for the K'Kree.
They don't TRUST the loners. They use them in the single most dangerous job... fighter pilot or Tank crewman. (Even then, they still suffer for their size, and become even and ever more erratic.)
Note that a K'Kree tank is likely to be robotic. They make extensive use of robotics.
So a dome colony would must needs be dropped almost completed. And what would it do? Most of the reasons for dome colonies post-FTL have to do with refuelling and mining. The K'Kree are just as likely to part tank farms in orbit and leave the domes in space, in a big flat array with interconnects.
Mining? They're likely to stay in orbit, and control robot miners remotely. The extra tenth-second to orbit isn't enough to matter. That way, they can have near perpetual sun, and keep expanding more easily.
One must keep in mind: The K'Kree are not "Funny shaped men" - they're not even mammals. They aren't even gender equal; K'kree females are VERY different. They have stronger and clearer sexual roles than even the Aslan; and have 4 phenotypes in CGen. They don't inbreed between the 3 male phenotypes (it can be assumed the females also have 3 genotypes but all express as the 4th phenotype).
The are inhuman. They wouldn't ask if that tofurky was really meat - they'd assume it was, and treat you as out to eat them, too. And they're nutso-protective. They don't learn to tolerate outsiders (unlike the Aslan); they don't want to emulate them, and they consider even other herbivores a bit of a problem - competition for food. They really don't want to control outsiders, either - they (especially the Lords of Thunder) have a belief in their manifest destiny to eradicate all predators everywhere in the universe and to rule the universe.
