Which versions of aliens do you imagine?
This question mainly goes out to the writers, but other readers should feel free to answer too. I've been wondering for quite a while now, which versions of the aliens the writers or readers have in mind when they write or read stuff involving aliens like the Tellerites or the Andorians, who have gone through numerous real universe make up changes? Personally I usually tend to go with which ever version I like best, which is usually the newest and most realistic one. For example the Enterprise versions of the Andorians and Tellerites, and of course if there is an in universe reason for the different look, like with the Klingons then I just go with whichever version matches up to that time period or place.
