I have been watching Star Trek: Voyager for the last few days and they have been categorizing humanoids by class. So far, I heard of class three and class five.
I checked on Memory Alpha and the available information on that topic is ludicrous:
Class 5 humanoid is a humanoid categorization class used by B'Elanna Torres to categorize the Vhnori decaying bodies found on an asteroid around a planet on stardate 48623.5 (2371).
Yes. That's really everything.
Does anyone have an idea what each of those humanoid classes mean?
