Next Star Trek race LORA for flux, Klingons. Trained to not include clothing, so you wont be able to generate klingons in iconic armor, probably i'll add it some day as standalone LORA.
UPDATE ADDED LTX2
-trigger is still "klingon with long hair" (and beard for males)
The general trigger is "klingon". but to make sure that you are getting what you want use "klingon with ridged forehead and long hair". The changes are more visible to men than to women, and in close shots more then in far shots (both cases can be fixed in a next version), but as seen on the example pictures there should not be any problems with common use cases. The weight should be in 1-1.3 range.
Because it was trained to not include deafult clothing, its a good idea to include some clothes in the prompt.
