I had the idea for a type of female predator, but much more sexual.
All female species like Asari, instead of hunting prey they hunt males of other species to breed with.
Hunt for alpha males of species like champions and heroes in order to get the best genes other species have to offer.
Doesn't spawn hybrids, but offspring is endowed with dad's epigenomes, allowing stuff like better immunity to viruses and survivability in harsh environments.
Warrior/Survivalist race and culture, so courtship rituals are stuff like fight sex or innawoods safari dates.
Does take "trophies", but its stuff like locks of hair, mementos of encounters, t-shirts warn after mating, or even her mates underwear all mounted in their own trophy rooms.
