The Daxy are a matriarchal race of aliens resembling reptiles from the book series 'Assignment Risk' by alephkeller.

With varying scale-colors, Daxy females stand anywhere from seven to ten feet tall. Their males are estimated to be much shorter. Strangely, the females have breasts and bear live young too. As far as natural defenses, they have talons on their claws and feet, and rows of sharp teeth in their muzzles. They are digitigrade carnivores, and are counterbalanced by a heavy tail that can range from three to six feet long. The females also emit pheromones that promote submission and desire in males of most species. In humans, the pharmacology of Daxy pheromones has been compared to MDMA and other empathogens.

The existence of many more females than males, proportionally, has defined Daxy culture and conflict since their beginning. An old and vastly advanced empire, they cross universes looking for males to conquer. It didn't take long for the Daxy to subjugate humanity after finding Earth. Their exotic biology allows them to procreate with most of the races they've come across.
