Orions are known for their distinctive green skin. Orion males are typically bald and, on average, taller and more muscular than an average Human male. Orion females are very animalistic in nature, known for their extreme carnal appetites and their innate skill of seduction: they are kept in slavery by the males. The Human male can rarely resist the alluring dance of an Orion slave-girl.
But their slavery is only a pretence that allows them to conquer other species by deception. The females are sold on the Orion slave market allowing them easy access to new targets for their unique physiology: very soon the ‘owner’ begins taking orders from his new ‘slave’.
