When Reptilian Overlords are not deceiving humans there is one thing which occupies their lives. Battle Mating. Reptilian Overlords are bloodthirsty horndogs which live mostly for battle and sex. Reptilians Overlords mostly fight over mates. Male and Female Reptilian Overlords fight eachother during mating.
Upon birth a Reptilian Overlord eats their own mother.
If a two headed Reptilian Overlord is born the two heads try and eat eachother.
Reptilian Overlord women are extremely beautiful and it is completely understandable why they are worth killing your own brood for.
