The term "Reptilian" often refers to a fictional race of extraterrestrial beings that are said to resemble reptiles. These creatures are commonly associated with conspiracy theories, which claim that they can shapeshift and infiltrate human society. The idea gained popularity in the late 20th century, particularly through the works of authors like David Icke. In popular culture, Reptilians are frequently depicted in movies, television shows, and literature as malevolent entities seeking to control or manipulate humanity. They are often linked to themes of government secrecy and hidden agendas, contributing to a broader narrative of distrust in authority and the unknown.
