Reptoids, also known as reptilians, are a fictional race of extraterrestrial beings often described as resembling reptiles or lizards. They are commonly featured in conspiracy theories, where they are said to possess advanced technology and the ability to shapeshift into human forms. These theories suggest that Reptoids infiltrate human society, often taking on roles of power and influence. The concept of Reptoids gained popularity in the late 20th century, particularly through the works of authors like David Icke. While there is no scientific evidence supporting the existence of Reptoids, they have become a notable part of modern mythology and popular culture, often appearing in various forms of media.
