Reptilian vs Lizardian
They share a look but not a source. Lizardians are fictional creatures; Reptilians are the same image reworked into a conspiracy theory about hidden rulers.

Race 24LizardianThe SurvivorsFictionalFolkloreThe difference
The Lizardian is the fictional ancestor of the Reptilian. Serpent-men and lizard-people belong to pulp and comic fiction from the 1920s onward, drawn as monsters. The Reptilian took that image into conspiracy literature, where it became a hidden ruler rather than a creature.
The Atlas separates them so that readers can see where fiction ends and the modern belief begins.

In their own dossiers
Descriptions of the Reptilian are consistent across fiction and conspiracy literature because the second borrowed heavily from the first. The being stands between six and nine feet tall, heavily muscled, with green, brown, bronze or grey scales, a ridged skull or crest, and a face somewhere between human and lizard: a flattened nose, a wide mouth, and eyes with vertical slit pupils in gold or yellow. Hands are clawed, usually with four digits. Some versions have a tail, dorsal spines or a frill.
The Lizardian is the reptilian archetype in survivor form: leaner and more mottled than the Reptilian, with green-brown scales, a ridged skull, slit pupils and a wiry build suited to scarcity rather than dominance. Renderings give it worn, practical dress and a wary expression.
