Science
In thought experiments scientists occasionally imagine entities with special abilities in order to pose tough intellectual challenges or to highlight apparent paradoxes. Examples include:

Descartes’ malicious demon - Cartesian skepticism (also called methodological skepticism) advocates the doubting of all things which cannot be justified through logic. Descartes uses three arguments to cast doubt on our ability to objectively know: The dream argument, the deceiving God argument, and the malicious demon argument. [23] Since our senses cannot put us in contact with external objects themselves, but only with our mental images of such objects, we can have no absolute certainty that anything exists in the external world. In the evil demon argument Descartes proposes an entity who is capable of deceiving us to such a degree that we have reason to doubt the totality of what our senses tell us.
