Creatures that didn't evolve naturally. There exist many types of artificial creatures, including robots, cyborgs, genetically-engineered beings and organic constructs - the latter exemplified by creatures such as Frankenstein's monster, the creations of Dr. Moreau, or the organic robots of Karel Čapek.

Characters classified as mutants and mutates do not belong here, as they aren't created intentionally (if they are they should qualify as genetically-engineered beings instead).
