The term "natural person" refers to an individual who is alive and breathing, as opposed to an artificial or legal entity such as a corporation or trust. Its antonyms can be generally classified into two categories: non-human entities or non-individual entities. Examples of non-human entities can include animals, plants, or even robots, while non-individual entities can include organizations, virtual or imaginary characters, or supernatural beings. Some possible antonyms for "natural person" include "artificial person," "corporate entity," "non-human entity," "fictional character," "supernatural being," "artificial intelligence," and "organization." However, these antonyms may not directly oppose the concept of a "natural person" since they have distinct legal and metaphysical implications.
