"Mowgli syndrome" is a term used by Wendy Doniger O'Flaherty in her book Other Peoples’ Myths: The Cave of Echoes to describe mythological figures who succeed in bridging the human and animal worlds to become one with nature, a human animal, only to become trapped between the two worlds, not completely animal yet not entirely human.
[1] Another literary account described this term as a birth defect that results from sexual relations between a human and a shapeshifter in animal form.
[2] It is also a rarely used descriptive term for the so-called feral children.
[5] The term "Mowgli syndrome", however, is not a recognized psychological or physiological malady.
The term originates from the character Mowgli, a fictional feral child from Rudyard Kipling’s The Jungle Book (1894).
