This Daimon appeared in a flashback in the episode The Bond of Destiny! The Distant Days of Uranus. This Daimon took possession of a living human. It attacked Haruka but was held off by Sailor Neptune. It was destroyed by Sailor Neptune, and the person being possessed by it survived.
Trivia
This Daimon closely resembles the Daimons from the original manga in both its appearance and its acquirement of a human host rather than an inanimate object.
While this creature was never specified on screen to be a Daimon, one can assume so because of its uncanny resemblance to the Daimon in the manga.
