: You may be thinking of LadyDevimon , a popular female-presenting demon Digimon. While she is typically depicted as female, the "Devimon" lineage starts with a male-coded demon, leading to fan discussions about gender evolution within the digital world.

: Instead of a static physical appearance, the demon might change their gender presentation based on their current mood or the person they are interacting with.

: Give the character a voice that harmonizes both high and low tones simultaneously to emphasize their non-human nature.

: In the Warhammer universe, the Chaos God Slaanesh and their demonic followers (like Daemonettes ) are explicitly described as having an unsettling, "hermaphroditic" beauty, often featuring a mix of masculine and feminine anatomy. 3. Pop Culture & Media

: Many cultures have legends of spirits or demons that can shift between genders or possess both. These are often used to represent chaos or a break from the "natural" order of the human world. 2. Fantasy & Gaming (RPG) Concepts

: While often called a deity or an idol, the Baphomet is the most famous occult figure representing "as above, so below." It is traditionally depicted with both male and female physical attributes (such as breasts and a phallus) to symbolize the union of opposites.

: In many modern RPG settings, such as Dungeons & Dragons , certain demons are described as "androgynous" or "fluid." An entity might be a Succubus one moment and an Incubus the next, possessing traits of both to better tempt or deceive their targets.
