Psycho Jenny was a female demoness. She resembled a massive, mostly human female face, with small sharp teeth and massive yellow eyes with red pupils and expressive eyelashes. She had a massive mane of long hair and human-like arms and legs sprouting from her head.
While never expressing her psychic ability, it can be inferred that the illusions caused by the Demon Mask that was donned by Akira Fudo and Ryo Asuka, were a product of Jenny's illusions. Likewise, Akira's later nightmare of Zennon could also be a part of Jenny's magic.
- Had the OVA series continued, it is likely she would have appeared in proper form.
