OVA
Description
Psychogenie, alias Psycho Jenny, is a demon appearing across multiple works within Go Nagai's universe. She serves as a key operative for Satan, demonstrating unwavering loyalty to him. Her signature appearance features an androgynous large head with flowing hair (varying pink, red, or blonde), gray skin, golden eyes, thick black lips, and small attached arms and legs. Some depictions add features like a torso on her back or exposed breasts.

Her most frequent ability is potent psychic manipulation, encompassing memory alteration, mass hypnosis, vivid terrifying illusions, reality warping, and telepathic communication often appearing in victims' dreams. She levitates and flies using telekinesis. Her psychic power can block attacks from formidable demons like Amon and influence large human groups simultaneously.

Across Devilman narratives, she performs critical tasks for Satan: erasing his memories to facilitate his infiltration as Ryo Asuka, psychically projecting the demons' past through the Demon Mask to manipulate Akira Fudo and Ryo, and actively hindering Akira's efforts during demon invasions.

In Devilman Crybaby, she influenced Ryo Asuka from childhood. After raising him following his human rebirth, she acted as his secretary, assisting daily and driving for him. She prevented Zennon's demons from attacking Akira, citing Satan's wishes. Later, she traveled to Peru to retrieve Ryo once he regained his memories as Satan. During the final battle against humanity, she fought alongside Satan using her psychic powers until shielded humans wielding specialized jet swords killed her.

Within the CB Chara Go Nagai World OVAs, Psycho Jenny appears in a super-deformed (chibi) form but retains her characteristic personality and powers. She informed Ryo Asuka about placing Amon's soul into Kaim, commented on preferring Satan's form over his human guise, teleported Miki Makimura to the Violence Jack dimension on Satan's orders, and questioned Jack about Satan's whereabouts.

In Violence Jack, she served as one of the Nine Dragons under Zubaban, employing her psychic illusions against Jack, including distraction through nudity. She survived the town's destruction by escaping with other Dragons.

Her personality is manipulative yet charismatic, capable of cruelty, effectively exploiting victims' fears and desires. She exhibits deep understanding of human weaknesses. Fiercely devoted to Satan, she expressed confusion over his attachment to Akira Fudo and held disdain for humanity. Despite often sadistic actions, she displayed moments of non-violence, such as allowing Devilman Moyuru Koda to join Satan's forces unharmed.
