Psycho Jenny had a supporting appearance in Amon: Apocylpse of Devilman with a somewhat more sadistic appearance than usual. She is first seen at the top of Tokyo Tower, watching the violence between the humans escalate. Later on she is seen hanging around Satan the strange dream world that Devilman and Amon battle in.
She is shown to have much more power than before revealed. Above being able to control minds, change reality and fly, she is also shown to be able to hold her own against Devilman.
