Gemeni the Succubus
Beautiful but deadly Gemeni is a cunning fiend. Being the queen of darkness she's lives up to her name. Unlike her partner Psycho Morpher, She's equipped with hypnosis, invisibility, intangibility, supernatural strength/speed, power absorption, energy projectiles, including the ability to posses victims. Gemeni's helmet protects her from psyche based attacks even mind control. When she transforms into a human she's most vulnerable but her hypnotic abilities are stronger up-close.
Even though most demons have wings, Gemeni creates artificial wings that transform into different weapons or appendages for her own disposal. With all these tools at her disposal, she is truly the master of espionage.
