History Sandbox / MonsterDevilman

** [[TreacherousAdvisor Lan Asuka]], [[AdaptationalVillainy unlike]] in [[Manga/DevilmanLady the manga]], is revealed to have been manipulating protagonist Jun Fudo the whole time. First awakening Jun's powers as a monstrous Devil Beast by letting another attack and try to rape and eat Jun, Asuka forms [[InLoveWithYourCarnage a lust towards Jun's alter-ego of Devilman Lady]] and constantly toys with her and her friends. Asuka [[ManipulativeBastard manipulates conflicts]] throughout the series between humans and the mostly peaceful Devil Beasts, resulting in camps formed to hold and exterminate all the Devil Beasts. Asuka lures Jun to her and reveals her true intent: Despising the world and all in it, Asuka, who had been born both male and female, wants to use Jun to become [[AGodIAm a new God of the world]]. Asuka paralyzes Jun and then, demanding Jun "prove" her love for Asuka, rapes a traumatized and terrified Jun before informing her [[YouHaveOutlivedYourUsefulness Jun had been born solely for her and would now die for her]] before disposing of her. When Jun returns, the newly deified Asuka mocks her, saying being perfect was too good for a "hideous creature" like Jun before trying to destroy her in their final battle. Valuing her own ego above all else, Asuka is a manipulative and cruel embodiment of lust and selfishness.
