Magic Knight Rayearth II has the delightfully bipolar/dementedly schizo and certifiably psychotic Nova, whose switch every few moments from sweet and childish declarations of affection to a raving engine of powerful magical destruction can be a bit jarring.

She's not around long enough to determine if she's truly a psycho but the squad's pet gay John thinks she's psycho enough from knowing her from the Gay Officers Action League that he convinces Fancy to pull strings to get her re-assigned. Kate's Addiction (1999) follows Kate's obsessive pursuit of former friend Sara up to and including killing anyone who gets in her way. In the opening for the fourth season there's a part where Janette hugs a struggling Louise close and licks her face. Though Joss is a hitwoman who feels no remorse at all, there's no suggestion that this has any correlation with her being a lesbian; indeed, her only real feelings are toward her female lovers and her interactions with them are the most humanizing things about her.In Penguindrum it's implied that Tsubasa stabbed Tabuki out of jealousy once Yuri broke off their affair. note They're likely "political lesbians" - heterosexual radical feminists who "became lesbians" (by which they often just mean "refuse to have sex with men") for ideological reasons.

Additionally, another main character, Miki, initially appears to be somewhat insane (introduced in a prison, then slaughters a bunch of men attacking the prisoners; proceeding to become a hero until her death, only to be brought back to life, only to be merged (in the midst of a lot of lesbian subtext) with Honey to help her defeat the Psycho Lesbian villain Yuki. Although the circumstances of her consuming longing for Hikaru and the origin of both her and her madness (Nova is the physical embodiment of Hikaru's self-loathing after being forced to kill Princess Emeraude in the previous season) are rather unique and in her own case most likely constitute use of this trope as a justified one. The Hays Code-era requirements that "deviant" characters (and that included all gay characters of any gender) must not be made sympathetic or rewarded meant that such characters would almost inevitably be toast before the final credits rolled — and this convention has persisted long after the demise of the Code itself. In Kämpfer, Big Bad Kaede Sakura has the hots for the main character's female form and has an evil alter ego that gets off on sexually brainwashing women.But she unconsciously wishes that Koyomi would disappear, and when the sun goes down her demonic hand takes control over her and tries to grant her wish, which means trying to beat Koyomi to death twice. until you get to her alternate personality, Shii, who is a psychotic, evil man who will do anything to protect the innocent Takaya, while leaving her mostly unaware of his protection. The results of My-HiME's Wham Episode altered many characterizations, including the kind and serene Shizuru who went a bit nuts near the end.

She's a Contractor who Does Not Like Men and shows absolutely no respect for the personal space of her female teammates, who she constantly hits on.This doesn't add up to sex per se in my book, or sexiness/eroticism, but is strictly gonzo, gross-out fetish action. One cuts off the hair of the other in a fit of jealous rage, and then the one who had her hair cut cuts out the eyes of the other as revenge.
