OVA
Description
Sister Jill serves as the primary antagonist in *Re: Cutie Honey*, leading Panther Claw. Created as the prototype android for Honey Kisaragi by Dr. Kisaragi, structural instability led to her deactivation. Another scientist's reactivation triggered a rampage resulting in Dr. Kisaragi's death, establishing her as Honey's enemy. Her goal involves societal unrest and locating Honey to fuse with her, achieving immortality and eternal youth. Analyzing Honey's memories shifts Jill's objective to destroying human emotion and civilization to spare others Honey's confusion. During their final confrontation, Honey attempts fusion, but Jill asserts her independence, choosing death over merging and abandoning her plan.

Physically, Jill appears as a fair-skinned woman with silver hair, typically dressed in a red velvet dominatrix-style outfit. Her primary weapon is a whip generating phantom hands to restrain or attack. She creates puppets using nanites similar to Honey's "I-System," including Panther Claw members and her butler. After capturing Honey, she fuses her with the "Jill Tree," transforming it into a demonic entity to unleash destruction.

Her background and traits vary across the franchise. In the original manga, she is Panther Zora's pet panther, granted human form and immortality. She reincarnates by feeding on women's flesh to assume their appearances while retaining blonde hair and gold eyes. She wields a whip with lethal precision and injects "alteration cells" into humans to create Panther Warriors, controlling them utterly—even forcing suicide for disobedience. She harbors unacknowledged romantic feelings for Honey.

In *Cutey Honey 90s*, Jill resurfaces 30 years after her initial defeat, reincarnating via a panther form that mauls a woman to assume her body. She rebuilds Panther Claw to pursue revenge against Honey but is killed again, with Panther Zora implying her eventual return. *Cutey Honey Tennyo Densetsu* confirms her recurring resurrection, now emerging from another dimension to continue her conflict with Honey.

For *Cutie Honey Flash*, Jill acts as a secondary antagonist and Panther Claw executive. She kills Hayato Hayami, inciting his son Seiji's enmity, and interferes with Dr. Kisaragi's experiments to steal the "Airborne Element Fixing Device." Defeated early, she revives in later episodes to target Honey again, culminating in a final defeat during Honey's wedding.

In *Cutie Honey Universe*, Jill leads Panther Claw disguised as Inspector Genet, an ally to Honey. Her appearance features blonde hair, a purple mask, and a red suit with a whip resembling a tail. She is described as charismatic yet sadistic.
