Elizabeth Bathory, born in 1560 into Hungary's noble Bathory family, appears as a pre-monstrous incarnation before her transformation into the vampire Carmilla. Her family's dragon lineage, symbolized by a dragon fang on their crest, manifests in her summoned form. Historically infamous as the Blood Countess, she bathed in the blood of over 600 women to retain beauty, viewing non-nobles as subhuman due to her upbringing. Her reign ended with imprisonment in Čachtice Castle, where she died in 1614. She manifests with pink hair, light blue eyes, dragon horns, fangs, a tail, and scattered pink scales. Her cyber-goth-loli attire includes detached sleeves and knee-high spiked shoes, and she wields a lance doubling as a microphone stand. Across ascensions, her outfit evolves: her second form features a monochrome plaid skirt and corset, while her final form adopts a Sweet Lolita style with layered frilly skirts, pearl-like scales, and a large decorated hat. Her personality blends nobility, cruelty, and naivety. Self-identifying as an idol, she displays inhuman manners but occasionally shows compassion by aiding allies or sparing enemies. She rejects being called a "good person," considering torture natural due to her upbringing and the Mental Disorder skill that dulls empathy. She addresses females as "little squirrel" and males as "pig." Abilities stem from dragon blood and legend. As a Lancer, her Noble Phantasm *Kilenc Sárkány* amplifies her voice ninefold to inflict sonic damage and control weather. As a Berserker, *Báthory Erzsébet* summons Čachtice Castle as a stage, merging cursed energy with her singing for area attacks. Skills include *Torture Technique* (lowering enemy defense) and *Charisma* (boosting ally attacks), later enhanced to *Sadistic Charisma* for stronger female ally support. The *Innocent Monster* skill distorts her form with dragon traits, granting limited-power abilities like *Dragon Breath*. She possesses *Magic Resistance* and a reverse scale near her tail; its exposure causes extreme embarrassment. In *Fate/Grand Carnival*, she appears episodically: one segment depicts her working as a Kabukicho hostess at Club M to earn QP, where her volatile temper sparks comedic chaos; another features her in "Oni Cure."
