Lancer is an enemy Servant in the Moon Cell Holy Grail War in Fate/Extra CCC. She is unique in that she switches between four different Masters as a Lancer-class Servant, Rin Tohsaka, Rani VIII, Shinji Matou, and Hakuno Kishinami, and she later acts as the Berserker-class Servant of Meltlilith. She is one of the Servants of the Protagonist of the Grand Order conflicts of Fate/Grand Order under both the Lancer class and Caster class.
Lancer's true identity is Elizabeth Báthory, the virginal fourteen-year-old aspect that had yet to become the monster Carmilla like her older aspect. She is given the keyword "Dragon's Daughter," related to her nickname "Countess Dracula."
A real person, born in 1560, died in 1614. She was born into the one of the noble families of Hungary, the Bathory family which uses the fang of a dragon as its crest. One of the models for the vampire Carmilla. A wicked woman who bathed in the living blood of more than 600 women in order to preserve her own beauty.
Her personality is considered to be similar to Luviagelita Edelfelt. She self-proclaims herself as an idol and her demonic singing makes her both a rival for Saber in both name and reality. Elizabeth makes a habit of referring to Hakuno, depending on their gender, as either a "little squirrel" if they are female or as a "pig" if they are male when speaking to them.
Lancer also has the capacity to be summoned under the Berserker class, and she switches to it during the events of the story. Her Mad Enhancement is very low, allowing her to retain her reason. There is not much benefit to the skill, turning her Strength and Endurance into a state that is more "don't care about pain" than anything else. She instead has Mental Disorder, a state of the mind falling ill and a mental "super armor" ability. Rather than the common madness added to a Berserker, she becomes incapable of feeling the pain of others and unable to sense the mood in the surroundings.
She displays two different Noble Phantasms, Kilenc Sarkany and Bathory Erzsebet. The first is utilized under the Lancer class, while the second is utilized under the Berserker class. She continues to utilize Bathory Erzsebet as the Protagonist's Servant. Her Territory Creation allows her to build up a prison-castle and that is mainly used in confining girls. According to the records, the master of the castle would capture five virgins a day, execute three for the sake of bathing in blood, and torture to death one as if a pet.
