The King of Fighters character.
Her initial character concept was to be the rival to Ash though developers decided to change her importance into a "leading lady" character. Her earlier design resembled a tougher modern-day equestrian including a short whip-they kept the whip as they liked the idea of short, quick movements. Developers also describe her fighting style as "orthodox with subtle tricks [to it]" despite her minimal moveset.
Elisabeth is the last known remaining Blanctorche, a family of nobles in France who supposedly protect the innocent. She is a childhood friend of Ash Crimson and they were raised in the same mansion together. She used to act as his older sister figure, until a fire burned down the mansion and many of her clansmen to the ground. As the sole member of the clan, she lives with her butler, Jacques, near the remains of her family's home.
She initially invites Nikaidou Benimaru and Duo Lon to France to reveal that she knows of the betrayal of Ron and the burning of the Hizoku village. They inform her of Ash's theft of Kagura Chizuru's mirror and she decides to join them. With the trio banded with the interest to take down Ash, they form the Rival Team and she eventually scolds Ash for seeming to forsake their mission. Though surprised by the youth's new powers, she swears to stop him in her team's ending.
Before meeting with Duo Lon and Shen Woo, she revisits the burned down mansion where she and Ash spent their childhood with a handful of photographs from the area in her hand. During her meeting with her guests, she becomes aware of their intents to join the King of Fighters tournament with her and Ash's location in Paris. Although she just missed him, Elisabeth knows that he was there and fortifies her will to stop him. She reunites with Ash in the final act of the tournament only moments after Ash erases Saiki from existence. She yells her protest to his selfish decision, stating that she wanted to bring Ash back home with her. When he disappears with his apologies, Elisabeth mourns over the only memento he left behind: his headband.
She attacks with a short ranged riding crop. She also uses magical light powers to trick and trap others.
