Lara Tybur was an Eldian noble living in Marley and secretly the inheritor of the War Hammer Titan.
Lara was a lady of regal appearance, standing relatively tall with dark eyes. Her hair was dark and slightly wavy, kept behind her head in a bun, and her facial features were small and gaunt. She wore a black and white dress with long, puffy sleeves and an embroidered white collar.
Very little can be seen of Lara's personality, but it can be inferred that she shared her brother's radical views regarding Paradis and Eldians as a whole. She participates in Willy's plan to use his own life and the lives of the people of Liberio to draw out and kill Eren Yeager, and is able to keep a cool head and remain focused on her mission even after her brother's death.
