Frieda Reiss (フリーダ・レイス Furīda Reisu?) was Rod Reiss' eldest daughter and Historia's oldest half-sister. She had the power of the Founding Titan and was the Queen of the Walls from 842 to 845. Frieda was tall and had long, smooth, dark hair; stopping well past her shoulders. Frieda had large blue eyes and a rounded face, and she appeared to be well dressed, given that she was a member of the royal family, but was usually seen in simple dresses or skirts. Frieda's Titan form had shoulder length black hair that hung loosely around her face. She had noticeably large dark eyes; as well as a somewhat skeletal nose. Her torso had a defined muscle lining and she had a feminine form much like the Female Titan's, unlike most Titans. Like others with the power of the Titans, she was physically fitter than Pure Titans. Frieda tended to be a good and caring person. She liked to walk and look after the peasants. She loved Historia to the point that she erased her memories in order to protect her.
