Frieda is a minor antagonist from Attack on Titan. She was given the role as ruler of the walled civilization on the island of Paradis behind the three walls of Maria, Rose and Sina. As a member of the royal Reiss family she was given the Founding titan held by Uri which in turn carried over the king's pacifistic nature, even accepting whatever attack may come from the outside world.

Frieda is a young woman with long black hair and bluish eyes which appear to slightly change to a purple color as a trait of the Founding titan. Her titan form has the basic features of the average human while standing at 15 meters tall, having traits of her regular self having long black hair and same colored eyes but her titan has a fixed scowl.

Given she possesses the strongest of the nine titans, the Founder, she would naturally be able to control any and all other titans which also includes fellow Eldians. This even means altering their memories such as erasing certain ones at will. However, she hasn't gained the experience to wield it properly likely due to lack of a need to use the Founder's power. Like any other shifter she also possesses regenerative power.
