Thea is a playable character in Fire Emblem: The Binding Blade. She is the middle sister of Juno and Shanna. She can be recruited by either her employer, General Klein, or Shanna, but only once Klein is recruited. She has problems with showing any form of positive emotion towards her younger sister in public, and easily becomes embarrassed. This could also be because she does not want to make herself look like a fool in front of Klein. Thea is also very protective of her older sister, Juno, and worries about both her and her baby. After the war, she becomes the new flightleader.
