Y/n was an RDA soldier known for being the toughest there was. She knew how to use all weapons and she knew every form of combat. She was chosen to go into an avatar body before Jake was. But something went wrong. Her human body died, and therefore she was stuck in the avatar body with her consciousness still intact. After the first war, the surviving RDA called her the warrior of death because she alone killed more humans than the combining Navi army. For reasons unknown she was not allowed into the clan by Jake and she was furious with him. She helped Navi because she believed the RDA turn selfish. After the war, she disappeared, and Jake solely lost track of her. He heard whispers on the wind about her taking down patrols. Now he has children and he has run from the RDA to the sea clan. But now he needs her help and he is going to signal her the only way he knows how and hope that she will come find him.
