She is portrayed by Maria Olsen.
She is a Fury sent by Hades to find Percy Jackson, who is suspected to be the Lightning Thief. She manages to infiltrate his school by impersonating a substitute English teacher named Mrs. Dodds. During her first day, she interrogates Percy about a line from Othello, but he is unable to answer due to his dyslexia so she has to ask to somebody else.
Some times later, Mrs. Dodds accompanies Percy's class during a school trip to a museum along with her colleague Mr. Brunner. During the visit, she insistently stares at Percy and finally asks to talk to him in another room. Percy follows her, but she turns back into her true appearance on the top of a scaffolding and attacks him. She manages to grab him before he could escape and threatens to kill him if he doesn't give her the Lightning Bolt. However, Percy's satyr protector Grover Underwood and Mr. Brunner, who is actually the centaur Chiron, enter the room and Chiron orders her to release Percy. Frightened, she drops him and flees through a window.
