I would hate to see your handsome head on a spike if you fail.

–Kelli to Luke Castellan, in The Battle of the Labyrinth.

Kelli is a skilled, senior empousa, disguised as a cheerleader, attending Goode High School.

Percy Jackson and the Olympians[]

The Battle of the Labyrinth[]

Kelli and Tammi went to Goode High School to kill Percy Jackson. Percy beat her trainee Tammi, but Kelli got away easily since she was a senior empousa. She stayed with Luke.

In Percy's dreams, Kelli always sensed that he was watching. She tries to bite him every time, causing Percy to wake up.

She then helped catch Percy, but she died in Daedalus' workshop when Annabeth stabbed her with her Celestial Bronze knife while trying to stop Percy, Nico, Annabeth, Rachel, and Daedalus from getting away on Luke's orders.

The Heroes of Olympus[]

The House of Hades[]

Kelli and a group of other empousai are walking towards the Doors of Death. Kelli talks about how when they get to the mortal world she wants to personally kill Percy. Eventually, Percy and Annabeth defeat Kelli and the empousai, with the help of the former Titan Lord of the Underworld, Iapetus (now known as Bob).

She may have been among the empousai who confronted the rest of the Seven in the House of Hades, using their charmspeak to counter Piper McLean's though that is unlikely because she was killed very recently.

Appearance[]

Kelli is an empousa, who are the servants of the goddess Hecate. In true form, she has completely white skin, flaming hair, fangs, one bronze leg and one donkey leg, and red eyes.

When in human form she appears as a pretty African American girl with curly hair. Percy describes the hair as "curly hair like Medusa's".

Personality[]

While pretending to be a normal cheerleader, Kelli is an alluring valley girl, but is cruel and merciless in her true form to the point where even Luke Castellan was upset at her lack of morals after it was revealed she murdered a young boy in Seattle. She also has a crush on Luke, describing him as "handsome".

Abilities[]

  • Seduction: As an Empousa, she can put men under her spell so she can feast on their blood.
  • Charmspeak: As an Empousa, she can charmspeak in order to attract her mortal victims.
  • Shapeshifting: As an Empousa, she can change from her human form to their true form.
  • Mist Manipulation: As an Empousa, she can manipulate the Mist.
  • Metacognition (limited): She is also able to sense demigods watching her in their dreams as she scared Percy out of his.
