Luchs is one of Faust's maiden circuit equipped saber dolls. A skilled tactician and analyst, she is perhaps less convincing at other tasks.
Luchs was originally portrayed in English by Wendee Lee in Animaze's dub of Saber Marionette J Again. She was subsequently voiced by Erin Fiztgerald for the first 9 episodes of Ocean's dub of Saber Marionette J, with Colleen Wheeler taking over from episode 10. Finally, Melanie Risdon played the part in Blue Water's Saber Marionette J to X dub.
