Juliet Butler is the younger sister of Butler and a member of the Fowl Manor staff. Like her brother, she is extremely skilled in the martial arts and able to dispatch opponents despite having a size disadvantage. She was also trained by Madame Ko. Unlike Butler, she does not have the dogged seriousness or insuperable military discipline of a proper bodyguard. She failed to obtain the blue diamond tattoo of the bodyguards of Madame Ko's Academy. Fortunately, she no longer needed to have that when she decided not to become a bodyguard, became a professional wrestler and left for America at the end of The Eternity Code.
