Mara Jade was raised as a servant and assassin to Emperor Palpatine and became a high-level Force-using operative. As an Emperor's Hand, Jade carried out the Emperor's bidding, killing Rebels and corrupt Imperials alike with cold professionalism, even as a young woman. As Palpatine's assassin, she received top-notch training from experts in a variety of fields as well as training in the Force. During the Galactic Civil War, Mara Jade proved herself skilled in a variety of fields; she was a good pilot and mechanic and trained in the use of both a blaster and hand-to-hand combat even without relying on the Force.

Mara Jade should sound like Katheryn Winnick, Scarlet Johansson, Bryce Dallas Howard, Karen Gillan, Bridget Regan, or Heidi Shannon.
