Jacqui Briggs

A close friend to Cassie Cage, Jacqui Briggs is the daughter of Jax and Vera. After Jax was resurrected from being one of Quan Chi's slaves during the Netherrealm War, he became overly protective of Jacqui and wanted her to live a normal life. At some point, Jacqui became a professional kickboxer and eventually competed in the Junior Olympics and enlisted in a training camp. Despite her father not approving her decision to join the Special Forces, Jacqui sees it as her duty to protect Earthrealm and to avenge her father from the suffering he endured from Quan Chi and Ermac.
