Sergeant Jacqueline Sonya "Jacqui" Briggs is a character in the Mortal Kombat universe, who made her first appearance in the Mortal Kombat X comic series and her playable debut in Mortal Kombat X.

Jacqui (MK11)
A close friend to Cassie Cage, Jacqui Briggs is the daughter of Jackson Briggs and Vera Briggs. 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 (who ripped off Jax's arms during the Outworld tournament).
Jacqui enjoys the time she spends with Cassie but was often annoyed by her friend's lack of hindsight in their youth and is often the voice of reason when the two get into predicaments. During missions, Jacqui becomes very serious and supports Cassie’s leadership. Jacqui is very protective of her family but is easily annoyed whenever her father’s history of being Quan Chi's slave is brought up, as shown when Kung Jin continues to do so. Most recently, she has become romantically involved with Takeda Takahashi, Kenshi’s son and Scorpion’s apprentice.
In Mortal Kombat X she is a Specialist and is promoted to Sergeant by the time of Mortal Kombat 11. In addition to this, it is revealed that Jacqui and Takeda are engaged, through dialogue intros with Scorpion.
An evil version of Kung Jin appears alongside Jacqui Briggs, Takeda Takahashi and Cassie Cage during the Second Battle of Armageddon on the side of Titan Shang Tsung. However, they are quickly dispatched by Titan Kitana.

Shinnok's Uprising[]
It was first brought up by Aiko, due to recalling the Revenant invasion, that Jacqui was born during her dystopian future and Jax had made a tragic, downward spiral afterwards, even becoming one of the Revenants...
Final Kombat[]
It was mentioned by Jax to Sonya and Johnny that her birth is at hand, once Armageddon passed. Several years later, she still became a fresh new face to the Special Forces with Jax as his badass self.
