Jackie Tristan

is a member of the mysterious organization, Xcution.

Appearance
Jackie is a tall woman with short dark hair. She wears a dark long-sleeved shirt.

The Lost Substitute Shinigami arc
Jackie is present along with Yukio and Giriko Kutsuzawa in the Xcution's main headquarters when Kūgo Ginjō brings Ichigo Kurosaki into the building for him to join them. After Kūgo explains to Ichigo who they are, and after Riruka Dokugamine brings in Yasutora Sado, Ichigo agrees to help the Xcution with their goals, which relieves Jackie, Giriko, and Yukio.

Ichigo later returns to the Xcution for training. When Riruka enters with a doll house, she immediately starts fighting with Yukio. Jackie breaks up their fight and asks Riruka to explain the Doll House to Ichigo. Riruka complies, arguing that she didn't need her to remind her. As Ichigo trains inside the Doll House, she asks Kūgo if he will be alright. Kūgo replies that he does not know. Later, while Riruka is eating, Jackie notices that Riruka is worried and asks why she does not help him. Riruka denies being worried and tells her that if he dies from the training, then it will just show how limited his potential was. Jackie asks if she is certain, inquiring if she has a timer on the doll and pointing out that fifteen minutes is almost up. Yasutora Sado returns to Xcution's hideout and asks what the Doll House is. Jackie tells him that Ichigo is doing his Fullbring training in it, surprising him. Later, Jackie asks Kūgo if he's drinking because he's happy that Ichgio's training is going well, which he denies. She also appears shocked that Ichigo knows of the existence of another Fullbringer. Jackie allows herself to be placed inside Riruka's fish tank for Ichigo's next training session, where she confonts him when he arrives and introduces herself properly to him, ready to battle.

Jackie waits for Ichigo to attack her, but he replies that he's waiting for her to activate her own Fullbring. Jackie then tells Ichigo to think of their training session as more of a battle rather than training and activates her Fullbring, Dirty Boots. When her Fullbring is finished activating, she moves at high speeds and tries to attack Ichigo, but he manages to evade her strike, much to the surprise of both of them. Ichigo asks about Jackie's change of clothes and she tells him that it is a part of her Fullbring, but she refuses to tell him her Fullbring's ability. Ichigo decides to treat it like a fight after all, thinking that he might find out while they're fighting.

Fullbring

 * Jackie activates her Fullbring by rubbing her boots together. Upon activation, her boots extend further up her legs, armor is generated on her shoulders and forearms, a scarf is generated around her neck, and a dark-colored hat appears on her head with a cloth hanging in front of the right side of her face.


 * Enhanced Speed: Jackie's speed increases immensely, as she is able to move quickly enough to vanish from her opponent's site and launch a surprise attack at her opponent from behind.


 * Enhanced Strength: With Dirty Boots, Jackie is able to use physical attacks strong enough to create tremors in the ground upon striking it.
