Grace Choi's history is explored in the "Outsiders: Most Wanted" arc, in which it is revealed that she was previously the victim of a
prostitution ring. Upon reaching puberty, Grace used her then-nascent
metahuman powers to escape, and spent the next several years living independently, until her recruitment into the Outsiders. In her first appearance in
Outsiders (vol. 3) #1, Grace is working as a bouncer for Chaney's, a nightclub in
Metropolis that is primarily frequented by metahumans.
Roy Harper recruits Grace into his iteration of the Outsiders, convincing her that being part of the group will pay her three times more than her bouncer job.
One Year Later Grace Choi remains a member of the Outsiders, and assists in toppling the regime of
Mali. She gets along quite well with the team's newest member,
Captain Boomerang, and the two have been involved in the somewhat questionable interrogation of some soldiers, involving torture. It has been revealed that Grace has been secretly involved in a relationship with Thunder (Anissa Pierce). After an unsuccessful mission in
North Korea involving
Checkmate,
Nightwing hands over the Outsiders to
Batman, who elects to decide on his own roster culminating in DC Comics' relaunch of the
Batman and the Outsiders title. Grace features in the
Amazons Attack! limited series where during an attack on the
United States by the Amazons, she encounters the
Bana Amazons. One of its members tells her that she is actually part of their tribe, the explanation for earlier allusions by others to "her kind". In the aftermath of the war, Batman assigns
Wonder Woman and Grace to a cleanup mission which serves as an audition for his new Outsiders roster. Grace identifies herself as half-Amazonian and displays a deep knowledge of
Bana-Mighdall's history. Diana and Grace end their joint mission describing each other as cousins. Pleased with her performance, Batman welcomes Grace as the final member of his Outsiders. Despite being angry that Thunder "washed out" during Batman's try-outs and has been excluded from the team, she accepts. She then invites Thunder back onto the team without Batman's permission. Following
the apparent death of Bruce Wayne, the Outsiders fall into a trap set by
Simon Hurt, and most of the team members are severely injured. The group is disbanded shortly thereafter, and is replaced by a new team of Outsiders. Following her departure from the Outsiders, Grace is shown in a live-in relationship with Anissa, with both being semi-retired. When
Black Lightning arrives at Grace and Anissa's apartment with his small band of fugitive heroes, Grace comes to his aid and helps fight off the attacking members of the
Justice Society of America (JSA). In the ensuing battle, Grace renders
Stargirl and
Mister America unconscious, telling them not to threaten her "in-law". After the battle with the JSA, Grace and Thunder agree to join Black Lightning's Outsiders, who are tasked by
Amanda Waller with traveling to
Markovia and capturing
Geo-Force. Following a battle in Markovia, both teams of Outsiders are disbanded by Batman, and the individual heroes return home. ==Powers and abilities==
