[1] Choi is introduced as a young Asian American woman using her powers of superhuman strength, healing, and enhanced durability to make a living as a nightclub bouncer, who is reluctantly recruited by her superhero acquaintance Roy Harper to join his new crew of heroes, the Outsiders.

In the course of their adventures, Grace comes to take pride in her work as a vigilante, and discovers that she is descended from a tribe of Amazons, explaining her better-than-human abilities.

Grace Choi is a 7 foot tall Asian-American woman with metahuman strength who sports tattoos styled along Pacific First Nations lines on both of her arms and a circular sun design around her navel.

Grace's history was explored in detail in the "Outsiders: Most Wanted" arc, in which it was revealed that she was one of the surviving victims of a prostitution ring that exploited abducted and runaway children as its "merchandise".

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.

Grace was briefly shown working alongside the Birds of Prey when they attempted to stop a group of villains from killing the Secret Six and taking Neron's "Get Out of Hell Free" card from them.

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.

[8] Grace Choi possesses metahuman levels of strength, heightened durability and endurance, as well as regeneration and increased healing.
