Barbara Gordon (Earth-9: Post-Crisis)

Commissioner Barbara Gail "Barb" Gordon is the former vigilante known as Batgirl and the commissioner of the Gotham City Police Department.

Relationship with Dick Grayson
In 2015, Barbara Gordon orchestrated multiple burglaries and was confronted by Robin in an art museum. She then revealed her identity to Dick and convinced him to work together in order to remind her father about the failing security in Gotham. The duo then infiltrated another gallery, only to find themselves in front of a pair of criminals. When the female thief threw a projectile at Dick, Barbara tackled her and the weapon killed the criminal's partner, allowing Barbara and Dick to escape.

Batgirl
At some point after 2015, Barbara Gordon became the vigilante Batgirl and worked alongside Batman and Robin. She was then paralysed when Joker shot her, causing her to lose a leg and permanently requiring a wheelchair.

Later, Barbara met Jason Todd, the new recruit for Robin after Dick's leave to be more independent.

Death in the Family
In 2021, Barbara met Dick Grayson once again after Jason Todd's death. They then visited Bruce Wayne, talked about their past as vigilantes and demanded Bruce not to recruit a new kid as Robin. As the conversation grew tense, Barbara left and told Dick to prevent another Robin from happening.
