Batman: The Animated Series first premiered in 1992. In the show, Batman would surround himself with a group of allies to help him in his efforts to eliminate crime from Gotham. The likes of Dick Grayson, Alfred Pennyworth, and Barbara Gordon rounded out Batman's supporting cast.

Batman: TAS would branch out into a larger shared universe, including sequels in Justice League and Batman Beyond take place within the same animated reality. Barbara Gordon plays a key role in both TAS and Batman Beyond, going through a number of key changes in-between the two shows.

10 She Retired As Batgirl

Batgirl - The New Batman Adventures

Barbara was Batgirl for years and saw a lot of horror as a result. She stuck by Batman's side when Dick Grayson quit and walked away. She continued her superhero life after seeing what the Joker did to Tim Drake. She continued helping Batman as everyone else around him quit the superhero life.

Eventually, she decided to move on. She realized that there wasn't much of a future in being Batgirl. Despite all the good she'd done in costume, that wasn't the life she wanted forever. So, she retired as Batgirl.

9 She Joined The Police Department

Barbara's life as a superhero gave her a chance to help people. She had been raised with a clear sense of right and wrong since her father was a cop. Not much is known about her early career in the police or what kind of job she had with the police. She could have started as a traffic cop or used her computer skills to help in a technical capacity. There's no way of knowing what her father would have thought about her following in her footsteps.

8 She Was Shot

When Batgirl visited the Batcave in Batman Beyond, she got a chance to meet Terry McGinnis. She was surprisingly cold to both Terry and Bruce. Terry watched as she went to examine her old costume.

While looking at her costume, she remarks that the bullet holes are gone. Batman tends to only put costumes on display when they are no longer being used. Barbara was likely shot right before she chose to retire. This is a reference to The Killing Joke, the comic where Barbara is forced to quit being Batgirl after being shot by the Joker.

7 Her Life As Oracle

A canceled episode of Justice League Unlimited would have featured Barbara in the role of Oracle. In the episode, Barbara would have been recovering from a serious injury. When Langstrom and his Man-Bat army start causing trouble, Batman orders Barbara to stay away, giving her more time to recover.

Barbara would have attempted to recruit Nightwing to help her with the issue, but he would be unavailable. She would have then turned to Huntress and Black Canary to help her stop Langstrom, with her acting in an Oracle-like capacity. The episode couldn't be made because the rights to Batgirl were unavailable, however.

6 She Broke Up With Bruce

In one of the most disturbing scenes within this universe, it is revealed that Barbara and Bruce had been in a relationship. In comics, the relationship is revealed when Barbara tells Bruce that she is pregnant with his child. She would eventually lose the child but continue the relationship. She tells Terry that the relationship was like dancing a ballet. She also reveals that she ended things because Bruce didn't seem to want anything more than being a superhero.

5 She Ended Things With Dick

Barbara and Dick dated for a while within the animated universe. Their relationship was pulled directly from comic book canon. Barbara tells Terry that their relationship wasn't anything serious. She dismissively states that they dated when they were in college.

At one point, she was involved with both Bruce & Dick at the same time. She seems to have chosen Bruce over Dick, which may have further strained things between Bruce and his former ward. Her feelings for Bruce helped her walk away from her best-known relationship.

4 She Got Married

Barbara walked away from being a superhero and dating her coworkers. She would move on from the hero's life completely. She would eventually meet the man she would one day marry. In typical Barbara fashion, she once again got involved with a man she worked with.

Sam Young was a lawyer and worked as a District Attorney. The two would have worked together putting criminals in prison. It is unknown if Sam and Barbara ever had any children. It is also unknown if Sam ever learned about Barbara's life as Batgirl.

3 She's Irreplaceable

In the comics, Barbara is just one in a long line of people who use the name Batgirl. Stephanie Brown and Cassandra Cain later join the Bat-Family under the identity of Batgirl. However, the animated universe makes Barbara the only Batgirl.

In Batman Beyond, Bruce has lost nearly all of his old allies. Unlike in the comics, the Bat-Family only shrank as time went on. Once Barbara leaves her role as Batgirl, there is no one to fill in for her.

2 She Took Over Her Father's Old Job

Barbara's father, Jim Gordon, was one of Batman's allies. Jim was the police commissioner, a high-ranked officer. Barbara would eventually take over as Gotham City's police commissioner.

Barbara might have been the best successor for her father, but she would have had to work her way up to the position. There would have been countless hours of dedication to earn that title. It probably took years for Barbara to step into her father's old role, and there is a chance he didn't get to see her fill his shoes.

1 She No Longer Trusts Bruce

Batman Beyond Old Man Bruce Wayne

There was a time when Bruce Wayne was an incredibly important person in Barbara's life. She repeatedly had to put her life in his hands. There was a deep level of trust between Barbara and the rest of the Bat-Family. By Batman Beyond, it is clear that she no longer trusts Bruce. There was never a clear reason why Batman completely lost her trust, but it was clear that her lack of trust carried over to Terry McGinnis.
