A Historic Moment in Batgirl Lore: DC Delivered a New Test for Attention-Grabbing Batgirl Fans

The Bat Family’s central rule
The Bat Family’s most important rule is not to kill. Jason Todd and Cassandra Cain have both been removed from the team at different points in DC history after crossing that line or considering it.
A father’s return is teased
Cassandra, now known as Batgirl, has become a key member of the Bat Family. The lessons she learned there shape how she lives, particularly her commitment to the no-killing rule.
The final panel of Batgirl No. 24 teased David Cain with the words, “Next month: David Cain?!” David is Cassandra’s abusive father, who raised her to become an assassin. She is among DC’s deadliest martial artists.
Cassandra’s painful past
Cassandra endured physical hardship and was not taught to speak. She could not talk for more than a decade before breaking free from her father’s control and joining the Bat Family. She later learned to speak while retaining her ability to read body language.
In Batgirl: Forget Me Not, readers learn that Cassandra was once forced to fight a friend. The story presents this as another cruel manipulation by David. The revelations add to the anger she may feel toward him.
Restraint remains her choice
During Tate Brombal’s run of Batgirl, Cassandra has faced repeated temptations to violate Batman’s rule, including threats connected to her mother and her mother’s death. She has not broken the code, and the story says she will not kill her father.
David could still die at someone else’s hands. Jaya Jayesh, Bronze Tiger and Jade Tiger, Cassandra’s brother, are not bound by Batman’s rules. If one of them acts against David, Cassandra’s response is not yet known.
Key points
- The closing panel of Batgirl No. 24 teases David Cain’s possible return.
- Cassandra Cain has repeatedly held to the Bat Family’s rule against killing.
- Her father’s abuse and her deadly training intensify the personal stakes.
- Jaya Jayesh, Bronze Tiger or Jade Tiger could act against David.
