Arkham City Incident
After Catwoman decided to break into Hugo Strange's Vault, she knew that she needed her weapons to get the task done. Catwoman headed over to her apartment to get her Caltrops and Bolas. Like Batman's Batarangs, she seemed to be able to carry an arbitrarily large amount of weaponry.
Arkham Knight Incident
The Bolas worked identically as they did in Arkham City.
- Like other ally gadgets, Bolas are real life weapons.
