Caltrops are sharp, metal jacks that could be dropped and used as a trap, when enemies tripped and fell down when they stepped on them.

Arkham Knight Incident
- Like most DLC character gadgets, Catwoman's Caltrops are real life weapons.
- In Batman: Arkham City, the player can only use the gadget three times, and they don't replenish unless the Checkpoint is restarted or completed. In Knight, they replenish over time, presumably to balance her lack of climbable ceilings.
