Catwoman's Whip

Catwoman's Whip is an assortment of bullwhips and cat o' nine tails, always used as a gymnastic equipment.

History
She can use it as a whip to attack or a grappling hook to grab objects she wants or ledges she can swing from. Highly skilled with her specialized whip, she uses the bullwhip combined with cat-o'-nine-tails, and the whip was capable of astonishing roughage.

She wields both a standard bullwhip and the cat o' nine tails with expert proficiency. She uses the whip because it is a weapon that the user must be trained to use, and therefore it can not be taken from her and used against her in a confrontation. She can also be seen using a pistol against people if her whip is taken from her.

The original owner was Selina Kyle, but due to her absence, Holly Robinson was passed on the cowl of being Catwoman. Trained by both Wildcat and Catwoman, she fit the suit and had the skills, but lacked the experience the original Catwoman had. Only after time, Selina took back the mantle to protect Holly.

Trivia
The 2008 Warner Bros. video game, Batman: Arkham Asylum showed the whip and goggles as a riddle. Only in Batman: Arkham City, did one experience the whip as a escape weapon and combat weapon. Catwoman starts out with the whip, firsthand, without even getting her bolas and caltrops yet.

Starting with Julie Newmar, she was the first actress to use the whip in the Batman film franchise, and so far, the last actress was Halle Berry. It's unknown if Anne Hathaway will be equipped as well.
