Carnage and Diablo are Natashas undead pets. They assist her in everything she does, and she is never seen without them beside her or on her shoulders and head. She uses them to speak with dead felines to see if they want to be brought back and they link her to deceased felines such as sabertooth tigers to allow her to change into their forms, though this takes alot fo energy.
Pia is also a part of her acts, but more backstage most of the time. She can be used as a pretty assistant in demonstrating things while Natasha is in a feline form, and after big performances involving enct cats, she is a quick snack to help replenish Natashas energy, since she is a vampire after all.
