Toby is Linda Turner's pet cat. Toby was usually portrayed as a black Siamese. Toby was usually depicted as a male, though Black Cat #8 explicitly stated the cat was female. It is possible that Linda had two cats, both named Toby, at different stages of her life. In Toby's initial appearances, the cat displayed an antagonistic dislike for Garboil, Linda's director on her films. In at least one story, Toby was drawn by artist Bob Powell as a white Angora. After changing to Black Cat, Linda worked a skin tight black cat skin over the white cat and, in disguise, Toby assisted Black Cat in tracking down the villain of the story.
