Crystal's Mom

Crystal's Mom is a villainess from Cry of the Cat, the first book of the Goosebumps Series 2000 series, as well as the two part TV episode under the same title.

On TV, she is played by Kate Hennig.

Crystal's mother (whose name isn't revealed) is an evil scientist who used cats as part of her experiment:  an attempted cure for a deadly virus. Crystal's mom stated that she used cats because they have a better immune system, but her experiment still failed and all of the cats were killed except for Rip, who became a monster feeding on human life force. Crystal's mom was a repeated victim of Rip's attacks, constantly scratching her to slowly take away her life force and turning her into a villainous half-human, half-cat creature. She willingly did this to prevent Rip from going after Crystal, and in her appearance in Part 2 of the episode, the villainess planned to sacrifice Alison (the main protagonist) to Rip. After Alison and Ryan destroyed Rip for good, Crystal's mom regained her full humanity, and was grateful to the protagonists for saving her and Crystal.
