Mr. Whiskers (Frankenweenie)

Mr. Whiskers is an antagonist in Tim Burton's 2012 feature film Frankenweenie. He is Weird Girl's pet cat and is supposedly capable of psychic premonitions.

Description
Mr. Whiskers is Weird Girl's beloved pet cat. He has white, fluffy fur and large eyes. Weird Girl claims that whenever he dreams about someone, something "big" happens to that individual. Mr. Whiskers is usually quiet and has a tendency to stare unblinkingly at people, much like his owner. However, he seems to enjoy taunting the neighborhood dogs, such as Sparky. The one person he seems to show any actual affection towards is his owner, a sentiment she readily reciprocates.

Transformation
During the events of the movie, Victor's classmates attempt to recreate his miracle of science by reanimating animals of their own. For Weird Girl's experiment, she attempts to resurrect a dead bat that Mr. Whiskers brought to her. However, Mr. Whiskers couldn't resist chewing on the deceased bat and, as a result, was electrified when lightning struck during the experiment. The result was Mr. Whiskers becoming fused with the dead animal, creating a horrific, undead cat/bat hybrid. In this state, Mr. Whiskers seems to have all but forgotten his past life and violently lashes out at anyone or anything in his general vicinity.
