The Woman in White

"Don't you dare!"

- The Woman in White's most famous quote

"The Woman in White" (real name: Michelle Crane), also known as "Mater O Mortis" ("Mother of Death" in Latin), "Mater Mortis", "Mother of Parker Crane" (or "Parker Crane's Mother") and "Mrs. Crane", is the mysterious and malicious ghost of a woman in a white dress who is the mother of the Bride in Black and the main antagonist of the 2013 supernatural horror film sequel Insidious: Chapter 2.

She was portrayed by Danielle Bisutti who also played Nika's sister Barb in the Child's Play sequel Curse of Chucky.

History
She abused her son Parker by dressing him as a girl after her husband left them. The Woman in White originally wanted her son to be a girl. In his adult life, she forced him into becoming a serial killer, slaughtering 15 women in the process. After her death, she haunted the Lamberts' house and wants to kill the family. At the end of the movie, she was defeated when the Lambert family's dear friend and powerful psychic Elise used a rocking horse to hit her, putting an end to her reign of terror.

Personality and Traits
An elegant woman dressed in a long white gown. It is the stern and violent ghost of Parker Crane's mother, who spent a lifetime abusing her own son since his childhood, unhappy that nature provided her with a son rather than a daughter, and responsible for triggering his killing spree. She pressures Parker, now possessing Josh's body, to kill the Lamberts, convincing him that it is the only way for him to prevent his host's body from decaying.

Trivia

 * She shares similarities with Margaret White, Margaret Goodnight, Dahlia Gillespie and Ryan Jacobson's parents (John and Mary Jacobson) who abused or neglected their own children and were also delusional.
 * It is currently unknown how she died when she was human. Possibily, Parker must have killed his own mother for the way she has abused him all those years when he was a child.
 * Her name is revealed to be "Michelle Crane", because before the films release, she was listed on IMDb (Internet Movie Database) and Rotten Tomatoes as "Michelle" as also explained in actress Danielle Bisutti's interview on the movie news website Cinema Chords (sometimes spelled CinemaChords).
