Vanny

Vanny is the main protagonist-villain of Five Nights at Freddy's VR: Help Wanted, a mentioned character in Five Nights at Freddy's AR: Special Delivery and a major antagonist in the untitled game that's coming in 2020. Vanny is a follower of William Afton himself.

History
At a unknown point of time, Vanny became a follower of William Afton, the man who was responsible for The Missing Children Incident over 30 years ago. She also created a white bunny mask.

Five Nights at Freddy's VR: Help Wanted
Vanny at a unnamed point of time is hired for a unnamed company that makes The Freddy Fazbear Virtual Experience alongside Fazbear Entertainment, Incorporated. She witnesses Glitchtrap and follows the instructions of Tape Girl. She turns Glitchtrap into a plushie, making him "safe". (No one will suspect that it's a virus)

Five Nights at Freddy's VR: Curse of Dreadbear
Vanny eventually implements the mask into the VR game, and talks to William in his plushie form. She tells him she made the mask (Hoping he would like it) and that no one suspects anything. She also tells him that she will be ready for the fun.

Five Nights at Freddy's AR: Special Delivery
Vanny eventually is hired for The Fazbear Funtime Service and meets Luis, who is heavily theorized to have a crush on her. She buys three masks, starts searching unnerving things and "help" in the browser, hinting that William is in some way controlling her.

Unnamed Five Nights at Freddy's game in 2020
As revealed in a teaser, Vanny is returning in the unnamed game, possibly as the main antagonist.

Trivia

 * It is theorized that the name Vanny is a combination of Vanessa and Bunny.
 * In the source code, a conversation is found between most likely William and Vanny:

"William Afton: Stay the course. Vanny: I will. William Afton: Focus on my voice. Vanny: I will. William Afton: Don't let anyone lead you astray. Vanny: I won't. William Afton: Have you selected one? Vanny: I have."


 * Ironically, the type of villain Vanny is is the same name she got on voices.com - Reluctant Follower.
 * Since William is now trapped in the VR game and can't do anything, it is possible that Vanny will be the main antagonist of the next games.
 * It is possible that Vanny isn't the only follower - Jeremy had a "Halloween mask" next to him as one of the tapes say, and Tape Girl tells us to do something that will save William, and not kill him.
