*Vanessa A., also known as Vanny, was a follower of Glitchtrap, a digital virus similar to that of William Afton, and is the secondary antagonist of the Cooperative Series of the Five Nights at Freddy's franchise.

She is a minor antagonist of Five Nights at Freddy's: Security Breach. It's revealed in the Princess Quest minigames that she was the main protagonist in Five Nights at Freddy's: Help Wanted, where she was first corrupted by Glitchtrap. In Five Nights at Freddy's AR: Special Delivery, she goes by the name Ness in the e-mails.

Vanessa is a young woman with pale skin, shoulder-length blonde hair, freckles, green eyes, and glossy lips. As revealed in the e-mails in Special Delivery, she used to wear rainbow streak hair extensions, and is seen wearing purple nail polish. Her former co-worker, Luis, describes Vanessa as someone who could brighten up the room in the scrapped e-mails.

While working, she wears a dark gray cap labeled "SECURITY" with a white button-down shirt, two small single-chevron collar pins, simple black shoulder marks and an oval patch featuring a silver police-style badge. This is paired with black oxfords, black slacks and a belt, where she wears a gold-tinted badge on her right hip.

As Vanny, she wears a white bunny costume that has stitching all over it, with a large pink tartan stitching on her left hip. The costume also has a light-tilted blue bow on the chest and its hands and feet have pink paw pads under them. Her bunny mask has a wide, creepy smile with small buck teeth, a pair of long whiskers, small eyebrows, and big glowing red eyes that appear to be spaced out.

In Five Nights at Freddy's: Help Wanted, Vanessa has some uncertainty in her voice when being confronted about her task implying she at first wasn't fully ready to kill victims. However by the time of Security Breach, she had apparently killed at least nine children at the PizzaPlex, as seen in a newspaper article in the Alley Ending for Security Breach.

In Five Nights at Freddy's: Security Breach, Vanny is shown to have a sadistic personality hidden behind a childlike flamboyance. This is shown through her casually and gleefully skipping after Gregory as he runs from her before running with arms outstretched if Gregory is too close. She also happily orders the S.T.A.F.F. Bots to disassemble Glamrock Freddy and constantly laughs as she is about to murder Gregory. Despite this, she is capable of showing fear, especially when her plans backfire. This is evident if Gregory makes the Staff Bots kill her the same way she did to Glamrock Freddy earlier.

As Vanessa, as shown by the e-mails, she has a very stereotypical feminine personality, showing an appreciation for fashion with her rainbow streak hair extensions. She also likes baking, having ordered cupcake cookbooks, and likes puppies, as she purportedly owns a glittery pink journal with pictures of them. However, Vanessa also appears to be very lonely. Luis mentioned that she once ordered chocolates for herself and pretended they were from her imaginary boyfriend, Brad. She is shown to take her job seriously, making an effort to find Gregory to keep him out of trouble and even threatens to have Glamrock Freddy scrapped if she finds out he is helping him cause any type of trouble. She also reveals that she knew Gregory's name via hearing Freddy's voice coming from the Fazwatch. She also claimed that all the other animatronics were aware of Gregory's presence. She is also shown to be hot-tempered at times, as when she finally finds Gregory and takes him to the Lost and Found, she is seen admonishing Gregory for his actions before her face glitches into Vanny.*
