Nick Walker

Nicolas "Nick" Andrew Walker is the main antagonist and centerpiece of the Peekaboo franchise. He was an almost completely silent or at least while he was in costume, and is a seemingly unstoppable killing machine.

Nick has killed around 150 people and 20 animals. All of which he did for fun.

Early History
Nick grew up with his younger sister Rebecca, to a redneck family. They were abusive alcoholics, and while Nick would always try to protect his sister, it would only get him beaten more. As a kid, he wore a bunny mask for a Halloween that he made out of a burlap sack. It was pretty big and didn't really fit him, but he wore it out for trick or treating anyway. When he got back, his father got drunk, stole his candy, and beat him some more when he tried to get it back. Despite his abusive parents, Nick was an honor student with constant straight-A's and even got into college with a full ride. Going home to tell his parents hoping they'd be proud, his father beats him and ends up breaking his nose. Nick fixes his nose and gets up to check the house for his sister, not finding her, he takes a kitchen knife and repeatedly stabbed his mother and tied his father to a chair. He put his burlap sack bunny mask on and confronted his father while he was tied to a chair. He asked him if he had ever cared for him or his sister, but since his mouth was taped shut he couldn't answer, Nick stared at him and said: "No... because that's not who you are." Nick then put his kitchen knife into a table behind the chair and picked up a clever. Nick walked over towards his father once again and chopped off his father's hand. He re-picked up the knife and started cutting off his father's fingers one by one. He then stabs his father in the heart before slitting his throat and he starts cooking his dead parents and eats them and afterward's burns the house down. This one event makes him realize he enjoys killing and eating people but after that night, his sister was put up for adoption as she was not of legal age yet. She was adopted by their aunt and he went to college.

Peekaboo
In the first peekaboo film, Nick is in the college library when he first meets Stacy. She asks him if she can read the book he was reading after he's done, smiling he agrees and just hands it over as he said he says he read it already and asks to see what she's been reading.
