They say a story is only as good as its villain. In R.L. Stine’s Goosebumps series, there is certainly no shortage of that. In his Goosebumps Most Wanted series, he introduced several villains that not only spooked and scared the reader but made the narrative all the more interesting. The series is composed of ten books from the main series, four from the special edition, and also a standalone novel.

Below are some of the series’ spookiest, most unforgettable, and most wanted villains.

Slappy the Dummy

One of the recurring villains in the franchise, and one of the most popular villains in the Goosebumps franchise, he is a ventriloquist dummy when certain words are spoken aloud. Scribbled on a piece of paper inside Slappy’s jacket pocket are the words ‘Karru Marri Odonna Loma Molonu Karrano’. After he has come to life, Slappy will then try to make whoever it is that brought him back to serve him.

The Haunted Mask

Considered as one of the most iconic antagonists in the series, it is a living mask that aims to possess its user. It serves as the main antagonist in three of the series’ books. The mask was created by a shopkeeper with an ugly face. It was a prosthetic face that is supposed to be beautiful. Made out of human flesh that is supposed to attach itself to the wearer’s face, something went wrong and the mask turned hideous. When the shopkeeper attempted to remove it from his face by carving it out with a knife, it then became the iconic Haunted Mask.

Dr. Maniac

The villain of Robby Schwartz’s webcomic, for some reason, he escaped from the comic pages and into the real world. He can make things fly, explode, heat, cool, and even make them jump out or into cyberspace. He was also taught by the Scorch with the trick of making fire when he rubs his fingers together. As his name suggests, he is mental and greatly insane while thinking that he is funny and he considers the Purple Rage as his sworn enemy.

Murder the Clown

This is Uncle Theo Gordon’s stage name from R.L. Stine’s A Nightmare on Clown Street. When he tried to write Ray a note, Mr. Haha Face caught him and he was then sent to Clown Street. The place is a prison where clowns are tortured by The Frightener.

Mrs. Maargh

She is a vile creature who happens to like human appetizers. Smart and cunning, she always ensures that her secret is never revealed to any adults. While she is very hard to lease, she likes hearing people comment something good about her. She also loves knowing who is at the bottom of her food chain knowing that she will feast on them later on. Victims can escape from her evil clutches though when they can manage to get her into hibernation ether by giving her some hot sauce or by tickling her.
