Will Blake is the main antagonist of the fourteenth Goosebumps book, The Werewolf of Fever Swamp, and the tertiary antagonist of the Goosebumps film.


The Werewolf of Fever Swamp

Grady Tucker first met Will after Grady's family moved into their new home in Florida. The boys quickly became friends. When Grady met Cassie later on, he learned of werewolves and one most likely existing in Fever Swamp not too far from his house, due to animal killings and a hunter gone missing. Will did not believe in such things and often argued with Cassie that werewolves are not real. As days went by, Grady eventually ventured into the swamp alone with Will. When Will vanished a few minutes after Grady entered the swamp he started looking for him. Then Grady was attacked and bit by the werewolf who he realizes from the facial features is Will. Luckily for Grady before he passed out, Grady's dog Wolf attacked Will and fought him off. After The Swamp Hermit witnessed their fight, he brought Grady home where his father told him what the Swamp Hermit witnessed. Grady had his dad check Will's house, only to find the house mangled and no one living there. After that night, Grady soon learned that Will cursed him when he bit him. With Will gone, he has the swamp all for himself and now goes with Wolf on hunts and explorations in Fever Swamp during full moon nights.

The TV show version of Will's character is slightly different from his book counterpart. In the TV episode, he believes in werewolves and accuses the swamp hermit of being one as opposed to the novella where he scoffed at Cassie's beliefs in them. It is also stated that he killed the Swamp Hermit's wife and children (which was never stated nor implied in the original novella). Grady ran into the Swamp Hermit when his net caught what was the werewolf when he actually caught a deer. The Swamp Hermit is then attacked and killed by the werewolf. When the full moon is obscured during a lunar eclipse, Will partially reverts back to human form. Having become friends with Grady, Will warns him to leave before he becomes uncontrollable again. But the moon becomes visible again and Will begins compulsively howling as he turns back into a savage beast. As Will attacks Grady, but he is not shown biting him like in the original novella. While Will is attacking, Vandal shows up to defend Grady. Vandal knocks Will into the quicksand-acting bog of Fever Swamp and he sank to the bottom. What appears to be his skeleton rises from the swamp some nights later.

General information

Psychical appearance


Will Blake as he looks in How to Draw Goosebumps.

In his human form, Will has the appearance of a twelve years old, Caucasian boy and resembles a football lineman with broader shoulders and a thicker neck. He has dark brown hair, cut very short and it stands straight on top, like a flattop and is swept back on both sides.

In Goosebumps Graphix, he wears a purple and black stripped shirt, dark blue shorts, and blue shoes.

In the Goosebumps movie, his werewolf form wears blue shorts with red and white stripes and damaged athletic sneakers. He also has a heart tattoo with MOM on it.


In his human form, Will is quite friendly and has a fair bit of humor in him, but as a werewolf he is really vicious and will attack any living creature in sight. He has a very strong knowledge of Fever Swamp and its history and he likes exploring the swamp itself. Like everyone else in his neighborhood, he has never fully met the swamp hermit, but he thinks that he is weird. He is often annoyed with Cassie constantly talking about werewolves and thinks that she is weird too. Up until Grady found out, no one ever suspected Will of being the werewolf that terrorized Fever Swamp. Whether Will knows that he is a werewolf or not is in question.

Video Games



  • Although he appears to be about twelve-years-old, it is hinted that Will may actually be much older. At one point in the television episode, he told Grady that a werewolf will never get a day older as long as it keeps finding victims.
  • In the Goosebumps movie he is incapacitated when Champ bites into him with his "silver teeth fillings" In reality silver fillings are made of Amalgam and are only called that due to its silver appearance, so he shouldn't be able to stop the werewolf.
  • Also in the Goosebumps movie, Will is seen wearing Converse shoes, a possible reference to Tim Jacobus.
  • He isn't referred to by his real name in the film. R.L. Stine refers to Will as the title of his book, "The Werewolf of Fever Swamp".
  • The Werewolf was actually computer animated in the film, but they had stunt actor John Bernecker act out the Werewolves movement in a green suit.
  • The scene in the film where the werewolf scrapes his claws along the sides of the lorries could be a reference to Freddy Krueger.
