Will Blake is a terrifying and aggressive werewolf. He is a massive, bipedal lycanthrope with thick brown fur, orange eyes, and a muscular build. His primary instinct is to hunt, and he proves to be a relentless foe. He is one of the many monsters released from R.L. Stine's manuscripts by Slappy the Dummy. He pursues the main characters, Zach, Hannah, and Champ, causing chaos and destruction in a grocery store and later joining the other monsters in their siege of the high school.
