Cassandra "Cassie" Hack is a fictional character that appears in the Hack/Slash comic books published by Devil's Due Publishing.
The character first appears in Hack/Slash: Euthanized (April 2004), and was created by writer and occasional penciller Tim Seeley.
Seeley has repeatedly stated that Cassie is designed to be a horror victim who has overcome her fears and decided to take revenge on horror villains, who are known in the comic as "slashers".
However, despite her hardened exterior, Seeley has tried to show that "beneath [the surface Cassie] is still lost, scared innocent girl".
