Hack/Slash Mercy Sparx

In 2010, Devil's Due Publishing brought together two fan-favorite horror-comedy heroines in a single-issue crossover: Cassie Hack of Hack/Slash and Mercy Sparx from her own series. Written by Tim Seeley, this one-shot pits the slasher-hunting Cassie against a supernatural threat alongside the demon-fighting Mercy, blending their distinct brands of wisecracking, monster-bashing action. Though brief, the issue serves as a fun, self-contained team-up that highlights the shared universe potential of Devil's Due's creator-owned horror line.
