Devil’s Due is scheduling a return trip for Hack/Slash and Mercy Sparx in December 2026. Hack/Slash Mercy Sparx: Canon Fodder #1, a one-shot written by Josh Blaylock with art by Jordi Perez, brings Cassie and Mercy back together for a case where a run of murders hits toxic fan communities and the apparent killers resemble characters pulled from the fiction their victims idolize.
The publisher has set the comic for December 9, 2026, at a listed price of $5.55. Ale Garza is credited for the cover. It is identified as the second Hack/Slash and Mercy Sparx crossover, so the premise is not positioned as a first encounter between its two central characters. The solicitation makes their friction a key part of the hook: Mercy and Cassie may not enjoy working together, but circumstances force them into the same investigation again.
What Canon Fodder #1 is setting up
A one-shot is a self-contained single comic issue rather than the opening chapter of an explicitly numbered miniseries or ongoing run. That label does not guarantee that every thread will be resolved within the issue, but it does tell readers that Canon Fodder #1 is being offered as one complete release. For readers who want the crossover without committing to a longer sequence, that is a meaningful practical distinction.
The story centers on an escalating murder wave within fan spaces. Its victims are said to be killed by figures that seem to have stepped out of the stories those communities celebrate. The setup deliberately plays with the boundary between fictional obsession and real danger, while keeping the plot rooted in a horror-mystery structure: someone, or something, is making the impossible pattern real.
Hank and Vlad get close enough to the truth to put themselves in jeopardy. That leaves Cassie and Mercy with the job of saving their friends while navigating their own strained partnership. The available description does not identify the murderer, explain the mechanism behind the fiction-fueled attacks, or say which fictional worlds the killers resemble. Those omissions are part of the mystery, not evidence of a particular supernatural explanation.
Blaylock is credited as writer and Perez as artist, a pairing shared by the crossover’s stated credits. Garza provides the cover, separating the interior-art role from the cover-art role for collectors and readers tracking individual contributors.
A crossover built around personality conflict
Crossovers can operate in several ways. Some exist mainly to place popular characters in the same frame; others use the meeting to test how incompatible approaches collide. The description of Canon Fodder #1 points toward the latter. Cassie and Mercy are not presented as seamless partners. Their irritation with one another is part of the premise, while the threat to Hank and Vlad supplies the immediate reason they must cooperate.
That tension could give the book two tracks at once: the investigation into murders linked to fandom and the challenge of getting the leads to work through their disagreements long enough to protect their allies. It also makes the issue approachable as a story with a clearly stated engine. Readers know the central crisis, the people placed at risk, and the uneasy alliance expected to confront it, even though the solicitation keeps the answer to the mystery under wraps.
The phrase “canon fodder” is an especially pointed title for this setup. In fan discussions, canon commonly refers to material regarded as official within a fictional continuity. The solicitation does not define how the title applies in-story, so it should not be treated as confirmation of continuity changes or a commentary on any one fan community. Still, alongside a plot about devotees and fiction-derived killers, it signals that the comic intends to engage with fandom language as part of its horror concept.
Club Nephilim #3 follows later in the month
December’s other listed release is Club Nephilim #3, due on December 23, 2026 for $5.55. Pat Shand writes the issue, Jordi Perez supplies the interior art, and Andrew Tarusov is credited for the cover.
Club Nephilim is described as exploring a darker and seedier area of the Mercy Sparx universe. In issue #3, Ladara and a supernatural group of allies discover that operating Club Nephilim is more complicated than they initially believed. The listing does not spell out the particular complication, the club’s full purpose, or whether the issue directly intersects with the events of Canon Fodder #1. Readers should therefore view the shared Mercy Sparx setting as the firm connection, rather than assume a required reading order from the December descriptions alone.
Perez’s involvement in both books makes the month notable for readers following that artist’s work across connected supernatural stories. The two releases otherwise have distinct creative leads and immediate narrative concerns: Blaylock’s crossover focuses on Cassie, Mercy, Hank, and Vlad amid a murder investigation, while Shand’s series installment follows Ladara and her team as the consequences of managing their club deepen.
Where these books fit for Devil’s Due
Devil’s Due Studios was founded in 2001 by Joshua Blaylock as a spin-off from Devil’s Due Comics. It operates as both a commercial art studio and small-press comic publisher. The company became particularly prominent in the early 2000s through licensed comics, especially its work involving G.I. Joe, and later shifted more of its attention toward original, creator-owned projects including Mercy Sparx and Club Nephilim while bringing back Hack/Slash.
That background makes a Hack/Slash and Mercy Sparx crossover a logical kind of release for the publisher’s current mix: it connects prominent supernatural-horror characters while the accompanying Club Nephilim issue expands a related corner of the Mercy Sparx setting. It is not, however, enough information to conclude that Devil’s Due is launching a broader linewide event. The December material identifies one one-shot crossover and one continuing issue; anything larger would need to be established by later announcements.
Comic readers looking across December’s broader publishing calendar may also want to compare how other horror-oriented collections are being presented; Heavy Metal’s December 2026 lineup, for example, is centered on restored covers and new story collections rather than this kind of character crossover.
