As surprise announced at last year’s New York Comic Con, Something is Killing the Children is crossing over with DC’s Swamp Thing, in the first ever crossover for BOOM! Studios‘s Slaughterverse. And we’ve finally got the covers to prove it’s all actually happening.
Hitting stores in December, the 64-page one-shot will be by James Tynion IV and Werther Dell’Edera, aka the team from SiKTC. And the meta-premise finds two siblings who are fans of horror comics discovering the characters on the pages are coming to life, and it’s up to Erica Slaughter to hunt them down… Including Swampie.
You can check out the full synopsis, solicit info, and covers below, via PR from BOOM! And speculate wildly about what the next punny crossover could be. Smurfs Are Smurfing The Smurfs, perhaps?
In a world where the fears of children manifest into living, breathing monsters, this crossover brings one of horror’s most iconic characters straight into the Slaughterverse!
James Tynion IV and Werther Dell’Edera, the superstar team behind the smash hit Something is Killing the Children, push the boundaries for the very first crossover story ever told in the fan-favorite Slaughterverse.
Two siblings who are life-long comics fans find their way to horror comics, in spite of the fears they inspire.
As the terrifying visions from the pages of the comics start to come to life, Erica Slaughter will have to hunt down one of horror’s most recognizable figures—Swamp Thing himself!
