Popverse's coverage of Comic-Con International: San Diego 2026 is brought to you by Dark Horse Comics.

DC Comics has spent years trying to get James Tynion IV to do more superhero work. The comic company is finally getting their wish, even if Tynion’s first choice gave them pause. Swamp Thing is Killing the Children is an upcoming crossover between Swamp Thing and Tynion’s Boom! Studios horror series Something is Killing the Children. For Tynion, the title was too good to pass up. 

“It did start with the title Swamp Thing is Killing the Children,” James Tynion IV says during a panel at San Diego Comic Con. “That was something that I remember talking about with [DC editor-in-chief] Marie Javins when I was still on the main Batman book. Something is Killing the Children was a rising success, and we were going to lean in. Let’s do a crossover. And Marie was like, ‘I don’t know about that, James.”’

Tynion was the writer on Batman in 2020 and 2021, and the Swamp Thing is Killing the Children isn't coming out until this fall.... so that means this has been in the works for at least six years.

“It took a few years, and they’ve been knocking on my door asking me to do more superhero stuff, and I was like, ‘There’s one story I would be very happy to tell with DC characters, if you would just let me.’ And finally the door opened to do it, and I think Jim Lee had to explain to Warner corporate that this was still going to be a story respectful of Swamp Thing, despite the title.”

As of this writing Swamp Thing is Killing the Children doesn’t have a release date, but it’s expected to hit the shelves sometime in Q4 2026.
