The story everyone has been waiting for is finally here! Dynamite Entertainment and Warner Bros. Discovery Global Consumer Products have announced a historic comics crossover event 40 years in the making. ThunderCats X SilverHawks kicks off this April with a trio of interconnected comic book titles telling a thrilling 15-part epic story from top creators as the pinnacle of over two years of revitalized storytelling. Civilizations collide in the crossover of the millennium, as writers Declan Shalvey and Ed Brisson pick up the pieces and ramp up threads from nearly 60 issues of new tales across the ThunderCats and SilverHawks mythos, cresting to a can’t-miss climactic crossover for dedicated diehards, and an approachable starting-point thrill ride for those intrigued by this blockbuster.

Critically acclaimed author and illustrator Declan Shalvey kicked off this whole era with the records-setting ThunderCats #1, and here he continues his signature contributions to the saga by not only writing, but also drawing the first issue of the flagship series starting in ThunderCats X SilverHawks #1. This follows the conclusion of the milestone ThunderCats #25 and the setup special ThunderCats X SilverHawks: Road to War. Extra-sized with 30 story pages, the kickoff chapter starts it all with a bang.

Panthro of the ThunderCats’ mission to launch a new satellite high above his adoptive home of Third Earth resulted in an unexpected turn of events that will change the destiny of two entire galaxies. Alerted to an anomaly at a long-dormant base in a quarantined sector, The Copper Kid, Quicksilver, and Chromium of the SilverHawks set out to investigate. As soon as they land on the forbidden planet, they’re confronted by a fearsome band of strange, cat-like warriors — and quickly find themselves in a fight for their lives!

The second series and part two starts with ThunderCats X SilverHawks: Mumm-Ra the Ever-Living #1. Shalvey also scripts this look at the archnemesis of the entire franchise, alongside artist Rapha Lobosco. Mumm-Ra has been a sinister enigma to the ‘Cats ever since they first set their paws on Third Earth, and now the full ancient and tortured history of the infamous devil-priest will be revealed! While interweaving with the ever-evolving 15-part epic, this series dually functions as an essential origin for fans.

Following his fan-favorite chronicles of the SilverHawks, the ThunderCats Lost team, and a string of scintillating specials, writer Ed Brisson writes the third title involved in the crossover, joined by artist Vincenzo Federici. ThunderCats X SilverHawks: ThunderHawks #1 follows events from ThunderCats: Lost in Time and the Road to War special, starting with the Lost team trapped in the far future desperately trying to get back home and prevent the cataclysmic war that could end all of ‘Cat-kind. They’ll find themselves donning SilverHawks bionic suits and fighting in this unknown, hostile space and time.

Each month from April through August 2026 will feature a new chapter from all three titles, continuing to build and complement each other to form the ultimate ThunderCats and SilverHawks legend and celebration of these fabled franchises.
