The crossover craziness between Marvel and DC isn’t just limited to the comic book page, with the two companies announcing the surprise digital drop of two additional crossovers — Flash/Fantastic Four, and Thor/Shazam! — immediately available on the companies’ digital subscription services.

Both DC and Marvel are releasing one crossover each on their subscription service, with Flash/Fantastic Four by Jeremy Adams, Adrián Gutiérrez and Romulo Fajardo Jr. appearing in the DC Go! section of DC Universe Infinite, while Thor/Shazam! by Al Ewing and Jethro Morales is an Infinity Comic available in Marvel Unlimited.

DC’s description of Flash/Fantastic Four runs as follows: “In The Flash/Fantastic Four, available now, exclusively from DC on DC UNIVERSE INFINITE, Barry Allen and the Fantastic Four tear through the Speed Force, encountering heroes and villains across time in a bid to stop Gorilla Grodd’s quest for mental domination. Written by Jeremy Adams, with art by Adrián Gutiérrez and colors by Romulo Fajardo Jr., this DC GO! webcomic is a high-speed, high-stakes DC/Marvel crossover adventure.”

Marvel’s description of Thor/Shazam! is, per the publisher, “The might of Thor! The power of Shazam! Marvel and DC bring the thunder to Infinity Comics in a never-before-seen adventure! When a familiar face threatens to usurp the magic of the Marvel and DC universes, will Donald Blake and Billy Batson recover their powers in time to stop them?”

It’s not only the characters that are crossing over; to accompany the launch of the digital crossovers, both Marvel and DC are offering subscribers of their digital platforms a 30-day free trial to each others’ service, as long as they are signed up before December 15 2025.
