One of the last major times that the DC and Marvel Universes collided was in the 1996 crossover event Marvel vs. DC that saw the two publishers' iconic characters come to blows.Written by Ron Marz and Peter David and illustrated by Dan Jurgens and Claudio Castellini, readers voted on the outcomes of five of the miniseries' marquee fights, with the rest determined by the creative team. One such fan-voted match-up was between Superman and the Hulk and, while the Man of Steel triumphed the final showdown, Marvel Comics Executive Editor Tom Brevoort has shared the unused piece of artwork by Castellini had the Green Goliath emerged victorious.
Following positive response from the initial post, Brevoort posted the artwork that would ultimately be colored and published in the actual crossover as the Man of Tomorrow laid out the Jade Giant with a single mighty punch.
With major comic books from the two publishers ceasing distribution in the face of the ongoing coronavirus (COVID-19) pandemic, comic book creators have joined forces to suggest a hypothetical new crossover between the two universes.
The last major intercompany crossover between the two superhero universes occurred in 2004's JLA/Avengers by Kurt Busiek and George Perez. Since then, both companies have largely stuck to their own, self-contained universes, occasionally teaming up with smaller publishers for subsequent crossovers.
