DC Comics and the Looney Tunes are two of Time Warner's licenses, so a crossover is possible. An idea that is unexpected to say the least, but which nevertheless seems to be coming to fruition.
Indeed, in a mysterious announcement that does not talk about the date or the series concerned by this crossover, DC has presented us with teaser images that unite Batman with Elmer Fudd by Lee Weeks, Jonah Hex and Yosemite Sam by Max Texeira, Martian Manhunter and Marvin the Martian by Aaaron Lopresti or Lobo and Coyote by Kelley Jones.
A project that seems very secret but that could boost the sales of DC Comics. In addition, the comic book universe and the Looney Tunes universe are not so far from each other. A mixture of these two worlds can therefore be quite saving, since Warner struggles to keep its DC Universe out of the water in view of some of its projects that seem compromised (cf: Batman).
