26. Maxwell Lord, cameos in Superman, and is the sponsor for the Justice Gang, appears to be holding the Firestorm Matrix in the mural

In a new interview with IGN, James Gunn has teased that at the very least, 2 out of the 26 heroes in the mural are important to an upcoming DCU project.

"Listen, fans have done a pretty good job, I think they've found all of the different characters," said Gunn on the mural. "But yeah, I will just say that in one of our scripts we're working on two of those characters are kind of important."

It's worth noting that Gunn said two of these characters are set to appear in the same upcoming project. Whether that's a film, TV show, or animated series is anyone's guess.

Exoristos could be important to the Paradise Lost TV show as she's an ancient  Amazon who predates Wonder Woman. 

Max Mercury is featured twice on the mural and is incredibly important to Speed Force lore in DC Comics history.

Sean Gunn's Maxwell Lord is another obvious choice as the character already appeared in Superman.

Gunn teased that he wouldn’t be dropping any hints, leaving it up to fans to speculate about which two heroes he was referring to and what mysterious project they might appear in.
