Let's face it. When the Gunnverse gets to its justice league. it's gonna be way better established than the Synderverse.

Superman, Batman and Wonder woman all have solo films.

Green Lantern has an HBO miniseries.

Teen Titans is likely gonna have Wally in it's lineup. Flash will need to be addressed either way.

Hawkgirl, Mr. Terrific and Metamorpho are waiting in the wings as well.
