Earlier this month, Warner Bros. saw Wonder Woman march into theaters for her first live-action standalone, and the heroine has been breaking records since. The newest DCEU film has garnered rave reviews from both fans and critics, leaving many to wonder whether Warner Bros. will push DC Entertainment to introduce more female superheroes to its franchise. And, now, one rumor is suggesting the DCEU may be eyeing Supergirl for such an occasion.

The DCEU fandom has been given a new rumor to consider thanks to an anonymous source from 4chan (via ScreenRant). The post claims that Man of Steel 2 is in development already and will act as a premiere platform for Supergirl.

“The sequel to Man of Steel has been developing in secret,” the post writes. “Geoff Johns and Zack Snyder finished writing a story for the film back in November. Multiple writers were approached to turn into a screenplay including the writers from Watchmen and the 300 movie series. Brainiac will be the villain and Supergirl will be introduced to the DCEU.”

Of course, there is no evidence to back up the sources claim. Warner Bros. will likely leave the rumor to simmer in it own ambiguous state should they catch wind of it, but the notion does give fans plenty to ponder. Supergirl has become a more lucrative heroine to DC Entertainment as of late thanks to the character’s titular show. The CW wrapped the second season of Supergirl recently, and a third season has already been ordered.

Still, there is a chance that bringing in Supergirl to the DCEU may cause a rift with fans. DCEU diehards will surely remember the controversy which arose when Ezra Miller was cast as the Flash for Justice League. Fans of the Arrowverse on The CW pushed back against the casting as they associated Grant Gustin with Barry Allen thanks to the network’s standalone series. Melissa Benoist is the actress currently tied to Supergirl, so the franchise will surely face resistance once more should they be wanting to cast the heroine into the DCEU.

When it comes to Man of Steel 2, much remains a mystery to fans. Audiences only know the film is in the works as Henry Cavill’s reps have nodded to the sequel in regards to the actor’s schedule. There is no anticipated release date for the new film, but DC Entertainment has some time to nail down the particulars. Justice League still has its premiere coming later this year, and other projects like Aquaman are now filming. With plenty of features in active development or production, Man of Steel 2 will have to wait its turn for the spotlight. And, when the film does get its start, fans may just get to see Superman’s cousin make a brief appearance.

Justice League currently has a 4.16 out of 5 on ComicBook.com's anticipation rankings, and the official description can be found below.

In Justice League, fueled by his restored faith in humanity and inspired by Superman’s selfless act, Bruce Wayne enlists the help of his newfound ally, Diana Prince, to face an even greater enemy. Together, Batman and Wonder Woman work quickly to find and recruit a team of metahumans to stand against this newly awakened threat. But despite the formation of this unprecedented league of heroes—Batman, Wonder Woman, Aquaman, Cyborg and The Flash—it may already be too late to save the planet from an assault of catastrophic proportions.

Justice League is directed by Zack Snyder, from a screenplay by Chris Terrio, and features an ensemble cast that includes Ben Affleck (Batman), Henry Cavill(Superman), Gal Gadot (Wonder Woman), Ezra Miller (The Flash), Jason Momoa (Aquaman), Ray Fisher (Cyborg), Ciarán Hinds (Steppenwolf), Amy Adams (Lois Lane), Diane Lane (Martha Kent), Jeremy Irons (Alfred Pennyworth), J.K. Simmons (Commissioner Gordon), Amber Heard (Mera), Kiersey Clemons (Iris West) and Jesse Eisenberg (Lex Luthor).
