Warner Bros. certainly has a lot waiting down the pipeline, especially with so many project announcements in the past few months. This includes a prequel series to James Gunn's The Suicide Squad starring John Cena as Peacemaker and the previously rumored Green Lantern live-action series, both of which will premiere on HBO Max.
The studio is even planning on having even more series that won't be related to the DECU at all, such as a spin-off series based in the universe of Matt Reeve's The Batman. Warner Bros. could also use its streaming service to introduce entirely new characters to a wider audience, even characters that have already been adapted into live-action on the CW.
According to GWW, which was told by multiple independent sources, Warner Bros. plans to develop a Vixen project. GWW's headline of their report indicates that this project will be set in the DC Extended Universe.
WHAT THIS MEANS
As GWW speculates, this could very easily be a property for HBO Max, which wouldn't be surprising considering the amount of DC content Warner Bros. has planned for the service. More interestingly, GWW points out that Vixen would be joining the DCEU and not that it would be its own pocket universe like Matt Reeve's The Batman.
This could mean that the Vixen project could eventually connect to other properties like Wonder Woman 1984 or Black Adam, considering that Mari McCabe, Vixen, has her powers due to an artifact, the Tantu Totem, being passed down in her family for centuries. It would be fun to see Tantu asking the god Anansi to create the totem in Black Adam in ancient Africa.
Additionally, depending on the pitch, the project could still end up being its own movie focused on the character, which would be equally as exciting since it would be the first superhero since Catwoman to star a black woman.
