Season 3 images of 'Stargirl' show the Justice Society of America back in action ...

Sylvester Pemberton (played by Joel McHale), also known as Starman, is shown holding the Cosmic Staff for the first time. However, she later learned that Starman was not her father. A second picture shows Courtney and Sylvester talking to The Shade/Richard Swift (played by Jonathan Cake), a former member of the Injustice Society of America.

Courtney and Yolanda Montez (played by Yvette Monreal) converse with each other in Pat's garage, while another depicts Courtney in her Stargirl costume, along with Wildcat, Doctor Mid-Nite, and Hourman in their costumes.

Sylvester and his former sidekick Pat Dugan (played by Amy Smart) were photographed at Dugan's repair shop after Starman's death. Pat and Barbara then decided to relocate to Blue Valley to raise Courtney and her stepbrother Mike (played by Trae Romano).

One image shows Mike holding a pen that releases Thunderbolt, played by Alkoya Brunson, who is able to grant wishes. As these things go, the pen eventually found its way to Jakeem. Barbara Brooks, also known as Tigress, is also known as the villain Sportsmaster.

The third season of Stargirl, known as Stargirl: Frenemies, will premiere on The CW on August 31. In the meantime, check out the photos and the teaser for the upcoming season below:
