Although Supergirl debuted on CBS in the fall of 2015 to record-breaking viewership numbers for that particular season, the show experienced a decline in the ratings. After season 1 concluded earlier this spring, CBS made the decision to move Supergirl to The CW, where its second season will premiere this fall alongside new seasons of fellow DC Comics series Arrow, The Flash, and Legends of Tomorrow.

One aspect of season 1 that those behind the scenes of Supergirl hoped to fit into the story of Kara Danvers (Melissa Benoist) revealing her powers to the world - and, as a result, juggling superheroism with the difficulties of everyday life - was the introduction of Wonder Woman TV series star Lynda Carter as the President of the United States. Though it wasn't included in season 1, Carter has since confirmed to appear in season 2 as POTUS. Now, a new photo from the set of Supergirl gives us our first look at TV's Wonder Woman in the presidential role.

Benoist posted a photo to Instagram of herself on the set of Supergirl with Carter - though it's unclear whether Carter was in costume at the time the picture was taken. Benoist added the caption: "Met a wonderful woman today." Take a look at Supergirl and POTUS below:

Of course, Benoist's photo is only the latest in a series of teases from the various sets of The CW's superhero shows - all of which now film in Vancouver, Canada. Arrow star Stephen Amell, who is one of the most vocal cast members in terms of connecting with fans on social media, has shared photos that tease an Arrow season 5 flashback sequence as well as a team-up of heroes from all four series. Not to mention, Amell posted a photo of himself with new Supergirl cast member Tyler Hoechlin, who was fully suited up as Superman.

Certainly, between the images posted by members of the cast and photos taken from the set of Supergirl, we know some of what to expect from season 2. For instance, Supergirl will head to Clark Kent's home of Metropolis, DC Comics villain Metallo may appear, and fans will likely get to see Superman's classic transition from Daily Planet reporter to Kryptonian superhero at some point. Still, like Benoist's photo of herself with Carter, these hints from the set don't offer much in the way of concrete details.

That said, the season 2 synopsis for Supergirl revealed the series will continue exploring similar themes as season 1, specifically Kara's struggle between her job at CatCo and her work as the Girl of Steel. Additionally, with Supergirl set to premiere in less than a month and a half, it's likely The CW will soon release a trailer for season 2 - especially since Supergirl is the only one of the network's four DC Comics series that didn't debut a teaser at this summer's San Diego Comic-Con. However, if Carter has only now joined the Supergirl set, we may not see her version of POTUS in that trailer.
