All hail the chief!

The CW announced on Tuesday that Lynda Carter is joining Supergirl's second season as the President of the United States. Carter is, of course, most known for her iconic portrayal of Wonder Woman on the original 1970s television series. She will be a recurring character in the second season after making her first appearance in episode 3.

Earlier this year, executive producers Andrew Kreisberg and Greg Berlanti told TVGuide.com that they had approached Carter for the role earlier but scheduling made it impossible to include her in the first season.

"We're going to do it, we'll just do it next year," Kreisberg said. The Season 1 finale also hinted at Carter's turn when the president sent "her" thanks to Supergirl for saving the planet.

Carter is just the latest in a slew of casting additions to Supergirl's sophomore effort. The show is also adding Teen Wolf alum Tyler Hoechlin as Superman. Carter adds another powerful female actress into the frame though while it still remains to be seen how large of a part Calista Flockhart's Cat Grant will play in the new season. The CW and Warner Brothers had no comment on whether Flockhart would remain a series regular transition to a recurring character when TVGuide.com reached out earlier this month.

Supergirl premieres Monday, Oct. 10 at 8/7c on The CW.
