Former "Wonder Woman" star Lynda Carter makes her first appearance on "Supergirl" Monday and TODAY has a sneak peek!

Carter, who played the Amazonian superhero for three seasons on the classic '70s TV show, joined the cast of "Supergirl" for its second season.

We apologize, this video has expired.

This time around, Carter, 65, trades her invisible jet for Air Force One. That's right, the still-stunning actress portrays impossibly chic U.S. president Olivia Mardsin.

Monday night's episode, which deals with intergalactic drama, finds Madam President attacked by outer space aliens. But, have no fear, Supergirl (Melissa Benoist) saves the day!

Don't go thinking Carter has hung up her own superhero cape just yet. The actress visited TODAY Thursday morning, where she paid a surprise visit to a super fan named Jo Ann Jantz Tolbert.

The visit, arranged by TODAY's Hoda Kotb, found Carter sharing an emotional hug with Tolbert, who's been courageously battling Stage 4 breast cancer.

Carter thrilled the mom of two from upstate New York when she gave her an autographed painting from her "Wonder Woman" days.

"Being little girls in the '80s, we had our Wonder Woman Underoos,'' Tolbert's close friend, Jessica Fong, told TODAY. "And she's been a fan of Wonder Woman since it was on TV. It's kind of become her champion, her icon for her battle."

Sounds like Carter and Tolbert are both heroes.

"Supergirl" airs Monday at 8 p.m. on The CW.
