Just ahead of the Season 2 premiere, the CW has released the first official stills of Lynda Carter ("Wonder Woman") as President of the United States, Olivia Marsdin, on "Supergirl."

Set to make her debut in the third episode of the second season, titled "Welcome to Earth," the former "Wonder Woman" star will be recurring character throughout the season.

The official synopsis for "Welcome to Earth" reads:

LYNDA CARTER (“WONDER WOMAN”) LANDS IN NATIONAL CITY AS PRESIDENT OLIVIA MARSDIN — An attack is made on the President (guest star Lynda Carter) as hot-button, alien vs. human rights issues heat up in National City. Supergirl (Melissa Benoist) and the DEO are assigned to protect the President and bring in the responsible party. Alex (Chyler Leigh) teams up with Detective Maggie Sawyer (Floriana Lima) to investigate the case while Kara searches for a recently escaped Mon-El (Chris Wood), who she fears may be the alien behind the assault. Rachel Talalay directed the episode written by Jessica Queller and Derek Simon (#203). Original airdate 10/24/2016.
