Brent Spiner will be joining the cast of The CW's 'Supergirl' for its fourth season. Spiner ā€” best known for his portrayal of android Lieutenant Commander Data in TV series 'Star Trek: The Next Generation,' as well as four subsequent spinoff films -- Star Trek Generations, First Contact, Insurrection, and Nemesis ā€” will feature in the superhero action-adventure as President Olivia Marsdin'sĀ (Lynda Carter) right-hand man.

According to TV Guide, Spiner has been cast in the role of Vice President Baker. Described as "adept and politically-minded," Bake is an unlikely leader who will "step up in a big way when his country needs him the most."

Season 4 will see Sam Witwer's (Battlestar Galactica, Smallville) Agent Liberty take on a prominent role, waging an all-out war against the aliens protecting the planet including, of course, our favorite Supergirl (Melissa Benoist).

Carter's President Marsdin first made her bow in the series in season 2 episode titled 'Welcome to Earth' and is yet to reveal her identity as an alien to the country. Understandably, it will be high on her priorities to see Agent Liberty and his alien hate group, The Children of Liberty, taken down swiftly.

Besides Spiner, Season 4 will also be special because of Nicole Maines' casting. The 'The Trans List' actress is all set to become television's first-ever transgender hero with her portrayal of Nia Nal/Dreamer. Dreamer has been described as "a soulful young transgender woman with a fierce drive to protect others," with season 4 chronicling Maines' evolution into the superhero; her transformation has been likened to that of how Melissa Benoist's Kara Danvers/Kara Zor-El came into her own as Supergirl.

In addition to Maines, fans of the show will also be seeing the addition of two more cast members. April Parker Jones (Jericho, The Last Ship) will feature in the series regular role of Colonel Haley, "a hardline career military woman who lives and dies by the orders of her commanding officers." Dedicated to her country, she will always act in its best interest ā€” even if it's not her own.

David Ajala (Dr. Who, Nightflyers, The Dark Knight) will portray the recurring role of Manchester Black. An official description for the character reads: "Based on the iconic DC character, Manchester Black is the type of guy who brings a knife to a gunfight and still walks away the winner. With a dark past, he easily deflects the brutality of his mission with his charm and sense of humor."

Jesse Rath was promoted to series regular for season four after previously recurring as Querl "Brainy" Dox/Brainiac 5. Jeremy Jordan, an original cast member as Winslow 'Winn' Schott Jr., will move in the opposite direction and appear in a recurring role.
