Season four of Supergirl is off to a great start and there's still much more to come, including the introduction of several DC Comics characters who have yet to make their live-action debuts.
Among them is Ben Lockwood, a character better known to comic book fans as Agent Liberty. It's thought that he'll suit up somewhere down the line but this episode - titled "Man of Steel" - is going to put the spotlight on his origin story (which is set to include a guest appearance from The Walking Dead alum Xander Berkeley as the character's father).
For more on what to expect from this episode, here's the officially released description from The CW:
XANDER BERKELEY GUEST STARS IN THE ORIGIN STORY OF AGENT LIBERTY — Ben Lockwood (Sam Witwer) didn’t always hate aliens. Through a series of incidents, and input from his anti-alien father (guest star Xander Berkeley), Ben slowly transforms from a mild-mannered professor into the villainous Agent Liberty of today. Jesse Warn directed the episode written by Rob Wright & Derek Simon (#403). Original airdate 10/28/2018
