The CW’s Supergirl welcomes Peta Sergeant as a series regular for Its sixth and final season. The sergeant will be joining Melissa Benoist in the titular role, along with David Harewood, Chyler Leigh, Katie McGrath, Nicole Maines and Jesse Rath. The Super Friends continue their struggle with Lex Luthor (portrayed by Jon Cryer) which is placed at risk if Lex sends Kara to the Phantom Zone at the end of the season’s premiere.
That is exactly where we meet Sergeant’s personality, as she plays “a unique and type 5th Dimensional Imp” named Nyxly. Nyxly has been wrongly imprisoned in the Phantom Zone and builds a formative friendship with Kara that helps her cope with her psychological trauma together with rebuilding her strength. No further details about Nyxly’s personality or backstory have been shared and it’s uncertain which episode she will first appear in. Sergeant isn’t the only brand new cast member to joining the Supergirl team. Rosewell’s Jason Behr and Supernatural’s Claude Knowlton will even carry on recurring roles for the final season, the identities of whom have never been announced.
It’ll be interesting to see Kara’s connection with Nyxly and how it may differ to this with everybody’s favourite 5th Dimensional Imp, Mxyptlk (depicted by Thomas Lennon), that will also be returning for the final season. His and Kara’s friendship has been atypical, but he’s always played the part of a manual (when he is not overly lovesick for Supergirl himself ), so it’ll be a different dynamic to watch as Kara attempts to cure the woes of an almighty 5th Dimensional being.
