Supergirl is about to gain one more Super Friend. Peta Sergeant (Snowfall) has joined the sixth and final season of Supergirl in a series regular role. Deadline was first to report the news.
Sergeant will play Nyxly, “a quirky and kind 5th Dimensional Imp.” She was wrongfully imprisoned in the Phantom Zone and holds a tragic backstory. This season will see her help and befriend Kara, and their friendship will provide emotional healing for Nyxly, as well as help her reclaim her powers.
Nyxly will be introduced in episode 4 of the season, titled “Lost Souls.” Viewers got a first look at Sergeant in the role in recently released photos from the episode, which you can find here. The episode will air on Tuesday, April 20 at 9 p.m. ET/8 p.m. CT on The CW.
