Peta Sergeant Joins Season 6 of “Supergirl”

According to, Peta Sergeant has joined the cast of “Supergirl” as a series regular for the remainder of the show’s sixth and final season.

Sergeant will play Nyxly, a quirky and kind 5th Dimensional Imp, wrongly imprisoned in the Phantom Zone and driven by tragic backstory. She helps Kara when she least expects it, and their budding friendship not only heals some of Nyxly’s emotional pain, but helps Nyxly reclaim her own power.

This comes on the back of the recent news that Thomas Lennon is returning to play the role of Mxyzptlk.
