Supergirl: Ranking Every Character From Worst To Best
19. Alura Zor-El
Kara's long-thought-to-be-dead mother, Alura Zor-El had a rather major role to play throughout the show's first three seasons, as the Girl of Steel's grief over her apparent death influenced a lot of her early adventures - all of which allowed her to realise that her mother may have been a little hasty with her treatment of Astra.
That said, it would turn out that the character hadn't died when Krypton exploded, as in Season 3, Kara stumbled upon Argo City (completely intact) only to discover her mother was alive after all - only this time, she was played by Smallville's Erica Durance instead of Laura Benanti.
While Alura's arc was explored more when she was considered dead than it was during her return, you can't quite ignore the importance of her character - and both Benanti and Durance brought different strengths to the role. Let's just hope that the show finds a way to bring Alura back in Season 5.
