Despite see-sawing ratings and some comic book readers’ general apathy towards the show, Supergirl has always tried its best to make a difference in the world of genre television.ĭebuting in 2015, the show starred Melissa Benoist as Kara Danvers/Supergirl, Chyler Leigh as Kara’s sister and second-in-command of the Department of Extranormal Operations Alex Danvers, and David Harewood as DEO Director Hank Henshaw, who later revealed himself to be J'onn J'onnz/Martian Manhunter. The Girl of Steel took her final flight with Supergirl season 6, but she’s left an indelible mark on the CWVerse.
