A little over a month until Supergirl returns for season 4 on a new day.
Supergirl is based on the DC character Kara Zor-El, Superman’s cousin, who after 12 years of keeping her powers a secret on Earth, decides to finally embrace her superhuman abilities and be the hero she was always meant to be.
This season anti-alien sentiment reaches new heights in National City and we see new enemies such as iconic DC villain Mercy Graves (played by Rhona Mitra) as well as Sam Witwer (Being Human) as anti-alien hatemonger Agent Liberty.
Check out the trailer below.
Supergirl returns on Oct. 14 at 8/7c on its new day.
