Supergirl was the third series to join the Arrowverse, but started on CBS before moving to The CW in its second season. It debuted on October 26, 2015.

Kara Zor-El was sent to Earth to help raise her cousin Kal-El. Although they left Krypton at the same time, Kara’s ship was sucked into the Phantom Zone and didn’t arrive on Earth until after Kal-El had grown into an adult.

Kara eventually takes on the human name of Kara Danvers, and eventually becomes Supergirl (Melissa Benoist). With the help of her sister Alex (Chyler Leigh), her friend James Olsen (Mechad Brooks) and more, she now helps to save the world from various threats.
