Everyone has heard and probably watched and read about Superman. But, what about Supergirl? Doesn’t ring a bell? Well, Supergirl is a popular American superhero television series that is based on the DC comics, Supergirl. The show is created by Ali Adler, Greg Berlanti, and Andrew Kreisberg and initially aired on CBS.

If you aren’t much of a comic person and have no idea about Supergirl, she is Superman’s cousin and one of the few last surviving Kryptonians. This show is the third installation in the Arrowverse and brings the audience an extension of the amazing world of DC comics.

The first season of the series initially aired on CBS in 2015 and the last and the sixth season of the series aired in March 2021. The show gained a range of great reviews from the audience and critics throughout the release, reeling in more and more viewers with each season.

What is the plot of Supergirl?

Expanding across six seasons, it is often hard to decipher in works every single development of the show, however, we have tried to narrate the premise of the show with hopes that you get an idea of what you can expect from each season.

The plot of the series follows the life of Kara Zor-El who was sent to Earth as a 13-year old by her parents Zor-El and Alura. However, things take a tumble soon. Kara, who was sent to Earth to protect her cousin, Kal-El as an infant, gets stuck in the Phantome Zone for 24 years before her spacecraft crash lands on Earth.

However, once she reaches Earth, she realizes that her infant cousin is a grown-up and has become Superman. Fast forward 11 years from then, Kara tries to embrace her superhero powers and tries to take on the alias of Supergirl.

The first season of the show follows Kara’s life as a National City’s protector. She soon realizes that several of the criminals that are mother captured are now hiding away on Earth, including her aunt and uncle. Kara soon takes help from her adoptive sister, Alex Denvers, the two of them joining hands to take down the evil in the world.

Moving to the second season, it starts with Kara and her friends getting in between feuds between the extraterrestrial community and the natives on Earth. While trying to overcome the evil and make new connections, Kara meets the new Earth arrival, Mon-El, and can’t help but start developing feelings for him.

The third season of the show takes the audience through Kara’s struggles with Mon-El, especially when he is forced to leave the planet. However, he soon returns to Earth and meets Kara, where he discloses that he had time travelled to the 31st century and found the Legion. He also reveals that he married Imra Ardeen in the process. With so many things happening, Kara and Alex’s friend, Samantha discovers that even she is a Kryptonian survivor. 

The fourth season of the show is where all hell breaks loose. Kara deals with a range of anti-extraterrestrial invasions that had been instigated by Lex from prison. Things happen in their natural discourse and Kara and Alex find themselves in class with DEO’s new addition and decide to keep an eye out on them.

The fifth season of Supergirl is overpowered by the presence of a new threat, Leviathan, who sends their agent Rama Khan, an immortal, to kill Kara. Following the discovery, Kara adjusts to her new life at Earth prime while working for Lex and Leviathan.

The last and final season is where Lex attempts to finish what he started. In the process of conquering the multiverse, he imprisons Kara in the Phantom Zone. However, Kara’s allies come to her rescue and get her out of there.
