Supergirl: Season 4

The thrilling fourth season of Supergirl is a must-watch for superhero fans. After a short hiatus following the show's third season, the Caped Crusader of National City has returned, ready to save the day and prove once and for all that she's the best at what she does, which is saving the world from existential threats and dealing with a volatile meta population.

The season opener, "Star-Crossed," sees Kara and Alex dealing with a new generation of conquerors, while Mon-El has to adjust to living on Earth. Meanwhile, Reign returns, only to reveal that she's much more than a villain; she's a sister to Nia Nal, and together they'll put Kara, Alex, and the rest of National City to the test.

Fans will also see the return of Morgan Edge, the brilliant and treacherous CEO of Apokolips, who could be the most dangerous threat Supergirl and the rest of the DEO have ever faced. As the season progresses, Supergirl will face off against Mon-El's mom, Astra, while also exploring Kara's history with her cousin and proving to her that she's worthy to carry her legacy.

The team dynamics change, and relationships are tested in this season, although ultimately everyone learns to stand together, facing challenges head-on with courage, compassion, and care, just like Supergirl.
