"Supergirl" is television's newest superhero and it's clear this series is going to be a fun and exciting one.

According to Deadline, "Supergirl" is tied with "Blindspot" as the top-rated new show this season, and, no doubt, "Supergirl's" compelling storyline played a part in its success.

The plot began when 13-year-old Kara Zor-El was sent to Earth to protect her cousin Kar-El or Superman. Her vehicle got stuck in the Phantom Zone for years before mysteriously breaking free and landing on Earth. With the help of her now-famous cousin, she ended up getting adopted by the Danvers and left to create her own life.

Years later, Kara Danvers worked as an assistant for media mogul Cat Grant. An early love triangle presented itself with Winn Schott, who's infatuated with Kara, and James Olsen, Superman's photojournalist pal and new art director of The Tribune.

After being ditched by a blind date, Kara heard of her sister's airplane experiencing engine failure above the city. To save Alex, Kara flew after the plane and prevented the crash. but it came at a price: her anonymity.

As Kara embraced her superhero status, she got captured the Department of Extranormal Operations, which Alex was a part of. Director Hank Henshaw told her that Krypton's maximum security prison Fort Rozz crashed into Earth with her, releasing galaxy's most dangerous criminals.

Kara got her first unsuccessful taste of fighting against Vortox, who wanted revenge after Kara's mother put him in prison. Alex and the DOE saved her but was left in low spirits at her defeat. Her sister gave her a message from her mother, who inspired Kara to keep making a difference as Supergirl.

In her second fight against Vortox, Kara defeated the alien, who said that there are bigger threats out there. Later, Olsen revealed he knew her identity all along as he was sent to National City by Superman.

Wrapping up the episode was the twist that revealed who was behind the movement against Kara: her mother's twin, Astra.

"Supergirl" executive producer Andrew Kreisberg talked more about the villain in an interview with Entertainment Weekly.

Kreisberg said, "It's always great when the hero and the villain are two sides of the same coin. Astra's version of saving the Earth is quite different from Kara's."

He added that not all the Fort Rozz escapees are evil, saying, "They're not all mustache twirling, revenge seeking, we-want-to-rule-the-world creatures. They've got lives, loves, desires, dreams, fears and hopes just like anybody. Watching how Supergirl deals with them, sometimes in heartbreaking ways, is what makes every episode different. It's what helps Kara on her journey to becoming the hero that she can be."
