Kara will face Superman villains Lumberjack in the pilot episode and the infamous DC villain Reactron in episode 3 CBS

CBS's new series Supergirl will premiere on 26 October and will follow the adventures of Superman's cousin, Kara Zor-El.

According to a new report, Kara will face Superman villains Lumberjack in the pilot episode and the infamous DC villain Reactron in episode 3.

TVLine reports that Melissa Benoist's character Kara Danvers/Zor-El will have her work cut out from the very beginning, as her adversary in the series pilot episode will be the DC Comics villain Lumberjack, who earlier fought Kara's cousin Superman.

CBS is seeking a hulk akin to Rory McCann, the 6.6 feet actor from Game of Thrones to play to the "big, burly monster of a man, who has battled Superman in the past".

Meanwhile, DC Comics' villain Reactron is also poised to take aim at Kara in episode 3. The nuclear-powered, exoskeletal chest-plated madman has a long-held grudge against Superman.

In the Superman: New Krypton comic, Reactron is responsible for the death of Kara's parents.

Here is what we know of the CBS show so far:

1. Lucy Lane will be introduced: The third episode of the CBS series will introduce the recurring character of Lucy Lane. She is described to be in her mid-20s or early 30, brash, funny and beautiful as her sister Lois, yet strong, smart and successful in her own right.

She will also keep with the DC Comics lore, and will be an ex-girlfriend of Kara's new colleague and Daily News transplant Jimmy Olsen (played by Mehcad Brooks) a TVLine report said.

2. Synopsis out: The official synopsis of the show reads: "This one-hour drama is an epic action-adventure for the entire family. Combining the heart, humor and spectacle of a super hero series, with the week-to-week intrigue of the DEO's investigations, Kara's childhood memories of her time on Krypton and the sophisticated workplace dramedy of her secret identity at Catco, Supergirl is charged with true epic storytelling—bringing a strong female hero to television screens at long last."

3. Will Superman guest star: Executive producer Ali Adler had earlier teased Superman's involvement in the show. "Our prototype is the way the president is seen on Veep. It's certainly [inspired by] so much of what Julia-Louis Dreyfus' character goes through. Ultimately, this is a show about Supergirl and we really want to see it through her lens."

4. Expect a lot of flashback: The executive producer further stressed that fans will learn more about a young Kara Zor-El in flashbacks.

Alder told Entertainment Weekly: "We'll absolutely see some flashbacks of her discovering them, because she was 12 years old when she landed here, and she didn't have these powers on Krypton. Kal-El came here as an infant."

"He didn't know himself on Krypton. Kara hasn't used these powers very much or very well, certainly not to the extent that she's going to be a hero as she started in the pilot. There will definitely be a learning curve at the beginning of the season," he added.
