Supergirl has flourished in its second season, and has become one of the best superhero shows on TV since it moved from CBS to The CW. The show follows the exploits of Kara Danvers, a mild-mannered reporter for CatCo News in National City, who also happens to be the city’s most famous superhero, Supergirl.

Supergirl Season 2 has begun to explore Supergirl’s Kryptonian roots, and has not shied away from the source material; for instance, Season 2 saw the debut of her more famous cousin, Superman. Kara has begun to deal with what it means to be a hero, and how it affects all facets of her life.

The big bad in Supergirl Season 2 is the anti-alien organization Cadmus, headed by the evil Lillian Luthor. The shadowy organization is intent on wiping aliens off the face of the Earth, but Supergirl and the D.E.O. will do anything in their power to stop them.

Latest 'Supergirl' Season 2 Trailer

The trailer for Supergirl Season 2 Episode 18, titled “Ace Reporter”, promises a triumphant return for the Girl of Steel, and the arrival of some new villains to National City. Check out the official synopsis below:

"Lena's ex-boyfriend, Jack Spheer, comes to National City to unveil his big breakthrough in nano-technology, which has the potential to eradicate all diseases. Lena asks Kara to attend Jack's conference with her for support. When Kara sees Snapper in attendance she's inspired to tap back into her reporter skills and questions Jack on his discovery, which ultimately leads to a bigger investigation that puts everyone in danger."

This trailer shows glimpses of Lena Luthor (Katie McGrath), who is an ally to Kara, but her family ties mean her overall loyalties remain nebulous. We see Queen Rhea of Daxam (Terri Hatcher), who has recently vowed to defeat Supergirl at all costs, and seems to be plotting to take out the girl who "stole" her son, Mon-El. Although the new villains are unknown, it seems like Lena Luthor's ex-boyfriend will serve as the antagonist for the episode.

'Supergirl' Season 2 Theories

Unlike other Arrowverse shows, Supergirl has shied away from big villain mysteries, and has focused on a more character-driven plot for Season 2. While there have been some mysteries – like Mon-El’s true lineage – all of them have been answered this season.

There is fan speculation about Lena Luthor’s intentions, and that she might be playing Kara for a fool — but those theories have yet to hold any ground. It would not be surprising if the sister of Lex Luthor turned out to be evil; however, at this point, she is simply trying to take back the Luthor name, and make it a force for good.

Supergirl is also rumored to be bringing in the Legion of Superheroes, as they have dropped many hints about their arrival this season.

Where To Watch 'Supergirl' Season 2
