The CW has released the official synopsis for "The Adventures of Supergirl," the season two premiere of Supergirl, which will air on Monday, October 10 on the network.

As more or less everybody knows at this point, Supergirl's famous cousin will be coming to the series in the form of Tyler Hoechlin's Superman/Clark Kent. He's there to help with a crisis -- which up until now we had been assuming had to do with Mon-El, an alien who arrived at the end of season one in a Kryptonian escape pod like the ones that brought Superman and Supergirl to Earth.

Instead, it seems as though the two are unconnected. Could the more immediate threat to National City deal with Metallo, who we know will be a villain the two Kryptonians face at least at some point during the first two episodes of the season?

You can check it out below.

THE CW HAS A NEW HERO AND SHE’S BRINGING SUPERMAN WITH HER — When a new threat emerges in National City, Kara/Supergirl (Melissa Benoist) teams up with her cousin, Clark Kent/Superman (guest star Tyler Hoechlin), to stop it. Kara is thrilled to have family in town but it leaves Alex (Chyler Leigh) feeling a bit left out.

Meanwhile, Hank (David Harewood) and Supergirl are stunned by the pod that came crashing to Earth.

Glen Winter directed the episode with story by Greg Berlanti & Andrew Kreisberg and teleplay by Andrew Kreisberg & Jessica Queller.

Supergirl airs Monday nights at 8 p.m. ET/PT. New episodes start October 10 on The CW. The season two premiere will have an encore performance Friday night at 8 p.m.
