SDCC 2017: Watch the ‘Supergirl’ season 3 trailer

The last we saw of the Supergirl, she was ridding Earth of Daxam’s Queen Rhea, Alex had asked Maggie to marry her, and Mon-El had to leave Earth or risk dying from the poisoned atmosphere.

Interesting tidbits for the upcoming season include the casting of Smallville alum Erica Durance (known best for playing Lois Lane) as Kara’s biological mother. And even though Alex proposed to Maggie, Floriana Lima will only be returning to the series in a more limited capacity.

The cast and producers were on hand at this year’s San Diego Comic-Con, bringing with them new information about Supergirl’s third season and a new teaser trailer to tide fans over until the show comes back in October.

The trailer is packed with action and a lot of good character moments. Check it out above!

The series stars Melissa Benoist, Mehcad Brooks, Chyler Leigh, David Harewood, Jeremy Jordan.

Supergirl season three premieres on Monday, October 9 at 8/7c on the CW.
