A new promo for "Blood Bonds," "Supergirl's" 2016 premiere, has arrived
. It's a quick, 20-second teaser that manages to pack in a lot of big moments, including a glimpse of Kara's reaction to learning that Hank Henshaw is the Martian Manhunter, a look at Toyman's doll of destruction and a revisitation of Cat Grant asserting that National City's resident hero and her assistant are one and the same.

"Supergirl" returns to CBS on Monday, January 4 at 8 p.m. EST. Developed by producers Greg Berlanti, Ali Adler and Andrew Kreisberg, the series stars Melissa Benoist, Calista Flockhart, David Harewood and Chyler Leigh.
