Arrowverse heroes suit up in new teaser

Not all superheroes require the same amount of time to get ready. 

Ahead of the midseason premieres for the CW's Arrowverse, several characters from Arrow, The Flash, Supergirl, and Legends of Tomorrow are back together again in a new teaser. Although we already saw this season's four-show crossover and this is sort of a broad promo, it's always fun to see these guys interact. Their chemistry is especially easy to see when Oliver (Stephen Amell) chastises Supergirl (Melissa Benoist) and The Flash (Grant Gustin) for being late. They definitely don't need 40 minutes to change into their outfits.

Supergirl returns first with "Legion of Superheroes" on Jan. 15. While trying to heal from injuries she sustained at the hands of Reign, Supergirl is still in a dreamlike state and can't be reached. Meanwhile, Mon-El (Chris Wood) recruits Brainiac-5 (Jesse Rath) to bring her back. 

The Flash is back the following night on Jan. 16 with "The Trial of The Flash." Barry is on trial for the murder of Clifford DeVoe, leaving Iris (Candice Patton) and Joe (Jesse L. Martin) to decide what they're willing to do to keep him out of prison.

And Arrow returns on Jan. 18 with "Divided." Oliver has lost half his team, but he's still confident he, Felicity and Diggle can stop Cayden James (Michael Emerson) and Black Siren (Katie Cassidy). But when he learns something about Cayden, he enlists an unlikely ally.

Legends of Tomorrow will have a new timeslot to allow for the premiere of Black Lightning, then it'll move to Mondays on Feb. 12.
