How will the heroes of The Flash, Arrow, and Legends of Tomorrow react to Supergirl?

In an exclusive sneak peek from the upcoming four-way crossover, Barry (Grant Gustin) and Cisco (Carlos Valdes) bring Supergirl (Melissa Benoist) back to Earth-1 to the assembled Super Friends. They’ll all stand together to fight the Dominators, a technologically advanced alien race hellbent on eliminating the threat of Earth’s metahumans. (Check out new photos from the crossover event here.)

EW was on set for the scene in question, in which 15 characters across Greg Berlanti’s super shows gathered in an airplane hanger that will double for a S.T.A.R. Lab aeronautics facility, but will actually evoke the iconic Hall of Justice. Pick up this week’s issue of Entertainment Weekly to get more info on the event.

The four-night crossover kicks off Nov. 28 with Supergirl at 8 p.m. ET on the CW.
