Hawkgirl, is that you? OK, it could just as easily be Hawkman who’s got Barry and Oliver looking skyward in the first-look image above — from The CW’s upcoming Arrow/The Flash crossover.

Whatever the case, the reunion of the CW’s costumed crusaders is the start of something big, as it will lead into the spinoff DC’s Legends of Tomorrow (premiering Jan. 21).

Unlike last season’s event, this year’s crossover extravaganza truly plays as a two-parter — with the superhero shows swapping cities. The evidence is in the pictures, which feature the Central City gang holding court in the Arrow lair during the Dec. 1 kickoff.

While Barry looks very happy to see pal Felicity, the drama soon takes a serious turn thanks to the immortal villain Vandal Savage. (You know it’s bad when Oliver has pulled out a gun in lieu of his usual weapons.)

Meanwhile, the Arrow hour on Dec. 2 will play a game of How Many Costumed Crimefighters Can You Fit Into a Room?
