Arrow/Flash Crossover Promo: Vandal Savage Invades Star City, Hawkgirl Takes Flight & More Superhero Sights

Well, this looks super.

The CW has unveiled an extended promo for its upcoming Arrow/Flash crossover, which will set up the midseason spinoff DC’s Legends of Tomorrow.

In the action-packed teaser, Malcolm warns Barry of Legends baddie Vandal Savage (played by Casper Crump), who crashes into — quite literally — Oliver and Felicity’s loft as he searches for Kendra.

Speaking of the winged gal, the trailer also offers up our first glimpse of Hawkgirl taking to the skies, as well as her other half, Hawkman (Falk Hentschel).

The two-night event kicks off with The Flash on Dec. 1 and concludes the following evening on Arrow.
