The Flash, Arrow and Legends of Tomorrow are all converging tonight on the first of a two-part crossover episode that will focus on Hawkman and Hawkgirl's backstory and how it relates to Vandal Savage.

So far, Cisco has gotten a vibe that his new love interest, Kendra Saunders (Ciara Renee), is more than just a waitress in a coffee shop. Tonight we'll see spread her wings, but before we do, let's take a look at this brilliant concept art of Hawkgirl's costume that Andy Poon illustrated for costume designer Maya Mani.

PART ONE OF THE EPIC CROSSOVER WITH “ARROW” — In its second major crossover event with “Arrow,” Vandal Savage (guest star Casper Crump) arrives in Central City and sets his sights on Kendra Saunders (guest star Ciara Renée). After Vandal attacks Kendra and Cisco (Carlos Valdes), they turn to Barry (Grant Gustin) for help. Realizing how dangerous Vandal is, Barry takes Kendra to Star City and asks Oliver and team to hide her until he can figure out how to stop Vandal. However, things quickly go from bad to worse when a man with wings AKA Hawkman (guest star Falk Hentschel) shows up and flies off with Kendra. Meanwhile, Harrison (Tom Cavanagh) develops a serum to make Barry run faster and asks Jay (guest star Teddy Sears) to test it out. Ralph Hemecker directed the episode with story by Greg Berlanti & Andrew Kreisberg and teleplay by Aaron Helbing & Todd Helbing (#208). Original airdate 12/1/2015.
