Fans would normally be enjoying a new episode of The Flash tonight, and Arrow tomorrow, but due to the Thanksgiving holiday, both shows are on a short hiatus. However, your favorite heroes from Central City and Star City will be coming together once again, with a two-night crossover event, starting with The Flash episode Legends of Today on Tuesday, December 1 and the Arrow episode Legends of Yesterday on Wednesday, December 1. Following the extended trailer that debuted last week, The CW unveiled new photos from both episodes that you can check out below.

In The Flash's 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 Renee). After Vandal attacks Kendra and Cisco, they turn to Barry 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 develops a serum to make Barry run faster and asks Jay (guest star Teddy Sears) to test it out.

The Arrow half of the crossover, Legends of Yesterday, follows Oliver and Barry as they take Kendra Saunders and Carter Hall to a remote location to keep them hidden from Vandal Savage while they figure out how to defeat him. Malcolm (John Barrowman) arranges a meeting between Vandal, Green Arrow and The Flash that doesn't go as planned. Meanwhile, Felicity (Emily Bett Rickards), Thea (Willa Holland), Diggle (David Ramsey) and Laurel (Katie Cassidy) work with Team Flash to come up with a weapon powerful enough to destroy Vandal Savage.

Given the titles of both these crossover episodes, and the inclusion of Vandal Savage, Hawkman and Hawkgirl, it seems clear that The CW is using this crossover to set up their next spinoff series, DC's Legends of Tomorrow. The network announced yesterday that DC's Legends of Tomorrow will debut on Thursday, January 21 at 8 PM ET on The CW, giving fans three nights in a row of superhero-centric shows. DC's Legends of Tomorrow also stars Arthur Darvill (Rip Hunter), Franz Drameh (Jax Jackson), Victor Garber (Dr. Martin Stein), Caity Lotz (White Canary), Brandon Routh (Atom), Wentworth Miller (Captain Cold) or Dominic Purcell (Heat Wave), but it isn't known if any of these stars will be featured in the crossover.

Ciara Renee's Hawkgirl has already been featured in a few episodes of The Flash thus far, but this crossover will be the first time we see her transform into Hawkgirl. We also learned from a trailer released last week that the crossover will also include footage from a fan screening of both episodes, including a Q&A with the stars of both shows. We'll be sure to keep you posted with more footage and photos from the upcoming Arrow and The Flash episodes, but for now, take a look at the new photos.
