[Mild SPOILERS for the upcoming Arrow/Flash crossover ahead.]
The CW's DC Comics-based TV series Arrow and The Flash are currently on their fourth and second seasons, respectively, and will soon cross paths directly again, having already done so in the past (see episodes like "The Brave and the Bold" and "Rogue Air", among others). However, the TV shows' next crossover will perhaps be their most important to date, seeing as it will lay the foundation for The CW's upcoming third addition to its DC TV-universe, titled DC's Legends of Tomorrow.
Legends of Tomorrow, as created by Arrow/Flash masterminds Greg Berlanti, Andrew Kreisberg, and Marc Guggenheim, will revolve around a team of second-tier superheroes from the CW/DC-verse - including Sarah Lance/White Canary (Caity Lotz), Ray Palmer/Atom (Brandon Routh), and Dr. Martin Stein/Firestorm (Victor Garber) - who work together in order to stop the supervillain Vandal Savage (Casper Crump). Newly-released plot summaries for said upcoming Arrow/Flash crossover episodes have now revealed how that two-parter will serve as a prologue (of sorts) to the events in Legends of Tomorrow.
A recently-unveiled image from the upcoming Arrow/Flash crossover - which encompasses the Flash episode "Legends of Today" and Arrow episode "Legends of Yesterday" (notice the trend?) - confirmed that both Kendra Saunders/Hawkgirl (Ciara Renée) and Carter Hall/Hawkman (Falk Hentschel) will in fact be appearing during the two-part event, before they too appear on Legends of Tomorrow. You can check out the full superhero lineup for the Arrow/Flash event in said image, below:
For more on how these pieces will fit together, you should read through the synopsis for "Legends of Today" - as penned by Aaron and Todd Helbring (based on a screen story by Berlanti and Kreisberg) and directed by Ralph Hemecker:
“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, 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.”
Now, here is the synopsis for "Legends of Yesterday", as penned by Guggenheim and Brian Ford Sullvain (based on a screen story by Berlanti and Guggenheim) and directed by Thor Freudenthal:
“Oliver and Barry Allen 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 arranges a meeting between Vandal, Green Arrow and The Flash that doesn’t go as planned. Meanwhile, Felicity, Thea, Diggle and Laurel work with Team Flash to come up with a weapon powerful enough to destroy Vandal Savage.”
Recent developments in the CW/DC universe - such as John Constantine (Matt Ryan) showing up on Arrow to assist with the newly-resurrected Sarah and/or the S.T.A.R. Labs team from The Flash helping Firestorm/Dr. Stein to find a new partner to deal with his unique status - have continued to expand the shared mythology of the CW's DC superhero series, while simultaneously weaving the narrative threads that will eventually be picked up in Legends of Tomorrow. It's probably for the best that characters like Vandal Savage and Hawkman/Hawkgirl will be firmly established before the latter series gets started, in order to allows viewers to keep up with things once more factors - see time-traveler Rip Hunter (Arthur Darvill) - get thrown into the larger equation here, too.
For the time being, Legends of Tomorrow is the only Arrow/Flash spinoff that the minds over at the CW has planned - just how Legends connects with and/or affects events on Arrow and The Flash hereon out, though, that remains to be seen. Similarly, depending on how this new CW/DC TV show goes over, additional spinoffs may no longer be outside the realm of possibility... for better or worse. As always, we'll keep you posted on the situation.
The Flash episode, "Legends of Today", will air on The CW on Tuesday, December 1st. The Arrow episode, "Legends of Yesterday", will air a day later, on December 2nd. DC's Legends of Tomorrow is expected to premiere on The CW in early 2016.
