Heroes Collide in New "Flash Vs. Arrow" Crossover Episode Photos

Ever since Barry Allen (Grant Gustin) first appeared on "Arrow," the potential for crossovers between "Arrow" and "The Flash" was incredibly high -- and in December, that potential will be realized in a big way. "Flash vs. Arrow," the December 2 episode of "The Flash," is the highly-anticipated crossover episode between the two series, as Team Arrow heads to Central City to investigate a mysterious boomerang -- likely the signature weapon of Digger Harkness (better known as Captain Boomerang) played by Nick Tarabay.

The CW has released a gallery of images from "Flash vs. Arrow" that see the "Arrow" and "The Flash" casts collide -- as well as the anticipated team-up between the eponymous heroes. Check out the synopsis and photo gallery below.

Barry is thrilled when Oliver, Felicity and Diggle come to Central City to investigate a case involving a deadly boomerang. Excited about teaming up with his friend, Barry asks Oliver if he'd like to help him stop Ray Bivolo (guest star Patrick Sabongui), the meta-human Barry is currently tracking. Bivolo causes people to lose control of their emotions and has been using that skill to rob banks. Unfortunately, the superhero partnership doesn't go as smoothly as Barry expected. When Oliver tells Barry he still has a lot to learn, Barry sets out to prove him wrong by attempting to stop Bivolo alone. However, when Bivolo infects Barry and sets him on a rage rampage, everyone is in danger, and the only one who can stop him is the Arrow. Meanwhile, Iris is furious when Eddie tries to get a task force to stop The Flash, Joe and Dr. Wells agree the Arrow is a bad influence on Barry, and Caitlin and Cisco deal with a new team in S.T.A.R. Labs.

"Arrow vs. Flash" airs December 2 on The CW.
