The Flash’ hung around this week, despite a “Power Outage” and the approaching holiday festivities, but December 2 will see the Scarlet Speedster really heating things up when Oliver Queen comes to town for two-part crossover “Flash vs. Arrow.” We’ve seen the photos, but watch for yourself what happens when Barry takes on the emerald archer in the first “Flash vs. Arrow” trailer!

There’s a lot to take in from the minute-long trailer for ‘The Flash’ half of the two-night crossover, but there’s definitely palpable energy in the air as Oliver brings his own grittier set of skills to Central City. In addition to literally shooting Barry in the back (twice!), we also see Joe none-too-pleased by the Arrow’s methods apprehending a bank robber, all before Barry and Oliver end up coming to super-speed blows.

So reads The CW’s official description of “Flash vs. Arrow”:

Barry (Grant Gustin) is thrilled when Oliver (guest star Stephen Amell), Felicity (guest star Emily Bett Rickards) and Diggle (guest star David Ramsey) 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, 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 (Candice Patton) is furious when Eddie (Rick Cosnett) tries to get a task force to stop The Flash; Joe and Dr. Wells (Tom Cavanagh) agree the Arrow is a bad influence on Barry; and Caitlin and Cisco deal with a new team in S.T.A.R. Labs.

The crossover will continue the following night with “The Brave and the Bold,” but in the meantime, take a look at the epic “Flash vs. Arrow” crossover trailer above, and tell us in the comments who you think will win the day on December 2!
