If you have been watching Arrow and Flash this season then you might start to realize these guys are encountering a similar enemy. This is the first crossover of the season in which will be a two part series on both Flash and Arrow. Both teams will fight together to bring down the evil and immortal, Vandal Savage.

  

In the all new extended trailer for the special event, we see Barry and his team make their way to Star City to meet with Team Arrow, but we also get the long awaited look of Carter Hall, better known as Hawkman, played by Falk Hentschel. We also see Kendra Saunders embracing her past as Hawkgirl.

The “Flash/Arrow” crossover will take place on December 1st, Flash, and December 2nd, Arrow. These actions will also set up the spin off for Legends of Tomrorow releasing sometime next year. Enjoy the trailer!
