The Flash Arrow crossover episodes has already identified its villain. According to a synopsis released for the first crossover episode set on December 2, Ray Bivolo, a.k.a. Rainbow Raider, will be the one that will keep Grant Gustin's Barry Allen and Stephen Amell's Oliver Queen busy. This new villain will be played by Canadian actor Paul Anthony.
Rainbow Raider is not the only villain that the Flash and the Arrow will share. Captain Boomerang, who is more known in the comics world as the enemy of the scarlet speedster, will pay one of Oliver Queen's friends a visit. According to The Flash Arrow crossover episode spoiler from TV Line, fans should watch out to whom Capt. Boomerang (to be played by Spartacus star Nick Tarabay) is connected to.

Question: Any scoop on next month's Flash/Arrow crossover? -Mason
Ausiello: We'll learn that The Flash's Captain Boomerang (played by Spartacus vet Nick Tarabay) has a surprising connection to Starling City. As exec producer Greg Berlanti teases: "He's got a relationship to one of our recurring [Arrow] characters, but I shouldn't say who." Yes, you should, GB! Grrr.
Aside from Captain Boomerang, one more villain is going to terrorize Central City. This enemy, however, may not be seen in the Flash Arrow crossover episodes. Barry Allen is very familiar with him though as he already appeared in the pilot episode. His name is Weather Wizard.

"The Weather Wizard is returning! No, not the one that brewed a storm in the pilot - his brother. Turns out that Mark Mardon survived the same plane crash that his kin was in, and as such possesses the same, but lethally refined, weather-controlling powers. Oh, and he wants Detective West (AKA Clyde's killer) dead. "
