DC Comic fans can look forward to an epic crossover between "Arrow" and "The Flash" next week.

During the Dec. 2 episode of "The Flash," titled "Flash vs. Arrow," Oliver, Felicity and Diggle will head to Central City to solve a case involving a deadly boomerang. During their visit, Barry asks Oliver to step in and help him stop a bank robber named Ray Bivolo, a metahuman who has the power to cause people to lose control of their emotions. However, when Barry falls victim to Bivolo's powers, he goes into a fit of rage and strikes out against Oliver.

The crossover will continue the next day on Dec. 3 in an "Arrow" episode titled "The Brave and the Bold," as Oliver, Arsenal and Diggle continue their hunt for the boomerang killer, Digger Harkness. However, Oliver turns to Barry for help when Lyla becomes a target.

"Arrow" star Stephen Amell and "The Flash" star Grant Gustin recently opened up about the crossover episodes.

"Starling City and Central City are very different places. So when I go to Central City, it's very much, 'Alright, I'll tag along. We'll do things your way.' And then the very next night, in our episode, it's 'I'm sorry, we're not in Central City anymore. We're doing things my way. Things are different here,'" said Amell, according to ExtraTV.com. "So it's a really interesting checkpoint for both shows because we're able to teach these big lessons to the characters. So hopefully Oliver comes out of his trip to Central City having learned something and Grant comes out of his trip to Starling City having learned something as well."

Amell also hinted that fans should take the episode title, "Flash vs. Arrow," quite literally and expect to see a showdown between the two vigilantes.

"We are going to fight," he confirmed.

Gustin detailed the circumstances surrounding their face-off, explaining that the metahuman "gets in Barry's head, and he gets whammied.

"Barry's not himself in 'The Flash vs. Arrow,' It was really fun; I got to play a different character, essentially, who was losing his mind. Some truths come to the surface that wouldn't have otherwise, because Barry's been brainwashed, and that's the reason the fight ensues," he explained, according to The Hollywood Reporter.

Gustin went on to tease that the episodes will highlight Barry and Oliver's differences.

"Barry and Oliver are kind of butting heads, but we're seeing them learn how to work together," he said. "It's really funny because they're so different so the conversations they have are hilarious."

Executive producer Andrew Kreisberg also dropped spoilers about the crossovers, telling THR that "If there is anybody who is watching only one of the shows, [this is an opportunity] to sort of check out the other.

"You don't always get that opportunity ... but I really feel like there are so many similarities between the shows, as much as there are differences," Kreisberg continued. "This was such a great opportunity to give the best of everything we do on both shows: it has great Arrow stunts, it has great Flash humor and heart. We're just really excited."

The EP also revealed that Laurel will step into the role of the Black Canary.

"We've been building up to her appearance as the Black Canary. We sort of said that Sara was the Canary, but Laurel is the Black Canary. Episodes 10, 11 and 12 are a three-part trilogy that are about her, and episode 13 I think I can spoil, is called 'Canaries.' For fans of Laurel and for fans of Katie [Cassidy], they're going to get more than their fill after the winter break," said Kreisberg.

In addition, the showrunner hinted that "there's a really big character, emotional moment for Oliver on The Flash side,:

"... [something] that we set up last season and paid off in Flash, and will pay off down the road on Arrow," he teased.
