Some light has been shed on how "Legends of Tomorrow" will be introduced to the audience as EP Marc Guggenheim spoke with Deadline to talk about the upcoming "Arrow/The Flash" spin-off.

Just like last year, "The Flash" and "Arrow" had a cross-over episode (episode 8) in which both heroes were present and joined forces to take on villains like Boomerang and Rainbow Raider. But this year, it will be a lot bigger says Guggenheim, which confirms that more heroes will participate and they will face a tougher and more sinister opponent.

"There's a lot of things that are really cool about this year's crossover, one of which is the fact that there really is a true 2-part story unlike last year where it was two interconnected episodes where each had their own beginning, middle, and end," said Guggenheim.

"This is a big two-part event, one single bad guy, and it will very clearly launch 'Legends Of Tomorrow.' But at the same time what I think is a lot of fun about it is that it doesn't feel like a backdoor pilot for 'Legends Of Tomorrow.'"

This means that the episode will be simultaneous which means the first part will be aired on a Wednesday and the other will be on a Thursday on both show's respective timeslots.

"It feels like an episode of Flash and then an episode of Arrow. It truly is a 2-hour Flash/Arrow event that just so happens to introduce us to some new characters who will be a big part of "Legends Of Tomorrow,'" he added.

"Legends of Tomorrow" is confirmed to air early next year. The team will be comprised of The Flash, Green Arrow, The Atom, White Canary, Hawkgirl, Hawkman, Firestorm, Captain Cold and Heatwave. They will be led by Rip Hunter, a person from the future.
