EP Andrew Kreisberg says the team-up series "is the crazy ideas" that were too wild for 'Arrow' or 'The Flash.'

Legends descended upon Comic-Con Saturday.

Hall H got a taste of The CW's Legends of Tomorrow, with the stars and producers revealing more about the anticipated Arrow/Flash team-up spinoff — including the news that Hawkman would be added to the roster of characters.

The show centers on Rip Hunter (Arthur Darvill), a time-traveling rogue who has seen a horrible future and assembles a ragtag team to stop Vandal Savage, an immortal villain causing trouble throughout time.

Executive producer Marc Guggenheim revealed the first few episodes of Arrow and The Flash this season would set up how certain characters end up on the spinoff .

"Sara (Caity Lotz) is not dead, or needs to be not dead in order to be on Legends," said Gugenheim. "We're using early episodes of these shows to put characters back on the table."

Lotz, whose Arrow character, Sara Lance/Canary, died in Arrow season three, will be resurrected via the supernatural Lazarus Pits.

"The person who goes into the pit isn't necessarily the person who comes out," said Lotz. "She was already pretty crazy. Now after that, I want her to go nuts."

Guggenheim also teased that thanks to the time travel aspect, the show will go to familiar historical moments.

"We'll be going to some not just incredible places, but some incredible moments," Guggenheim said.

The series features time travel and other sci-fi elements, and executive producer Andrew Kreisberg said that he and the fellow producers will often think something is "too crazy" to work on Arrow and Flash and throw those ideas out.

“Legends of Tomorrow, all it is is the crazy ideas. It’s bonkers.”

Legends stars The Flash's Wentworth Miller (Leonard Snart/Captain Cold), Dominic Purcell (Mick Rory/Heat Wave) and Victor Garber (Dr. Martin Stein/one half of Firestorm). Also signed on are Arrow's Brandon Routh as Ray Palmer/the Atom, as well as Ciara Renee (Kendra Saunders/Hawkgirl) and Franz Drameh (Jay Jackson).

The producers have been hiding Legends of Tomorrow Eastereggs in Arrow and The Flash.

The conversation took place during a massive DC/Warner Bros. TV panel also featuring CBS' Supergirl, Fox's Gotham, and CW's Arrow, The Flash and animated spinoff Vixen.
