Though DC’s Legends of Tomorrow really kicked off with the annual Arrow and The Flash crossover event, the new CW superhero drama won’t often cross over with the flagship series.

“It’s intermittent throughout,” executive producer Greg Berlanti said at the Television Critics Association’s press tour on Sunday. “Because they’re a band of time traveling rogues, it’s harder for Arrow and Flash to be connected story wise to it throughout the season. That being said, if you know the histories of Arrow and Flash, it should be extra fun in its own way as we delve deeper and deeper into the characters lives.”

Legends stars Brandon Routh (Ray Palmer/The Atom), Caity Lotz (Sara Lance/White Canary), Wentworth Miller (Leonard Snart/Captain Cold), Dominic Purcell (Mick Rory, Heat Wave), Victor Garber (Martin Stein/Firestorm), Franz Drameh (Jay Jackson/Firestorm), Ciara Renée (Kendra Saunders/Hawkgirl), and Falk Hentschel (Carter Hall/Hawkman) as a disparate group of heroes and villains who are brought together by Time Master Rip Hunter (Arthur Darvill) to defeat immortal threat Vandal Savage (Casper Crump).

However, don’t rule out crossovers completely. The Flash’s Cisco Ramon (Carlos Valdes), Arrow’s Damien Darhk (Neal McDonough), and Ra’s al Ghul (Matt Nable) are all slated to make their way to Legends, while there is a “100 percent chance” that older and/or younger versions of Oliver Queen (Stephen Amell) and Barry Allen (Grant Gustin) will appear, executive producer Phil Klemmer recently told EW. “We will have a couple marked crossover moments that hopefully will keep people satisfied,” he said.

DC’s Legends of Tomorrow will debut Jan. 21 at 8 p.m. ET on The CW.
