At Comic-Con International in San Diego's panel for Legends of Tomorrow, the CW confirmed stars Wentworth Miller (Captain Cold) and Arthur Darvill (Rip Hunter) would return to the series in a recurring capacity, in addition to Neal McDonough's Damien Darhk, who will be a series regular on the DC Comics-based show.

An official press release notes, "Wentworth Miller and Arthur Darvill (as former Legends Leonard Snart/Captain Cold and Rip Hunter, respectively) will appear in the upcoming season as recurring guest stars, and Neal McDonough returns as a series regular, reprising his role as smug villain Damien Darhk…and a former member of last season’s Legion of Doom."

Check out a synopsis for the series' third season below:

After the defeat of Eobard Thawne and his equally nefarious Legion of Doom, the Legends face a new threat created by their actions at the end of last season. In revisiting a moment in time that they had already participated in, they have essentially fractured the timeline and created anachronisms – a scattering of people, animals, and objects all across time! Our team must find a way to return all the anachronisms to their original timelines before the time stream falls apart. But before our Legends can jump back into action, Rip Hunter and his newly established Time Bureau call their methods into question. With the Time Bureau effectively the new sheriffs in town, the Legends disband – until Mick Rory discovers one of them in the middle of his well-deserved vacation in Aruba. Seeing this as an opportunity to continue their time traveling heroics, Sara wastes no time in getting the Legends back together.

We reunite with billionaire inventor Ray Palmer, the unconventional historian-turned-superhero Nate Heywood, and Professor Martin Stein and Jefferson “Jax” Jackson, who together form the meta-human Firestorm. Once reunited, the Legends will challenge the Time Bureau’s authority over the timeline and insist that however messy their methods may be, some problems are beyond the Bureau’s capabilities. Some problems can only be fixed by Legends.

Returning Tuesday, Oct. 10, on The CW, Legends of Tomorrow stars Victor Garber as Martin Stein, Arthur Darvill as Rip Hunter, Dominic Purcell as Mick Rory/Heat Wave, Caity Lotz as Sara Lance/White Canary, Franz Drameh as Jefferson “Jax” Jackson/Firestorm, Brandon Routh as Ray Palmer/Atom, Maisie Richardson-Sellers as Amaya Jiwe/Vixen, and Nick Zano as Nate Heywood/Steel.
