Dearly departed antihero Leonard Snart will “return” to Legends of Tomorrow in The CW sophomore’s midseason finale, it was revealed on Tuesday at a press event.

As previously reported, the iconic and nefarious Legion of Doom will vex the Legends (as well as the JSA) this season, populated by the already revealed Damien Darhk and Eobard Thawne aka Reverse-Flash (played by Neal McDonough and Matt Letscher), along with Snart’s Captain Cold alter ego and longtime Arrow frenemy Malcolm Merlyn (who also makes his Legends debut in Episode 8).

Played by Wentworth Miller, who now has a series regular deal across all of The CW’s superhero shows, Snart famously sacrificed his life late in Legends Season 1, so the Captain Cold we meet as part of the Legion of Doom likely is some other, earlier incarnation.

Speaking of the DC TV universe’s Big Bads, it was also confirmed that Arrow’s 100th episode — which marks Part 3 of the CW hero series’ four-way crossover event — will feature both Damien Darhk and Malcolm Merlyn, among the many other (and sometimes improbably) returning faces, which include Moira Queen, Deathstroke and Laurel Lance.

“Everyone who we could have in the episode from a scheduling point of view is in the episode,” says showrunner Marc Guggenheim. “Even the people that we couldn’t have, because of conflicting schedules, are represented.” (With reporting by Vlada Gelman)
