Legends of Tomorrow set photo reveals Legion of Doom

There are now four DC Comics adaptations on the CW, and that allows for some super synergy. Producer Greg Berlanti has already revealed a four-way crossover storyline for Arrow, The Flash, Supergirl, and Legends of Tomorrow, but there's also something sinister stirring.

A few months back, the CW (via ScreenRant) revealed that some of the villains from the shows will assemble as the Legion of Doom for the second season of Legends of Tomorrow. Arrow's Malcolm Merlyn (John Barrowman) and Damien Darhk (Neal McDonough) will join The Flash's Reverse-Flash (Matt Letscher) and Captain Cold (Wentworth Miller) to form the evil DC Comics team in season 2.

And although the season premiere is still a month away, Letscher shared an Instagram photo that offers our first look at a pair of the villains together.ScreenRant points out a few key details in the photo. Letscher is wearing his ring, which presumably contains his Reverse-Flash suit, while McDonough's Miami Vice look suggests that the time traveling Legends will encounter Darhk sometime in the '80s.

Meanwhile, Letscher is poised to play the Reverse-Flash again during the "Flashpoint" storyline of The Flash season 3. Check out the first official photosLegends of Tomorrow season 2 premieres Oct. 13.
