The Flash’s longtime ally Elongated Man – a.k.a. Ralph Dibny – will be joining the team on the CW’s The Flash this season as a recurring character, played by Hartley Sawyer (Glory Daze, Miss 2059).
Elongated Man has the ability to stretch his body to extremes. In the comics he gained this ability by refining a drink that was popular among the contortionists he admired. Presumably in the show it will be related in some way to the accident at Star Labs – in fact, he was named in the first season as one of the people presumed dead from the accident.
