Overview:“Arrow” and “The Flash” have some new superhero company in the CW’s lineup with the addition of “DC’s Legends of Tomorrow.” After seeing what doom the future holds, time-traveling rogue Rip Hunter realizes heroes alone are not enough to prevent the impending catastrophe that threatens the planet. Tasked with recruiting both heroes and villains, Rip brings together a ragtag team of divergent talents, which includes the likes of Sara Lance, Ray Palmer, and Heat Wave. Although the team continually adds and loses members, their goal is always the same — prevent supervillains from destroying time itself.
