Last season, "Legends of Tomorrow" was about a group of renegades trying to stop a mad tyrant from taking over the world. They succeeded, but in doing so they destroyed the Time Council (who, let's face it, weren't the nicest of people). Season two will see the team stepping up as the new custodians of history, but that doesn't mean they are giving up their roguish ways.

In an interview with Entertainment Weekly, executive producer Marc Guggenheim teases some big changes for our team of time travelers. "We pick up six months later, and the Legends are acting like time cops. They’re going around history, fixing aberrations, dealing with time pirates, all sorts of fun things... Something happens in the premiere that changes the game for them, and we’re going to end up with a shift in leadership away from Rip into the hands of someone new."

He doesn't go so far to say who that someone is, but the decision makes a lot of sense. Last season, Rip Hunter's motivations were highly personal. He sought to avenge his family. With Savage out of the picture, it gives the show some room to adjust course and tell different sorts of stories.

Guggenheim goes so far to say, "Fundamentally, we wanted to reinvent the show, and almost treat season 2 like a new season 1."

The most exciting news though, may be about the formation of the Legion of Doom. Featuring Malcolm Merlyn, Damien Darhk, the Reverse Flash, and the returning Captain Cold, Guggenheim had this to say: "They all have different agendas. They’re brought together by Eobard Thawne, he’s the one that brings them together, and we’ll discover why Thawne, Speedster, the Reverse-Flash, a very impressive big bad in his own right, needs the help."
