The Flash Season 2 Spoilers: Everything You Need To Know
3. Zoom Is Coming
Reverse-Flash was an excellent big bad for season 1 of the show, and they aren't straying too far away from that in the second year, at least not in terms of having the overarching villain be a speedster.
Where Zoom differs, though, is that rather than running really fast, he alters the speed of time itself, meaning he is actually faster than Barry Allen. Although often wearing a yellow suit in the comics, it appears as though he'll be blue here, presumably just to differ from last year's Reverse-Flash (though that could just be the blue trail he leaves when running, rather than his costume).
Although the teasers have said that 'Zoom is coming', he will be something of a mystery for much of the season. Tony Todd, famous for playing the Candyman in the film of the same name, has been cast as only the voice of Zoom, and a large part of the villain's arc will be centred around trying to uncover just who that voice really belongs to.
