A new promo for "Flash's" second season has zoomed online and it comes loaded with a number of tantalizing tidbits. There's Dr. Martin Stein telling Cisco that he has a special gift, the reveal of Jay Garrick's superhero name (Crimson Comet) and -- the biggest tease of all -- a glimpse of this year's big bad, Zoom.

Crimson Comet is a seldom-used nickname for the Flash, so it makes sense that the show's Jay Garrick would use that moniker in his dimension. Zoom, this season's antagonist, remains a mystery; we know that Tony Todd will provide the voice for Zoom but it's not yet been revealed who -- if anyone -- will play the physical embodiment of the character.

"The Flash" speeds back onto the airwaves on October 6.
