A chilling new promo for "The Flash" has teased the arrival of a major villain.
Killer Frost is set to make a big entrance on the show.
The villain, who is played by Caitlin Snow regular Danielle Panabaker, makes an spine-chilling arrival in Central City - boasting that she's having fun being bad, reported Digital Spy.
The news comes after it was previously announced that "The Flash" is bringing back one of Barry Allen's archenemies for a rematch in the New Year.
Matt Letscher has been tapped to reprise his role as Eobard Thawne, when the villain seems to rise from the grave in episode 11.
Barry already has enough trouble with another evil speedster in town, now that the mysterious Zoom (Tony Todd) is trying to steal away his power.
"The Flash" returns in January.
