arrow the flash crossover clock king william tockman robert knepper cw 'Arrow' 'The Flash' crossover episode: Robert Knepper to return as the Clock King

When “Arrow” Season 3 and “The Flash” Season 1 have their crossover episodes this fall, Oliver Queen and Stephen Amell might have to band together if they want to defeat a major foe: William Tockman, the Clock King — played by Robert Knepper — is returning.

The Clock King is expected in episode 7 of “The Flash,” according to TVLine. But he’s not coming alone this time. “We wanted to give Barry a real challenge … Two bad guys!” executive producer Andrew Kreisberg says. This second enemy will be a new character to the series.

Tockman first appeared on “Arrow” in the Season 2 episode, “Time of Death.” Although Oliver and company defeated the villainous clockmaker, Tockman survived the encounter. And now he is coming back.

“Arrow” and “The Flash” will premiere their new seasons on The CW Wednesday, Oct. 8 and Tuesday, Oct. 7, respectively.
