It was announced earlier this year that Arrow and The Flash do exist in the same universe and WILL be crossing over early in the first season of The Flash. But it seems that Arrow and Flash will be sharing a little bit more than a universe. TV Line reports that Robert Knepper will once again be playing the role of William Tockman, The Clock King, and will be squaring off against The Flash in 7th episode of the first season.
Executive producer Andrew Kreisberg tells that Barry will not only be battling The Clock King but a SECOND VILLAIN to go along with it, saying that he “Wants to give Barry a real challenge. Fighting both a new enemy and one of our scariest and most successful Arrow villains in The Clock King”. Clock King alone is an interesting match for The Flash. The fastest man alive competing against the master of perfect timing.
While the villain who will be alongside William is still unnamed at the moment, surely fans are still very excited for the this story and others that will unfold in The Flash. As the old saying goes “Anticipation is half the fun”.
