So, unfortunately for Barry Allen (Grant Gustin) and fans of "The Flash," the speedster superhero has traded one arch nemesis, Reverse-Flash (Tom Cavanaugh), for another in Season 2. However, something familiar about the show's new chief bad guy may have some observant fans claiming déjà vu.

According to Variety, "The Flash" has cast actor Tony Todd to play the central role of supervillain Zoom in the new episodes. Todd, who is best known for his work in "Candyman" and the "Final Destination" series, will make his debut appearance in episode 2 of the CW series' sophomore run, titled "Flash of Two Worlds." 

Here is where it gets interesting. Comic fans know Zoom as Eobard Thawne, a fan of the Flash's from the 25th century who develops the same powers by replicating the electrical jolt that gave Barry his super speed. He then uses that speed to travel into the past to meet his hero, but becoming mentally unstable in the process, decides instead to take on the Flash as his rival, thus become Reverse Flash (sometimes called Professor Zoom). If that sounds familiar, that is because Barry already spent Season 1 battling an Eobard Thawne who moonlighted as Reverse Flash -- Harrison Wells. The different casting would indicate that this is not Tom Cavanaugh's Thawne making a return appearance, but the show has not yet explained the apparent copy cat speedster.

Whatever the situation, Barry will have some help taking on Zoom. It was previously announced that Violett Beane has been tapped to play Jesse Quick, the show's first female speedster and a college student who becomes entangled in the battle between Barry and Zoom after meeting Barry at S.T.A.R. Labs. At least the Flash will not be outnumbered. 

Todd's Zoom joins several new faces on the new season of "The Flash," including a whole team of new speedsters -- Beane as Jesse Quick, Keiynan Lonsdale as Wally West, and Teddy Sears as Jay Garrick -- a new love interest for Barry, Patty Spivot (Shantel VanSanten), and other new bad guys, including, Atom Smasher (Adam Copeland).

Will Barry be able to stop Zoom? And what should viewers make of Eobard Thawne 2.0? Fans will have to wait to find out. "The Flash" returns to the CW for Season 2 on Oct. 6.
