The Flash season 1 made a habit of introducing one-off villains - usually created by the pilot's particle accelerator explosion - that Barry Allen (Grant Gustin) would face and defeat within a single episode. Although season 2 has seen Barry go up against a number of metahuman villains, it was at the order of major antagonist Zoom (voiced by Tony Todd). The Flash's recent midseason finale brought back a handful of rogues, revealed some of Zoom's plan for Barry, and introduced a new character - who may or may not have metahuman powers at this point.
However, the show's producers are gearing up for the back half of The Flash season 2, with Marco Grazzini already cast as the DC Comics villain Tar Pit. Now, another actor has joined The CW's superhero action drama as a villain expected to appear in a two-episode arc that has been teased as "crazy."
CB is reporting that Adam Stafford (Peter Pan, Neighbours) has been cast as Adam Fells, otherwise known as the DC Comics villain Geomancer. He will appear in the upcoming 13th and 14th episodes of The Flash season 2, and is described as "a dangerous meta-human with the unique ability to create earthquakes.” In a plan to fight Barry and determine the most powerful metahuman in Central City, “Geomancer uses his powers to unleash a string of targeted earthquakes, optimistic that he’ll draw out the Flash.”
TVLine has further insight into the two-episode arc, reporting that executive producer Greg Berlanti finished penning the episodes in November, which he described as "the two craziest episodes that we've ever done — and probably two of my favorite episodes ever." Berlanti went on to say that there's "incredible stuff" for many of the characters including Iris West (Candice Patton) and teased the exciting episodes.
Much of the first run of season 2 episodes of The Flash, as well as fellow CW superhero show Arrow's fourth season, were dedicated to setting up the spinoff, Legends of Tomorrow. The Flash introduced a new character to the partnership of Firestorm, broke Captain Cold out of Iron Heights prison, and introduced Hawkgirl to the CW shared universe - not to mention the Arrow/Flash crossover focused on the centuries-old fight between Hawkgirl, Hawkman, and Legends of Tomorrow villain Vandal Savage. All of this is to say that it seems the back half of The Flash season 2 will focus entirely on Central City's speedster as he goes up against his own villains.
Of course, fans who disliked The Flash's tendency to feature one-and-done villains in its first season may not be excited for this return to form, but it seems Geomancer, at least, will play a larger role in his two-episode arc. Although, given Berlanti's comments, the character's development will likely still defer to that of the main cast, including Iris. While The Flash's strength has always been in the relationships between its main cast, rather than its short-lived villains, it would be compelling to see the show strike a balance between the two when Geomancer arrives.
The Flash will return on Tuesday, January 19, 2016, while Arrow will return on Wednesday, January 20, 2016 and Legends of Tomorrow will see its series premiere on Thursday, January 21, 2016.
