The CW has released 20 new images from The Flash episode 7 titled Power Outage, which brings in both new villain Blackout (Michael Reventar), and also features Arrow villain Clock King in one of the series' many planned crossovers. Both characters are featured in this new gallery, along with the official synopsis:
The Flash goes up against Farooq aka Blackout (guest star Michael Reventar), a metahuman who can harness electricity. During their battle, Farooq zaps The Flash and siphons all his electricity, leaving The Flash without his speed. Dr. Wells, Caitlin and Cisco work to reverse the effects on Barry, but their efforts are disrupted when Farooq comes banging on S.T.A.R. Labs doors in search of Wells, who he blames for his accident. Without Barry's powers to protect them, the group must figure out a way to save themselves from the metahuman. Meanwhile, Tockman manages a coup inside the Central City police department and takes several people hostage, including Joe and Iris. While Iris is sure The Flash will save them, Eddie has a trick up his sleeve.
