Cyborg [Victor Stone]; Variant [Scarlett Taylor]; Terrence Fisher (villain); Fisher's army; Agent Steve Burch (CIA Agent); Dr. Silas Stone doppelganger; Dr. Sarah Charles; Dr. Thomas Oscar Morrow; Dr. Silas Stone; Aldous (man/machine hybrid, Dr. Stone's captor)
Victor is betrayed by Variant, whom he learns has been working with Fisher, and the accident that led to her being transformed into Variant was a ploy on her part to gain access to Boom Tube technology that could be used to transport Fisher's armies anywhere in the world. When Fisher betrays Variant, she and Vic work together to bring him down. Returning to S.T.A.R. Labs, Variant is taken into custody and is shut down. However, the Dr. Silas Stone doppelganger has plans for her.
