The Flash S1 Ep 18 - Gender Transformations

Season 1 Episode 18 Who is Harrison Wells?
As Eddie chases the robber, he catches him and they fight. He manages to beat Eddie and escape, but Barry arrives. He warns he can't outrun him, but he claims he doesn't have to. He touches a teenage girl, and transforms into exact image of her. Barry loses the meta in the crowd. Later, Eddie and Barry go see Hannibal Bates' only remaining relative, her grandmother, to learn something about him. She takes them in and offers them coffee. But soon they notice she's gone, and realize Bates was impersonating her. He attempts to escape as a young woman with Eddie chasing him. Wells and Caitlin warn Barry that Bates can't touch him, so he has to run normally. But during the chase, he touches Eddie and transforms into him and shoots two cops, framing Eddie. The event was recorded on a police car camera. As the women are forced to stop in a red light, Bates transforms into a little girl and starts screaming, alerting nearby construction workers into thinking that he's being kidnapped. He manages to escape and Iris and Caitlin can do nothing to stop him. Eventually, Barry corners him and a fight follows, in which Bates transforms into all the people she has turned into, including Caitlin, Iris and Eddie, even Barry as the Flash. Barry eventually defeats him, and injects the serum on him, and he falls unconscious.
