Kara Danvers Black Ambush

Black Ambush is a persona that Kara Danvers adopted during a particularly tumultuous period in her life. In the comic book series "Supergirl" (2016) by writer Dan Jurgens, Kara discovered that she had been subjected to a form of psychological conditioning by an unknown entity. This conditioning allowed her to tap into a darker, more aggressive aspect of her personality, which manifested as the Black Ambush persona.
