Jack is a fictional character in the role-playing video game series Mass Effect by BioWare. Jack appears as a squadmate in Mass Effect 2, and may appear in Mass Effect 3 as a supporting character provided she survives the events of the previous game. Jack is voiced by Courtenay Taylor. Within the series, Jack was orphaned at an early age and was kidnapped by the anthropocentric paramilitary group Cerberus to be exploited as a test subject. Designated Subject Zero by Cerberus, she is considered to be one of the most powerful human biotics in existence in the Mass Effect trilogy as the result of unethical experiments conducted by Cerberus to enhance human biotic ability, though her traumatic experiences have molded her into an antisocial and psychopathic individual.
Although Jack was nominated for a video game character award in 2010, and is a popular subject for fan art and cosplay, she proved to be divisive among video game journalists; the character's depiction in Mass Effect 2 in particular faced criticism for filling out the "edgy" archetype of a villain with a vulnerable side, whereas her appearance in Mass Effect 3 was better received.
