Faith is a Slayer: a girl endowed with supernatural abilities and destined to battle evil creatures such as vampires and demons. Created as a foil to the protagonist, Buffy Summers, she is a Slayer who comes from a damaged background and often makes the wrong decision. Initially an ally to the main characters, events take a toll on Faith’s sanity and she slips into a villainous role. Later storylines show her feeling remorse for her past crimes, and with Angel’s help she eventually rejoins the side of good in the hopes of achieving redemption.
