Players can unlock Vincent by the halfway point of Final Fantasy VII, when Cloud Strife and his allies find him sleeping in a coffin in the basement of Shinra Mansion in Nibelheim. Cloud mentions his quest to stop the game's antagonist, Sephiroth, who Vincent recognizes as the son of Lucrecia Crescent. Vincent joins the group when he learns that they may eventually meet up with Hojo, against whom Vincent has an unexplained vendetta. Later, Vincent finds Lucrecia inside a cave, and his backstory is partly revealed. Vincent was a member of the Turks, an elite group of Shinra agents. While serving as Lucrecia's bodyguard, he then fell in love with her, but she ultimately decided to remain faithful to Hojo, who persuaded her to use her unborn baby in his experiments. When protesting about the nature of these experiments, Vincent was shot by Hojo, who subsequently began to experiment on him as well. This resulted in him not aging and having the ability to transform in various Monsters. Not being able to protect Lucrecia, Vincent felt a strong guilt which led him to his separation. Overcome by guilt, Lucrecia sealed herself away in a Mako crystal. Upon entering the cave in the game, Lucrecia revives and asks Vincent if Sephiroth is still alive, but Vincent lies and tells her that he is dead.
