He fiercely despises Hojo for his various immoral actions, and it is the promise of meeting him that stirs him to accompany the party in Final Fantasy VII. Vincent is reluctant to speak, although when he does, he typically has something very important to say.

History: About 25 to thirty years before Final Fantasy VII, Vincent was once a member of the Turks, which was then known as Shinra's "Department of Administrative Research". When he was assigned to supervise the Jenova Project in Nibelheim, he fell in love with a scientist named Lucrecia Crescent, an assistant to Gast Faremis. When he discovered her link to his deceased father, Grimoire Valentine, Lucrecia distance her self from Vincent, ultimately entering a relationship with her associate, Professor Hojo, instead. Lucrecia became pregnant afterward, and Hojo planned to use the fetus as a test subject for the Jenova Project.
Vincent objected to the use of humans — especially Lucrecia — as test subjects. Even so, in the interest of science, Lucrecia proceeded with the treatment and became very sick as a result. Outraged, Vincent confronted Hojo in the Shinra Mansion's underground laboratory and a heated argument ensued. Hojo ended it with treachery, pulling a gun from his lab coat and shooting Vincent in the chest. He proceeded to use Vincent's half-dead body as the subject for experiments involving strengthening the endurance of the human body, and metamorphosis, enabling the body to transform into various monstrous forms. While Hojo did succeed in making Vincent's body stronger, the experiments were a failure because Vincent, though still living, remained in a death-like state.
As a last resort to rehabilitate him, Lucrecia infused the Chaos-tainted Mako into his broken-down body. The procedure worked, as Vincent's body, due to Hojo's previous experiments, was strong enough to become a vessel for Chaos; however, Chaos was completely uncontrollable and was only stopped when the Protomateria had a reaction to Chaos. The Protomateria, discovered by Grimoire alongside Chaos, was theorized by Lucrecia to have been created by the Planet "out of necessity as a means to control Chaos and prolong its own inevitable fate", and was put in Lucrecia's laboratory. She put it inside Vincent's chest, and thus Vincent was able to control Chaos to a degree. Vincent later awakened on the operating table and responded to his modified body with both anguish and rage.
Believing himself responsible for Lucrecia's illness after Sephiroth's birth, Vincent locked himself inside a coffin in the Shinra Mansion basement, where he slept mostly undisturbed for 23 years to atone for his "sins". He constantly relived his "nightmare" as a punishment for his inability to stop Lucrecia from submitting to Hojo's experiment on her unborn baby.
During the year following Final Fantasy VII, Vincent traveled the world, mysteriously popping in and out, retrieving information and helping those in need, keeping even looser connection with his friends than the rest of the party. In 2009, he eventually follows rumors to the Forgotten Capital, where the Remnants of Sephiroth were stationed. After Tseng and Elena were struck down and tortured by the trio at the Northern Crater, Vincent rescued them and helped them recover, while getting as much information about the remnants as he could.
Recently the Chaos and Protomateria fought again, so Vincent left his friends to try to deal with the fighting energies. The Chaos started to turn on him and quickly he felt himself disappear and woke up in the nexus.
