Vincent Valentine was formally a member of the Turk, and during an assignment to overlook a project led by his father Grimoire, he fell in love with Lucrecia, a scientist that assisted his father. When Grimoire died saving Lucrecia's life, Vincent and Lucrecia parted ways until they met again when Vincent was sent to supervise the Jenova Project in Nibelheim. His attempts to court Lucrecia failed again, since she felt too guilty for his father's death. Instead Lucrecia started a relationship with Hojo and was impregnated in order to supply a test subject for an experiment to see what effect Jenova cells had on an unborn child.
"I was frozen in time, but I feel as if my time is just beginning..." - Vincent
Vincent was against the use of humans as guinea pigs, and when Lucrecia suffered harmful effects from the experiment Vincent confronted Hojo. Following a heated argument Hojo shot and killed Vincent, placing his body in a capsule to use for experiments based on Lucrecia's research of the Lifestream. Due to the experiments, Vincent acquired Galian Beast, Hell Masker, and Death Gigas as part of his body, which he had the power to transform into. Lucrecia also brought Vincent in contact with the G-Substance, a contaminated form of Mako, that resulted in Vincent becoming Chaos, which was to pave the way for the Omega WEAPON.
"Too much hope is the opposite of despair... an overpowering love may consume you in the end." - Vincent
