Weapon: Death Penalty Cerberus - With every kill, his three barrelled Cerberus gains more strength and power.
Gun Range: Vincent can use any type of gun imaginable.
Abilities: Shape Shifting - Vincent can change forms into a Galian Beast. Mauling his opponent with claws, teeth. His strength and body are almost impenatrable.
Chaos - Vincent has the Chaos gene embedded into his body. When transforming into Chaos, his whole appearance changes. Chaos is suppossed to be the Harbringer of death. However, while Chaos is inside Vincent, Vincents wants and desires seem to fuel the path for Chaos as well. His actions and needs are met over what Chaos was normally created for.
Hand to hand combat - Vincent has a varying degree of martial art moves, high kicks, kick spins, punches, swift and agile even for a larger man.
Magic - Can use all types of materia. Usually placed inside of his gun. But also has some of the highest magic stats in Final Fantasy 7. Magic from Materia.
Also because of all the experiments Hojo did on him, he has more strength, agility, speed, and awareness than normal humans.
Personality: Normally quiet, but when Vincent has something to say, it is normally something important. Been known as cold, but has a more secretive side of warmth that he sometimes show's his friends, it is a rare occurance. Can actually be quite playful, other than serious sometimes. But that is so rare, and has to be with someone, or people whom he trusts. Mysterious, and seems more gloomy than anything, but that is just the persona that he wears. Quick to action, and very intelligent.
Vincent also has issues with out right trusting people, just from everything that has happened with all the people he knew previously. But once they earn that trust, he will go through any lengths to help them. Likes to help the less fortunate, and also likes to help out in any other way possible. It is obvious when Vincent is angry, he usually can't keep his forms in check. Once Chaos is out, run.
History: About twenty-five to thirty years before Final Fantasy VII, Vincent was a member of the Turks, then known as Shinra Electric Power Company "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. Finding out that Vincent's father had a link with Lucrecita she entered in a relationship with Hojo. Becoming pregnant, and giving birth ultimately to Sephiroth.
Vincent objected to the use of humans — especially Lucrecia — as test subjects. In the interest of science Lucrecia proceeded with the treatment and became sick as a result. 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 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 placed in Lucrecia's laboratory.
Lucrecia put the Protomateria inside Vincent's chest, enabling Vincent to control Chaos to a degree. As a result of the combination with Chaos and the experiments made by Hojo, Vincent acquired superhuman abilities such as increased physical strength, speed, endurance, agility, regeneration, shape-shifting, and other powers.
Hojo had placed Vincent in a coffin, in the Shinra Mansion. In many places (Crisis Core Zack found a sleeping Vincent) and in Final Fantasy 7, Cloud woke the slumbering Vincent. Cloud tells him about Sephiroth, and Vincent, knowing he was the child Lucrecia had conceived, considers it another "sin" and returns to sleep. When Cloud tries to leave, Vincent follows and asks if they will meet Hojo. Cloud confirms, and Vincent agrees to accompany the party with thoughts of claiming revenge.
When the party finds Lucrecia in Lucrecia's Cave, Vincent relives memories from his past, remembering the argument between himself and Hojo over Lucrecia, and Hojo shooting Vincent and experimenting on him. When the party confronts Hojo at the controls of the Sister Ray, Vincent has a small scene where he claims it was Hojo, not him, who was meant to sleep and atone for his sins.
Much later, Vincent meets Red XIII later again at the Forgotten Capital. Red XIII is scared that, due to his long lifespan, he will lose everyone he loves and live a life of loneliness. Vincent comforts him and reveals he will always be with him because he is immortal. They agree he and Red XIII will always meet once a year in Midgar.
During the year following Final Fantasy VII Vincent traveled the world, mysteriously popping in and out, retrieving information and helping those in need, keeping looser connection with his friends than the rest of the party. In 0009 he 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 North Crater, Vincent rescued them and helped them recover, while getting as much information about the remnants as he could.
When Kadaj fights Cloud in the Forgotten City, Vincent rushes in and opens fire at Kadaj while picking up Cloud and carrying him to safety. Resting in a remote part of the forest, Vincent tells Cloud about Geostigma and Sephiroth's impending rebirth. Cloud, still tormented over his guilt at being unable to prevent Aerith's and Zack's deaths, asks Vincent if sins are ever forgiven. Vincent replies with "I've never tried". Cloud decides he will try, and tells Vincent he would "phone in the verdict".
Vincent rescuing Cloud.
Vincent shows up with the rest of AVALANCHE for the battle against Bahamut SIN, asking Tifa where he could buy a cellphone (he apparently is the only member of AVALANCHE without one). Aboard the Shera, Vincent tells the party Kadaj is Sephiroth's "larva form" and would become him, while Cloud duels him atop the Shinra Headquarters' remains. Although the party are eager to help, Vincent says Cloud can handle him alone.
During the bonus feature, "Reminiscence of Final Fantasy VII", Vincent makes a call to Cloud. At some point after Final Fantasy VII: Advent Children Vincent purchased a cellphone, and made a point to relay a message to Yuffie that she has no right to call it.
A year following the events of Final Fantasy VII: Advent Children, in 0010, Vincent is called into duty when the mysterious group Deepground begins attacking people around the world. Vincent and the World Regenesis Organization investigate and find Deepground is a group born from secret experiments underground the Shinra Building trying to awaken the final Weapon, Omega.
To do this, they hunt Vincent because he houses the Protomateria needed to control it. Vincent fights off the constant attacks while trying to solve the mystery of his past and he gets his answers with the help of a young Tsviet named Shelke.
Deepground steals the Protomateria from Vincent's body, and Chaos becomes increasingly unstable within him. A digitized version of Hojo was the plot's mastermind, but Chaos is unleashed and defeats Hojo, Deepground, and Omega. When Vincent concludes his mission, he disappears within the Crystal Cave where Lucrecia lay for quite some time. Cloud's party sends a befriended Shelke to retrieve Vincent, who has made his amends and forgiven himself for his "sin".
Vincent takes control of Chaos.
Dirge of Cerberus -Final Fantasy VII- reveals that when Vincent confronted Hojo he was shot, and turned into a sample for Hojo's metamorphosis experiment. The experiment left Vincent effectively immortal and with the ability to assume various demonic transformations. Hojo considered the experiment a failure because Vincent remained in an unconscious state and Hojo left him for dead. Upon discovering this, Lucrecia took Vincent's body and attempted to save him by implanting the Chaos gene within him. While Vincent was revived by this process, he became Chaos itself and had no control over the form.
The Protomateria appeared and Lucrecia used the Materia to suppress Chaos to allow Vincent to have some control over the transformation. In a flashback, Vincent wakes up on a table in a lab, and looks down to find himself in his Galian Beast form. Hojo reveals he inadvertently saved Vincent's life, because his experiments had made Vincent's body durable enough to house Chaos. It seems the longer Vincent lives the more transformations he can evolve and the stronger they become.
It is ambiguous precisely what happened between Vincent's awakening in the laboratory and the beginning of his extended slumber. In a note written by Hojo in Final Fantasy VII - the first clue provided for uncovering Vincent - he claims to have put Vincent to sleep in the basement himself. While there was originally much conjecture as to whether Vincent's sleep was voluntary versus induced, because of his attitude toward it, and the mystery of his in-game attire and long hair, a flashback scene in Dirge of Cerberus -Final Fantasy VII- clearly illustrates Vincent was experimented on and then immediately put to sleep in his current appearance as a Turk. His change of appearance to his current design is unexplained.
Regardless, of everything that has happened to Vincent. The new world of Gran Pulse is a confusing place. However, his goals have never truly changed. Nobody really truly predicting the way Vincent will ever react to certain things. He does wonder what happened to everyone, and doesn't have any doubts that he will see them all in the future. He expects them to come to him and either ask for help, or try to come to him for advice. But he's not the type to idily sit by. Not for a long time now. Now Vincent just wants to travel this world, and find it's insides and outs. Knowing that nothing can truly stop any kind of mission he sets his mind to. He is still Vincent after all, even if the world has suddenly changed. It's not like he's not used to change, sleeping for 30 years, makes things change for either better or worse.
