Known information

(Taking a break as Raiden. Will be back later.)

Raiden is the adoptive son of George Sears. He was adopted after his parents were both killed by Solidus early in his childhood. From an early age he was trained to be a soldier and earned several nicknames due to his skill in combat. During The Manhattan Incident, he discovered that George Sears (Solidus Snake) killed his parents. Sometime after this, he was outfitted with a cyborg exoskeleton to keep him alive after being tortured by The Patriots in which they removed part of his head.

Early Years

Although, at first, Raiden believed himself to have no actual combat experience, he regained the memories of his childhood during the Big Shell incident.

Raiden was adopted by Solidus Snake after Solidus killed his parents. He was a child soldier without a past, absent from the databases of the NSA, CIA and FBI. In the 1980's, Raiden fought in the Liberian civil war under Solidus Snake as a killing machine known alternately as the "White Devil" and "Jack the Ripper". Armed with a gun at the age of six, he proved a superior soldier, rising to become captain of the Small Boys Unit at ten.

On April 30th, 2007, Jack met Rosemary during an argument about King Kong. After they parted ways, they met again afterward, shocked that they worked in the same place. Eventually, Jack grew to love Rose deeply, but his harsh experiences had left him melancholic and emotionally distant, and he constantly shut her out of his problems. However, all of this drama was actually a ruse by the Patriots to gain control of Raiden's life, with Rosemary a patriot spy.
The Manhattan Incident

At the beginning of the Big Shell mission, he was shortly referred to as Snake before his codename was quickly changed to Raiden by Colonel Campbell, as the leader of the terrorists was also referring to himself as Solid Snake. The terrorist leader was later revealed to be none other than Raiden's adoptive father, Solidus Snake. Raiden took to the mission with much hesitance, as he had only been trained in VR missions and had no actual field experience and often proved somewhat indecisive at times.

Raiden later met up with Iroquois Pliskin a Lieutenant Junior Grade with the United States Navy SEALs, who was revealed to be the true Solid Snake, who had faked his death two years prior during The Tanker Incident. Raiden and Snake were able to join forces to take down Dead Cell and implant a virus into GW, the Patriots AI that was running Arsenal Gear, an enormous Patriots warship built under the Big Shell. He was then captured by Olga and Snake, but Olga freed him shortly afterward, telling him they needed to use him so Snake could sneak on board. Raiden then met up with Snake, who gave him Olga's High Frequency Blade. The pair battled through Arsenal Gear's Arsenal Tengu commando soldiers before encountering Fortune. Snaked told Raiden to go ahead, with Fortune claiming that Snake was the root of all her misery. Raiden, hesitant at first, left Snake to face Fortune. Raiden went on to battle against the horde of mass-produced versions of Metal Gear RAYs managing to defeat several of the before collapsing from exhaustion. Just as Raiden was about to be killed, Olga came to his aid. By doing this, she revealed herself as an enemy of Solidus, who appeared and killed Olga. Olga's final words were for Raiden to live. As Solidus ordered the remaining RAYs to kill Raiden, the virus planted into GW went into effect, disabling the the RAYs which were disposed by Solidus out of anger.

Later into the mission, it was revealed that Raiden was merely a puppet of The Patriots, and that his entire mission on the Big Shell was a lie, a scripted event cunningly devised by the Patriots. Additionally, the "Colonel" he was speaking to was actually GW, an AI created by the Patriots, posing as Colonel Roy Campbell, created by Raiden's hopes and expectations of Campbell. They told him that he was just a weapon, a creation of the Patriots with no purpose but for what they made him. The AI instructed Raiden to defeat Solidus, which he had no choice but to do, as Solidus planned on launching a nuclear strike which would wipe out Manhattan.

After the fierce battle on top of Federal Hall, it was then revealed that even Rose, Raiden's longtime girlfriend, was a Patriots spy sent to keep tabs on him, who even went as far as to alter her appearance to Raiden's liking so that he would keep her in his life. Raiden solemnly forgave Rose, who had actually fallen in love with him over time, and they agreed to start a new life together.

After Big Shell

Raiden began living together with Rosemary, but the tragic memories of his days as a child soldier started to resurface, causing tension in their relationship and leading him to leave her.

Raiden learned that Olga's daughter, Sunny, was being held in Area 51, and successfully rescued her with the help of the rebellious group, the Paradise Lost, led by Big Mama. After hearing of Rosemary's miscarriage and subsequent remarriage to Roy Campbell, Raiden became despondent. He left Sunny in the care of Otacon and Snake, then began work on retrieving Big Boss' remains from the Patriots for the Paradise Lost Army, leading to his capture. As a prisoner, the Patriots used Raiden as a test subject for experiments in exoskeletal enhancement surgery, during which his lower jaw removed.

With the help of the Paradise Lost Army, Raiden managed to escape his captivity. After undergoing surgery to clear his body of nanomachines, he was successful in reclaiming Big Boss' remains from the Patriots. The enhancements implanted throughout Raiden's body, however, were too severe to allow him to live a normal life again. He elected to disappear from the life of his fiancee, Rosemary. Left to the wander the Earth, Raiden studied scouting techniques under a Native American shaman living in Alaska, also learning to hunt.

Upon receiving orders from Big Mama to assist Snake and lead him to the Paradise Lost Army, Raiden set out into battle once more.
