G Corporation is a cutting-edge biotech firm making revolutionary advances in the field of bio-genetics research in the Tekken series.
G Corporation accidentally stumbled upon the remains of Kazuya Mishima, who had been thrown into a volcano by his father, Heihachi Mishima, after Kazuya was defeated in The King of Iron Fist Tournament 2. This happened during a routine research mission at Mt. Shirane. Afterwards, Kazuya's body was taken to the G Corporation’s Nebraska research facility.
After being resurrected, Kazuya offered his body as research material for genetic experimentation to investigate, determine, and harness the true mechanism of the Devil that resided within his body.
G Corporation raid
Heihachi Mishima discovered that G Corporation had found the remains of Kazuya, and had extracted and analyzed the genetic data. In fact, Heihachi learned that the G Corporation was in the midst of creating a new life form by using the data. Heihachi himself had intentions of creating the ultimate life form by combining Ogre's DNA with his, but he needed the Devil Gene, something of which only his son, Kazuya, and his grandson, Jin Kazama, possessed.
Heihachi used the Tekken Force to raid G Corporation’s maximum security research laboratory in Nepal on December 25. The bottom floors of the building were completely destroyed. The remaining data storage facility containing file servers was airlifted by a group of heavy-duty helicopters. At the same time, a separate unit, which was led by Heihachi himself, infiltrated the G Corporation underground research facility in Nebraska, where Kazuya Mishima’s remains were supposedly preserved. The operation in Nebraska failed, due to the unexpected intervention of Kazuya Mishima.
Before The King of Iron Fist Tournament 5, many Jack-4s were sent to attack Heihachi and Kazuya at Hon-Maru. Kazuya escaped before one of the Jack-4s self-destructed by transforming into Devil (or Devil Kazuya, which is what Devil is called in Kazuya's Tekken 5 prologue) and flying away through a hole in the wall. Heihachi did not escape, as Kazuya threw him to the Jack-4s before making his escape. The explosion almost killed Heihachi, but he managed to survive. This is most likely revenge for the raids on G Corporation in Nepal and Nebraska.
Kazuya, who was caught up with G Corporation's attack on Hon-Maru, believed that the executives of G Corporation plotted against him as well. At the conclusion of the King of Iron Fist Tournament 5, he killed all the executives of G Corporation that betrayed him before taking the company for himself. Shortly Kazuya's takeover, Jin declared the Mishima Zaibatsu's independence and waged war against the world
Unable to accept a world ruled by someone other than himself, Kazuya publicly announced G Corporation's decision to fight the Zaibatsu and was celebrated as a hero. Recruiting his previous subordinates, Anna Williams and Bruce Irvin, Kazuya released a large bounty on Jin's head, who responded by announcing the King of Iron Fist Tournament 6.
War Against Heihachi
Near the end of the sixth tournament, Jin mysteriously disappeared. Without its leader, the Mishima Zaibatsu began losing progressively against G Corporation until the arrival of Heihachi, who took control of the company from Nina Williams. After Heihachi retook the Zaibatsu, he publicly revealed the Kazuya's Devil Gene to the world in an attempt to destroy the Kazuya's reputation as a hero against the Zaibatsu.
During Kazuya's fight against Akuma, who had invaded the corporation to kill him, G Corporation's Millennium Tower was destroyed by a laser fired from the Mishima Zaibatsu's space station. In retaliation, Kazuya destroyed the space station and pinned the blame of the disaster on the Zaibatsu.
The physicist Jane was protected by Gun Jack when the Tekken Force attacked her inside Mishima Zaibatsu Heavy Industries. A G Corporation freighter saved her the next day. She became an engineer for G Corporation, developing Jack-4, as well as Jack-5, Jack-4's successor. G Corporation sent Jack-5 to The King of Iron Fist Tournament 5 for field testing. After Jack-5's memories are restored, she creates the sixth model which is Jack-6 after being demanded about making another JACK model after Jack-5. G Corporation sent Jack-6 to The King of Iron Fist Tournament 6 to stop against the Mishima Zaibatsu.
In the events of Tekken 7, Jane and her team is revealed to be in competition with another research team, who is developing the new biotechnological weapon named Gigas. Both teams entered their weapons into the King of Iron Fist Tournament to decide once and for all which was the best.
