Jane

Jane (Japanese: ジェーン Jēn, Russian: Яна) is a non-playable minor character in the Tekken series. She is a young girl who was orphaned in a battle zone after the Russian government attacked with a platoon of Jack robots. The unit Jack-2 overcame his programming to protect her, but he was destroyed in the process.

Over the past twenty years, Jane has dedicated her life to finding a way to resurrect her beloved Jack, using the funding of the Mishima Zaibatsu. But after she was attacked by the Tekken Force and saved by Gun Jack, Jane now works for G Corporation. While working for G Corporation, she developed Jack-4 and its successor, Jack-5. She helped the new leader, Kazuya Mishima, create Jack-6.

Jack-2 and a young Jane are playing on a tropical island. A satellite way up in space fires a laser at Jack-2, shutting him down.

Tekken 3
Jack-2 is reborn... When Jane, now a physicist, was eight years old, she was rescued from a bacteriological war by the Russian military robot Jack-2. However, Jack-2 was later destroyed by a satellite weapon as Jane, still a young girl, watched in horror. Jane, now 27, could not forget the nightmare of Jack-2 having collapsed beside her. She spent 10 years restoring Jack-2 to 90% functionality, but it seemed to have lost the human characteristics that set it apart from Jack. Jane worked hard analyzing the program in order to return to Jack-2 the gentle soul which had saved her life. Through detailed analysis, she found that most of Jack-2's programming was created by Mishima Industries, one of the subsidiaries of the Mishima Zaibatsu. Moreover, she discovered a hidden program... 'Project Gun Jack'. It laid the groundwork for a new weapon, a pivot gun. In order to restore Jack-2 completely, Jane had to approach the Mishima Zaibatsu and solve the mystery of the project. She quickly installed the hidden program and brought the newly dubbed Gun Jack to the Mishima Zaibatsu.

Tekken 5
Beloved Jack-5... Two years ago, a physics scientist named Jane tried to sneak into Mishima Industries with Gun Jack. However, they were discovered by a Tekken Force patrol and were fired upon. Gun Jack placed himself in the line of fire to protect Jane. After the hail of bullets stopped, Gun Jack had ceased to move. The day after, Jane was found and rescued by a G Corporation freighter. Jane joined the robotics division of G Corporation and successfully created Jack-4. Jane used data collected from Jack-4 and began work on a newer model, Jack-5. She saw the upcoming King of Iron Fist Tournament as the perfect chance to test the latest model, equipped with state-of-the-art technology.

Tekken 6
Jane successfully restored Jack-5's memory. It was not long until the Mishima Zaibatsu decided to make their own "Jack" model, which was ten times the power of Jack-5. The new G Corporation leader, Kazuya Mishima, also demanded a new "Jack" model, eventually creating Jack-6. They decided to put it into The King of Iron Fist Tournament 6 to destroy the Mishima Zaibatsu.
