Heihachi searched for Jin to no avail. However, Heihachi found a photograph during his search that made him curious. The 20-year-old photograph was an image of a burnt corpse covered with laceration wounds. Heihachi paid much attention to the corpse’s back, which had what looked like deformed, protruding wing-like limbs.
Thinking that the picture was of Kazuya, his own son whom he threw into a volcano 20 years ago, Heihachi diverted all his resources into a search for the body. This search led Heihachi to G Corporation, a modern biotech firm making unprecedented advances in the field of biogenetics research.
Heihachi found out that the G Corporation found the corpse and got its genetic data. In fact, Heihachi learned that the company was in the middle of creating a new life form by using the data. Heihachi also determined that Kazuya’s remains and research data were secured at G Corporation’s Nebraska and Nepal research laboratories, respectively.
Friday, 25 December. The Tekken Force raided G Corporation’s maximum security research laboratory in Nepal. The bottom floors of the building were destroyed, and the remaining data storage facility containing file servers was taken away by a group of heavy-duty helicopters.
At the same time, a separate unit led by Heihachi infiltrated the underground research facility in Nebraska, where Kazuya’s remains were preserved. As Heihachi looked from his helicopter, he soon realized that unlike the Nepal facility, the operations in Nebraska were not going according to plan. The tactical status monitor screens showed the first wave of the Tekken Force troops being blown out from the storage room where Kazuya’s remains were supposedly kept.
A silhouette of a large figure slowly emerged from the room... When Heihachi could see clearly enough, he instantly recognized the large figure as Kazuya.
Kazuya was brought back to life in G Corporation’s research facility. After his resurrection, Kazuya offered his body as research material to determine the true nature of the Devil that resided within him. Kazuya’s goal was to combine his two selves into one. Kazuya theorized that if he unified his body with the Devil, he would be able to truly get its powers. He could then finally take revenge against Heihachi and the Mishima Zaibatsu (Financial Empire).
Enraged that Heihachi thwarted his plans, Kazuya obliterated the heavily armed Tekken Force and vanished into the flames of the lab’s wreckage. Heihachi was infuriated by Kazuya’s escape and took out his anger on his hapless subordinates who reported the escape.
Dr. Abel, Heihachi’s lead scientific advisor, urged the enraged Heihachi to quickly find a way to capture Kazuya. Once his anger subsided, Heihachi focused his mind and decided on a plan. An evil smile crept upon his lips.
Two years had passed since The King of Iron Fist Tournament 3. The Mishima Zaibatsu announced The King of Iron Fist Tournament 4 and placed the massive financial empire as the top prize. The champion who manages to defeat Heihachi at the end of the Tournament would inherit the Mishima Zaibatsu.
Well aware that the tournament is just a trap designed to lure him out, Kazuya nevertheless enters - it is his chance to defeat Heihachi
It marked the first game of the Tekken series to have character conversations (aside from Julia's Tekken 3 ending, in which she speaks to Michelle). Some may speak in other languages (in part of Hwoarang's ending, Jin Kazama speaks in English). It is also the first game having each characters to speak in the beginning for Story Mode. In the background, sketches are seen that follow the characters story. Some may appear in the epilogue of a characters ending.
Tekken 5
Tekken 5 is a fighting video game made by Namco for PlayStation 2, PlayStation Portable and PlayStation 3.
After the end of King of Iron Fist Tournament 4, father Kazuya Mishima and son Jin Kazama, battle each other at Honmaru, somewhere in the Mishima estate. Jin quickly beats his father. The oldest Mishima, Heihachi, enters the Honmaru to find his son defeated and asleep. Heihachi and Jin begin to fight. During the fight, Jin begins to show the Devil he got from his father, Kazuya. Just as it appears that Jin will kill Heihachi, Jin suddenly gains control of his body and flies away.
Suddenly, a bunch of "Jack" robots interrupt the battle. Both Kazuya and Heihachi are surprised at the attack, and begin fighting as a team against the Jack robots. During the battle however, Kazuya goes against his father, throws him into the Jack robots and runs away. Raven, watching on top of the cliff, speaks into a headphone and says: ""Heihachi Mishima...is dead.""
After hearing of Heihachi's death, people though that it would bring the end of the Mishima Zaibatsu. However, an unknown person had taken control, and a month later Mishima Zaibatsu announced the opening of The King of Iron Fist Tournament 5.
Following the end of the King of Iron Fist Tournament 4, Heihachi Mishima defeated Kazuya Mishima and led him to Honmaru Temple, planning to let both his son Kazuya and his grandson, Jin Kazama, battle and steal their "Devil Genes". Jin defeats both his father and his grandfather and flies away, leaving the latter two asleep. Shortly after, a group Jack-4 robots invade the Honmaru. The robots were made to take Heihachi's life. At the start, Kazuya and Heihachi fight the Jack-4's as a team, but eventually Kazuya throws Heihachi across the room as soon as he notices that Heihachi is getting tired. Then, Kazuya turns into Devil Kazuya and escapes, leaving Heihachi to deal with the Jack-4's by himself. They quickly explode, leaving Heihach. The explosion brings Heihachi's father Jinpachi Mishima back to life from his 50 year sleep beneath the Temple, and goes to and become head of the Mishima Zaibatsu. A few months later, the King of Iron Fist Tournament 5 is announced. It turns out that Heihachi survived the explosion, and now promises to find out and ""break the neck of the one who started this ridiculous tournament!""
Tekken 5 kept many features from the older games, as well as new features, such as the new "Crush System" and the chance to dress up all chaaracters differently (except for Mokujin). It was also the first Tekken game to have a mini-game that hade a story of its own. It also had stages with no walls like the stages in all the older Tekken games (except for Tekken 4). The stages did not also have all the slopes and uneven ground, like they did in Tekken 4.
Tekken 5.1 was a small upgrade of the original Tekken 5 that was not released on consoles and instead, was only on arcades. It contained different balance changes to characters of the original game. It also fixed the damage done when using fground moves, instead of ground moves doing 100% damage, they now only did 70% damage. The character health bars for this game is a different colour to the health bars on the original Tekken 5.
Tekken: Dark Resurrection (DR for short) is an upgraded version of Tekken 5. It added two new characters, Emily "Lili" Rochefort and Sergei Dragunov, and it also added a returning older character, Armor King. Eddy Gordo also got his own character box, rather than just sharing a character box with Christie Monteiro. Plus, the game had new moves for the characters, as well as some changes to some older moves, in order to balance out the characters more, new customization items to use to dres up the characters, new stages, and new before fight and win animations, as well as some camera angle changes to some older ones. The game also recolored the main outfits of most of the characters, and the game's final boss, Jinpachi Mishima, got a new design, giving him a flame-like appearance, with a horn coming out of his head.
