Jin Kazama
Jin’s disinterest in close relations probably results from the Devil Gene. As a result of his family’s bloodline curse, Jin thinks that the people he loves will likely suffer, if he ever completely becomes brainwashed by the Devil Gene or become one with it like his father. In short, during Tekken 4, Jin planned to destroy his father and grandfather and then himself, dying without children. and to put an end to the Mishima curse once and for all. However, Jin could not go through it after defeating his two predecessors, so it’s unknown if he has given up on this plan completely since he saw the image of his mother Jun.
After the Tekken 6 scenario campaign, Raven found Jin in a desert in a half buried body. His tattoo is still visible on his arm, meaning that he is not free from the Devil Gene. Jin is mostly calm, but can become enraged should the moment of evil arise. At various moments in the series, his words and actions hinted towards bitterness and resentment as well (especially to his grandfather and father, Heihachi Mishima and Kazuya Mishima respectively).
He also has one personality trait which is common with many Japanese action heroes: Once Jin’s mind is focused in any particular direction, it is immensely difficult to get him to change or even notice the events and people around him. People close to him, including Hwoarang and Ling Xiaoyu, are always going to extremes to gain Jin’s attention, and yet, he maintains an indifferent demeanor towards them. Despite that, Jin is a truly good person who avoids his friends for their own safety.
However, he has a reason of his actions. In the events of Tekken 6, Jin uses his new position as the CEO of the Mishima Zaibatsu to throw the world into chaos in hopes of a cure. Although his intentions are entirely benevolent, since he seeks to use this to awaken and then destroy a much greater threat, Azazel, believing that defeating this monster could help get rid of his curse, Jin might have destroyed countless people’s property, ruined many lives and won lots of enemies through his actions. This may mean that Jin (no matter how painful it is for him) is willing to go out of his morals if that is what it takes to save the world.
Jin Kazama is of Japanese ethnicity. He has black hair that spikes at the back of his head, similar to that of his father, Kazuya Mishima. He also sports fringes, like his mother. Jin is also notably muscular with low body fat percentage, evidence of the many years of hard training. His resemblance to his father is so strong, that in early screen showings of Tekken 3 where his character was still unnamed, many fans speculated that he was a young version of Kazuya Mishima, specifically when he was in his early teen years (Tekken 3 and 4, due to their similarities). While Jin inherited his father’s body structure, his face strongly resembles his mother’s. One of Jin’s most prominent aspects is the black mark on one of his arms, a mark that the Devil branded onto him.
During the game, Jin fought and defeated numerous opponents in the tournament. He also fought against his rival, Hwoarang, although it ended in a draw. Despite this, Jin continued on through the tournament and finally arrived at the temple where Ogre was located. Just as he approached the entrance to the temple, Heihachi appeared and forced him to fight in order to lure out Ogre, but kept this from Jin. Instead, he told him that he wanted to test Jin’s abilities and determine whether or not he was strong enough to fight Ogre.
Eventually, Jin defeated his grandfather, and Ogre then appeared before him. Angered by the sight of his mother’s killer, Jin engaged Ogre in a fight, fueled by rage. During the fight, Ogre then absorbed Heihachi’s power allowing him to become True Ogre and the fight continued.
Jin defeated True Ogre and had avenged his mother at last. Suddenly due to the extreme battle True Ogre violently exploded. Mere seconds after his victory, Jin is attacked by Heihachi’s Tekken Force soldiers, and received multiple gunshot wounds. Slowly succumbing to death, Heihachi shot Jin in the head, therefore killing his own grandson. However, when Heihachi turned his back and walked away, he saw the bodies of his soldiers before him, and turned around to see Jin morphed into his devil form, Devil Jin. Jin then slammed Heihachi through a wall of the temple and violently hurled Heihachi down into the ground. Finally, Jin spread his wings and flew off. Heihachi, weakly, sat up and watched as his grandson, Devil Jin, disappeared into the night.
Jin’s thoughts burned with the desire to destroy the evil Mishima bloodline, the bloodline of his grandfather, Heihachi Mishima, and his father, Kazuya.
One day, Jin heard rumors that The King of the Iron Fist Tournament 4 was announced.
A once in a lifetime opportunity to exterminate the Mishima clan… Without hesitation, Jin hardened his resolve to enter the tournament.
After fighting many opponents in the tournament, including Hwoarang near the end where they promised to fight in the next tournament, Jin finally had a match with Kazuya, his father. On his way to fight Kazuya, Jin encountered the Tekken Force soldiers. Jin managed to take down a number of them but was outnumbered and eventually defeated. He was then taken prisoner by the soldiers.
Heihachi’s Tekken Force soldiers held Jin captive at Honmaru. When he arose Jin defeats his father Kazuya, (whom in Jin’s dream is antagonizing him to “give in to the anger”, which would trigger his Devil Gene) and knocked him unconscious. Heihachi then foils Jin’s escape, and challenges him to a fight in an attempt to take Jin’s own Devil Gene from him. The two fought immediately, and Jin proved that he was too much for Heihachi to handle. With Heihachi weakened, he then proceeded with his own mission (which was to destroy his evil bloodline by murdering his grandfather, his father, and then himself), but abruptly paused when he had a hallucination of his mother, Jun Kazama (this could also have been her soul reaching out to him). As a result, Jin dropped his grandfather and said, “Thank my mother, Jun Kazama,” before once again flying off into the night.
“If this keeps eating away at me, I don’t know how long I can hold on”.
With nothing else left, Jin went out to end his bloodline.
Jin, once again, fought his rival Hwoarang, but the devil gene began to take over Jin again. During this time Hwoarang took the opportunity to strike and defeated Jin. Devil Jin awakened and defeated Hwoarang afterwards.
Back in his human form, Jin met and battled his great-grandfather, Jinpachi Mishima and in the end defeated him. Jinpachi exploded into nothing but dust, as Jin looked up into the sky (this is possibly where Devil Within takes place). In the end, Jin walks into the Mishima Zaibatsu throne room having claimed the Zaibatsu.
However in the Scenario Campaign mode it is revealed that the war and tournament was just to fill the world with enough negative energy to make the physical form of the evil entity known as Azazel, because Kazuya and Jin are known as the “Two Evil Stars”.
Having been defeated by Lars, Jin tells him why he started the war and revealed to him that Jin has a half-controlled Devil Gene, which gives him no choice but to start a war with Kazuya, in-order to lure Azazel out of seal to save the world from Mishima’s bloodline treachery, and the only thing that could destroy Azazel, is the person who has a devil’s power. Lars tells Jin that he’s already took Azazel out, but he doesn’t understand at all what Jin says as Azazel (in Golden Form) appears before them. Jin then utilized his Devil’s power and sacrifices himself to kill The Gold Azazel for good, to free himself from the evil inside him and save the world. After Jin defeats Azazel, Raven finds Jin’s body lying in the desert. He still bears the Devil tattoo on his arm, indicating that Azazel’s demise has not freed Jin from the Devil Gene. It is unknown that he’s just unconscious or dead.
