Jin Kazama (風間 仁 Kazama Jin?) is one of the main characters of the Tekken series. He is featured on the packaging for the console version of almost every sequel following his introduction in Tekken 3. He has also been the main protagonist for the majority of the following entries ever since his debut in Tekken 3 as he has been trying to end the Mishima Bloodline and save the world from a certain evil, with the exceptions of his role as an anti-villain in Tekken 6 (with Lars Alexandersson taking his role as the protagonist) and a supporting character in Tekken 7 (with Heihachi Mishima and Kazuya Mishima taking the role as the main characters of the game).

Jin is the son of Kazuya Mishima and Jun Kazama, the grandson of Heihachi Mishima and Kazumi Mishima, the adoptive nephew of Lee Chaolan, the half-nephew of Lars Alexandersson, a relative to Asuka Kazama, and the great-grandson of Jinpachi Mishima. The leader of the Mishima Zaibatsu and the man who declared war on the world. Fighting the Devil inside him which gets stronger every day, he yearns to be rid of it once and for all. When his battle is over at last, will he find hope, or despair?

Jin's sudden disappearance has left the Mishima Zaibatsu in a state of chaos, allowing his grandfather Heihachi to reclaim the company in his absence. After his supposed sacrifice on defeating Azazel put him into a comatose state, his body is taken under the UN custody. While unconscious, Jin's Devil Gene goes awry again and destroys the UN's chopper. Waking up in a weakened state, Jin walks aimlessly through the desert beneath the sandstorms of the Middle East. When Arabian soldiers find him, he unconsciously unleashes a devil beam into the sky, which sends the soldiers flying. Jin soon arrives in a market while clutching his right arm, not knowing what he is doing there.

He is about to be captured by the Arabian soldiers who continuously pursue him, only to be rescued by Lars before he collapses. Lars quickly carries Jin into his vehicle and drives away from their pursuers. Jin is later transported to a medical facility owned by Violet Systems to recover from his comatose state. However, Nina Williams, who is forced to work for Heihachi, infiltrates the facility to recover Jin and take him back to the Mishima Zaibatsu. But the plan is foiled by Lee Chaolan, who flies Jin to safety while he remotely destroys the facility. Awakening from his coma after Heihachi's true death, Jin is sent out by Lars to find and kill Kazuya.

He complies, as he is now the only one who can stop his father due to the Devil's blood that runs through his veins, preparing to destroy Kazuya and end the cursed Mishima bloodline once and for all.
