mishima kazuya
Tekken character.
Years before the first Tekken tournament, Kazuya father Heihachi took over the title of Mishima Zaibatsu CEO from his father Jinpachi (who also doubles as Kazuya's grandfather) and tried to toss him from atop a ravine. He eventually succeeded thus still the Zaibatsu CEO.
During the first Tekken tournament, a pissed Kazuya rose up the ravine and fought his way to Heihachi, meeting him in a one on one showdown. Kazuya is victorius and eventually throws his father from the same ravine that Heihachi used to throw him.
He eventually gains the title of Zaibatsu CEO and hosted Tekken 2. Unbeknowst to him, however, Heihachi climbed up the ravine he was thrown from and fought his way to Kazuya. He was eventually defeated by his father, who would later toss him into the mouth of a volcano.
He was eventually revived by the Zaibatsu's rival company, G Corporation, hence why he now has a red left eye. He entered Tekken 4 to fight Heihachi and would later persuade him to find Jin. It was revealed that Jin was imprisoned inside Honmaru. They then enter Honmary so Kazuya can pass the Devil Gene to Jin at the cost of himself losing his Devil persona.
Both he and Heihachi are beaten by Jin but were spared afterwards.
They then woke up only to be ambushed by a swarm of JACK robots, the duo fought them off but Kazuya would later betray Heihachi to see his father's demise. A JACK robot eventually revealed a suicide bomb that blows both Honmaru and Heihachi.
Heihachi is then rumored to be dead according to an unknown man who works as a secret agent under the codename Raven. But in reality, the blast sent him blasting off to a graveyard, not knowing that his father Jinpachi reclaims the title of Zaibatsu CEO from him and hosts Tekken 5.
Jin eventually defeats Jinpachi and claimed his position as Zaibatsu CEO prior to Tekken 6. Not pleased with the results, Kazuya promotes himself to the title of G Corporation CEO and declared war on the Zaibatsu by placing a bounty on Jin's head.
