Heihachi

Story

The CEO of the Mishima Zaibatsu and the original host of the King of Iron Fist Tournaments, Heihachi is an old but incredibly muscular individual. After losing against his son in the first King of Iron Fist he had to step down from his position in his company. Filled with shame he went and lived in the mountains alongside Kuma. After hearing about a new King of Iron Fist Tournament, he came back and eventually won, killing his son Kazuya in the process.

After taking back his corporate empire, Heihachi expanded his reach all over the world. This would lead him to Central America, where a mysterious being was found, Ogre. Soon after Heihachi learned of his grandson Jin, and understanding that the Ogre feeds on strong souls set about to train him to bait the Ogre into coming out. To do so, he called a new King of the Iron Fist Tournament.

Heihachi, after learning that he could not be combined with the Ogre's blood due to lacking Devil Genes. He decided to seek out both Jin and Kazuya. The G Corporation had gotten a hold of Kazuya's body since his passing. After learning of this, the Tekken forces, a paramilitary branch of the Mishima Zaibatsu, set about breaking into the corporation and retrieving it. They were faced with a revived and angry Kazuya. To bait Kazuya back into his domain, Heihachi establishes a new The King of Iron Fist Tournament.

Heihachi and Kazuya were ambushed soon after the end of the tournament by a group of Jack robots in Hon-Maru and barely managed to live. Kazuya fled before the climax of the fight. Heihachi was caught in a massive explosion but survived. After recovering he learned of a new King of Iron Fist Tournament that had occurred while he was unconscious.

After being stopped by the Tekken forces while trying to enter the Zaibatsu headquarters he comes to know that Jin has taken over the company. Soon after a new King of Iron Fist Tournament is announced and Heihachi is driven to compete and win back his empire.

Personality

Heihachi is a nimble, astute businessman, who is alluring and skillful at manipulating others. He has a brutal sense of humor which makes others find it difficult to tell whether Heihachi is joking or being deadly serious.

Heihachi is obviously cruel as seen from his actions which consist of throwing his five-year-old son off a cliff, ordering the assassination of his former employees, imprisoning his father, killing his wife (albeit in self-defense), shooting his grandson,  frequently resorting to kidnapping and physical intimidation. He is bitterly resented by both Kazuya and Lee, Heihachi's adopted son, thus implying he was cruel to them in their childhood.

Heihachi's desire for power is ravenous, which has comprised plans for world dominance, enhancing his own power through genetic experimentation, trying to attain eternal youth for himself, and fighting against all of his relatives for his own personal gain.

Apart from being exceptionally good at promoting himself well to the public while building a popular image that hides the darker operations of the Zaibatsu, Heihachi is also incredibly persistent, regardless of setbacks and defeats at the hands of his son and grandson, he bides his time and makes astonishing returns to power, demonstrating his guile and mastery at handling crisis situations. Notwithstanding, Heihachi seems to have a caring side to him. His love of animals is seen as he hand-raised two bears and taught them to fight, he is often kind to Xiaoyu, giving her Panda to protect her, and before the Devil Gene took over Kazumi Mishima, Heihachi loved her dearly. 

Although the subject of tragedy, with the Devil Gene tearing his family apart which most likely led him down a darkened path, Heihachi has also beyond a doubt, provoked the troubles he and the Tekken universe face at every moment, and has steadily been the cause behind most of the strife in the games.

Playstyle

Heihachi is one of the best options for aggressive players because of his devastating and over-the-top moves. Most of his best moves have little to no risk, and his damage potential is extremely high. The Demon Uppercut, for example, is a devastating launcher that is simple to execute and nearly impossible to punish if blocked.

Appearance

Heihachi is an elderly, muscular, and powerful man. He has a unique hairstyle across all the Tekken series, with his hair sweeping up from behind his ears, large sideburns, and a mustache. As of Tekken 2, Heihachi has a star-shaped scar on his chest that he received when Kazuya threw him off a cliff at the end of Tekken 1. Initially, his hair is black, but after the 19-year gap between Tekken 2 and Tekken 3, Heihachi aged to have gray hair.
