Heihachi Mishima

Heihachi Mishima is one of the main characters in the Tekken series and he debuted in the first game in the series and has returned for all subsequent titles.

Though seen as an anti-villain of the second Tekkengame, he is one of the main antagonists of the series as he is almost always responsible for the events, though his impact on the story has seemed to decrease since Tekken 5 as he has became a minor character to the storyline. But in Tekken 7however, Heihachi is part of the main storyline once again and is also the main protagonist of the game. It was confirmed that he was not the one who started the Mishima feud in the first place, as it was his wife, Kazumi Mishima who started it all. Heihachi is the son of Jinpachi Mishima, the ex-husband of Kazumi Mishima, the father of Kazuya Mishima and Lars Alexandersson, the adoptive father of Lee Chaolan, and the grandfather of Jin Kazama.

Appearance
Heihachi is half-bald with spiky black hair on the sides of his head. In Tekken 3 and onwards his hair is grey due to his old age. However, in the non-canonical spin-off Tekken Tag Tournament 2 and in Tekken 7′s flashbacks sequences, Heihachi is depicted with black hair. Heihachi has thick spiky eyebrows, a mustache, tanned skin and brown eyes.

Personality
The father of Kazuya, a badass extraordinaire who owns two pet bears (both named Kuma) and is a self-made man who owns the Mishima Zaibatsu...after toppling his father Jinpachi. He threw Kazuya into a ravine to see if he would be considered a worthy successor, and riled him up further by adopting Lee Chaolan. Years later, Heihachi created the King of Iron Fist Tournament, where Kazuya entered, kicked his ass, and threw him into the very same ravine where Heihachi threw him before. Heihachi survived, however, writing Kazuya a letter saying "You should have found a steeper cliff." He then hosted a second tournament where he battled Kazuya again, paid him back, and then threw him into a  volcano.

For years, Heihachi built up a good reputation with his Zaibatsu while hiding his own ambitions. When he's approached by his grandson Jin Kazama, who wants to avenge his mother's death at the hands of Ogre, Heihachi uses him to lure Ogre out. Once Jin beats Ogre, Heihachi betrays Jin by shooting him in the head, only to be smacked back by Devil Jin and thrown out of Ogre's temple through a wall. Later he found out that Kazuya was still alive, and hosts the 4th tournament to lure his descendants for his plans. Jin foils his plan, then he gets ambushed by Jack robots, then Kazuya betrays him and the Jack robots self-destruct on him after dogpiling him. Heihachi survived, being no ordinary man, but was rendered unconscious for the entirety of the 5th tournament while Jin took over the Zaibatsu. During  Scenario Campaign, his plans to take back the Zaibatsu are interrupted in their early stages when Lars shows up and confronts him, revealing that he is Heihachi's son from an affair he had in the Netherlands. The two fight, and Heihachi is defeated. As Lars leaves, he surmises that Lars will end up doing his work for him, and continues to lay low. This pays off when, in the end, Jin sacrifices himself to stop the being known as Azazel and Kazuya leaves out of boredom. With Jin out of commission, but still alive unbeknownst to anyone, Heihachi once again seized control of the Zaibatsu. He now continues the war against G Corporation and Kazuya, hoping to engage in one final battle to decide their fate.

Abilities
With so many devastating and over-the-top moves, Heihachi is one of the best choices for players who like aggressive strategies. His damage potential is insanely high, and most of his best moves have little to no risk. For example, his infamous Demon Uppercut is a very damaging launcher, easy to perform, and almost impossible to punish if blocked.

Unlike Kazuya, Heihachi doesn't have any troubles into pressuring the opponent with pokes, and like every Mishima, he has great punishers, although Kazuya's and Devil Jin's are much more varied and useful.\

Heihachi fights using Mishima Style Fighting Karate. His style is similar to Gojuryu Karate.
