Weapon(s)
In SoulCalibur II, Heihachi's arm braces are considered weapons. The default are known as Kiaiissen, said to have been forged from traditional Japanese armor.
Fighting Style(s)
Heihachi is a practitioner of Mishima Style Fighting Karate. Although it is unknown who originated this style, it is used by Heihachi's father, Jinpachi, so it was not Heihachi who founded it. This sub-branch of traditional karate is rife with flashy, showy moves that normally would be restricted to sport or film karate.

The only blood member of the Mishima family to never use the style is Heihachi's illegitimate son, Lars Alexandersson. Heihachi's grandson, Jin Kazama, used it one point, but abandoned it for full-on traditional karate. To date, the only practitioners of the art have either been blood relatives of the Mishima line, or alternate manifestations of one (such as Devil and Angel).

Storyline
King of Iron Fist Tournament
"You fool! I am invincible!"
The original leader of the Mishima Zaibatsu, and the fighter known as the "King of the Iron Fist."

Heihachi continues to fight for control of the Mishima Zaibatsu against his son, Kazuya, and his grandson, Jin.

After having recovered from the injuries he sustained in the suicide attack on him from the G Corporation's Jack units, Heihachi is back with an iron fist--and body to match.

The King of Iron Fist Tournament 2
Beaten by Kazuya in the previous tournament, in an instant he lost both his fame and family. Having spent his previous time indulging in deviant acts instead of training, he vows to regain all he has lost.
The King of Iron Fist Tournament 3
Heihachi retrieved the Mishima Financial Empire by defeating his son.

Scheming to further develop the MFE, Heihachi organized "Tekken Force", the MFE's private corps and dispatched them to settle disputes and brought waste land under cultivation to feed the poor countries of the world to gain support of leaders worldwide.

Fifteen years later, a secret excavation by the Tekken Forces in Central American ruins unearths an unusual find. They were annihilated by a mysterious being.

Heihachi realized that the mysterious being could be the legendary God of Fighting, and took action to realize his life's goal, to capture the God of Fighting and therefore rule the world.

One day, Heihachi was visited by a 15-year-old boy named Jin Kazama. Being informed that Jin was his grandson and hearing what had happened to his mother Jun, Heihachi reasoned that the God of Fighting thrives on the "strong souls" of others. Heihachi trained Jin to use him as a decoy to lure the God of Fighting

In Jin's nineteenth year Heihachi declared to the world that the third 'King of the Iron Fist Tournament' was forthcoming. At the same time he noticed that Jin, the youngest of Mishima bloodline, began to show the same "dangerous power" as Kazuya had. Heihachi decided to dispose of Jin after he lured the God of Fighting in order to end the doomed destiny of the MFE.
The King of Iron Fist Tournament 4
Two years ago, Heihachi failed to capture Ogre, but his researchers succeeded in collecting samples of its blood and tissue. These in turn were used in an attempt to create a new life form by combining Heihachi's and Ogre's genetic material.

The experiment failed, however, and Heihachi learned that he lacked the Devil Gene necessary to integrate Ogre's genome with his own.

In order to obtain the Devil Gene, Heihachi searched for Jin, who had transformed into a devil during the last Tournament.

During his search, Heihachi learned that the body of his son, Kazuya--whom he killed 20 years ago--was stored at a cutting-edge biotech firm called G Corporation.

Heihachi ordered his Tekken Force to raid G Corporation in an attempt to obtain Kazuya's remains. However, the mission ended in failure when Kazuya, revived by G Corporation, retaliated.

In order to create a new life form, Heihachi needed the body of Kazuya or Jin, both of whom carried the Devil Gene.

After much deliberation, an evil smile spread across Heihachi's lips. The next day, The King of Iron Fist Tournament 4 was announced.
The King of Iron Fist Tournament 5
Heihachi Mishima.
The head of the Mishima Zaibatsu and the sponsor of The King of Iron Fist Tournament 4.

A squadron of JACKs cornered Heihachi after his loss to Jin Kazama in Honmaru.

At first, Heihachi and Kazuya fought the JACKs together. But Kazuya fled, leaving Heihachi to battle the JACKs alone.

The fight would have killed an ordinary human. But Heihachi, no ordinary man, held off the JACKs and survived the ambush.

One month later, he learns someone has taken control of Mishima Zaibatsu and opened The King of Iron Fist Tournament 5.
Heihachi prepares to fight again.

"I don't know who's behind this, but the Mishima Zaibatsu is mine!" says Heihachi.
The King of Iron Fist Tournament 6
Heihachi was knocked unconscious when the JACK military unit he was fighting self-destructed. When he came to, The King of Iron Fist Tournament 5 was already over. He went home, without any knowledge of the events that occurred at the tournament, where he was ambushed by the Tekken Force.

Afterward, the Mishima Zaibatsu announced The King of Iron Fist Tournament 6. Heihachi was furious when he heard that Jin had taken control of the Zaibatsu, and he left for the tournament to reclaim control of the Mishima Zaibatsu.
Soul Edge
Soul Calibur 2
After completing his mountain training with Kuma, Heihachi stopped by at a hot springs resort to recuperate. There he encountered an ancient metallic fragment. According to old picture scrolls, this shard was a piece of Soul Edge, a notorious sword from medieval Europe. Heihachi grabbed the fragment in excitement and accidentally cut his fingertip.

After a moment of dizziness passed, Heihachi looked around at his surroundings. A feeling of uneasiness washed over him. He was no longer at the resort he had been at just a few moments ago. Heihachi was stunned, but nevertheless remained collected.

After he wandered around for a while, he came to the conclusion that he was no longer in modern-day Japan. He had somehow traveled back to ancient times. Apparently, he was in the later half of the 16th century.

Regardless of the situation, Heihachi had to find a way to return to his time.

There was a part of him, however, that was trembling with anticipation of what was about to transpire. He knew the history behind the fragment, which was rife with battles between warriors fighting for its possession. Now, he was right in the midst of it all.

What better way to test his strength than a warring era ruled by power? A fighter could not ask for a better challenge!
PlayStation All-Stars Battle Royale
ZAIBATSU MASTERMIND
Heihachi is the head of the Mishima Zaibatsu and responsible for the King of Iron Fist Tournament, attended only by the strongest fighters around the world. A master of Mishima Style Fighting Karate, Heihachi seems to be able to rejuvenate himself, displaying a remarkable agility and strength which defies his true age. His pet bear, Kuma, joins him in battle, adding to the already formidable challenge he presents opponents.
Street Fighter X Tekken
Unstoppable King of Iron Fist
The man known as the King of Iron Fist, a formidable figure whose incredible strength betrays his age. He is usually a callous and heartless individual, but from time to time shows a softer side. He is currently fighting his son Kazuya and his grandson Jin for control of the Mishima Zaibatsu. After discovering that both Jin and Kazuya have begun to search for Pandora, Heihachi begins his own journey to exterminate the two in order to reclaim the Mishima Zaibatsu.

Fun Facts
The "Electric" Wind Godfist
Wether by glitch or intention, performing Kazuya's Tekken 2 Wind Godfist with exact timing made the move more effective. When Jin and Heihachi took over prime Mishima-ship in Tekken 3, an electric spark was added to their Wind Godfist's when pulled off with the necessary timing.
Cross-Company Family Ties
Although precise details on the specifics are hard to find, there is mention in both an issue of Tips & Tricks and the official Ehrgeiz mook that Ken Mishima, AKA Godhand, is indeed a member of the Mishima family of Tekken fame. How exactly he fits in, however, is unknown. The only concrete detail is that the Mishima Construction Company he used to run is a subsidiary of the Mishima Zaibatsu.

Although unconfirmed in the mook, Tips & Tricks indicates that Godhand's status as one of the Mishima clan may be due to Namco's assistance on the title (as evidenced in the credits).
Party Pals
Pac-Man's ill-fated entry to the "Party Game" genre (2002's Pac-Man Fever) featured playable guest characters in the form of fighting game staples Heihachi and Astaroth, as well as the rarely-seen Tiger Jackson. Pac-Man's own wife and Ridge Racer mascot Reiko Nagase rounded out the cast.
Family reunion canceled due to attempted murder
The character name data in both the arcade and PlayStation versions of Ehrgeiz list 三島平八 (Heihachi Mishima) and 一八DEVIL (Kazuya Devil), giving further credence to the notion that Godhand is a member of the Tekken Mishima clan.
