Akuma (悪魔 Akuma?, "Devil"), also known as Gouki (豪鬼 Gōki?, "Great Demon", "Great Devil" or "Great Ogre") in Japan, is a licensed guest character appearing only in Tekken 7: Fated Retribution, and one of the major antagonists of the game. He is also a secret final boss to the game's arcade mode.
A mysterious fighter… a demon. He finds himself in the middle of the Mishima blood feud by a pre-existing relationship with Kazumi Mishima, Heihachi's wife. He makes his debut in Tekken 7 promising to fulfill a debt owed to Kazumi.
Sometime after Heihachi reclaimed the Mishima Zaibatsu, Akuma watches from a distance as an air raid destroys an entire city. He then confronts his target at the Mishima dojo, but their battle is interrupted by a Jack-6 army sent by Kazuya. The two of them temporarily join forces to defeat the onslaught of robots. Afterwards, Akuma introduces himself to Heihachi and explains that he was sent by the late Kazumi to kill both her husband and son. Upon asked by Heihachi about why he waited so long to fulfill the promise, Akuma replies that he was waiting until Heihachi had become stronger. Emerging victorious, Akuma seemingly kills Heihachi and destroys the Mishima dojo.
He later goes to the top of G Corporation tower to fight and kill Kazuya. Gaining the upper hand in the fight, Akuma forces Kazuya into a corner, prompting him to transform into Devil. However, before there is a victor, their fight is interrupted by Heihachi, who had survived and faked his death. The Mishima Zaibatsu CEO fires a power laser from a space satellite, destroying G Corporation tower.
Akuma survives the attack, and confronts Kazuya once more in the volcanic pit after Kazuya killed Heihachi. With his opponent in his devil form, Akuma finds himself locked in an intense fight. The battle reaches its climax when Akuma fires a Hadoken at Kazuya's devil beam attack, destroying the volcanic surroundings. The final outcome of the fight is unknown.
As Akuma is originally from Street Fighter, he possess the elements of his fighting style that are associated with that series. His trademark attacks are the staples of all the practitioners of his fighting style: the Gou Hadoken (a wave of spirit energy fired from the hands that acts as a ranged attack; Akuma can also imbue the attack with thermal energy, creating the Shakunetsu Hadoken), the Gou Shoryuken (a rising reverse-hand uppercut that can hit one or three times), and the Tatsumaki Zankuu Kyaku (a move where the user spins themselves through the air with their leg outstreched, kicking their opponent several times). Of the practitioners of his style, he also possesses unique moves such as the Zankuu Hadoken (a jumping variation of the Hadoken that the user throws at an angle as he descends) and Ashura Senkuu (a move that allows the user to phase forward or backwards, immune to attack until they cease). He also possesses a diving kick called the Tenma Kujin Kyaku that allows him to stop his forward momentum in air and come down with a sharp kick from above.
Akuma's Power Crush move is derived from his Focus Attack (a technique that serves a similar purpose to the Power Crush in the Street Fighter IV series). Unlike the other Tekken 7: Fated Retribution fighters, Akuma does not have a Rage Drive. Instead he is governed by a separate bar at the bottom of the screen. This bar can be used to enhance the properties of his moves (referred to as "EX moves", a concept lifted from Street Fighter III: 2nd Impact) or, when full, execute a "Super Combo" that drains the full bar (another feature pulled from Street Fighter; specifically Super Street Fighter II Turbo). Akuma's Super Combo is a much more powerful version of the Gou Hadoken called the "Messatsu Gou Hado". His super meter can also be used to execute a "Focus Attack Dash Cancel" using his Power Crush move by executing a Power Crush in the middle of another attack. Doing this instantly stops the animation of the preceding attack, at which point Akuma can dash forward and combo off the canceled move. This is a mechanic inherited from Street Fighter IV.
Akuma utilizes an unknown type of Ansatsuken as a fighting style. Ansatsuken is not a specific fighting style but instead is a Japanese neologism that refers to any kind of style created that is used with the intention of ending your opponent's life.
Akuma has also embraced the "Satsui no Hado" (殺意の波動 Satsui no Hadō, lit. "Surge of Murderous Intent") (or Dark Hado) that gives him an edge in fighting opponents. Satsui no Hado is an incredibly destructive and deadly surge of energy that Akuma has been able to skillfully employ in battle. Those who are strong enough to embrace the Hado corrupting their body will gain monstrous power arguably stronger than that of the Devil Gene. However, the weak and ill-trained who attempt to embrace it will be driven to the brink of insanity. After spending decades under the influence of the Satsui no Hado, Akuma has been able to learn one of the most forbidden and deadliest moves known to man; the Shun Goku Satsu, an attack that destroys an opponent's soul and renders them permanently deceased.
For Akuma's Rage Art, he appropriately calls upon the most violent and forbidden art in his style, the "Shin Shun Goku Satsu" ("Wrath of the Raging Demon" in the English translation of Street Fighter IV). When executed, Akuma slides forward similar to the Ashura Senkuu and attempts to grab his foe. Should he be successful, Akuma will say "Isshun sengeki!" ("Die One Thousand Deaths!"), clutch them, and the screen will turn black as the opponent is assaulted mercilessly by an unseen force. Once completed, Akuma will be standing over them with his back to the screen and the Japanese character "天" (Ten, lit. "Heaven") will be emblazoned on the back of his karate gi. Since victims of this technique do not say their defeat-quotes, it's implied Akuma have killed the opponent.
To date, his mastery of the Satsui no Hado has enabled him to transform into an even more powerful type of entity, known as Oni. Oni is the form Akuma takes, when the Satsui no Hado completely overtakes him and is much, much more powerful. Akuma in Oni-form is borderline godhood.
