Akuma (悪魔 Akuma?, "Devil"), known in Japanese version of the video game media as Gouki (豪鬼 Gōki?, "Great Demon", "Great Devil" or "Great Ogre") is a guest character from Capcom's Street Fighter series appearing in Tekken 7: Fated Retribution, and acts as a secret final boss to the game's arcade mode.
- Kazumi Mishima - Indebted to her by unknown circumstances, Akuma promised her that he would kill Heihachi Mishima and Kazuya Mishima.
- Ogre - Ogre is Akuma's rival in Street Fighter X Tekken (non-canon).
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 decends) 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 Attack. 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".
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" (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 but not yet master. Those who are strong enough to embrace the Hado corrupting their body will gain monstrous power. 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 permanently destroys an opponent's soul.
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!" ("Prepare yourself!"), 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 "Ten" will be emblazoned on the back of his karate gi.
- His presence in Tekken 7: Fated Retribution foreshadows the process of Namco Bandai's own crossover game with Capcom, Tekken X Street Fighter.
- His current voice actor, Taketora is also the voice actor of Panda in the movie, Tekken: Blood Vengeance.
- In Tekken 7 for being a character from Street Fighter, Akuma is the only character to have special move cancel, Focus Attack, and EX/Super gauge (in place of Rage Attack).
- Akuma's CGI as the secret final boss of the game has seen glowing in a purple aura before the player fights him in the final stage.
- When Akuma is defeated in the secret final boss stage, Akuma's body is glowing in purple miasma due to being succumbed to the Satsui no Hado while unleashing his massive demonic power before the start of the credits.
- In (Ultimate) Marvel vs. Capcom 3 (: Fate of Two Worlds) and Street Fighter X Tekken, Akuma is called as in either his international name, or his Japanese name, Gouki, depends on which region some of these two games players owned or depends on which subtitles the player choose.
- The Abandoned Temple stage has a pair of Nio statues overlooking the stage. These are guardians in Buddhist mythology who watch over sacred Buddhist sites. Akuma's design as a character is heavily inspired by these, hence their appearance on "his" stage.
