Gohadoken (豪波動拳, Gouhadouken, "Great Surge Fist") is a more powerful version of the Hadoken used by Akuma, Gouken and Oni. Gouken's version is written with the kanji '剛' instead of '豪', changing the meaning to "Strong Surge Fist."
In the storyline, this Hadoken is a life-threatening technique (though not as potent as the Goshoryuken used by Akuma, or some of the more powerful moves in that tier), but the lethality of the Gohadoken is increased whenever the Satsui no Hado is being embraced. The gauge of the Gohadoken depends on how attuned the user is to the Chikara no Hado or the Satsui no Hado.
|Gouken and Oni||+ ( to charge)|
Executed in the same way as the original Hadoken (with Gouken and Oni able to charge by holding the punch button), the user fires a projectile that travels in a straight line toward the opponent. In some games, Akuma's Gohadoken does more damage at point-blank range.
Gouken can launch his at varying angles, depending on the strength of the punch button, and can charge up to make it a two-hit projectile. The EX version has him fire two, with one acting as an anti-air, and the other traveling normally. Oni's version of the move will "fizzle" out after a certain range, but if charged to the maximum, it can hit twice and will continue to fly without fading. The EX version of this attack does not need a charge, hits twice, and also continues to the end of the screen. When fought as bosses, both versions hit twice without requiring a charge.
In X-Men: Children of the Atom, this projectile is orange in color instead of the usual blue or purple. In Super Gem Fighter Mini Mix, a leveled Gohadoken appears as a black sphere and sports more electrical effects, making it similar to a Psycho Shot.
