The Shakunetsu Hadoken (灼熱波動拳 Shakunetsu Hadouken?, "Scorching Heat Surge Fist") is the name of a special type of Hadoken introduced in the Street Fighter II series. It is used by Ryu, as well as his evil side, and Akuma.

Originally appearing as an animation glitch/bug that causes a Hadouken to randomly be colored red, many players assumed these mysterious "red Hadoukens" caused more damage than normal. Capcom then decided to make this official by officially adding in the Shakunetsu variation to Ryu's moveset.
Executed by performing a half-circle forward or backward motion, depending on the character, and pressing punch, the Shakunetsu Hadoken is imbued with thermal energy that sets it on fire.
Ryu's version is considerably less damaging than Akuma's, but Ryu does not charge when using it, thus making his version faster to pull off than Akuma's (about the speed of a regular Hadoken charge). It hits 1 to 3 times, and in certain games such as the Alpha series, it can knock a foe down at close range.
From Street Fighter III onwards, his version of the move does not appear directly, instead functioning as his two-hit EX Hadoken.
Akuma glows red and charges slightly before releasing it. The projectile hits 1-3 times, depending on the strength of the punch button; this also impacts recovery, with light punch recovering the fastest, and heavy punch hitting the most. Akuma's EX Special version hits three times, recovers as fast as the light punch version, and does some more damage. If executed with medium or heavy punch, it will knock down an opponent.
Akuma does not have this move in the Marvel vs. Capcom series. In the Street Fighter IV series, the alternate form of Akuma known as Oni has the Gorai Hadoken, a projectile imbued with electricity instead of thermal energy; its gameplay purpose remains largely the same as Akuma's Shakunetsu Hadoken.
In the Alpha series, Evil Ryu's version is similar to Ryu's: he does not charge when using it, and only hits 1 time. In Super Street Fighter IV, it retains its "charge" property, and functions largely the same as Akuma's, including the EX Special version.
Prior to Street Fighter IV, Akuma and Evil Ryu's versions could be nullified by another single-hit projectile, limiting the move's usefulness to 'chipping' an opponent on wake-up or forcing them to parry it (thrice) in the same scenario (Street Fighter III only). However, in the Street Fighter IV series, every hit of a projectile counts, allowing the heavy punch version to beat out regular and EX projectiles and still hit. Though this gives Akuma an option to win 'projectile wars' without using any meter, it requires him to preempt the opponent's moves, and is more often used for its chip damage.
