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.
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.
Akuma does not have this move in the Marvel vs. Capcom series.
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. This gives Akuma the option to win 'projectile wars' without using any meter, provided he can preempt the opponent's moves.
