- "The ultimate form of wave motion attack...Shinkuu...the power of vacuum energy!"
The Shinku Hadoken (真空波動拳, Shinkuu Hadouken, "Vacuum Surge Fist") is the name of a Super Combo used by Ryu, Sakura, and Ken (crossovers only in his case, as shown below). Ryu has had the Shinku Hadoken as a Super Combo (Hyper Combo in the crossovers) ever since Super Street Fighter II Turbo, where it was referred to as "Burst Fireball" or "Vacuum Fireball".
Several variants of the move exist: Akuma possess a very similar attack called the Messatsu Gou Hadou, while Dan has a parody version of this attack called the Shinku Gadoken. Sakura possesses a normal and anti-air variant, and uses them as Super and Ultra Combos; the variants are called Shinku Tengyo Hadoken (真空天仰波動拳, Shinkuu Tengyou Hadouken, "Vacuum Heavenly Command Surge Fist") and Shinku Soku Hadoken (真空蒼空波動拳, Shinkuu Soukuu Hadouken, "Vacuum Pale Sky Surge Fist").

The Shinku Hadoken, as with most Super Combos, are simply a bigger and more powerful version of a special attack. In this case, it is Ryu's Hadoken, only with one extra quarter-circle forward movement before pressing punch. The move itself is a large, multi-hitting Hadoken (the maximum usually being 5 hits) which transverses the whole stage, but it is also often easily jumped over. Via its name, it can be implied that vacuum space/empty air coats the exterior of the Hadoken fired, giving it extra power; thus through this the Shinku Hadoken often has a property that lets it break through any projectile, such as a regular Hadoken or a Tiger Shot, which usually catches foes by surprise. The move can easily be used for a combo by landing a standard Hadoken, and then performing the Shinku Hadoken. However, in regards to letting hit break through projectiles, there are times where it will lose a hit as it collides with one, paving way for projectile durability in later fighting games.
Super Street Fighter IVEdit
It makes its return in Super Street Fighter IV as Sakura's second Ultra Combo and Ryu's Super Combo. Sakura has two versions of the move: a standard ground and an anti-air version. The ground version is done using the 3 punch buttons, whereas the anti-air version is performed using the 3 kick buttons.
In the crossover games, the Shinku Hadoken is actually a large beam resembling the "Kamehameha" from the Dragon Ball series that lands even more hits, though the attack strength and dodging method remains unchanged.
When Ryu and Ken are in the same team, they can fire the Double Shinku Hadoken, which has Ryu and Ken fire the Shinku Hadoken together to overwhelm the enemy. This is the only means of access Ken has to the move.
The move most recently appeared in Marvel vs. Capcom 3 as one of Ryu's Hyper Combos; here, it can be fired in multiple directions. In Ultimate Marvel vs. Capcom 3, while under the influence of Hado Kakusei, the Shinku Hadoken becomes the Shin Hadoken (真波動拳, Shin Hadouken, "True Surge Fist"), and it gains the ability to bounce off of walls.
