The Shinku Hadoken (真空波動拳 Shinkū Hadōken?, "Vacuum/True Void Surge Fist") is a Super Combo introduced in Super Street Fighter II Turbo. It is one of Ryu's 'trademark' attacks in the Street Fighter series, and several other variants of this move have appeared since its introduction.

The Shinku Hadoken is a large, multi-hitting Hadoken (the maximum usually being 5 hits) made of vacuum energy. Its power propels it the length of the whole stage, and easily lets it plow through other weaker projectiles, though some games lower the amount of hits landed for each one it 'breaks', introducing the concept of "projectile durability" in certain fighting games.
Ryu has had the Shinku Hadoken as a Super Combo ever since it was introduced Super Street Fighter II Turbo, where it was referred to as "Burst Fireball" or "Vacuum Fireball". Sakura has also been able to use the Shinku Hadoken in most, if not all, of her appearances, and sometimes has an anti-air variant. Akuma possesses the more lethal Messatsu Gou Hadou, while Dan has his own version called the Shinku Gadoken and Sean also has a version called the Hado-Burst, which is the only way he can shoot any form of a Hadoken.
In the Street Fighter IV series, it reappears as Ryu's Super Combo and Sakura's second Ultra Combo. Sakura has two versions of the move: a standard ground version which is performed using the 3 punch buttons, and the anti-air version which is performed using the 3 kick buttons. The variants are called Shinku Tengyo Hadoken (真空天仰波動拳 Shinkū Tengyō Hadōken?, "Vacuum Heaven Seeking Surge Fist") and Shinku Soku Hadoken (真空蒼空波動拳 Shinkū Sōkū Hadōken?, "Vacuum Pale Air Surge Fist"). The move's versions are adapted from her use of the move in the Marvel vs. Capcom series.
Crossover apperancesIn the Marvel vs. Capcom series and other crossover games, it appears as one of Ryu and Sakura's Hyper Combos. In some games, the Shinku Hadoken takes the form of 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. Sakura's variant is an exception, as she fires continuous blasts diagonally upward, though it is performed 'normally' (i.e. the same as Ryu's) in her "Sunburned" form.
In X-Men vs. Street Fighter, when Ryu and Ken are on 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 appears in Marvel vs. Capcom 3 as one of Ryu's Hyper Combos; here, it can be fired in multiple directions and directed while firing as well. 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 Hadōken?, "True Surge Fist"), and it gains the ability to bounce off of walls.
In Super Smash Bros. for Nintendo 3DS and Wii U, Ryu's Final Smash will be the Shinku Hadoken if there are no opponents within striking range. Here, it has the ability of drawing closer foes in its path before striking them away. If Ryu uses his Final Smash within close range of any opponent, he will use the Shin Shoryuken instead.
