The Shinku Hadoken (真空波動拳 Shinkuu Hadouken?, "Vacuum 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.
|Marvel vs. Capcom series||Hyper Combo||+|
|Super Street Fighter IV||Ultra Combo II (for Sakura)|| + |
( + for anti-air version)
|Street Fighter X Tekken||Super Art (for Ryu)||+|
|All other appearances||Super Combo||+|
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'.
Ryu has had the Shinku Hadoken as a Super Combo ever since they were 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.
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 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 move's versions are adapted from her use of the move in the Marvel vs. Capcom series.
Crossover apperancesEditIn 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 Hadouken?, "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.
