Hissho Buraiken (必勝無頼拳, Certain Victory Villainy Fist) (alternately spelled "Hisshou Buriaken") is a powerful Super Combo belonging to Dan. Its input and other details have changed over the course of the series.
Street Fighter Alpha series
Input: 
+ 
In this short ranged Super Combo, Dan flashes and holds his arms back for a few seconds, and then unleashes a very fast barrage of punches and kicks to the foe unfortunate enough to be within the range of this attack, ending with a Koryuken.
This attack has extremely low range, barely stretching just in front of Dan. Though his most powerful attack, it is often unreliable, as if the Dan player is short even the slightest inch, the foe will be completely unaffected (unless they are within the range of the Koryuken at the end.
Street Fighter IV series
Hissho Buraiken
Input: 
+
The Hissho Buraiken is Dan's Super Combo.in the Street Fighter IV series. It is executed differently than in the Alpha series, i.e. by performing two quarter-circle forward motions and pressing punch. Dan shouts "Victory is mine!" and unleashes a flurry of punches, kicks, knees and chops, finishing with a Koryuken while shouting "Take that!". Like Ken's Shinryuken, the attack works only at extreme close range and will miss if performed at any distance. It is a 19-hit combo if performed correctly.
Shisso Buraiken
Input: +
The Shisso Buraiken (疾走無頼拳, Sprinting Villainy Fist) is an advanced version of the Hissho Buraiken, and is Dan's first Ultra Combo. Executed by performing two quarter-circle forward motions and pressing all three punch buttons, Dan shouts "Special!" or "Saikyou-ryuu Ougi!" (depending on which language setting the player has) and, if successful, punches his opponent in the face, proceeding to launch a barrage of blows and finishing with a Koryuken while shouting "Wahoo!" or "Yahoo!" (English and Japanese settings respectively). As he lands, he performs his trademark pose: smiling broadly at the camera with a sparkling sound effect, giving a thumbs up and sticking his rear end out. Unlike the Hissho Buriaken, the attack has a wide distance (about the length of his Fierce Gadouken command) that will connect and will miss if performed at any distance farther than that, or if the opponent has almost hit the ground (during a Focus Crumble, Dan can still connect if his opponent's torso is a centimeter from hitting the ground, though the timing is tricky if done from a back dash). It is an 8-hit combo if performed correctly. It is also important to note that missing the attack will Dan open for a considerable amount of time, probably devastating the player to grabs and devastating combos.
