Executed by charging backward, then pressing forward and punch, Balrog performs a simple dash forward and follows-up with a straight punch using his opposite fist, with an accompanying "rush of wind" background sound effect.
The EX Special version introduced in Street Fighter IV has Balrog dash the entire stage length and gain Super Armor, but its default damage value remains unchanged. In Street Fighter V the EX version has Balrog perform two consecutive punches on hit.
This move can be treated as one of Balrog's best pokes. Essentially, Dash Straight can be used as a fireball. Properly spacing the dash punches is crucial to Balrog's neutral game. While they are unsafe at point-blank range, this attack is an effective and safe way to apply pressure, deal chip damage and stuff out many normal attacks. Even though this move doesn't result in a knockdown, Balrog gets positional and frame advantage on hit. This allows him to maintain offensive pressure or mix up throws to keep his opponent guessing.
The speed, damage, and distance traveled are determined by the strength of the punch button pressed. The Light version has the fastest startup, but covers only about a third of the stage's length. It also deals the least amount of damage. The Medium version deals slightly more damage than the Light version. It also reaches around half the stage in length, though the punch takes longer to come out. The Heavy version travels almost the whole stage and inflicts the most damage. However, it has the longest startup.
The Ligh version is the hardest to predict the safest on block if spaced correctly.. The Medium version is generally considered the best variation for its passable distance and decent punch lag. The Heavy version, while naturally being the strongest version and considered the best for retreating foes, it is also the most predictable, and easily taken advantage of with a fairly quick reaction.
In addition, every variation can be easily countered with another move (specially projectiles), unless mitigated by the EX version's Super Armor.
