The Bushin Gourai Kyaku (武神剛雷脚, Bushin Gourai Kyaku, "Martial God Great Thunder Legs"), also known as Shadow Barrage, is one of Guy's Super Combos in the Street Fighter Alpha series, exclusive to his A-ISM Super Combo Gauge. It is considered his most useful Super Combo in the series.
Executed by performing two quarter-circle forward motions and pressing kick, Guy barrages the foe with a fast series of punches and kicks from his regular moveset. However, they are all strung quickly together, and are quite deadly when they all hit. The level of the Super Combo used will determine the amount of hits, and the attacks in general (4, 6 and 7, respectively).
