—Akuma, since Street Fighter IV and all current medias except (Ultimate) Marvel vs. Capcom 3
Messatsu Gou Hadou is one of Akuma's Hyper Combos. Akuma fires a large purple Gou Hadoken beam to strike at the opponent. Cyber-Akuma also uses this move in Marvel Super Heroes vs. Street Fighter albeit it is dubbed as High Mega Gou Beam. Ryu also uses this move but only when he enters "Akuma Mode".
