Executed by charging back, then pressing forward, back, forward and punch, Honda launches himself into two consecutive Sumo Headbutts. The speed, total invincibility and distance traveled during the headbutts are determined by the punch button pressed: light punch version travels the shortest distance at the slowest rate, with the most total invincibility; heavy punch version is the exact opposite of light punch; and medium punch version balances in-between.
In the Street Fighter Alpha series, Honda's level 3 Super Killer Head Ram adds an advancing Hundred Hand Slap at the end. This may have inspired the Ultimate Killer Head RamUltra Combo that appears in the Street Fighter IV series.
The technique reappears as part of Onigawara, under its original name of Oni-Muso. By pressing Heavy Punch and Heavy Kick upon hitting his opponent with Oni-Daikaku, Honda does a second headbutt in a similar motion as his former Super Combo.
