Headbutt is Donkey Kong's Side Special move in Super Smash Bros. Global Apocalypse. As its name states, Donkey Kong performs a headbutt. By performing it on an opponent, Donkey Kong can plow his opponents into the ground, disabling them for a short period of time. It is very useful for combos, such as performing a Super Punch after using it.
