The Vulcan Punch is Ralf's unique ability.
In Metal Slug 6 & Metal Slug 7/XX, Ralf Jones can use this ability called the Vulcan Punch that sets out a series of punches. It is very powerful when used, and can even destroy vehicles in a couple of punches.
It is also worth noting that Ralf also used this move in the King of Fighters tournaments.
This attack appears in Metal Slug Defense too, as a close range attack.
