LiveandSound, Brutalties aren't special combos, they're conditions that need to be met to acomplish an instant kill finish. They usually need you to land the last hit with a specific move to initiate them. The opponent has to die from the last hit, which means that brutatities can only be done once a character is low HP and you have at least one out of two matches needed to win.
