Whereas a roster of eight Robot Masters would become the standard from Mega Man 2 onward, the original Mega Man featured six Robot Masters. A seventh Master, Bond Man, who used a time-stopping power similar to Flash Man from Mega Man 2, was conceptualized but eventually cut from the game. Fire Man, Elec Man, and Ice Man introduced a recurring theme of elemental Robot Masters that would carry through the entire franchise.
