Special Weapon

The Master Weapons are the signature weapon systems of the Robot Masters, as well as the Roboticized Masters. They are unique to each robot as each one is unique and no two robots share the same weapon (though some are similar). Due to Mega Man's programming, he can copy the Master Weapon of any Robot Master he wants. Though due to Mega Man's own wishes he has the data wiped from his system after each adventure.
