With the eight robot masters all defeated, you will soon find that there are four more stages before you get to begin your assault on Dr. Wily's Castle. These are the Doc Robot stages, and are made up of bits and pieces of stages you've already seen, but with modifications that make them far deadlier. Not only that, but there are two robot masters in each stage. Though they don't look different, really, they are taken from Mega Man 2. Only this time, your selection of weapons is different.
