Each Robot Master has a "consciousness", although the level of every "cognitive circuit" embedded inside each one of them varies, producing as many different "personality" types as found in people. Like humans, they can speak, and have emotional responses like shyness or anger. When Mega Man fights against a Robot Master, he takes great care to not damage their integrated circuit chip's "cognitive circuit". As long as the cognitive circuit isn't completely destroyed, they can be rebuilt any number of times.
