Integrated circuit

Integrated circuit, I.C. for short, is an important part from Robot Masters. When Mega Man fights against a Robot Master, he takes great care to not damage their I.C. chip's "cognitive circuit". As long as the cognitive circuit isn't completely destroyed, Robot Masters can be rebuilt any number of times.
