Dr. Wily's factory.

Dr. Wily's robot factory is where Dr. Light and Dr. Wily created the Robot Masters. Dr. Wily fortified the entire factory and uses it as a hideout in his first attempt to conquer the world. It has a scrambling field up to avoid anyone from teleporting inside and is full of robots such as Big Eyes and Fleas. Mega Man fights against a yellow robot and a copy of himself in the factory, and captures Dr. Wily.

Later Mega Man, Cut Man and Ice Man search for Wily and Roll in the remains of the factory, and they fight against CWU-01P before leaving.
