Game: Mega Man 7

In the year 20XX, thanks to the efforts of Mega Man and his friends, Dr. Wily was finally brought to justice after several years of battles, much to the delight of the world. The people breathed a long sigh of relief as the jail cell door on Wily's cell was shut, hopefully for good... However, Wily had planned for just such an occasion. He had always known that one day, his plans might come to an end at Mega Man's hands, and so he had constructed four backup Robot Masters in a hidden lab. If they did not receive a communication from their master within six months, they would activate... and begin searching for their master. After six months, the robots activate and carry out their intended function, going on a rampage through the city Dr. Wily was being held in and carving a path of destruction in their wake.
