After many fights of Robot Master and their fusion forms, Dr. Nerd x Megaman Rock Force eventually comes to the final battle. This stage is separated from the first part to reduce some annoyance and pressure toward the stage itself by which the original game presented. Megaman is going to deal with the 8 main Robot Masters once again. After that, the battle with Justice Man (represented by Time Man) is waiting for him. The stage is now corrupted by some Pointan which is a result of Dr. Nerd (represented by Sheep Man) presence interfering with the stage as well as the second form of Justice Man. Though Megaman can get rid of Dr. Nerd, will he really stop his meddling with other stages by corrupting them? Only time can tell that!
