Special Weapons are special combat devices belonging to the Robot Masters in the Mega Man comic series. Each weapon was assigned to a different Robot Master when Dr. Light and Dr. Wily first created them. However, Mega Man is able to obtain the weapons and use them for himself by copying the weapon data of the Robot Masters.
Each weapon matches the theme of the Robot Master it belongs to. For example, Fire Man owns a fire-based weapon called Fire Storm. Additionally, each robot is weak to a particular weapon; Fire Man, for instance, is especially vulnerable to Ice Man's Ice Slasher. This gives Mega Man an advantage when he utilizes the weapons himself to defeat the Robot Masters.
