Giga Cards are the most powerful Battle Cards in the Mega Man Star Force series. With this division being introduced the first game, they are all version-exclusive (except others mentioned in the list below), and cannot be traded. Players can only have one Giga Card in their folder, and the only way to put more in is to equip the program Giga Card +1. They are known for being able to unleash outrageous damage and effects in battle, causing the reason for their limitation.
