Battle Cards (バトルカード, Batoru Kādo) are cards used by people in the Mega Man Star Force series to delete EM Viruses. They are the successor to the Battle Chips from the Mega Man Battle Network series. Like Battle Chips, they are categorized into Standard, Mega, and Giga Class, and are used by swiping them through one's Terminal. Characters with EM Wave Change can use Battle Cards as weapons. In-battle, the Battle Cards are drawn up in a 3x2 fashion. Normally, Mega Man can only select Battle Cards
