Brother Band

Info
Brother Band is a system which connects 2 friends together through EM waves. Once you have one, you may trade data and send mail no matter where you are. In the first game, you'd have to find someone who has the one of 3 versions of Mega Man Star Force, battle him or her, and choose where to register that Brother. And once you form one, you'd have to find that Brother again, and go "On Air." But, in the second game, you have an Auto Brother, which is if you input a friend or family member's data, you can have that person appear in the game and Brother Band with you. Basically, it's the next best thing until they have the real thing. Transers, Star Carriers, Brother Bands. Some imply that we may get those things in the future, with better technology.
