BrotherBand

BrotherBands
BrotherBands are a recurring theme in the MegaMan Star Force series. They are bonds formed by close friends using EM waves. When two people form a BrotherBand, they can contact each other at any time. They also learn their friend's secrets so BrotherBands are only formed by people that really trust each other.
