Star Force Big Bang (スターフォースビッグバン Star Force Big Bang?), shortened as SFB, is a special attack that can be used in Mega Man Star Force when Mega Man pulls off a counter in battle while in a Star Break form. The big bang appears in the form of an usable Battle Card - as with other cards gained through countering - with the Star Force insignia on it. It is used like a regular, screen-dimming Battle Card. Star Force Big Bang is the predecessor to both Link Force Big Bang and Noise Force Big Bang.
