Mega Man Battle Network 5 is a game from the Mega Man Battle Network series released for the Nintendo Game Boy Advance in two versions: Team ProtoMan, known in Japan as Team of Blues and Team Colonel, known in Japan as Team of Colonel. Like Mega Man Battle Network 3, in Japan, ProtoMan was released by itself first with Colonel coming out months later. Despite that, Colonel contains the same bugs ProtoMan had.
A few months later, Mega Man Battle Network 5: Double Team DS was released for the Nintendo DS which included content from both GBA versions together with extras and bugfixes. A sequel and the finale game in the Mega Man Battle Network series, Mega Man Battle Network 6, was released the following year.
