Bass Buster

Bass Buster, known as Forte Buster in Japan, is Bass' main weapon. In Mega Man 7 and the arcade games, Mega Man: The Power Battle and Mega Man 2: The Power Fighters, the Bass Buster has the same capabilities as the Mega Buster. It can fire green bullets and charged shots. However, in Mega Man & Bass, the Bass Buster loses its charge ability in favor of a drastically increased rate of fire and the ability to fire in 1 of 7 directions. The Bass Buster retained these changes in Rockman and Forte: Mirai Kara no Chousensha and in Mega Man 10. In Mega Man 10, the Bass Buster has the additional ability to disarm the shields of the Shield Attackers and Sniper Joes.
