Bass

Bass (フォルテ, Forute?, Forte in Japan) is a robot designed by Dr. Wily in the Mega Man Classic series. He was constructed based on research conducted on Mega Man with the intention of matching his power in Mega Man 7. Wily makes mention of discovering the energy that powers Bass, Bassnium ("Forutenium" in Japanese), the most powerful form of energy on Earth, entirely by mistake.

Despite being created by Wily, Bass frequently rebels against his creator when he feels Wily is standing between him and defeating Mega Man.

Bass is the "brother" of Zero, since they share the same creator.

Bass's weapon is the powerful Bass Buster, which originally functioned similarly to the Mega Buster, albeit with slightly different shots. As of Mega Man & Bass, however, the Bass Buster has lost its ability to charge its shots in favor of a drastically increased rate of fire, as well as the capacity for upgrades that may make the shots stronger or pierce walls.

Like Mega Man and Proto Man, Bass can also copy the weapons of Robot Masters, his body changing colors to reflect the weapon currently equipped. He can also combine into a Super Form with his lupine companion Treble, allowing Bass to take flight and shoot more powerful projectiles from his buster.
