Bass' design was made in mind to be a polar opposite of Mega Man's. Bass is adorned in black armor with gold lining. On his chest, there is a triangular blue purple crystal (with some artworks showing an "F" for "forte" engraved inside its center). He has purple stripes running down from his eyes and extending down his cheeks. He has distinct red eyes (usually with pink retinas). His helmet features large yellow fins that resemble that of a cobra and a cross-shaped blue jewel on the forehead.
