 <unk> , Mega Man & Bass uses many of the same two @-@ dimensional sprites and animations as Mega Man 8 . Two of the eight Robot Master bosses in Mega Man & Bass ( Tengu Man and Astro Man ) are borrowed from Mega Man 8 . The other six were newly created for the game by three character designers : Hitoshi <unk> ( credited as " H. <unk> " ) , <unk> Iwamoto ( credited as " <unk> Iwamoto " ) and <unk> <unk> ( credited as " K. <unk> " ) designed two characters each . The bosses were officially unveiled on a teaser page in the Kodansha magazine Comic <unk> . Each boss was given distinct characteristics so that they could be easily identified by players in both their aesthetics and personalities . Some of these characters had different names during their conceptual phase prior to the <unk> of the game . " <unk> Man " became Burner Man , " <unk> Man " became Cold Man , and " <unk> Man " became Dynamo Man . Iwamoto originally denoted Ground Man as " <unk> Man " despite there already being a Robot Master by that name in Mega Man 4 . The musical score for Mega Man & Bass was composed by <unk> Kaida ( credited as " A. Kaida " ) , <unk> <unk> ( credited as " N. <unk> " ) , and " <unk> @-@ <unk> " ( real name unknown ) . Rather than create tracks together , each composer was responsible for their own songs . Kaida would later work with other composers in the Mega Man series on the soundtrack for Mega Man 10 , released in 2010 .
