Graphically , Mega Man & Bass use 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 was newly created for the game by three character designers : Hitoshi Ariga ( credited as " H. Ariga " ) , Yoshihiro Iwamoto ( credited as " Y. Iwamoto " ) and Koji Izuki ( credited as " K. Iduki " ) designed two characters each . The bosses was officially unveiled on a teaser page in the Kodansha magazine Comic BonBon . 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 finalization of the game . " Blast Man " became Burner Man , " Freezer Man " became Cold Man , and " Coil Man " became Dynamo Man . Iwamoto originally denoted Ground Man as " Drill 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 Akari Kaida ( credited as " A. Kaida " ) , Naoshi Mizuta ( credited as " N. Mizuta " ) , and " Kirikiri @-@ chan " ( 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 .
