Koopa's Theme

"Koopa's Theme" is the musical theme composed by Koji Kondo for Super Mario 64 that plays when fighting Bowser in Bowser in the Dark World and Bowser in the Fire Sea. The theme's title uses Bowser's Japanese name, despite the soundtrack releasing in the West both physically in 1996 as well as in Super Mario 3D All-Stars in 2020.
