7. Dark Bowser Battle
Mario & Luigi: Bowser’s Inside Story
While Mario also has some great themes, his enemies also have their fair share of awesome tunes. The final battle against Dark Bowser in Bowser’s Inside Story is a truly awesome fight, and it has my favorite music out of all the battles in the Mario RPGs. I enjoy how the theme relies more on a piano melody instead of the typical rock instruments we hear associated with Bowser. It sort of sounds like you’d expect something out of a movie climax or action-packed montage. The fate of the entire Mushroom Kingdom, nay, the entire Mario universe, rests in your hands!
