Today's update on the Smash Bros. Dojo comes as a musical one with Metroid: Boss Battle Music added to the orchestrated collection of Nintendo themes.
This song appears in a variety of games in the Metroid series.It's the theme song for Samus's arch-nemesis, Ridley.
In the original game, most of the places where you heard this song were the sites of fierce battles.
As such, this arrangement features a suitable sense of cruelty and tension. It's magnificent!
