Metroid Samus Returns Boxart

Boss Omega (as named internally), also known as Boss Battle 5[1], is a battle theme from Metroid: Samus Returns. It is composed by Daisuke Matsuoka.


Boss Omega plays during encounters with Omega Metroids. This is the most orchestrated Metroid boss theme in Samus Returns, with heavy emphasis on low brass melodies and shrill high strings.

Boss Omega appears to be a largely original composition, not based upon any of the songs composed by Ryoji Yoshitomi for Metroid II: Return of Samus. However, some of the melody bears semblance to the Omega Metroid territory theme from Return of Samus.[2] This may have been a deliberate reference by Daisuke Matsuoka, although this is not confirmed.
