Quadraxis is the theme that plays while battling the boss of the same name in Metroid Prime 2: Echoes. It is slightly similar to the Ing Battle theme, but the tone and beat are much different, being more slowly-paced and with mechanical sound effects. In Metroid Prime Trilogy it is one of the songs available for purchase in the Soundtrack Gallery. It was composed by Kenji Yamamoto.
The theme can be heard here.
