Aurora Unit 313 is the theme that plays during the final battle with the boss of the same name in Metroid Prime 3: Corruption. It is a remix of Darkness, Dark Samus's theme from Metroid Prime 2: Echoes, but is arranged to resemble the Zebetite theme from Metroid and Metroid: Zero Mission, owing to the Aurora Unit's resemblance to Mother Brain.
The theme is slow and ominous during the initial phase of the battle, but becomes faster and gains an alien-sounding melody when the Unit becomes airborne.
The theme can be heard here.
