The Metroid Prime 2: Echoes Theme is the theme of Metroid Prime 2: Echoes, playing on the Title Screen. A portion of this track plays during the Special Ending when Samus removes her Varia Suit before leaving Aether. Another portion is remixed for the post-credits ending where Dark Samus reforms herself above Aether. It also plays in the endings of Metroid Prime Hunters and Metroid Prime 3: Corruption. The Echoes theme is also used on the main page of Metroid.jp's Echoes site.
The Metroid Prime 2: Echoes Theme is used in a 2017 First 4 Figures video (viewable here) demonstrating the changes made to the sculpt of the new Varia Suit statue, since its original unveiling in 2016.
