In Echoes, the theme is heard during various points whenever Dark Samus is present and/or nearby. It is part of the "Dark Samus Appears Part 2" medley of themes. It is also heard when Dark Samus attempts to steal Samus's Light Suit after being defeated in the Sky Temple Grounds at the end of the game.
Corruption features the track in various scenes involving Dark Samus, including her resurrection within the Colossus at the beginning of the game, before she ambushes Samus, Rundas, Ghor and Gandrayda on Norion, and each time she absorbs one of the latter three Hunters, after Samus defeats them. Its final appearance occurs when Dark Samus is about to fight Samus herself on Phaaze.
