|“||I'm always trying to include at least one musical piece from the previous title to satisfy old Metroid fans. It's like a present for them. For example, the music we used by following this theory is the jingle when Samus appears on the screen, and the music we prepared as the present for Metroid fans are the pieces for the lava caves in Metroid Prime and underwater music for Metroid Prime 2.||„|
Samus Aran's Appearance Fanfare (サムス アラン登場ファンファーレ) plays every time Samus Aran starts the game or respawns from her Gunship or a Save Station. It appears in all Metroid games virtually unchanged; the one exception is Metroid II: Return of Samus, which instead uses part of that game's Title theme. It is first heard just seconds before gameplay starts in the original Metroid. The Nintendo Entertainment System version of the game had a different sounding version of the score than the Famicom Disk System version, which is closer to the fanfare heard in subsequent games. The version that appeared in Metroid Prime has since been used in Metroid Prime 2: Echoes, Metroid Prime 3: Corruption, Metroid Prime Hunters and Metroid: Samus Returns. In AR Games, the Prime variation of the theme plays when Samus's AR Card is scanned despite the fact that the model used is from from Metroid: Other M.
The name of the theme originates from Super Metroid: Sound in Action.
Metroid version (Famicom): 
- This version is included on the Super Metroid: Sound in Action CD as the beginning of Appearance Fanfare~Brinstar. This version is also heard in Super Mario Maker whenever Mario transforms into Samus via Mystery Mushroom. This is also included as the last track on the Samus Archives Sound Selection CD, where it is titled Samus Appears.
- This version, rearranged by Hip Tanaka, is called Start Sound (スタート音) and is part of a medley that includes the Brinstar and Escape themes.
- The theme is heard twice partway through Brinstar (Melee).
Smashing... Live! version: 
- The theme is heard twice halfway through Depth of Brinstar, as part of the orchestration of Brinstar (Melee).
- This version is titled Appearance Jingle (登場ジングル) in the Metroid Prime & Fusion Original Soundtracks. This version sounded deeper and more techno.
- This version is titled Samus Appears Jingle (レコード・オブ・サムス) in the Metroid Prime & Fusion Original Soundtracks. In Metroid Prime, it plays when Samus first lands on the Frigate Orpheon. In Echoes, it plays at the beginning of multiplayer matches as the stage is loading. In Samus Returns, it plays when Samus first lands on SR388, as part of the file internally named Movie Ship Landing.
- This version plays when the save file is resumed, as Samus is stepping out of the Save Station. This version is included in the Metroid: Samus Returns Nintendo 3DS Theme, heard when the Nintendo 3DS is started up or brought out of Sleep Mode. In the internal files, the Samus Returns version is titled Matad Jintojo, referencing the game's development codename, Project Matadora.
- This version is also heard in Super Mario Maker whenever Mario transforms into Zero Suit Samus via Mystery Mushroom.
The Greatest Video Game Music 2 version: 
- The theme is heard a few times in Super Metroid: A Symphonic Poem, an orchestral medley of Super Metroid themes. This version is quiet, beautiful, and serene, with a soft choir accompaniment by the Crouch End Festival Chorus.
Nintendo Land alternate version: 
- This version plays during mission 1 of Metroid Blast. The same orchestrated version also can be heard at the beginning of missions 2, 3, 6, 7 and 11 before segueing into Brinstar (Metroid), heard here: 
- The theme is at the beginning of Title (Metroid).
- This arrangement of the fanfare is heard whenever the Federation Force is rescued by Samus Aran, acting as her leitmotif in the game.
- The first variation is dark and sinister, heard just before the boss battle against the brainwashed Samus Aran. The second variation is mournful and depressing, heard after Samus is defeated.
- In Metroid Prime 3: Corruption, the theme only plays when Samus lands her gunship at a Landing Site, and does not play when starting a game or respawning unlike in Prime or Echoes.
