|“||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 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, apart from Metroid II: Return of Samus which uses a different tune. 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 is included as the last track on the Samus Archives Sound Selection CD, included with the Special Edition of Metroid: Samus Returns.
- This version, rearranged by Hip Tanaka, is called Start Sound and is part of a medley that includes the Brinstar and Escape themes.
- This version is titled Appearance Jingle in the Metroid Prime & Fusion Original Soundtracks. This version sounded deeper and more techno.
Metroid Prime, Echoes, Corruption, Hunters and Samus Returns version: 
- This version is titled Samus Appears Jingle in the Metroid Prime & Fusion Original Soundtracks.
Metroid Prime and Samus Returns alternate version: 
- This version plays when the save file is resumed, as Samus is stepping out of the Save Station. The above version is heard only when Samus first lands on the Frigate Orpheon (Prime) and SR388 (Samus Returns). The alternate 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 Jinjojo. "Matad" is a reference to the game's development codename, Project Matadora.
Metroid: Other M version: 
The theme is also heard in Brinstar (Melee) and Title (Metroid) in the Super Smash Bros. series. An orchestrated version is used at the beginning of missions 2, 3, 6, 7 and 11 of Metroid Blast in Nintendo Land (heard here). A short, depressing version of the theme is used after Samus's defeat during the battle against her in Metroid Prime: Federation Force, which can be heard here.
- 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.
