Big Boss Confrontation BGM (Kraid, Crocomire, Phantoon)



Big Boss Confrontation (Kraid, Crocomire, Phantoon), as named on Super Metroid: Sound in Action, is a boss battle theme in Super Metroid. It is used during the battles with Kraid, Crocomire and Phantoon, and the encounter with the Big Metroid in Tourian. It is remixed in Metroid: Zero Mission, and used once again for the battle against Kraid. The theme in Zero Mission features a short introductory flourish when Samus steps into Kraid's chamber before flowing into the main theme. Notably, it also features piano strokes common in Metroid Fusion themes such as Sector 4 (AQA) Underwater Area.

It is one of two "Big Boss Confrontation" themes, the other, used for Ridley and Draygon (and the escape sequences), would be titled "Vs. Ridley" in later years, becoming that boss' signature battle music. The Mogenar boss and battle theme in Metroid Prime 3: Corruption resembles both Kraid and the Big Boss Confrontation theme, and may have been intended as an homage.

The original theme from Super Metroid can be heard here, and the remix from Zero Mission here.
