SAM is the armoured combat form of Firefly, a Stellaron Hunter in Honkai: Star Rail, the turn-based role-playing game from HoYoverse. The Supernova Overload name is tied to SAM's destructive, high-impact style, and clips of the sound have circulated among fans through soundboards and short-form edits. Creators keep returning to it because it instantly signals Firefly's power and the game's flashy combat, making it a recognisable shorthand for an all-out attack even for viewers who have not played the game.
