Astra is a controller agent in Riot Games' tactical shooter Valorant, introduced in March 2021 as a Ghanaian agent who manipulates cosmic energy through her Astral Form. Like other agents, she received a distinctive selection cue for the pre-match lobby, where players choose their characters before a round begins. The short futuristic sound quickly became familiar to Valorant players and content creators, who reuse it to signal an Astra pick, introduce astral-themed edits, or set up gameplay highlights without needing any dialogue.
