Tracer, real name Lena Oxton, is a British damage hero in Blizzard's team shooter Overwatch, first released in 2016. Her line became her signature greeting in trailers, hero select and gameplay, closely tied to her time-jumping, high-speed playstyle. As Overwatch clips spread across YouTube, Twitch and meme edits, fans began lifting the audio as a standalone entrance sound. It remains popular because it is instantly recognisable, short enough for quick edits, and works outside the game as a playful way to announce that help has arrived.
