Ana is a support hero in Blizzard's Overwatch, and her ultimate, Nano Boost, has been part of the game since she joined its roster in 2016. The ability's audio quickly became shorthand among players for a decisive boost, and clips of it spread through gameplay montages, streams, and short-form edits. It remains popular because the cue is instantly recognisable to Overwatch fans and clearly signals that a fight is about to turn.
