Tracer is the call sign of Lena Oxton, a character who appears in Blizzard Entertainment's Overwatch franchise. The 2014 Overwatch Cinematic Trailer short was her first appearance overall. An April 2016 update for the crossover multiplayer online battle arena game Heroes of the Storm added her to its playable roster, marking her first inclusion in a video game. Shortly thereafter, she appeared in the first Overwatch game, a first-person hero shooter. She again appeared in its 2023 sequel, Overwatch 2.
In the Overwatch narrative, she is a peppy and energetic pilot of British origin. A damage-class hero in-game, Tracer has low health, but is highly mobile, being able to both teleport and time travel. Those abilities were caused by an accident that left her unable to maintain a physical form in the present until her friend and fellow Overwatch agent, Winston, invented the "chronal accelerator", a device that allows her to control her own time frame.
