Tracer has attracted media coverage related to online controversies surrounding one of her in-game victory poses, as well as her prominence in fan-produced pornography, which Blizzard has tried to remove. She is prominently featured in the game's official media, including promotional works and the game's cover art and appears in fan art. Tracer is one of the most recognizable Overwatch characters. Those abilities were caused by an accident that left her unable to maintain a physical form in the present until Winston invented the chronal accelerator, a device that allows her to control her own time frame. In the game, Tracer has low health, but is highly mobile with her skills including a teleportation-like ability and time-travel. The character, who is of British origin, has been noted by video game outlets to be peppy and energetic. She was introduced as a playable character in an April 2016 update for the crossover multiplayer online battle arena game Heroes of the Storm, nearly a month prior to the release of Overwatch. Tracer was first seen in the 2014 Overwatch Cinematic Trailer short. Tracer is the alias of Lena Oxton, a fictional playable character who appears in the 2016 video game Overwatch-a first-person shooter developed by Blizzard Entertainment-and related animations and literary media.
