Tracer

Bio
At a young age, Lena Oxton was accepted into Overwatch as a pilot under the call sign Tracer. Her skills made her an ideal candidate for the first pilot of the Slipstream, a fighter jet capable of teleportation. However, the Slipstream malfunctioned, giving Lena the world's first case of chronal disassociation. For several months, she would vanish and reappear at random and was completely intangible.

After months of research, Winston was able to design a chronal accelerator for Lena. The device not only cured the problems presented by her condition, but also allowed her to speed up, slow down, or even rewind her own time manually. Using these abilities, Tracer became a standard soldier for Overwatch, until the organization was shut down.

At the time of the Overwatch Recall, Tracer was in London. She was the first to contact Winston when he sent out the signal. She is later seen attending a very small Christmas gathering at Watchpoint: Gibraltar with Winston in Reflections.

In Alive, Tracer attended Tekhartha Mondatta's speech in King's Row. She tried to stop Widowmaker from assassinating him; however, she failed and was defeated when Widowmaker incapacitated her, which left her with a damaged chronal accelerator.

In the Cinematic Trailer, Tracer, having recovered from her defeat, worked with Winston to stop Widowmaker and Reaper from stealing Doomfist's gauntlet. Though the gauntlet was damaged, there were no casualties.
