The former Overwatch agent known as Tracer is a time-jumping adventurer and an irrepressible force for good.

Lena Oxton (call sign: "Tracer") was the youngest person ever inducted into Overwatch's experimental flight program. Known for her fearless piloting skills, she was handpicked to test the prototype of a teleporting fighter, the Slipstream. But during its first flight, the aircraft's teleportation matrix malfunctioned, and it disappeared. Lena was presumed dead.
