Tracer is one of the Blind Bag characters in Lego Dimensions 2: The Rise of Enoch, from the Overwatch franchise.
Tracer is an adventurer and former agent of the international task force, Overwatch. Tracer is known for her piloting skills; after being a member of the British Royal Air Force, she became the youngest person ever inducted into Overwatch's experimental flight program. She was chosen to test the Slipstream, a prototype of a teleporting fighter; during the test flight, the Slipstream's teleportation matrix malfunctioned and Tracer was pronounced dead. She later reappeared, having been desynchronized from the flow of time, preventing her from keeping a physical form in the present until a scientist named Winston created the chronal accelerator, which gives Tracer control over her own time.
