Overwatch – Tracer Pocket Pop! Vinyl Keychain. Overwatch is the highly-successful shooter from Blizzard where, in a time of global crisis, an international task force of heroes banded together to restore peace to a warn-torn world. It ended the crisis and helped to maintain peace in the decades that followed, inspiring an era of exploration, innovation, and discovery. But after many years, Overwatch’s influence waned, and it was eventually disbanded. Overwatch is gone but the world still needs heroes. This Pocket Pop! Vinyl Keychain features Tracer, a former Overawe agent and time-jumping adventurer. She was the youngest person ever inducted into the Overwatch experimental flight program because of her fearless piloting skills.
