Jett is an aggressive agent who has a distinctive, sarcastic personality. Her abilities include a teleportation-based dash and an updraft that lets her reach higher ledges. She also has a smoke bomb ability to hinder sightlines and a powerful Bladestorm ultimate that deals moderate-to-heavy damage and remains accurate even while she's moving.
