Her personality was designed as heroic and happy. "Overwatch" game designer Michael Chu said, "the thing about Tracer is that she has a personality which is out of the norm for most people. She is incredibly optimistic, she is incredibly bubbly - it's part of her hero persona. We love her, I think she is very much one of the main characters of the game [...] [to] really carry the torch of what the game is all about: heroism." She is British and the British actress Cara Theobold voices her in the game.
