Tracer, of course!

The time-hopping poster girl of Overwatch!

Lena Oxton was once a promising young pilot tasked with flying the Slipstream-- An experimental fighter jet capable of teleportation! But when the test flight failed, and Lena vanished, it was assumed that tragedy had struck.

Only for Lena to reappear, years later, as a ghost!

In reality, Lena's accident had left her desynced from time. With a bit of tinkering, she was given a handy device that allowed her to control her personal time, allowing her to blink forward or recall in an instant!

With this handy ability and some laser pistols, Lena would go on to protect and serve the entire world as the face of Overwatch! An impressive feat...

Especially considering that she's never wearing clothes again.

Is this a personal choice by a cheeky lesbian? A product of her condition? Or maybe something else entirely!
