Angry that her watch, a family heirloom, is accidentally dropped and broken, a high school girl is transformed into Timebreaker by Hawkmoth, the series main villain.

As Timebreaker, she is able to stop time for those she touches, freezing them in place before they slowly fade out of existence. This touch steals her victims energy, eventually giving her enough power and speed that she can actually travel back in time and meet herself.
