You can manipulate how fast time flows for you, in either direction, as much as you want. In other words, you can speed your perception and movement up to the point where time appears stopped, or slow it to the point where years pass in minutes, or more. You can interact with objects normally, as though they weren't frozen, or you can choose to have objects simply refuse to move. Strength is not increased despite your speed, but you can apply your normal force multiple times in a row for roughly the same effect. You are not able to rewind time with this power. If you speed up your perceptions, your aging is slowed to account for it in a way that you age as though the appropriate amount of time passed, instead of however much you experienced. If you are about to die, this power automatically stops time for you.
