Quirk: Time warp Type: Emitter

The user can bend his reality of time, appearing faster than those around him. This includes both speeding or slowing down time around him.

Limitations He can bend time to a max of 3x faster or slower, and can constantly warp time for a max of 5 minutes (the length of time the quirk can be used is of the perspective of the user, for example, if the user bends time so that he is 2x faster than normal, he could keep the time warp for 2.5 minutes in the perspective of natural time.) These limitations are not concrete and can be extended through training.

Weakness Once the user has ended time warp, the laws of time snap back like an elastic, causing the user to become time warped in the opposite. For example, if the user alters time so that he is 3x faster for 10 seconds in natural time, once the user exits the time warp he will immediately become 3x slower for 10 natural seconds.

With this in mind the user will often slow down his time if he is preparing for a fight or something where becoming slow after the warp will put him in danger. This way when he releases his time warp he become faster and will have no consequences afterward.
