Time Manipulation
The power to control time, whether it be to stop it, accelerate it, reverse it, create fields that change its flow within, or whatever else have you. A very versatile ability with a lot of useful features. In stopped time, the user is essentially in their own world and can do whatever they like, usually creating confusion for those around them after time resumes. They can also reverse it and alter history, or accelerate it to have time fly faster. They can even erase time or events in more extreme cases. The possibilities of this power are perhaps endless.
