@MrTree to clear this up, id still age normally, but not when paused, as time isn’t passing technically. And I would retain my memory when rewinding like Max from life is strange, so I’d essentially have knowledge of multiple timelines.
Also, absolutely. Those last few sentences are why it’s the best ability I can think of. It can essentially be used as a multitude of other powers, while still being its own thing.
Super speed, teleporting, super strong punches (technically if you got into the like science of it), knowledge, mock-mind reading, etc etc.
