 One has shown to possess near limitless levels of power. She is shown to have near unrestricted control over fundamental forces including space, time, matter, and energy, and she is seemingly able to grant any request made in her deals, like granting a person new limbs or restoring someone's original personality. She was able to return reality to a more stable state before the Rift in Space-Time opened, seemingly with just a snap, and overall One has been shown to be able to do nearly anything.
