Time stoping works on anything that flows through time.

@Captain Slumber Do ghosts and other spiritual beings flow through time?

I suppose; unless they're allowed to enter a dimension where time doesn't flow, then yes.

@Captain Slumber The Astral Plane is timeless and it's where spirits come from. Why do you think that an immaterial being is subject to time?

Unless they're specifically unbound by the passage of time, then yes. (just pretend this wasn't edited for the sake of goku soloing ok?)

@FeRNdawg626 Continue your crusade, my good soldier. For Goku! XD

It should work. Unless time does not restrict them.

@Abdalla1234 It depends. On Supernatural, their spiritual beings are capable of moving in stopped time.
