based on the Infinity Stones: There are a set of stones that give supernatural powers: Time stone: can rewind, fast forward or stop time Mind stone: mind control and mind reading. Vision stone: x-ray vision and/or invisibility. Telekinesis stone: can manipulate objects and bodies. Get all of them, and you can alter reality.
There are a number of stories with a similar premise. One twist that I think could be fun is to split the stones up between characters and having them use their powers on each other.
Not a bad start for a story. That could prove interesting... Though the mind stone would have the advantage with that aspect. Control the mind-stone, and you control reality, assuming you have access to the other stone wielders. You need to make sure that each stone has their limits, advantages, and disadvantages in order for the story to be interesting.
Not necessarily as it might be restricted to mind reading or only allows to boost the feelings and to nudge another person into a certain direction.
