@TheUnknowable

as a follow up to my previous post, i've actually found something i would like to have instead. let me know your opinion.

Black Hole Creation: 

The user can create a small (ranging from marble to car size for example. she would still be learning to properly use her powers.) black hole at any time or place that will absorb anything including light, matter, vacuum, gravity, and energy to turn them into nothing. The victim will be torn to shreds after being stretched, then compacted to a point of compression after entering the black hole. Then they would simply erase to nothing as body molecules, matter, and energy would be absorbed.

Limitations: 

Size - no larger than a car. 
Duration - she can only hold it open for ten seconds.
Resting Period: Must wait at least 30 seconds afterwards or else her ability to stabilize it will be thrown off.
Amount: No more than two since she has two hands.

thats about it ^^ any other limitations im forgetting?
