Void Manipulation

Summary
Void Manipulation, also known as Nothingness Manipulation is the ability to manipulate the lack of existence, aka nothingness (a void). This field encompasses the control over things that essentially don't exist, such as voids or even being able to manipulate nonexistence itself

Note: Blackholes aren't considered voids, they have space in a inconventional sense. Additionally, Spatial Manipulation wouldn't fall under this as well

Possible Uses

 * Nothingness Manipulation: Users can effectively control the lack of existence within reality, aka nothingness. One who controls nothingness can often manipulate voids or draw from them, creating what is akin to a blackhole (but not exactly a singularity)
 * Existence Erasure: Users can often turn things that are considered existing into nothingness, causing them to not exist anymore. This can range from user, but often times, it erases every aspect of the opponent (body, mind and soul). Stronger users can even turn entire concepts into nothingness, making them not even exist anymore
 * Creation: Users can sometimes turn things that are nonexistence into existing things. This is considered one of the strongest forms of creation and usually stronger users can do this. Also note that doing this doesn't automatically prove Void Manipulation
 * Non-Physical Interaction: Some users can directly interact with nothingness, as if it was physically existing or akin to matter.  In essence, they could effect beings who normally would be inaccessible to beings who do traditionally exist and do whatever they want to them without either ceasing to exist or their attacks doing absolutely nothing

Limitations

 * What is considered existent and nonexistent can vary on verse, which means that the potency can range between series and that some users will be innately more potent than other users of the same skill
