Nonexistent Physiology

Summary
Nonexistent Physiology is the state of existing as "nothing". Through this ability a character can continue to "exist" whilst erasing it from the rest of existence in a sense. These types of characters are percieved as if they never existed to begin with

Variations

 * Physical Nonexistence: The physical form of a character doesn't exist in the same reality as one who does exist. Characters with this variation can be rememebered, thought of and even percieved. However physical attacks and most conventional abilities won't have an effect on the entity
 * Mental Nonexistence: A characters physical body can be interacted with and exists on the same reality as one who does exist. This variation makes the user unable to be remembered and or throught of by any means. In addition no prove of their existence can be retained
 * Selective Nonexistence: Users of this particular variation can select and choose who is capable of percieving their existence. A user can effectively make themselves nonexistence to those who isn't choosen to know about their presence
 * Absolute Nonexistence: A combination of both physical and mental, the user is completely wiped from existence and, until they deactivate the power, all traces of their being are removed from history, time, space, memories, and even reality. Physical evidence such as photographs and name lists do not serve any reminder, as people would simply believe it to be someone they have no knowledge of.

Limitations

 * Users may be rendered unable to interact with reality due to their very nonexistence nature
 * Void Manipulators may be able to effect them in some shape or form
 * Some users may have to set how much they exist in order to interact with reality
