Undo

Undo users can create, shape and manipulate nothingness, the absence of entities or substance; with this they can remove energy and matter from existence, by simply making things disappear, preventing energy from ever being conceived or via varied other means. They can control the essence of oblivion, allowing them to delete an eternity, removing targets from all timelines in every dimension, alter, reverse, or negate energy; etc. This could also lead to an ultimate goal of "destroying matter and energy" as in bringing it out of existence; or more accurately, flinging it into the metaphysical, otherwise known as causing microfractures to the Dreamlands to suck individuals through and into.
Far superior to Atleo, which merely tear targets gravitationally apart, this power allows to control the very nature of nothingness allowing the user to break any attack and defense since anything that comes into contact with it disappears irremediably without leaving any trace behind. This extreme offense leads to one massive downside, is that they invest all of their abilities in big shows of power, but skimp on the defensive side of things.   When going head to head with other highly destructive elements that don't need to hit you to effect you (like Love) Undo users tend to crumble extremely easy, which is why Shi's forces favor Atleo.
