Antimatter

Introduction

 * Antimatter is any material that is composed of antiparticles, which have the same mass as regular particles, but with opposite physical charges. For example, the antiparticle of an electron is called the antielectron (positron), where this specific particle has a positive electric charge instead of a negative one.
 * When matter and antimatter come into contact with each other, they end up going through a process called annihilation, which results in a large amount of release in energy, depending on the amount of matter (and equal parts of anti-matter) involved in the reaction. The amount of the energy that is released is usually proportional to the total mass of the collided matter and antimatter, according to the mass-energy equivalent equation
 * The existence of our current universe means that the amount of matter vastly exceeds the amount of antimatter in comparison, even though both matter & antimatter were supposed to have been produced in equal amounts. This would mean that both matter & antimatter would collide with each other and "annihilate" themselves as a result. The existence of the current universe indicate that the interaction between matter & antimatter work differently.

Guidelines

 * Note that the amount of energy that is released is generally equivalent to the total mass of the mass & antimatter involved in the reaction process, which can be solved by: Energy = (Mass) x (Speed of Light^2)
 * The above is what is called the mass-energy equivalent equation
 * Note that the presence of antimatter must be directly present prior to the reaction before an approximate amount of energy can be calculated from the feat (that involves some sort of annihilation).
 * Feats that only involve the complete erasing of matter do not qualify for this, as the presence of antimatter is not mentioned, thus no quantifiable physical reaction had occurred.
 * In occasion, characters who have not been shown to have a proficient manipulation of antimatter (or just composed of ordinary matter) can interact with antimatter objects & realms without any sort of disintegration or damage.
 * This is either due to the author not understanding how the concept of antimatter works when interacting with matter, or the entire concept of matter & antimatter interaction is ignored to focus more on what is going on in the story.
