Summary[]
Corruption is the ability to "infect" someone or something with one's power, making said person or thing into a different being or state of being than it was before. This ability can be similar to Mind Manipulation (and potentially some of its facets) or Possession, in that the opponent becomes what you want them to be, but normally, once infected, the "corruptor" doesn't have to do anything for the "corruptee" to become corrupted.
Corruption can possibly be done through the aforementioned methods, along with things such as Disease Manipulation, Biological Manipulation, Absorption, and more, but it can also be done in such a way that there's no other way to classify it other than corruption. Despite the negative connotation of the word "corruption", it's possible for this power to be used to make someone a better individual, though this is an incredibly rare application.
