Soul Manipulation is, simply put, the ability to control and affect souls, the disembodied spirit of other beings. The applications of such an ability may range from simply being able to manipulate others and their emotions to consuming souls and killing others with ease. Generally speaking, this ability ignores durability and can be used to easily kill other beings and harm spirits and other intangible beings. Without resistance to soul-based attack and manipulation, most characters are vulnerable to this.
While whether or not all characters in fiction have a soul or not is debatable, by default, this wiki assumes that they do unless otherwise stated. Naturally, characters without a soul are completely immune to soul manipulation.
