Transformation (a.k.a. Transubstantial Transfiguration) is the name given to a branch of transfiguration that focuses on deforming the physical features of an object. It is not to be confused with Trans-species Transformation, though that is a type of transformation.
It contains the following sub-groups all of which overlap with each other to varying degrees): Human Transfiguration, defined by and named for the target being a human being; Switches, which simultaneously exchange features between organism; and the aforementioned Trans-Species Transformations, which refer to transformations that change organisms from one species to another.
