Fan Casting Shapeshifting in Characters Sorted by Powers

Users can change their shape, size, color, density, texture, cellular composition, and/or atomic composition to mimic qualities, impersonate entities, amplify abilities, and/or traverse environments. The origins of this power play a significant role in their capabilities and limitations; altering oneself on a cellular, atomic, and/or conceptual level will permit varying degrees of alteration; while methods that defy the laws of reality, such as magic, will most likely keep to their own set of conventions.
