Shapeshifting covers both characters who can assume a variety of shapes and more limited shapeshifters.

If your character can shapeshift, you need to consider a number of factors.

What forms can your character assume?

Is your character limited to humanoid forms?

If your character can assume non-humanoid forms, how does he or she retain his or her human intellect?

Can your character assume an inanimate form, or a plant form?

How often can your character change shape?

How fast does it take your character to change shape?

Can your character shift from one shape to another, or must he or she return to their natural shape between forms?

If your character can turn into multiple forms, how does your character know those forms?

How long can your character remain in any given form?

How much effort does it take for your character to shapechange?

Can shapes be invented or varied from the template or imagination, or must they be identical to the copied form?

How many shapes can your character assume total?

How much can your character alter his or her mass when changing shape?

Where does the excess mass go, and from where is the extra mass gained?

Can your character copy physical enhancements?

Can your character copy powers?

Does your character's psyche change with the shapeshifting?

Shapeshifting is also related to mimicry.
