- "This is not me. This is merely a form I must take to converse with you insignificant mortals."
- ― Ether, The Book of Deacon
- "As amazing as it seems, he can manipulate his body on the genetic level. The changes are instantaneous: everything, even the clothing is imitated. Tissue differentiated and transformed - on the fly. I want it on a slab. I need to know what makes it tick."
- ― Director McMullan on Alex Mercer, (PROTOTYPE)
- "I know I'm human. And if you were all these things, then you'd just attack me right now, so some of you are still human. This thing doesn't want to show itself, it wants to hide inside an imitation. It'll fight if it has to, but it's vulnerable out of the open. If it takes us over, then it has no more enemies, nobody left to kill it. And then it's won."
- ― R.J. MacReady (The Thing)

- Due to shapeshifters favoring certain forms for certain activities (e.g. bird-flying, fish-swimming), shapeshifters may be trapped and contained in places where only certain forms are feasible.
- May revert back to original form when unconscious or asleep.
- May require visual or genetic source material for a copy to be made.
- May be limited on how long transformation can last.
- May be unable to add/reduce mass, thus maintaining the physical capabilities of its original form.
- May have to stay near their own size.
- May have trouble with returning to original form.
- May be limited to humanoid shapes (human, werebeasts, etc).
- May be limited to organic lifeforms (animals, humans, etc.).
- May be unable to transform into complex machinery (vehicles, projectile weapons, etc.), being limited to only simple tools and melee weapons.
- May retain characteristics of their original form in their new shape (i.e., color scheme, markings, voice, smell, etc.).
- May only be able to partially imitate personality traits, thus people acquainted with the person being impersonated may get suspicious.
- May not be able to change genetic coding (meaning blood type, gender, and DNA coding), though this does not limit the user from changing into an animal, liquid form, and such.
- May be able to change DNA coding only partially.
- Staying extended periods in single form may start affecting the users' behavior or even make them forget their true self.
- Some users may be able to change forms (categorized as humans, cats, weapons, a body of water, etc.), but cannot shape that form into their own customization; instead, it must match their original form's shape.
- Such shape that cannot be altered include genetic coding (gender, hair color, blood type), physical appearance (such as a girl cannot change her facial or body structure to resemble another girl's, and while she can change into a cat her fur pattern is based on her own form) and design (such as the girl changing her body into a sword but cannot customize its design for decorative effects).
- This may not include the user's age, as it is an aspect of their original form.
- Users of Shapeshifting Awareness will see their real forms.
- Users of Shapeshifting Negation may forcefully revert the user to their real form.

- The process may be painful.
- May be involuntary; the user has no control over their transformations.
- Unless the user can absorb/modify their clothing during the transformation, they have to deal with it afterward.
- Clothing may be damaged during transformation unless it is part of the wearer's body or made of durable material.
