This is the ability to psychically animate and direct detached body parts, at will.

Uses/Applications (Pros)

One with this ability could psychically detach body parts, at will. In addition, one could psychically animate detached body parts, at will. Furthermore, one can often psychically perceive the presence, location and/or condition of one's detached body parts, at will. One can also psychically direct the movements of one's detached body parts, at will. One could even, in most cases, psychically reattach detached body parts, at will.

Weaknesses/Limitations (Cons)

There are a number of obvious potential complications and shortcomings that can come of this superhuman ability. In some cases, the force animating the detached body part also covers the stump, protecting it from bacterial infection, though this is not guaranteed. There is also the chance that the user cannot perceive where their detached parts are, and thus the user relies on surveillance technology or the cooperation of allies to make sure parts get where they are intended to go.

Not to mention, ease of motion varies with each user; some can move them with relative ease, while others (ie zombies) have detached parts that must drag themselves along slowly; still others (ie Arm-Fall-Off Boy) have parts that are largely immobile, and only good for use as tools or weapons (while more advantaged users have parts that can function as scouts or even assist in combat).

Also, some users can only detach certain body parts (ie only the head, only a hand, only the arms, perhaps only a certain number of body parts at a time). Though, most limiting of all, certain users can only animate parts that have been forcibly (painfully) severed, or may not even be able to willfully reattach limbs once they have been severed.
