This is actually a thing in JoJo's Bizarre Adventure (Crazy Diamond). It's fun to see how they can make up cool scenarios with it:

Feats of this nature include trapping an enemy by restoring pieces of a broken crate around him; exposing a Stand formerly bound to an object; and tracking by restoring a severed hand, forcing it to seek out and reattach itself to the body from which it was cut off.
