A particularly frustrating form of a Diabolus ex Machina. The other characters' reactions usually range from shock to an anger burst. Double points if the MacGuffin can NEVER be replaced. In a story where The Good Guys Always Win, if the villain gets their hands on the MacGuffin, it's either taken from them or this happens.
Contrast Dismantled MacGuffin, where the MacGuffin is not broken, but is meant to be put back together. Often leads to No MacGuffin, No Winner. This only refers to objects, so a Living MacGuffin (obviously) does not count.
