marplot
Ruins others' plans
A marplot is someone who spoils a plan through meddling or interference.
The word combines "mar" (to damage) with "plot" (a scheme), naming the person who ruins what others have carefully arranged: Every committee has its marplot who derails progress with objections.
The term is old-fashioned and literary.
