The person proving your plan wrong before reality gets the chance to.
means An opponent or enemy actively working against you in a conflict, contest, or argument.
from From Latin adversarius, 'one turned against,' built on adversus, 'facing, opposed' — itself from ad- ('toward') plus vertere ('to turn'). So an adversary is literally someone who has turned to face you, squarely, as a foe rather than a bystander.
